Linux环境安装Jenkins

安装环境：

　　CenOS 6.4

　　JDK_1.6.0_23

 

一、安装前检查环境

检查是否安装JDK:　java --version

 

二、安装Jenkins

1. 添加Jenkins的源（repository）

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

(rpm --import 签名文件;wget -O　保存文件)

2.下载Jenkins

wget http://ftp-chi.osuosl.org/pub/jenkins/redhat/jenkins-1.573-1.1.noarch.rpm

3.安装Jenkins

rpm -ivh jenkins-1.573-1.1.noarch.rpm

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：

## 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=""

（3.3）/var/lib/jenkins/：默认的JENKINS_HOME。目录结构如下：

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

 

4. 启动Jenkins

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)：

64 # Search usable Java. We do this because various reports indicated
65 # that /usr/bin/java may not always point to Java 1.5
66 # see http://www.nabble.com/guinea-pigs-wanted-----Hudson-RPM-for-RedHat-Linux-td25673707.html
67 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/local/jdk_1.6.0_23/bin/java

68 do
69 [ -x "$JENKINS_JAVA_CMD" ] && break
70 JENKINS_JAVA_CMD="$candidate"
71 done

 

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）。
