tomcat上部署jenkins

//安装jdk

[root@node1 ~]# yum -y install java-17-openjdk

//下载9.0版本，10的版本部署有bug，无法实现
[root@node1 ~]# wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-9/v9.0.67/bin/apache-tomcat-9.0.67.tar.gz


//解压tomcat，并部署安装
[root@node1 ~]# tar -xzf apache-tomcat-9.0.67.tar.gz -C /usr/local/
[root@node1 ~]# cd /usr/local/
[root@node1 local]# ln -s apache-tomcat-9.0.67/ tomcat
[root@node1 local]# ls
apache-tomcat-9.0.67  bin  etc  games  include  lib  lib64  libexec  sbin  share  src  tomcat


//启动tomcat，测试能否访问tomcat首页
[root@node1 ~]# /usr/local/tomcat/bin/startup.sh 
[root@node1 ~]# ss -anlt | grep 8080
LISTEN 0      100                     *:8080            *:*         

//下载jenkins到/usr/local/tomcat/webapps/目录下
[root@node1 ~]# cd /usr/local/tomcat/webapps/


//下载下来后会自动解压
[root@node1 webapps]# wget http://mirrors.jenkins.io/war-stable/2.346.3/jenkins.war
[root@node1 webapps]# ls
ROOT  docs  examples  host-manager  jenkins  jenkins.war  manager

//启动服务
[root@node1 webapps]# cd ..
[root@node1 tomcat]# bin/catalina.sh stop
[root@node1 tomcat]# bin/catalina.sh start

[root@localhost tomcat]# cat /root/.jenkins/secrets/initialAdminPassword
4f193a8fbd934ca6a578f474a0d1b403

/先在node1主机上生成一个密钥，传给node2主机

[root@node1 ~]# ssh-keygen
[root@node1 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub root@192.168.111.142

在node2上部署tomcat

[root@node2 ~]# yum -y install java-11-openjdk
[root@node2 ~]# wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-9/v9.0.67/bin/apache-tomcat-9.0.67.tar.gz
[root@node2 ~]# tar -xzf apache-tomcat-9.0.67.tar.gz -C /usr/local/
[root@node2 ~]# cd /usr/local/
[root@node2 local]# ln -s apache-tomcat-9.0.67/ tomcat
[root@node2 local]# ls
apache-tomcat-9.0.67  bin  etc  games  include  lib  lib64  libexec  sbin  share  src  tomcat

node1中安装git和maven

[root@node1 ~]# yum -y install git maven 

添加git下载信息 http://github.com/lizhenliang/tomcat-java-demo.git

添加ip

写脚本

pipeline {
    agent any
 
    stages {
        stage('pull code') {
            steps {
                git '${git_url}'
            }
        }
        stage('package') { 
            steps { 
                sh """ 
	            mvn clean
	            mvn package
	            """
	        }
        }

                """
