TeamCity 9.0 Help

Installing and Configuring the TeamCity Server

This page covers a new TeamCity server installation. For upgrade instructions, please refer to Upgrade.

To install a TeamCity server, perform the following:

Installing TeamCity Server

After you obtained the TeamCity installation package, proceed with corresponding installation instructions:

  • Windows .exe distribution - the executable which provides the installation wizard for Windows platforms and allows installing the server as a Windows service;

  • .tar.gz distribution - the archive with a "portable" version suitable for all platforms;

  • .war distribution - for experienced users who want to run TeamCity in a separately installed Web application server. Please consider using .tar.gz distribution instead. .war is not recommended to use unless really required (please let us know the reasons).

Compared to the .war distribution, the .exe and .tar.gz distributions:

  • include a Tomcat version which TeamCity is tested with, so it is known to be a working combination. This might not be the case with an external Tomcat.

  • define additional JRE options which are usually recommended for running the server

  • have the teamcity-server startup script which provides several convenience options (e.g. separate environment variable for memory settings) and configures TeamCity correctly (e.g. log4j configuration)

  • (at least under Windows) provide better error reporting for some cases (like a missing Java installation)

  • under Windows, allow running TeamCity as a service with the ability to use the same configuration as if run from the console

  • come bundled with a build agent distribution and single startup script which allows for easy TeamCity server evaluation with one agent

  • come bundled with the devPackage for TeamCity plugin development.

  • may provide more convenience features in the future

After installation, the TeamCity web UI can be accessed via a web browser. The default addresses are http://localhost/ for Windows distribution and http://localhost:8111/ for tar.gz distribution.

If you cannot access the TeamCity web UI after successful installation, please refer to the #Troubleshooting TeamCity Installation Issues section.

The build server and one build agent will be installed by default for Windows, Linux or MacOS X. If you need more build agents, refer to the Installing Additional Build Agents section.

During the server setup you can select either an internal database or an existing external database. By default, TeamCity uses an HSQLDB database that does not require configuring. This database suites the purposes of testing and evaluating the system. For production purposes, using a standalone external database is recommended.

Installing TeamCity via Windows installation package

For the Windows platform, run the executable file and follow the installation instructions. You have options to install the TeamCity web server and one build agent that can be run as a Windows service.

If you opted to install the services, use the standard Windows Services applet to manage the service. Otherwise, use standard scripts.

If you did not change the default port (80) during the installation, the TeamCity web UI can be accessed via "http://localhost/" address in a web browser running on the same machine where the server is installed. Please note that port 80 can be used by other programs (e.g. Skype, or other web servers like IIS). In this case you can specify another port during the installation and use "http://localhost:<port>/" address in the browser.

If you want to edit the TeamCity server's service parameters, memory settings or system properties after the installation, refer to the Configuring TeamCity Server Startup Properties section.

Installing TeamCity bundled with Tomcat servlet container (Linux, Mac OS X, Windows)

Review software requirements before the installation.

Unpack the TeamCity<version number>.tar.gz archive (for example, using the tar xfz TeamCity<version number>.tar.gz command under Linux, or the WinZip, WinRar or similar utility under Windows). Please use GNU tar to unpack (for example, Solaris 10 tar is reported to truncate too long file names and may cause a ClassNotFoundException when using the server after such unpacking. Consider getting GNU tar at Solaris packages or using the gtar xfz command).

Ensure you have JRE or JDK installed and the JAVA_HOME environment variable is pointing to the Java installation directory. Oracle Java 1.7 JDK, and since TeamCity 9.1 JDK 1.8, is recommended.

Installing TeamCity into Existing J2EE Container

It is recommended to use the TeamCity .tar.gz distribution (bundled with Tomcat web server). .war distribution is not recommended unless there are important reasons to deploy TeamCity into existing web server.

  1. Copy the downloaded TeamCity<version number>.war file into the web applications directory of your J2EE container under the TeamCity.war name (the name of the file is generally used as a part of the URL) or deploy the .war following the documentation of the web server. Please make sure there is no other version of TeamCity deployed (e.g. do not preserve the old TeamCity web application directory under the web server applications directory).

  2. Ensure the TeamCity web application gets sufficient amount of memory. Please increase the memory accordingly if you have other web applications running in the same JVM.

  3. If you are deploying TeamCity to the Tomcat container, please add useBodyEncodingForURI="true" attribute to the main Connector tag for the server in the Tomcat/conf/server.xml file.

  4. If you are deploying TeamCity to Jetty container version >7.5.5 (including 8.x.x), please make sure the system property org.apache.jasper.compiler.disablejsr199 is set to true

  5. Ensure that the servlet container is configured to unpack the deployed war files. Though for most servlet containers it is the default behavior, for some it is not (e.g. Jetty version >7.0.2) and should be explicitly configured. TeamCity is not able to work from a packed .war: if started this way, there will be a note on this the logs and UI .

  6. Configure the appropriate TeamCity Data Directory to be used by TeamCity.

  7. Check/configure the TeamCity logging properties by specifying the log4j.configuration and teamcity_logs internal properties.

  8. Restart the server or deploy the application via the servlet container administration interface and access http://server:port/TeamCity/, where "TeamCity" is the name of the war file.

TeamCity J2EE container distribution is tested to work with Tomcat 7 servlet container. (See also Supported Platforms and Environments)

Unattended TeamCity server installation

For automated server installation, use .tar.gz distribution.

Typically, you will need to unpack it and make the script perform the steps noted in Configuring-Server-for-Production-Use section.

If you want to get a pre-configured server right away, put files from a previously configured server into the Data Directory. For each new server you will need to ensure it points to a new database (configured in <Data Directory>\config\database.properties) and change <Data Directory>\config\main-config.xml file not to have "uuid" attribute in the root XML element (so new one can be generated) and setting appropriate value for "rootURL" attribute.

Using another Version of Tomcat

If you want to use another version of Tomcat web server instead of the bundled one, you have the choices of whether to use the .war TeamCity distribution or perform the Tomcat upgrade/patch for TeamCity installed from the .exe or .tar.gz distributions. For the latter, you might want to:

  • backup the current TeamCity home

  • delete/move out the directories from the TeamCity home which are also present in the Tomcat distribution

  • unpack the Tomcat distribution into the TeamCity home directory

  • copy TeamCity-specific files from the previously backed-up/moved directories to the TeamCity home. Namely:

    • files under bin which are not present in the Tomcat distribution

    • delete the default Tomcat conf directory and replace it with the one provided by TeamCity

    • delete the default Tomcat webapps/ROOT directory and replace it with the one provided by TeamCity

Starting TeamCity server

If TeamCity server is installed as a Windows service, follow the usual procedure of starting and stopping services.

If TeamCity is installed using the .exe or .tar.gz distributions, the TeamCity server can be started and stopped by the teamcity-server scripts provided in the < TeamCity home >/bin directory.

  • To start/stop the TeamCity server and one default agent at the same time, use the runAll script, e.g.:

    • Use runAll.bat start to start the server and the default agent

    • Use runAll.bat stop to stop the server and the default agent

  • To start/stop the TeamCity server only, use the teamcity-server scripts and pass the required parameters. Start the script without parameters to see the usage instructions. Since TeamCity 9.1, the teamcity-server scripts support new options for the stop command:

    • stop n - Sends the stop command to the TeamCity server and waits up to n seconds for the process to end.

    • stop n -force - Sends the stop command to the TeamCity server, waits up to n seconds for the process to end, and terminates the server process if it did not stop.

By default, TeamCity runs on http://localhost:8111/ and has one registered build agent that runs on the same computer.

See the information below for changing the server port.

If you need to pass special properties to the server, refer to Configuring TeamCity Server Startup Properties.

If TeamCity is installed into an existing web server (.war distribution), start the server according to its documentation. Make sure you configure TeamCity-specific logging-related properties and pass suitable memory options.

Autostart TeamCity server on Mac OS X

Starting up TeamCity server on Mac is quite similar to starting Tomcat on Mac.

  1. Install TeamCity and make sure it works if started from the command line with bin/teamcity-server.sh start. We'll assume that TeamCity is installed in the /Library/TeamCity folder

  2. Create the/Library/LaunchDaemons/jetbrains.teamcity.server.plist file with the following content:

    <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>WorkingDirectory</key> <string>/Library/TeamCity</string> <key>Debug</key> <false/> <key>Label</key> <string>jetbrains.teamcity.server</string> <key>OnDemand</key> <false/> <key>KeepAlive</key> <true/> <key>ProgramArguments</key> <array> <string>bin/teamcity-server.sh</string> <string>run</string> </array> <key>RunAtLoad</key> <true/> <key>StandardErrorPath</key> <string>logs/launchd.err.log</string> <key>StandardOutPath</key> <string>logs/launchd.out.log</string> </dict> </plist>

  3. Test your file by running launchctl load /Library/LaunchDaemons/jetbrains.teamcity.server.plist. This command should start the TeamCity server (you can see this from logs/teamcity-server.log and in your browser).

  4. If you don't want TeamCity to start under the root permissions, specify the UserName key in the plist file, e.g.:

    <key>UserName</key> <string>teamcity_user</string>

The TeamCity server will now start automatically when the machine starts. To configure automatic start of a TeamCity Build Agent, see the dedicated section.

Installation Configuration

Troubleshooting TeamCity Installation

Upon successful installation, the TeamCity server web UI can be accessed via a web browser. The default address that can be used to access TeamCity from the same machine depends on the installation package and installation options. (Port 80 is used for Windows installation, unless another port is specified, port 8111 for .tar.gz installation unless not changed in the server configuration).

If the TeamCity web UI cannot be accessed, please check:

  • the "TeamCity Server" service is running (if you installed TeamCity as a Windows service);

  • the TeamCity server process (Tomcat) is running (it is a java process run in the < TeamCity home >/bin directory);

  • the console output if you run the server from a console,

  • the teamcity-server.log and other files in the <TeamCity home>\logs directory for error messages.

One of the most common issues with the server installation is using a port that is already used by another program. See below on changing the default port.

Changing Server Port

If you use the TeamCity server Windows installer, you can set the port to be used during installation. If you use the .war distribution, refer to the manual of the application server used.

Use the following instructions to change the port if you use the .tar.gz distribution. If another application uses the same port as the TeamCity server, the TeamCity server (Tomcat server) won't start and this will be identified by "Address already in use" errors in the server logs or server console.

To change the server port, in the < TeamCity Home >/conf/server.xml file, change the port number in the not commented "<Connector>" XML node (here the port number is 8111):

<Connector port="8111" ...

To apply the changes, restart the server. If the server was working with the old port previously, you would need to change the port in all the stored URLs of the server (browser bookmarks, agents' serverUrl property, URL in user's IDEs, "Server URL" setting on the "Administration | Global" Settings page).

If you run another Tomcat server on the same machine, you might need to also change other Tomcat server service ports (search for "port=" in the server.xml file).

If you want to use the https:// protocol, it should be enabled separately and the process is not specific to TeamCity, but rather for the web server used (Tomcat by default). See also Using HTTPS to access TeamCity server

Changing Server Context

By default, the TeamCity server is accessible under the root context of the server address (e.g. http://localhost:8111/). To make it available under a nested path instead (e.g. http://localhost:8111/teamcity/), you need to:

  • stop the TeamCity server;

  • rename the < TeamCity home >\webapps\ROOT directory to the < TeamCity home >\webapps\teamcity;

  • start the TeamCity server.

Java Installation

The TeamCity server is a web application that runs in an J2EE application server (a JVM application). TeamCity server requires a Java SE JRE installation to run.

TeamCity (both server and agent) requires JRE 1.6 (or later) to operate. Using Oracle Server JRE 1.7, and since TeamCity 9.1 JRE 1.8, is recommended (download page). It is recommended to use the 32-bit installation unless you need to dedicate more memory to TeamCity server. Please check the 64-bit Java notes before upgrade. If you configured any native libraries for use with TeamCity (like a .dll for using Microsoft SQL database Integrated Security option), you need to update the libraries to match the JVM x86/x64 platform.

For TeamCity agent Java requirements, check Setting up and Running Additional Build Agents.

The necessary steps to update the Java installation depend on the distribution used.

  • if your TeamCity installation has a bundled JRE (there is the < TeamCity Home >\jre directory), update it by installing a newer JRE per installation instructions and copying the content of the resulting directory to replace the content of the existing < TeamCity home >\jre directory.

    If you also run a TeamCity agent from the <TeamCity home>\buildAgent directory, install JVM (Java SDK) installation instead of JRE and copy content of JVM installation directory into < TeamCity Home >\jre.

  • if there is no < TeamCity Home >\jre directory present, set JRE_HOME or JAVA_HOME environment variables to be available for the process launching the TeamCity server (setting global OS environment variables and system restart is recommended). The variables should point to the home directory of the installed JRE or JVM (Java SDK) respectively and only one variable should be present.

  • if you use the .war distribution, Java update depends on the application server used. Please refer to the manual of your application server.

Using 64 bit Java to Run TeamCity Server

TeamCity server can run under both the 32- and 64-bit JVM. It is recommended to use the 32-bit JVM unless you need to dedicate more than 1.2Gb of memory (via -Xmx JVM option) to the TeamCity process (see details) or your database requirements are different.

If you choose to use the 64-bit JVM, note that the memory usage is almost doubled when switching from the 32- to 64-bit JVM, so please make sure you specify at least twice as much memory as for 32-bit JVM, see #Setting Up Memory settings for TeamCity Server.

To update to the 64-bit Java:

  • update Java to be used by the server

  • set JVM memory options. It is recommended to set the following options for the 64-bit JVM: -Xmx4g -XX:MaxPermSize=270m -XX:ReservedCodeCacheSize=350m

Setting Up Memory settings for TeamCity Server

As a JVM application, TeamCity only utilizes memory devoted to the JVM. Memory used by JVM usually consists of: heap (configured via -Xmx), permgen (configured via -XX:MaxPermSize), internal JVM (usually tens of Mb), and OS-dependent memory features like memory-mapped files. TeamCity mostly depends on the heap and permgen memory and these settings can be configured for the TeamCity application manually by passing -Xmx (heap space) and -XX:MaxPermSize (PermGen space) options to the JVM running the TeamCity server.

Once you start using TeamCity for production purposes or you want to load the server during evaluation, you should manually set appropriate memory settings for the TeamCity server.

To change the memory settings, refer to Configuring TeamCity Server Startup Properties, or to the documentation of your application server, if you run TeamCity using the .war distribution. Generally this means setting TEAMCITY_SERVER_MEM_OPTS environment variable to the value like -Xmx750m -XX:MaxPermSize=270m.

If slowness, OutOfMemory errors occurs or you consistently see memory-related warning in TeamCity UI, increase the settings to the next level.

  • minimum settings (the 32-bit Java should be used (bundled in .exe distribution)): -Xmx750m -XX:MaxPermSize=270m

  • recommended settings for medium server use (the 32-bit Java should be used): -Xmx1024m -XX:MaxPermSize=270m Greater settings with the 32-bit Java can cause OutOfMemoryError with "Native memory allocation (malloc) failed" JVM crashes or "unable to create new native thread" messages

  • maximum settings for large-scale server use (64-bit Java should be used): -Xmx4g -XX:MaxPermSize=270m -XX:ReservedCodeCacheSize=350m These settings will be suitable for an installation with more than a hundred of agents and thousands of build configurations. Custom plugins installed might require increasing the values defined via MaxPermSize and Xmx parameters

Tips:

  • the 32-bit JVM can reliably work with up to 1Gb heap memory (-Xmx1024m). (This can be increased to -Xmx1200m, but JVM under Windows might crash occasionally with this setting.) If more memory is necessary, the 64-bit JVM should be used assigning not less than 2.5Gb (-Xmx2500m). It's highly unlikely that you will need to dedicate more than 4Gb of memory to the TeamCity process.

  • A rule of thumb is that the 64-bit JVM should be assigned twice as much memory as the 32-bit for the same application. If you switch to the 64-bit JVM, make sure you adjust the memory settings (both -Xmx and -XX:MaxPermSize) accordingly. It does not make sense to switch to 64 bit if you dedicate less than the double amount of memory to the application.

The recommended approach is to start with initial settings and monitor for the percentage of used memory (see also TW-13452) at the Administration | Diagnostics page. If the server uses more then 80% of memory consistently without drops for tens of minutes, that is probably a sign to increase the memory values by another 20%.

Configuring TeamCity Server

  • If you have a lot of projects or build configurations, we recommend you avoid using the Default agent in order to free up the TeamCity server resources. The TeamCity Administrator can disable the default agent on the Agents page of the web UI.

  • When changing the TeamCity data directory or database make sure they do not get out of sync.

Configuring TeamCity Data Directory

The default placement of the TeamCity data directory can be changed. See corresponding section: TeamCity Data Directory for details.

Editing Server Configuration

After successful server start, any TeamCity page request will redirect to prompt for the server administrator username and password. Please make sure that no one can access the server pages until the administrator account is setup.

After administration account setup you may begin to create Project and Build Configurations in the TeamCity server. You may also want to configure the following settings in the Server Administration section:

  • Server URL

  • Email server address and settings

  • Jabber server address and settings

Configuring Server for Production Use

Out-of-the-box TeamCity server installation is suitable for evaluation purposes. For production use you will need to perform additional configuration which typically includes:
