篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Linux(centos6.5)下安装jenkins相关的知识,希望对你有一定的参考价值。

 

Jenkins 的前身是 Hudson 是一个可扩展的持续集成引擎。

通俗的来讲,jenkins就是一个可以实现自动化部署的一个插件,

对于我来说,也是应用在系统部署上。

废话不多说,直接进入我们的安装步骤吧

1.安装JDK,maven环境搭建

因为考虑到jenkins的实际应用场景,我们需要把这些基础环境先安装完成。

jdk安装比较简单不做赘述,maven环境借用了osc其他大侠的博客内容,

试了下安装成功。

maven官网下载安装包:http://maven.apache.org/download.cgi

自己根据需求下载版本,这里作者选择的是3.1.1版本。

1.把apache-maven-3.1.1-bin.tar.gz传到服务器上,

解压:

tar -zvxf apache-maven-3.1.1-bin.tar.gz

移至/usr/local下

1
mv apache-maven-3.1.1 /usr/local

配置环境变量

1
vi /etc/profile

在文件中加入

1
2
export MAVEN_HOME=/usr/local/apache-maven-3.1.1
export PATH=$PATH:$MAVEN_HOME/bin

重新编译文件

1
 source /etc/profile

验证maven是否安装成功

1
mvn --version

控制台显示如下:

Apache Maven 3.1.1 (0728685237757ffbf44136acec0402957f723d9a; 2013-09-17 23:22:22+0800)

Maven home: /usr/local/apache-maven-3.1.1

Java version: 1.7.0_25, vendor: Oracle Corporation

Java home: /usr/java/jdk1.7.0_25/jre

Default locale: zh_CN, platform encoding: UTF-8

OS name: "linux", version: "2.6.32-358.6.2.el6.x86_64", arch: "amd64", family: "unix"

表示安装成功。

2.安装jenkins

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

一条一条命令执行完成后,jenkins就安装完成了,非常简单吧。

然后需要配置下jenkins的端口,避免冲突。

1
vi /etc/sysconfig/jenkins

进入该文件,这个是jenkins的系统配置文件,

找到2处修改端口号:

JENKINS_PORT="8080"

JENKINS_AJP_PORT="8009"

默认是这样的,我们可以随意修改成自己需要的端口号,避免冲突(tomcat默认端口也是这样的)

这里作者修改成了:

JENKINS_PORT="8888"

JENKINS_AJP_PORT="8889"

接下来我们就可以尝试启动jenkins服务了。

1
service jenkins start

如果提示:Starting Jenkins                                           [确定]

则表示jenkins服务成功启动,你可以通过http://ip:端口号的方式直接访问jenkins了。

但是一般情况下会报错:

1
2
Starting Jenkins bash/usr/bin/java: 没有那个文件或目录
                                                           [失败]

如果出现该错误也不需要慌张,报这个错的原因是因为你的jdk配置错误,

执行命令:

1
java -version

java version "1.7.0_25"

Java(TM) SE Runtime Environment (build 1.7.0_25-b15)

Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)

我们可以看到jdk版本为1.7.0_25,复制该名称

1
vi /etc/init.d/jenkins

找到这段代码

candidates="
/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-1.7.0/bin/java
/usr/lib/jvm/jre-1.7.0/bin/java
/usr/lib/jvm/java-1.8.0/bin/java
/usr/lib/jvm/jre-1.8.0/bin/java
/usr/bin/java

我们会发现这里面没有叫1.7.0_25的文件目录

我们在这段代码后面加上

1
/usr/java/jdk1.7.0_25/bin/java

效果如下:

/usr/lib/jvm/jre-1.7.0/bin/java
/usr/lib/jvm/java-1.8.0/bin/java
/usr/lib/jvm/jre-1.8.0/bin/java
/usr/bin/java
/usr/java/jdk1.7.0_25/bin/java
"

保存退出。重新执行启动命令:

1
service jenkins start

是不是成功了呢?

停止命令:

1
service jenkins stop

重启命令:

1
service jenkins restart

成功启动后,我们就可以通过http://ip:端口号访问了。

到此,jenkins安装就OK了。呵呵

 

 

 

 

 

CentOS 上 Jenkins 安装

 

文章来源:http://www.cnblogs.com/zhangqingsh/archive/2013/03/19/2968998.html

 

1. 添加Jenkins的源(repository):

 

$ 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. 安装/检查JDK:

 

$ java --version

 

$ sudo yum install java-1.6.0-openjdk

 

3. 安装Jenkins:

 

$ sudo yum install jenkins

 

安装完成后,有如下相关目录:

 

(3.1)/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

 

(3.2) /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:

3.4)/var/log/jenkins/jenkins.log:Jenkins日志文件。

 

4. 启动Jenkins

 

$ sudo service jenkins start

 

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(如下):

 5. 登录Jenkins

 

如果没有特别配置端口,使用http://<ip address>:8080/登录Jenkins,并进行相关配置(插件安装、权限配置、View/Job创建等等)。
