1、下载jenkins

• curl -O ：下载并以不同的文件名保存
• um的repo中默认没有Jenkins，需要先将Jenkins存储库添加到yum repos，执行下面的命令：
• rpm安装

curl -o /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo 

2、添加key

rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key

3、安装Jenkins

• 下载指定版本的rpm文件，进行rpm进行安装

# 在线安装
yum install -y jenkins

# 或 离线rpm安装
rpm -ivh jenkins-2.156-1.1.noarch.rpm

4、启动jenkins

systemctl jenkins start
systemctl start jenkins

5 、停用jenkins

systemctl jenkins stop
systemctl stop jenkins

6、重启jenkins

systemctl jenkins restart
systemctl restart jenkins

7、开机启动

systemctl enable jenkins

8、安装默认的目录

/usr/lib/jenkins/jenkins.war    WAR包 
/etc/sysconfig/jenkins          配置文件
/var/lib/jenkins/               默认的JENKINS_HOME目录
/var/log/jenkins/jenkins.log    

9、修改sysconfig的Jenkins文件

• JENKINS_USER访问用户，默认为Jenkins，把它改成root

vim /etc/sysconfig/jenkins
-----------------------------------------------------------------------
# 指定目录
JENKINS_HOME="/home/jenkins"

# 访问用户，默认为Jenkins，把它改成root
JENKINS_USER="root"

# 修改端口
JENKINS_PORT="8080"

10、给指定root用户进行授权

chown -R root:root /var/lib/jenkins
chown -R root:root /var/cache/jenkins
chown -R root:root /var/log/jenkins

11、创建jenkins目录

• JENKINS_HOME directory does not exist: /home/jenkins

mkdir /home/jenkins

12. 修改jenkins的配置文件

• whereis java 找到jdk安装目录 找到candidates="在它到后面添加jdk安装的目录,然后vi保存退出

vi /etc/init.d/jenkins
