搭建jenkins

下载安装

进入官网https://www.jenkins.io/download/下载最新linux-rpm包。

将下载得安装包在/usr/local安装（目录看自己意愿）

## 新建jenkins目录
mkdir /usr/local/jenkins

##  使用xftp工具将下载得npm包传输到当前目录

## 安装
rpm -ivh jenkins-2.238-1.1.noarch.rpm

配置jenkinsj

##	修改jenkin文件
vim /etc/sysconfig/jenkins

## 找到 JENKINS_PORT="8080"  并修改端口为0-65535中任意一个（不与其他端口冲突）
## 修改后
JENKINS_PORT="9000"

## 查找java目录
whereis java

## 输入whereis java 将/usr/local/java/jdk1.8.0_251/bin/java 拷贝（没有则安装jdk）
java: /usr/local/java /usr/local/java/jdk1.8.0_251/bin/java

## 配置jenkins java
vim /etc/init.d/jenkins
