Linux环境下Jenkins简单搭建步骤

简介

Jenkins是一个开源软件项目，旨在提供一个开放易用的软件平台，使软件的持续集成变成可能。这是一款基于Java开发的工具。

种种原因，最近刚开始接触，决定研究一下。Jenkins的搭建方法不止一种，一下就是个人总结的其中一种，文章内容比较浅显，不足之处，欢迎指正。

JDK下载地址应该不用说了，相信你肯定能搜到。

Maven下载地址 http://maven.apache.org/download.cgi

安装软件如下：

jdk-8u131-linux-x64.tar.gz

apache-maven-3.5.0-bin.tar.gz

环境：

[[email protected] ]# uname -a

Linux node02.cn 2.6.32-642.el6.x86_64 # 17:27:01 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

[[email protected] ~]# setenforce 0

一、配置JDK

[[email protected] jdk]# pwd
/data/jdk
[[email protected] jdk]# ls
jdk-8u131-linux-x64.tar.gz

解压JDK安装包：

[[email protected] jdk]# tar zxvf jdk-8u131-linux-x64.tar.gz
[[email protected] jdk]# ls
jdk1.8.0_131 jdk-8u131-linux-x64.tar.gz
[[email protected] jdk]# cd jdk1.8.0_131/

[[email protected] jdk1.8.0_131]# pwd
/data/jdk/jdk1.8.0_131

[[email protected] jdk1.8.0_131]# ls
bin db javafx-src.zip lib man release THIRDPARTYLICENSEREADME-JAVAFX.txt
COPYRIGHT include jre LICENSE README.html src.zip THIRDPARTYLICENSEREADME.txt
[[email protected] jdk1.8.0_131]#

创建环境变量文件：（为了方便维护，在下创建某个应用的环境变量文件）

[[email protected] jdk1.8.0_131]# vim /etc/profile.d/java-jdk.sh
[[email protected] jdk1.8.0_131]# cat !$
cat /etc/profile.d/java-jdk.sh
export JAVA_HOME=/data/jdk/jdk1.8.0_131
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

存退出后，用source生效一下：

[[email protected] jdk1.8.0_131]# source !$
source /etc/profile.d/java-jdk.sh

测试JAVA环境：

[[email protected] jdk1.8.0_131]# java -version
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)
[[email protected] jdk1.8.0_131]#

二、配置Maven

[[email protected] maven]# pwd
/data/maven
[[email protected] maven]# ls
apache-maven-3.5.0-bin.tar.gz

解压：

[[email protected] maven]# tar zxvf apache-maven-3.5.0-bin.tar.gz ^C
[[email protected] maven]# ls
apache-maven-3.5.0 apache-maven-3.5.0-bin.tar.gz
[[email protected] maven]# cd apache-maven-3.5.0
[[email protected] apache-maven-3.5.0]# ls
bin boot conf lib LICENSE NOTICE README.txt

配置并生效环境变量：

[[email protected] apache-maven-3.5.0]# vim /etc/profile.d/maven.sh
[[email protected] apache-maven-3.5.0]# source !$
source /etc/profile.d/maven.sh
[[email protected] apache-maven-3.5.0]# cat /etc/profile.d/maven.sh
export MAVEN_HOME=/data/maven/apache-maven-3.5.0
export PATH=$MAVEN_HOME/bin:$PATH
[[email protected] apache-maven-3.5.0]#

测试：

[[email protected] apache-maven-3.5.0]# mvn -v
Apache Maven 3.5.0 (ff8f5e7444045639af65f6095c62210b5713f426; 2017-04-04T03:39:06+08:00)
Maven home: /data/maven/apache-maven-3.5.0
Java version: 1.8.0_131, vendor: Oracle Corporation
Java home: /data/jdk/jdk1.8.0_131/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "2.6.32-642.el6.x86_64", arch: "amd64", family: "unix"
[[email protected] apache-maven-3.5.0]#

配置成功！

三、安装Jenkins：

[[email protected] ~]# wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/RedHat/jenkins.repo
[[email protected] ~]# rpm --import http://pkg.jenkins-ci.org/redhat/jenkins-ci.org.key
[[email protected] ~]# yum clean all
[[email protected] ~]# yum install jenkins
[[email protected] ~]#

配置Jenkins:
修改Jenkins的配置文件

[[email protected] ~]# vim /etc/sysconfig/jenkins #默认端口是8080
53 # Port Jenkins is listening on.
54 # Set to -1 to disable
55 #
56 JENKINS_PORT="8080"
57
58 ## Type: string
59 ## Default: ""
60 ## ServiceRestart: jenkins
61 #
62 # IP address Jenkins listens on for HTTP requests.
63 # Default is all interfaces (0.0.0.0).
64 #
65 JENKINS_LISTEN_ADDRESS=""
.

修改Jenkins的服务脚本

[[email protected] ~]# vim /etc/init.d/jenkins
.
64 # Search usable Java as /usr/bin/java might not point to minimal version required by Jenkins.
65 # see http://www.nabble.com/guinea-pigs-wanted-----Hudson-RPM-for-RedHat-Linux-td25673707.html
66 candidates="
67 /etc/alternatives/java
68 /usr/lib/jvm/java-1.8.0/bin/java
69 /usr/lib/jvm/jre-1.8.0/bin/java
70 /usr/lib/jvm/java-1.7.0/bin/java
71 /usr/lib/jvm/jre-1.7.0/bin/java
72 /usr/bin/java
73 /data/jdk/jdk1.8.0_131/bin/java #添加内容--指定你的JAVA所在路径
74 "
75 for candidate in $candidates
76 do
77 [ -x "$JENKINS_JAVA_CMD" ] && break
78 JENKINS_JAVA_CMD="$candidate"
.
