在centos中安装jenkins
1）安装目录
pwd (/home/AAA)
2）检查java是否安装
[AAA@Centos_AAA jenkins]$ java -version
java version "1.6.0_22"
OpenJDK Runtime Environment (IcedTea6 1.10.4) (rhel-1.41.1.10.4.el6-x86_64)
OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode)
3）下载jenkins
mkdir -p jenkins/jenkins_home
mkdir -p jenkins/jenkins_node
cd jenkins
wget http://mirrors.jenkins-ci.org/war/latest/jenkins.war
4）启动jenkins
start_jenkins.sh
#!/bin/bash
JENKINS_ROOT=/home/AAA/jenkins
export JENKINS_HOME=$JENKINS_ROOT/jenkins_home
java -jar $JENKINS_ROOT/jenkins.war --httpPort=8000
chmod a+x start_jenkins.sh
nohup ./start_jenkins.sh > jenkins.log 2>&1 &
5）访问jenkins：
在浏览器中输入http://192.168.0.120:8000
6）配置jenkins：
configure golbal security->enable security
jenkins own user database + enable users to sign up + anyone can do anythings
then signup one user(jenkins_aaa：0) and login
7）安装jenkins plugins：
一开始在可选插件下面没有任何的插件可以安装，后来查了好多资料才发现在安装插件的页面的高级tab的右下角有个坑爹的按钮（立即获取）要点下。
