1. 检查服务器包配置[可选]

一般不需要apt的额外配置, 如果有删除配置或者移动到别处, 使其不生效:

sudo rm /etc/apt/apt.conf

sudo apt-get update

2. 安装JDK

jenkins依赖java, 安装java8+版本,并且配置java_home:

sudo apt search openjdk

sudo apt-get install openjdk-8-jdk

sudo vim /etc/bash.bashrc
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/

3. 安装jenkins

在ubuntu环境下安装:

wget -q -O - https://pkg.jenkins.io/debian/jenkins.io.key | sudo apt-key add -
sudo sh -c 'echo deb http://pkg.jenkins.io/debian-stable binary/ > /etc/apt/sources.list.d/jenkins.list'
sudo apt-get update
sudo apt-get install jenkins

一些默认文件位置: |路径|描述| |---|---| |/etc/default/jenkins|jenkins运行配置| |jenkins|默认文件用户| |/var/log/jenkins/jenkins.log|日志路径| |/var/lib/jenkins/|jenkins home|

4. 高级设置

• Crowd 2 Integration
• 配置slave
  • 新建node
  • 配置node启动方式: 通过Java Web启动代理
  • 查看salve页面下载agent.jar 和 slave-agent.jnlp 文件, 并且放到salve服务器的jenkins_home目录下
  • 登录salve服务器切换到jenkins用户, 运行上一步salve页面执行命令, 如: java -jar agent.jar -jnlpUrl http://slave.server.ip:8080/computer/slave-01/slave-agent.jnlp -secret 2a99268dbfc5d5f4c517d237d48078b1163f -workDir "/var/lib/jenkins/"

5. 遇到问题

• 空白页面

  解决方式: sudo /etc/init.d/jenkins restart

• 配置agent的守护进程(否则java -jar agent.jar....命令中断后集群就垮了)

  sudo easy_install supervisor
  echo_supervisord_conf > supervisord.conf
  sudo mv supervisord.conf /etc/supervisord.conf
  sudo vim /etc/supervisord.conf # 修改include为files = /etc/supervisor/*.conf
  sudo mkdir -p /etc/supervisor
  sudo vim /etc/supervisor/jenkins-slave-agent.conf
  

  jenkins-slave-agent.conf:

  [program:jsa]
  directory = /var/lib/jenkins/
  command = java -jar agent.jar -jnlpUrl http://slave.server.ip:8080/computer/slave-01/slave-agent.jnlp -secret 2a99268dbfc5d5f4c517d237d48078b1163f -workDir "/var/lib/jenkins/"
  autostart = true
  autorestart = true
  user = jenkins
  redirect_stderr = true
  stdout_logfile = /var/lib/jenkins/jenkins-slave-agent.log
  

  supervisorctl commond:

  sudo supervisorctl reread # 读取新配置
  sudo supervisorctl update # 启动更新
  sudo supervisorctl status # 查看状态
  sudo supervisorctl stop jsa # 停止一个子进程
  sudo supervisorctl start jsa # 启动一个子进程
  sudo supervisorctl restart jsa # 重启一个子进程
