在這裡記錄下安裝的步驟，方便以後進行檢視

首先，需要安裝好Java以及安裝好Git。

安裝Java

安裝Git

一行命令即可

yum install -y git

檢查Git

git --version

安裝Jenkins

先新增Jenkins源

sudo wget -O /etc/yum.repos.d/jenkins.repo http://jenkins-ci.org/redhat/jenkins.repo

然後

sudo rpm --import http://pkg.jenkins-ci.org/redhat/jenkins-ci.org.key

新增完成之後直接使用yum命令安裝Jenkins

yum install jenkins  

啟動Jenkins

使用命令啟動Jenkins

sudo service jenkins start

在瀏覽器中輸入：http://<伺服器ip>:8080/ 就可以進入Jenkins介面直接使用了

停止Jenkins

sudo service jenkins stop

相關配置

Jenkins安裝目錄

 /var/lib/jenkins/

Jenkins配置檔案目錄

/etc/sysconfig/jenkins

可以在這裡檢視Jenkins預設的配置

cat jenkins  

配置說明

這裡介紹下三個比較重要的配置：

• JENKINS_HOME
• JENKINS_USER
• JENKINS_PORT

JENKINS_HOME是Jenkins的主目錄，Jenkins工作的目錄都放在這裡,Jenkins儲存檔案的地址,Jenkins的外掛，生成的檔案都在這個目錄下

## Path:        Development/Jenkins
## Description: Jenkins Continuous Integration 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"

JENKINS_USER 是Jenkins的使用者，擁有$JENKINS_HOME和/var/log/jenkins的許可權

## 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"

JENKINS_PORT是Jenkins的埠，預設埠是8080

## Type:        integer(0:65535)  
## Default:     8080
## ServiceRestart: jenkins
#
# Port Jenkins is listening on.
# Set to -1 to disable
#
JENKINS_PORT="8080"
