centos 6.9 + JenKins 安装记录
环境：

[root@localhost ~]# cat /etc/issue

第一步：检查发现系统自带java环境

[root@localhost ~]# java -version
openjdk version "1.8.0_161"
OpenJDK Runtime Environment (build 1.8.0_161-b14)
OpenJDK 64-Bit Server VM (build 25.161-b14, mixed mode)

[root@localhost ~]# vi /etc/profile
添加以下内容 注意对应自己系统里的版本
JAVA_HOME=/usr/lib/jvm/jre-1.8.0-openjdk.x86_64
JRE_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.161-3.b14.el6_9.x86_64/jre
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME
export JAVA_HOME
export JRE_HOME
export PATH
[root@localhost ~]# source /etc/profile
[root@localhost ~]# echo $JAVA_HOME
/usr/lib/jvm/jre-1.8.0-openjdk.x86_64
[root@localhost ~]#

第三步：安装JenKins
1.下载源

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

2.yum安装

[root@localhost ~]# yum install jenkins

3.修改端口（可选默认端口为8080）

[root@localhost ~]# diff /etc/sysconfig/jenkins.bak /etc/sysconfig/jenkins
56c56
< JENKINS_PORT="8080"
---
> JENKINS_PORT="9000"

4.启动jenkins服务

[root@localhost ~]# service jenkins start
Starting Jenkins                                           [  OK  ]
[root@localhost ~]# ss -lntp|grep 9000
LISTEN     0      50                       :::9000                    :::*      users:(("java",1738,159))
