[root@nmhs-pp-mw049181 ~]# yum install java -y
[root@nmhs-pp-mw049181 ~]# java -version
openjdk version "1.8.0_91"
OpenJDK Runtime Environment (build 1.8.0_91-b14)
OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode
[root@nmhs-pp-mw049181 ~]$ cat /etc/profile
#Jenkins
export JENKINS_HOME=/data/jenkins
[root@nmhs-pp-mw049181 ~]$ source /etc/profile

3.启动jenkins

[root@nmhs-pp-mw049181 ~]# nohup java -jar /data/jenkins/jenkins.war --ajp13Port=-1 --httpPort=8888 > /data/jenkins/jenkins.log &
#自定义端口为8888
--ajp13Port=-1 --httpPort=8888
[root@nmhs-pp-mw049181 ~]# ll /data/jenkins/

4.修改jenkins插件下载为国内源

[root@nmhs-pp-mw049181 ~]$ kill $(ps -ef | grep jenkins | grep -v grep | awk '{print $2}')
[root@nmhs-pp-mw049181 ~]$ sed -i 's/http:\/\/www.google.com/https:\/\/www.baidu.com/g' default.json
[root@nmhs-pp-mw049181 ~]$ sed -i 's/https:\/\/updates.jenkins.io\/download/https:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins/g' default.json
#如果是内网环境只能做单项路由才能访问的话需要添加
https://www.baidu.com  #IP 110.242.68.66
https://mirrors.tuna.tsinghua.edu.cn   #IP 101.6.8.193
的出口ip路由
[root@nmhs-pp-mw049181 ~]$ route add -net 110.242.68.66 netmask 255.255.255.255 gw 182.42.24.65
[root@nmhs-pp-mw049181 ~]$ route add -net 101.6.8.193 netmask 255.255.255.255 gw 182.42.24.65
[root@nmhs-pp-mw049181 ~]$ cat /etc/hosts
#jenkins国内源插件

101.6.8.193 mirrors.tuna.tsinghua.edu.cn
[root@nmhs-pp-mw049181 ~]$ nohup java -jar /data/jenkins/jenkins.war --ajp13Port=-1 --httpPort=8888 > /data/jenkins/jenkins.log &
