sudo apt-get install jenkins

#建立 jdk 软连接
ln -s /opt/soft/jdk1.8.0_333/bin/java /usr/bin/java

#修改启动的端口
vim /lib/systemd/system/jenkins.service
#指定自己想要的端口
Environment="JENKINS_PORT=18080" 

systemctl daemon-reload
systemctl start jenkins

#启动
./etc/init.d/jenkins start
./etc/init.d/jenkins stop
./etc/init.d/jenkins restart

systemctl start jenkins
systemctl stop jenkins

#问题2：该Jenkins实例似乎已离线

#centos
#查看可用版本
yum list --showduplicates jenkins

#安装
yum install jenkins-2.346.1-1.1

#加载配置，启动
systemctl daemon-reload
systemctl start jenkins

问题：

#问题1：如果访问不了请检查防火墙，开放端口
#新增规则
firewall-cmd --permanent --add-port=18080/tcp 
#删除规则
firewall-cmd --permanent --remove-port=18080/tcp
#重新加载规则
firewall-cmd --reload
