centos7上搭建jenkins环境

1、安装环境说明：

系统：

[root@localhost bin]# cat /etc/centos-release

CentOS Linux release 7.1.1503 (Core) 

[root@localhost bin]# uname -a

Linux localhost.localdomain 3.10.0-229.14.1.el7.x86_64 #1 SMP Tue Sep 15 15:05:51 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

2、安装步骤

（1）安装jdk

java -version没有输出，则说明未安装jdk，下面以jdk1.7的为例

yum -y install java-1.7.0-openjdk

安装完后，查看jdk的版本，确认是否安装成功

       [root@localhost install]# java -version

java version "1.7.0_91"

OpenJDK Runtime Environment (rhel-2.6.2.1.el7_1-x86_64 u91-b00)

OpenJDK 64-Bit Server VM (build 24.91-b01, mixed mode)

 （2）安装apache-tomcat

      下载apache-tomcat

wget http://mirrors.hust.edu.cn/apache/tomcat/tomcat-7/v7.0.65/bin/apache-tomcat-7.0.65.tar.gz
解压一下

        tar -xvf  apache-tomcat-7.0.65.tar.gz

拷贝到/usr/local目录下

        mv apache-tomcat-7.0.65 /usr/local/tomcat

运行tomcat

        cd /usr/local/tomcat/bin && ./start.sh

        打开浏览器输入http://xxxx:8080，看到apache的欢迎界面，则tomcat部署好了，如果没有看见，估计是8080端口未允许访问，则执行以下命令：

       iptables -I INPUT -p tcp --dport 8080 -j ACCEPT

  （3）安装apache-maven

下载apache-maven

        wget http://ftp.meisei-u.ac.jp/mirror/apache/dist/maven/maven-3/3.3.3/binaries/apache-maven-3.3.3-bin.tar.gz
解压一下

tar -xvf  apache-maven-3.3.3-bin.tar.gz

       拷贝到/usr/local目录下

       mv apache-maven-3.3.3-bin   /usr/local/maven

  (4)设置环境变量

编辑/etc/profile文件，新增和导出以下变量：

      JAVA_HOME=/usr/lib/jvm/jre-1.7.0-openjdk-1.7.0.91-2.6.2.1.el7_1.x86_64

      JRE_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.91-2.6.2.1.el7_1.x86_64/jre

      TOMCAT_HOME=/usr/local/tomcat

      MAVEN_HOME=/usr/local/maven

      export MAVEN_HOME

      export JAVA_HOME

      export JRE_HOME

      export PATH

      export PATH=${PATH}:${MAVEN_HOME}/bin

      export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL

      使环境变量生效

      source /etc/profile

      执行mvn -v，检查一下apache-maven是否安装成功

    [root@localhost bin]# mvn -v

Apache Maven 3.3.3 (7994120775791599e205a5524ec3e0dfe41d4a06; 2015-04-22T07:57:37-04:00)

Maven home: /usr/local/maven

Java version: 1.7.0_91, vendor: Oracle Corporation

Java home: /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.91-2.6.2.1.el7_1.x86_64/jre

Default locale: en_US, platform encoding: UTF-8

OS name: "linux", version: "3.10.0-229.14.1.el7.x86_64", arch: "amd64", family: "unix"

  （5）安装jenkins

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

         cp /usr/lib/jenkins/jenkins.war  /usr/local/tomcat/webapps

   然后重启tomcat服务

       cd /usr/local/tomcat/bin

       ./shutdown.sh && ./startup.sh

      最后在浏览器上输入http://xxxx:8080/jenkins/，
