# 安装Jenkins #

使用以下命令安装jenkins

> sudo wget -O /etc/yum.repos.d/jenkins.repo [http://pkg.jenkins-ci.org/redhat/jenkins.repo][http_pkg.jenkins-ci.org_redhat_jenkins.repo]  
> sudo rpm –import [https://jenkins-ci.org/redhat/jenkins-ci.org.key][https_jenkins-ci.org_redhat_jenkins-ci.org.key]  
> sudo yum install jenkins

# 启动、关闭jenkins服务 #

> sudo service jenkins start/stop/restart

# 防火墙设置 #

> firewall-cmd –zone=public –add-port=8080/tcp –permanent  
> firewall-cmd –zone=public –add-service=http –permanent  
> firewall-cmd –reload

# 访问jenkins #

在浏览器中输入[http://ip:8080][http_ip_8080]即可。  
如果安装完成并成功启动会有下图：

查看/var/lib/jenkins/secrets/initialAdminPassword这个文件，将密码复制出来，粘贴，继续进入配置页面，如下图：

这里可以根据自己需求选择推荐插件或者自己选择插件安装。

# 遇到的问题 #

1.  Starting jenkins (via systemctl): Job for jenkins.service failed. See ‘systemctl status jenkins.service’ and ‘journalctl -xn’ for details.  
    \[FAILED\]  
    这个问题出现的原因有两个：
    
    1.  jdk 未安装  
        使用java -version检测是否配置jdk  
        ![这里写图片描述][SouthEast 2]
    2.  jenkins配置文件中未正确配置jdk的路径  
        使用以下命令查看jenkins配置：vi /etc/init.d/jenkins  
        在该配置中找到jdk的配置，jenkins有一个默认的jdk配置，这个配置与个人的jdk配置可能不一样，只需要在该配置下增加自己的jdk配置即可。  
        如图：![这里写图片描述][SouthEast 3]
    3.  Starting jenkins (via systemctl): Warning: jenkins.service changed on disk. Run ‘systemctl daemon-reload’ to reload units.  
        错误图：![这里写图片描述][SouthEast 4]  
        使用以下命令解决：systemctl daemon-reload
