软件准备：
| jenkins-2.7.4-1.1.noarch.rpm java环境 |
安装jenkins：
| [root@localhost modules]# rpm -ih jenkins-2.7.4-1.1.noarch.rpm |
jenkins 常用命令：
| service jenkins start/stop/restart chkconfig jenkins on |
jenkins的目录结构：
| /usr/lib/jenkins/jenkins.war WAR包 /etc/sysconfig/jenkins 配置文件 /var/lib/jenkins/ 默认的JENKINS_HOME目录 /var/log/jenkins/jenkins.log Jenkins日志文件 |
启动jekins：
| [root@localhost jenkins]# service jenkins start
Starting Jenkins bash: /usr/bin/java: 没有那个文件或目录
[失败] |
出现此异常说明没有找到 java 目录下的 bin 目录，解压不了 jenkins.war 。
解决方案：
| [root@localhost bin]# vim /etc/init.d/jenkins # Search usable Java. We do this because various reports indicated
# that /usr/bin/java may not always point to Java >= 1.6
# see http://www.nabble.com/guinea-pigs-wanted-----Hudson-RPM-for-RedHat-Linux-td25673707.html

带色文字为我的 java 目录，脚本含义就是查找 java 目录，解压jenkins.war包。
修改jenkins端口：
| vim /etc/sysconfig/jenkins
JENKINS_PORT="8888" |
防火墙开启8888端口：
| [root@localhost modules]# vim /etc/sysconfig/iptables
# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.

再次启动jenkins：
| [root@localhost modules]# service jenkins start |
效果图：
出现此提示说明，启动成功！因为是第一次安装，所以得输入默认密码，默认密码在红框标注的位置。
查看默认密码将密码粘贴到文本框中：
| [root@localhost secrets]# cat /var/lib/jenkins/secrets/initialAdminPassword
