Setting up a Hudson slave node

Redhat / CentOS 5

From a clean Redhat 5 or CentOS 5 install, do the following:

• Ensure SSHD is going to run
  • chkconfig sshd on
  • service sshd start
• Open SSH port 22 through iptables
  • system-config-securitylevel
  • set SElinux disabled
• Install MySQL 5
  • Note: caGrid 1.2 and earlier require MySQL 4.x
  • yum install mysql mysql-server -y
• Enable MySQL to start at boot
  • chkconfig mysqld on
• Edit MySQL config to use InnoDB as default engine (really any transactional engine is OK - NOT MyISAM), and max connections increased
  • http://dev.mysql.com/doc/refman/5.1/en/storage-engine-setting.html
  • Edit /etc/my.cnf
    • Add "default-storage-engine=InnoDB"
    • Add "set-variable=max_connections=250"
• Install SVN and CVS
  • yum install subversion cvs -y
• Install JDK 5 and 6
  • Typically to /usr/java/<JDK>
  • JDK 5 RPM: http://java.sun.com/products/archive/j2se/5.0_10/index.html
  • JDK 6 RPM: http://java.sun.com/products/archive/j2se/6u16/index.html
  • rpm -ivh XXX.rpm
• Increase max file handles
  • echo "fs.file-max = 65535" >> /etc/sysctl.conf
  • sysctl -p
  • edit /etc/security/limits.conf

    *                soft    nofile          65535
    *                hard    nofile          65535
    

  • add to /etc/pam.d/login

    session    required   /lib/security/pam_limits.so
    

  • Reload ssh config with service sshd reload
