war 包方式部署Jenkins

#安装一个Tomcat作为中间件
#需要Java1.8以上的JDK环境
[root@jenkins /]# java -version 
openjdk version "1.8.0_102"
OpenJDK Runtime Environment (build 1.8.0_102-b14)
OpenJDK 64-Bit Server VM (build 25.102-b14, mixed mode)
#部署Tomcat
[root@jenkins ~]# wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-7/v7.0.100/bin/apache-tomcat-7.0.100.tar.gz
[root@jenkins ~]# tar zxf apache-tomcat-7.0.100.tar.gz 
[root@jenkins ~]# mv apache-tomcat-7.0.100/ /usr/local/tomcat
[root@jenkins ~]# echo  'export CATALINA_HOME=/usr/local/tomcat' >> /etc/profile
[root@jenkins ~]# echo 'export PATH=$CATALINA_HOME/bin:$PATH' >> /etc/profile
[root@jenkins ~]# source /etc/profile
[root@jenkins /]# vim /usr/local/tomcat/conf/server.xml           # 修改tomcat端口号
<Connector port="8081" protocol="HTTP/1.1"
[root@jenkins ~]# startup.sh 
[root@jenkins ~]# netstat -anput | grep 8081
tcp6       0      0 :::8081                 :::*                    LISTEN      3006/java    
#当将Jenkins的war包放入中间件时，它会自动去进行部署，所以我们可以通过查看日志去看到安装状态
[root@jenkins /]# tail -f /usr/local/tomcat/logs/

[root@jenkins ~]# wget http://mirrors.jenkins.io/war-stable/latest/jenkins.war
[root@jenkins ~]# cp jenkins.war /usr/local/tomcat/webapps/            # 复制到tomcat项目目录中
#在自动部署过程中会出现一行管理员密码
[root@jenkins ~]# cat /root/.jenkins/secrets/initialAdminPassword           # 也可通过查看此文件来确定密码

#安装完毕Jenkins后会在root目录下建立一个隐藏目录
[root@jenkins ~]# sed -i 's/http:\/\/www.google.com\//http:\/\/www.baidu.com\//g' /root/.jenkins/updates/default.json 
[root@jenkins ~]# sed -i 's#http://updates.jenkins-ci.org/download/#https://mirrors.tuna.tsinghua.edu.cn/jenkins/#g' /root/.jenkins/updates/default.json 
[root@jenkins ~]# shutdown.sh
[root@jenkins ~]# startup.sh 
[root@jenkins ~]# tail -f /usr/local/tomcat/logs/catalina.out           # 查看运行状况
#再次访问Jenkins网页，重新输入密码安装插件
