Centos7安装Jenkins脚本一键部署

公司原先Jenkins二进制安装，自己闲来无事在测试主机优化了一下，一键部署，jenkins2.426版本+jdk11版本

#!/bin/bash

jenkins_file="jenkins-2.426.3-1.1.noarch.rpm"

# 更新软件包列表
echo "更新软件包列表..."
sudo yum update

# 检查Java是否已安装
if java -version &>/dev/null; then
    echo "Java已安装，跳过此步骤。"
else
    echo "安装Java 11..."
    sudo yum install  java-11-openjdk
fi



if  rpm -aq |grep jenkins; then
    echo "Jenkins已安装，跳过安装步骤。"
else
    echo "安装Jenkins..."
    sudo rpm -ivh $jenkins_file
	chown -R jenkins:jenkins /usr/bin/jenkins
    

fi

# 启动并启用Jenkins服务
if systemctl is-active --quiet jenkins; then
    echo "Jenkins服务正在运行，跳过启动。"
else
    echo "启动Jenkins服务..."
    sudo systemctl start jenkins
fi

if systemctl is-enabled --quiet jenkins; then
    echo "Jenkins服务已设置为开机启动。"
else
    echo "设置Jenkins服务为开机启动..."
    sudo systemctl enable jenkins
fi

# 输出Jenkins的初始管理员密码
if [ -f /var/lib/jenkins/secrets/initialAdminPassword ]; then
    echo "Jenkins安装完成！"
    echo "初始管理员密码如下："
    sudo cat /var/lib/jenkins/secrets/initialAdminPassword
else
    echo "Jenkins尚未成功安装或未能生成初始管理员密码。"
fi

测试结果如下：

安装成功
