• 重新加载配置文件

systemctl daemon-reload

• 启动jenkins

systemctl start jenkins

• 设置开机启动

systemctl enable jenkins

升级

• 服务器上搜索jenkins.war，一般位置会在 /usr/lib/jenkins下

最新的版本中jenkins.war文件在/usr/share/java目录下面

find / -name jenkins.war 

• 将升级版本的war替换已有的war包

cd /usr/lib/jenkins

mv jenkins.war jenkins.war.2.235

cp /opt/jenkins.war .

• 重启jenkins

systemctl restart jenkins
