系统版本为CentOS版本为6.8，使用Windows的应该比较简单，如果使用Mac的可以看我的这篇文章：配置jenkins打包Android程序的环境-Mac篇
1.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
2.检查安装JDK（JDK 7 以上版本才支持Jenkins）
$ java --version
$ sudo yum install java-1.8.0
如果以前的java版本低或者想用新的jdk，可以把他们卸载
yum remove java-1.6.0-openjdk
yum remove java-1.7.0-openjdk
设置jdk全局环境变量
我们可以用如下命令来轻松设置你安装JDK的环境变量:
export JAVA_HOME=/usr/java/jdk1.8.0_25/
export PATH=$PATH:$JAVA_HOME
现在，让我们用下面的命令来查看JDK的环境变量:
echo $JAVA_HOME
输出结果如下：
/usr/java/jdk1.8.0_25/
或者
echo $PATH
输出结果如下：
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/usr/java/jdk1.8.0_25/
3.安装Jenkins
$ sudo yum install jenkins
如果发现找不到jenkins包，需要更新一下yum源，
$ yum -y update
还是没有，则在yum源中搜索一下：
$ yum search jenkins
$ sudo yum install jenkins
如果还是没有搜索到Jenkins，则添加Jenkins源
$ sudo wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo
$ sudo rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.key
$ sudo yum install jenkins
如果出现没有授权key的提示导致无法安装，可以使用如下语句：
$ yum install jenkins --nogpgcheck
4.配置Jenkins目录
安装完成后，会有一下目录
- /usr/lib/jenkins/：jenkins安装目录，WAR包会放在这里。
$ cd /usr/lib/jenkins
$ ll -rw-r--r-- 1 root root 52891723 Feb 27 00:13 jenkins.war
- /etc/sysconfig/jenkins：
jenkins配置文件，“端口”，“JENKINS_HOME”等都可以在这里配置。内容如下，其中Jenkins的端口号和tomcat是一致的都是8080，有冲突的话可以自行更改端口号：
## Path: Development/Jenkins
## Description: Configuration for the Jenkins continuous build server
## Type: string
## Default: "/var/lib/jenkins"
## ServiceRestart: jenkins
#
# Directory where Jenkins store its configuration and working
# files (checkouts, build reports, artifacts, ...).
#
JENKINS_HOME="/var/lib/jenkins"
## Type: string
## Default: ""
## ServiceRestart: jenkins
#
# Java executable to run Jenkins
# When left empty, we'll try to find the suitable Java.
#
JENKINS_JAVA_CMD=""
## 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"
## Type: string
## Default: "-Djava.awt.headless=true"
## ServiceRestart: jenkins
#
# Options to pass to java when running Jenkins.
#
JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true"
## Type: integer(0:65535)
## Default: 8080
## ServiceRestart: jenkins
#
# Port Jenkins is listening on.
# Set to -1 to disable
#
JENKINS_PORT="8080"
## Type: integer(0:65535)
## Default: 8009
## ServiceRestart: jenkins
#
# Ajp13 Port Jenkins is listening on.
# Set to -1 to disable
#
JENKINS_AJP_PORT="8009"
## Type: integer(1:9)
## Default: 5
## ServiceRestart: jenkins
#
# Debug level for logs -- the higher the value, the more verbose.
# 5 is INFO.
#
JENKINS_DEBUG_LEVEL="5"
## Type: yesno
## Default: no
## ServiceRestart: jenkins
#
# Whether to enable access logging or not.
#
JENKINS_ENABLE_ACCESS_LOG="no"
## Type: integer
## Default: 100
## ServiceRestart: jenkins
#
# Maximum number of HTTP worker threads.
#
JENKINS_HANDLER_MAX="100"
## Type: integer
## Default: 20
## ServiceRestart: jenkins
#
# Maximum number of idle HTTP worker threads.
#
JENKINS_HANDLER_IDLE="20"
## Type: string
## Default: ""
## ServiceRestart: jenkins
#
# Pass arbitrary arguments to Jenkins.
# Full option list: java -jar jenkins.war --help
#
JENKINS_ARGS=""
- /var/lib/jenkins/：默认的JENKINS_HOME。目录结构如下：
$ cd /var/lib/jenkins/
$ ls -lst
total 216

- /var/log/jenkins/jenkins.log：Jenkins日志文件。
启动，重启，关闭Jenkins：
$ sudo service jenkins start
$ sudo service jenkins restart
$ sudo service jenkins shutdown
此时，有可能出现有可能出现错误：“Starting Jenkins -bash: /usr/bin/java: No such file or directory”。表示找不到Jenkins找不到java。
这时就需要“vi /etc/init.d/jenkins”，把java路径加上：
$ Search usable Java. We do this because various reports indicated
$ that /usr/bin/java may not always point to Java 1.5
$ see http://www.nabble.com/guinea-pigs-wanted-----Hudson-RPM-for-RedHat-Linux-td25673707.html
for candidate in /etc/alternatives/java /usr/lib/jvm/java-1.6.0/bin/java /usr/lib/jvm/jre-1.6.0/bin/java /usr/lib/jvm/java-1 .5.0/bin/java /usr/lib/jvm/jre-1.5.0/bin/java /usr/bin/java /usr/j2sdk/bin/java
do
[ -x "$JENKINS_JAVA_CMD" ] && break
JENKINS_JAVA_CMD="$candidate"
done
此时，可在浏览器中打开Jenkins页面(默认端口8080)：localhost:8080
- 修改Jenkins密码
Jenkins密码可能忘记的话，用一下语句可以重置
$ sudo passwd jenkins
5.配置Jenkins打包所需的其他软件环境
1.安装Gradle
- 在http://www.gradle.org/downloads页面，下载最新版的gradle软件包
- 解压gradle
$ cd /usr.local
$ sudo unzip ~/gradle-2.2.1-all.zip
- 设置运行时环境
$ sudo vi /etc/profile
在文件中增加GRADLE_HOME输出路径,并且修订PATH设置如下
export GRADLE_HOME=/usr/local/gradle-2.2.1
export PATH=${JAVA_HOME}/bin:${JRE_HOME}/bin:${GRADLE_HOME}/bin:${JAVA_HOME}:${PATH}
在PATH语句后面追加${GRADLE_HOME}/bin，让系统能够找到可执行文件的路径。
如果你不希望所有用户都使用这个配置，那么可以单独为自己的账号配置gradle环境，在自己账号的HOME目录下:
$ vi .bash_profile
进行类似的编辑即可。
- 保存退出后，为了让修改即时生效，执行:
$source /etc/profile
- 查看gradle的版本信息

$ gradle -version------------------------------------------------------------Gradle 2.2.1-----------------------------------------------------------

安装git
yum install git
至此，Jenkins为Android打包环境已经配置完成了。
