第一部分，安装Jenkins

1、首先在Jenkins repo yum源和Key

[root@jenkins ~]# wget http://pkg.jenkins.io/redhat-stable/jenkins.repo -O /etc/yum.repos.d/jenkins.repo
[root@jenkins ~]# rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key

2、安装Java

[root@jenkins ~]# yum install -y java
[root@jenkins ~]# java -version
openjdk version "1.8.0_191"
OpenJDK Runtime Environment (build 1.8.0_191-b12)
OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode)

3、安装最新版本Jenkins

[root@jenkins ~]# yum install jenkins -y

4、查看Jenkins配置文件，确保JENKINS_USER="jenkins"

[root@jenkins ~]# vim /etc/sysconfig/jenkins 
JENKINS_USER="jenkins"

5、创建Jenkins Home目录，并赋予Jenkins宿主

[root@jenkins ~]# mkdir /home/jenkins/
[root@jenkins ~]# chown jenkins:jenkins /home/jenkins

6、启动Jenkins服务

[root@jenkins ~]# systemctl start jenkins
[root@jenkins ~]# systemctl status jenkins
