1、將安裝包jenkins-2.156-1.1.noarch.rpm包上傳到linux伺服器
2、執行命令：rpm -ih jenkins-2.156-1.1.noarch.rpm
[[email protected] ~]# rpm -ih jenkins-2.156-1.1.noarch.rpm

3、安裝後檢視各目錄如下
WAR： /usr/lib/jenkins/jenkins.war
配置：/etc/sysconfig/jenkins
日誌：/var/log/jenkins/jenkins.log
4、啟動jenkins
service jenkins start
啟動如出現錯誤：Starting jenkins (via systemctl): Job for jenkins.service failed because the control process exited with error code. See "systemctl status jenkins.service" and "journalctl -xe" for details.
需要檢查java安裝路徑在/etc/init.d/Jenkins中是否配置正確，如不正確，加入java安裝路徑
5、訪問jenkins
http://ip:8080
第一次訪問的密碼從以下路徑中獲取
cat /var/lib/jenkins/secrets/initialAdminPassword
另：如果需要修改使用者和埠，可修改如下配置：
vi /etc/sysconfig/jenkins
JENKINS_USER="admin"
JENKINS_PORT="8001"
然後重啟服務：
service jenkins stop
service jenkins start
或者是：
systemctl restart jenkins.service
