linux部署jenkins，支持jdk1.8

news2024/10/5 8:50:17

无废话，纯干活安装指令
本文前提条件需安装jdk8，安装参考：Linux配置jdk环境

下载资源

# 创建安装目录
mkdir -p /data/jenkins && cd /data/jenkins

# 下载jenkins的war包，v2.346.x支持jdk1.8，高于这个版本的最低都jdk11起步
wget http://mirrors.jenkins.io/war-stable/2.346.3/jenkins.war

快捷脚本

# 创建脚本
vim restart-jenkins.sh

#!/bin/sh
# Description: restart jenkins and kill old jenkins process
# Author: 954L
# Date: 2024-02-20

pid=$(pgrep -f jenkins.war)
if [ -n "$pid" ]; then
    kill $pid
    if [ $? -eq 0 ]; then
        echo "kill jenkins process success, wait ten second"
	sleep 3
    else
        echo "failed to kill jenkins process"
    fi
else
    echo "no jenkins process found"
fi

nohup java -jar jenkins.war --httpPort=9095 > console.log &
echo "start jenkins success\nprint jenkins logs on line"
tail -f console.log

9095：自定义jenkins的web端口
