centos 安装jenkins

Jenkins是开源的Java编写的持续集成的工具，在Centos上可以通过yum命令行直接安装。

安装Java

看到当前系统java版本。

java -version
如果java不存在运行命令：

sudo yum install java
如果java不存在可以安装java,如果java存在可以升级java。

安装Jenkins

添加Jenkins源:

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

安装Jenkins:

yum install jenkins

启动Jenkins
输入命令启动Jenkins:

sudo service jenkins start
Starting Jenkins [ OK ]

在浏览器中输入：http://127.0.0.1:8080/ 就可以使用jenkins了,如果没有UI系统可以在其他的浏览器中输入http://<所在机器的ip>:8080/进入Jenkins界面。

sudo service jenkins stop

可以停止Jenkins服务。

相关配置

Jenkins安装目录：

cd /usr/lib/jenkins/
jenkins.war

可以查看jenkins默认的配置。这里介绍下三个比较重要的配置目录JENKINS_HOME ,JENKINS_USER ,JENKINS_PORT

#
# Directory where Jenkins store its configuration and working
# files (checkouts, build reports, artifacts, ...).
#
JENKINS_HOME="/var/lib/jenkins"

Jenkins储存文件的地址,Jenkins的插件，生成的文件都会放在这里。

## Type:        string
## Default:     "jenkins"
## ServiceRestart: jenkins
#
# Unix user account that runs the Jenkins daemon
# Be careful when you change this, as you need to update
# permissions of $JENKINS_HOME and /var/log/jenkins.
#
JENKINS_USER="jenkins"

Jenkins使用的用户，默认为jenkins

## Type:        integer(0:65535)
## Default:     8080
## ServiceRestart: jenkins
#
# Port Jenkins is listening on.
# Set to -1 to disable
#
JENKINS_PORT="8080"

Jenkins的端口，默认端口是8080。

启动配置文件

/etc/init.d/jenkins 文件
