Howto install JetBrains TeamCity v6.5.1 on CentOS v5.x
This howto describes getting a TeamCity appliance up and running to the point that a web browser can be used to configure it. Installation of the a TeamCity Build Agent(s) is not covered by this howto.
Note:
- JetBrains recommends the use of a 32bit JDK. I exclusively use 64bit CentOS so using a 64bit JVM is the most straightforward option.
- JetBrains doesn't support OpenJDK. I have no idea why but I have had good success with TeamCity and the openjdk. I tend to use the supported JDK on Windows build agents.
Tasks
- Machine configuration
- Disk Partition
- MySQL
- OpenJDK
- Configure a reverse proxy in front of the TomCat server
- TeamCity
Machine Configuration
Prerequisite machine configuration information
- CentOS v5.x (machine name is olive)
- x86_64
- 1GB RAM, with 2GB swap
- 4 CPU's
- 8GB / (root) partition
- 32GB /srv partition for TeamCity data
- IPv4 and IPv6
- SMTP mailer (postfix)
- IPv4 and IPv6 firewall
TeamCity partition
The TeamCity server application comes as a binary blob. For simplicity this document describes putting it as a blob on it's own filesystem. This will grow with logs and artifacts. It should be sized based on the expected growth given the projects being managed by the server. Format the /srv partition with an ext4 filesystem:
# yum install e4fsprogs # mkfs.ext4 -L /srv /dev/xvdc1
Add the following mount entry to '/etc/fstab' and mount:
LABEL=/srv /srv ext4 defaults 1 2
MySQL
Install MySQL server
yum install mysql-server
Since the database is only required by local processes, ensure it only listens on the loopback interface in '/etc/my.cnf'. MySQL v5.1 didn't seem to want to run with an IPv6 loopback address.
[mysqld] bind-address = localhost
Enable and start services:
# for A in mysqld; do chkconfig $A on ; service $A start ; done
Install MySQL Java connector
This is distributed as part of the EPEL repository. Install the EPEL repository:
# rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
Install the connector:
# yum install mysql-connector-java
OpenJDK
Install openjdk from the CentOS repository:
# yum install java-1.6.0-openjdk
Firewall configuration
The Teamcity server will require the following network communications:
- incoming http to the Tomcat server on TCP port 8111
- outgoing http to TCP port 9090 on build agents
- outgoing XMPP to TCP port 5222
- outgoing SMTP to TCP port 25
Add the following rules to the IPv4 firewall rules:
# Teamcity server -A tcpIn -p tcp -m tcp --source 10.20.7.0/24 --dport 8111 -m state --state NEW -j ACCEPT # TeamCity Build agent -A tcpOut -p tcp -m tcp --dport 9090 -m state --state NEW -j ACCEPT # XMPP client -A tcpOut -p tcp -m tcp --dport 5222 -m state --state NEW -j ACCEPT
Reverse proxy
A caching reverse proxy is used in front of the TeamCity server. This provides:
- simplified external access through the firewall
- TLS/SSL offload
- TLS SNI extensions
- caching (varnish)
- unified access for IPv4 and IPv6
Nginx configuration
Add the following Nginx configuration file '/etc/nginx/conf.d/teamcity.lucidsolutions.co.nz.conf':
#
# TeamCity server
#
# All http traffic is redirected to https. The https traffic is proxied
# to the local varnish cache before going to the teamcity server on
# port 8111.
#
server {
listen [::]:80;
server_name teamcity.lucidsolutions.co.nz;
location / {
# redirect to secure page [permanent | redirect]
rewrite ^ https://teamcity.lucidsolutions.co.nz$request_uri? permanent;
}
}
server {
listen [::]:443;
server_name teamcity.lucidsolutions.co.nz;
keepalive_timeout 70;
ssl on;
ssl_certificate certs/teamcity.lucidsolutions.co.nz.startssl.crt;
# ssl_certificate certs/teamcity.lucidsolutions.co.nz.self-signed.crt;
ssl_certificate_key certs/teamcity.lucidsolutions.co.nz.key;
access_log /var/log/nginx/teamcity.lucidsolutions.co.nz.access.log main;
location / {
# proxy via the local varnish cache
proxy_pass http://localhost:6081/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
client_max_body_size 10M;
}
}
A public key certificate with the necessary certificate chain will need to be produced/procured. Test the configuration and then reload it:
# service nginx reload
Varnish configuration
Add a backend to the configuration:
backend TeamCity {
.host = "2001:4428:225:14::2";
.port = "8111";
}
Add a match on the URL and proxy to the backend :
if (...) {
...
}
else if ( req.http.host ~ "^teamcity.lucidsolutions.co.nz$" ) {
set req.backend = TeamCity;
}
Reload the varnish configuration with this script.
TeamCity
Read the JetBrains TeamCity installation instructions. The following directory structure is used by the TeamCity installation:
-+ srv
+- teamcity Home directory for the 'teamcity' user
+- 6.5.1 v6.5.1 installation directory (of the binary blob)
| +- bin
| +- logs Server log files are written here
| +- ...
+- .BuildServer This directory is created during the first start
+- config The server configuration
+- lib
+- plugins
+- system
+- artifacts The artifacts from the build server [this can grow]
+- ...
Unpack the archive
Download the tar.gz archive from JetBrains and extract it to the '/srv' directory:
# adduser -c "TeamCity Build Server" -m -d /srv/teamcity -r teamcity # su teamcity -c "tar -xpzf TeamCity-6.5.1.tar.gz -C /srv/teamcity" # mv /srv/teamcity/TeamCity /srv/teamcity/6.5.1
Init script
Add the init script '/etc/init.d/teamcity' from the appendix, and configure the init script:
# chmod +x /etc/init.d/teamcity # chkconfig --add teamcity
Add a configuration file for the init script to point to the team city package.
# cat > /etc/sysconfig/teamcity <<EOF TEAMCITY_SERVER_MEM_OPTS="-Xmx768m -XX:MaxPermSize=150m" TEAMCITY_DIR=/srv/teamcity/6.5.1 EOF
Start the teamcity server. It will start with it's internal database and create the '.BuildServer' directory with configuration files. The web interface should show the starting message.
# service teamcity start
MySQL setup
Use MySQL to store configuration information. Read the instructions for setting up an external database. Create an empty database using the root user (the mysql root user should be secured with a strong pass phrase, as well as the teamcity user):
# mysql mysql> CREATE DATABASE teamcity DEFAULT CHARACTER SET utf8; mysql> GRANT USAGE ON *.* TO 'teamcity'@'localhost' IDENTIFIED BY 'teamcity'; mysql> GRANT ALL ON teamcity.* TO 'teamcity'@'localhost'; mysql> flush privileges;
Use the sample database properties file '~teamcity/.Buildserver/config/database.mysql.properties.dist' to create the following '~/teamcity/.BuildServer/config/database.properties':
connectionUrl=jdbc:mysql://localhost:3306/teamcity connectionProperties.user=teamcity connectionProperties.password=teamcity maxConnections=50 # connectionProperties.useUnicode=true # connectionProperties.characterEncoding=UTF-8 testOnBorrow=true
The MySQL Connector driver must be present in the '.BuildServer/lib/jdbc/' directory. It isn't sufficient for this to be installed on the machine.
# ln -s /usr/share/java/mysql-connector-java.jar ~teamcity/.BuildServer/lib/jdbc/
Start TeamCity
The first startup of the TeamCity server will be lost in the embedded database. For a new installation there should be no information/content to migrate. Start the server with the mysql server backend:
service teamcity start
The empty database is detected by the TeamCity server.
Get the token from the log file '/srv/teamcity/6.5.1/logs/teamcity-server.log'.
Confirm the details:
The server takes a few seconds to start up
Confirm the license agreement
And create the first administrator user
