一、概述

二、安装

1.安装

wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo
rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.key
yum install -y jenkins

或者下载rpm包来安装：

wget https://pkg.jenkins.io/redhat/jenkins-2.76-1.1.noarch.rpm
rpm -i jenkins-2.76-1.1.noarch.rpm

2.jenkins配置文件：

/etc/sysconfig/jenkins：

还有一个是/etc/init.d/jenkins，这里配置的是JDK路径，准确来说是java命令所在路径，
如果JDK重装过，启动Jenkins报错"Failed to start LSB: Jenkins Automation Server."，
需要重新配置JDK。

3.启动jenkins，访问ip:8080，在配置插件的时候出现错误：

查看/var/jenkins/log：

注意Failed to update the default Update Site 'default'：连接默认的站点超时。

看一下/var/lib/jenkins/hudson.model.UpdateCenter.xml：

把这个url换成下面的清华大学镜像地址，上面是已经换过的。建议换之前备份文件。

jenkins插件清华大学镜像地址：
https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json

4.jenkins目录：（引用自https://blog.youkuaiyun.com/miss1181248983/article/details/82840006）

ll /var/lib/jenkins
jobs		浏览器上面创建的任务都会存放在这里
logs		存放jenkins相关的日志
nodes		多节点时用到
plugins		插件所在目录
secrets		密码秘钥所在目录				#jobs和plugins目录比较重要

jenkins存放数据不依靠数据库，所以在移植时只需要拷贝整个程序主目录即可。

三、配置

安装git：

yum -y install git #安装git

安装maven：https://blog.youkuaiyun.com/Ivorybeach/article/details/100866463

Global Tool Configuration配置JDK，Maven，Git：

Configure System邮箱配置：

163和qq的邮箱服务都需要手机验证，我这里配不了，暂略。

Configure System配置SSH：

首先生成密钥，不配密码，然后复制公钥到待部署服务器：

ssh-keygen -t rsa    #生成密钥
ssh-copy-id -p 22022 -i /root/.ssh/id_rsa.pub root@ip #复制公钥，注意待部署服务器的port:22022

SSH Server配置：

-------------------------------------------上面是正确操作，以下是过程中出现的错误-----------------------------------------

在Jenkins上TestConfiguration失败后查看日志：

9月 16 09:58:52 localhost.localdomain sshd[1859]: Disconnected from 192.168.43.208 port 46516 [preauth]

百度一下上面的错误，Address 192.168.43.208 maps to localhost.localdomain, but this does not map back to the address - POSSIBLE BREAK，这个是说ip可以连到主机名，但是主机名对不上ip，也就是Ping主机名Ping不到192.168.43.208，这在SSH是不允许的，所以会报错。解决的话，一是就这个思路去解决，二是修改/etc/ssh/ssh_config和/etc/ssh/sshd_config中的GSSAPIAuthentication no，将no改为yes，这样ssh就不会验证ip和主机名必须对应了。
