tomcat任务部署

tomcat项目部署

主机	IP	需求
web-1	192.168.78.144	tomcat+jenkins
web-2	192.168.78.145	tomcat

在RHEL-1主机上部署的jenkins将项目打包传输到RHEL-2主机上并可以实现网页效果

拉取代码

pipeline {
    agent any 
    stages {
        stage("pull code"){
            steps {
                git 'https://github.com/chendao2015/tomcat-java-demo.git'
            }
            
        }  
    }
}

应用并保存

完成后的任务保存路径

RHEL-1主机上查看

[root@localhost ~]# cd .jenkins/workspace/test/
[root@localhost test]# ls
db  Dockerfile  LICENSE  pom.xml  README.md  src
[root@localhost test]# 

安装maven打包工具

[root@localhost ~]# yum install maven -y

编写打包脚本

pipeline {
    agent any 
    stages {
        stage("pull code"){
            steps {
                git 'https://github.com/chendao2015/tomcat-java-demo.git'
            }
        }    
        stage("make pkg"){
            steps {
                sh """
                    mvn clean package -Dmaven.test.skip=true
                """
            }
        }  
    }
}

完成打包

//可以看到打包后新生成的target目录
[root@localhost ~]# cd .jenkins/workspace/test/
[root@localhost test]# cd target/
[root@localhost target]# ls
classes            ly-simple-tomcat-0.0.1-SNAPSHOT      maven-archiver
generated-sources  ly-simple-tomcat-0.0.1-SNAPSHOT.war  maven-status

完善脚本

pipeline {
    agent any 
    stages {
        stage("pull code"){
            steps {
                git 'https://github.com/chendao2015/tomcat-java-demo.git'
            }
        }    
        stage("make pkg"){
            steps {
                sh """
                    mvn clean package -Dmaven.test.skip=true
                """
            }
        } 
        stage("publish"){
            steps {
                sh """
                    cd /root/.jenkins/workspace/test/target/
                   scp ly-simple-tomcat-0.0.1-SNAPSHOT.war   root@192.168.220.30:/usr/local/tomcat/webapps/
                   ssh root@192.168.78.145 '/usr/local/tomcat/bin/catalina.sh stop && /usr//local/tomcat/bin/catalina.sh start'
                   """
            }
        }
    }
}
