[【原文链接】基于CentOS7系统虚拟机部署Jenkins环境](http://devops-dev.com/article/297)

# 一、安装Jenkins
（1）首先确保已经安装jdk，如未安装，请参考 [Java----CentOS7系统安装jdk1.8](http://devops-dev.com/article/296) 先安装jdk

（2）配置Jenkins源

```bash
sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
```
（3）安装Jenkins

```bash
yum install epel-release
yum install java-11-openjdk-devel
yum install jenkins
```
（4）配置Jenkins端口号

```bash
vi /etc/sysconfig/jenkins

#监听端口
JENKINS_PORT="10003"
```
（5）配置用户

```bash
vi /etc/sysconfig/jenkins

#修改配置
$JENKINS_USER="root"
```
（6）修改目录权限

```bash
chown -R root:root /var/lib/jenkins
chown -R root:root /var/cache/jenkins
chown -R root:root /var/log/jenkins
```
（7）启动Jenkins

```bash
systemctl start jenkins
```
（8）网页打开Jenkins，如：在网页打开，如 http://192.168.1.210:10003/ 
如下，根据页面提示找到密码并填入

```bash
[root@localhost ~]# cat /var/lib/jenkins/secrets/initialAdminPassword
599ad742855948e0b8af280ad2e1f09f
```

# 二、卸载Jenkins
（1）停止服务
```bash
systemctl stop jenkins
```
（2）删除文件
```bash
rm -rf /etc/sysconfig/jenkins.rpmsave
rm -rf /var/cache/jenkins/
rm -rf /var/lib/jenkins/
rm -rf /var/log/jenkins
rm -rf /usr/lib/jenkins
```
