jenkins安装

1、sudo wget -o /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo 2、sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key 3、sudo yum install jenkins -y 4、systemctl start jenkins   注： 初始密码：cat /var/lib/jenkins/secrets/initialAdminPassword   jenkins默认会kill掉衍生的子shell进程，可通过在构建的脚本开头加上BUILD_ID=DONTKILLME   默认是jenkins启动服务，可在/etc/systemctl/jenkins中修改JENKINS_USER="user"后   sudo chown -R user:user /usr/lib/jenkins /usr/lib/jenkins/jenkins.war /usr/sbin/rcjenkins /var/cache/jenkins /var/lib/jenkins /var/log/jenkins   然后再重启jenkins服务   jenkins启动的时候可能会报错java环境找不到，可sudo vim /etc/init.d/jenkins中添加java的路径 例如：/usr/java/jdk1.8.0_45/bin/java
