hostnamectl set-hostname user1
bash

#  安装git
yum install -y git

# 克隆开源项目
 mkdir /test
 cd /test/
 git clone https://gitee.com/newrain001/easy-springmvc-maven.git

1.1.2服务器gitlab

# 配置主机名
hostnamectl set-hostname gitlab
bash

# 安装依赖
yum -y install vim gcc gcc-c++ wget net-tools lrzsz iotop lsof iotop bash-completion
yum -y install curl policycoreutils openssh-server openssh-clients postfix
yum -y install policycoreutils openssh-server openssh-clients postfix


# 下载gitlib

wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-13.1.4-ce.0.el7.x86_64.rpm --no-check-certificate
yum -y localinstall gitlab-ce-13.1.4-ce.0.el7.x86_64.rpm

# 编辑配置文件 改个默认端口 （82）
vim /etc/gitlab/gitlab.rb
    external_url 'http://192.168.11.103:82'
    nginx['listen_port'] = 82

# 重新加载配置文件-重启gitlab

                echo 'Hello World'
            }
        }
    }
}

node {
    def mvnHome
    stage('Preparation') { // for display purposes
        // Get some code from a GitHub repository
        git 'https://github.com/jglick/simple-maven-project-with-tests.git'
        // Get the Maven tool.
        // ** NOTE: This 'M3' Maven tool must be configured
        // **       in the global configuration.
        mvnHome = tool 'M3'
    }
    stage('Build') {
        // Run the maven build
        withEnv(["MVN_HOME=$mvnHome"]) {
            if (isUnix()) {
                sh '"$MVN_HOME/bin/mvn" -Dmaven.test.failure.ignore clean package'
            } else {
                bat(/"%MVN_HOME%\bin\mvn" -Dmaven.test.failure.ignore clean package/)
            }
        }
    }
    stage('Results') {
