一、部署jenkins

1、设置jenkins家目录环境

[root@VM_8_24_centos ~]# yum -y install java
[root@VM_8_24_centos builds]# java -version
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)

2、安装jenkins

[root@VM_8_24_centos ~]# wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat-stable/jenkins.repo
[root@VM_8_24_centos ~]# rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.key
[root@VM_8_24_centos ~]# yum -y install jenkins

Complete!

3、修改jenkins家目录位置
默认是/var/lib/jenkins，修改后启动服务，如果之前启动过，这边重启服务会重新安装插件等到新目录

[root@VM_8_24_centos ~]# mkdir /data1/jenkins/
[root@VM_8_24_centos ~]# chown jenkins:jenkins /data1/jenkins/
[root@VM_8_24_centos ~]# source /etc/profile
[root@VM_8_24_centos ~]# echo $JENKINS_HOME
/data1/jenkins
[root@VM_8_24_centos ~]# grep JENKINS_HOME /etc/sysconfig/jenkins 
JENKINS_HOME="/data1/jenkins"
# permissions of $JENKINS_HOME and /var/log/jenkins.
# $JENKINS_HOME location. Do not enable this, "true", unless

4、启动jenkins服务

[root@VM_8_24_centos ~]# systemctl start jenkins
[root@VM_8_24_centos ~]# systemctl status jenkins
● jenkins.service - LSB: Jenkins Automation Server
   Loaded: loaded (/etc/rc.d/init.d/jenkins; bad; vendor preset: disabled)

二、初始化jenkins环境

1、浏览器打开ip:8080端口输入密码

2、选择安装插件

3、创建初始管理账号

4、设置jenkins url默认http://ip:8080

5、开始使用jenkins

6、jenkins控制台界面，主要配置都在系统管理中

三、配置ldap

1、系统配置-全局安全配置-Security Realm-选择LDAP-Advanced Service Configtion

2、Security Realm-Authorization-Add user or group设置权限

3、域账号登陆
