CentOS7安装Jenkins

一、准备工做

安装Java，确保Java版本在1.6及以上

[root@xa-dev-ci-1 ~]# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core) 
[root@xa-dev-ci-1 ~]# java -version
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)

二、安装jenkins

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

三、安装jenkins稳定版本

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

四、配置

Jenkins安装目录：/var/lib/jenkins/

Jenkins配置文件地址：/etc/sysconfig/jenkins，这就是Jenkins的配置文件，能够在这里查看Jenkins默认的配置。

这里介绍下三个比较重要的配置：

• JENKINS_HOME
• JENKINS_USER
• JENKINS_PORT

JENKINS_HOME是Jenkins的主目录，Jenkins工做的目录都放在这里,Jenkins储存文件的地址,Jenkins的插件，生成的文件都在这个目录下。

## 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的用户，拥有$JENKINS_HOME和/var/log/jenkins的权限。

## 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的端口，默认端口是8080。

## Type:        integer(0:65535)  
## Default:     8080
## ServiceRestart: jenkins
#
# Port Jenkins is listening on.
# Set to -1 to disable
#
JENKINS_PORT="8081"

五、防火墙设置

firewall-cmd --zone=public --add-port=8081/tcp --permanent
firewall-cmd --zone=public --add-service=http --permanent
firewall-cmd --reload
firewall-cmd --list-all

六、权限

要确保jenkins用户对/var/lib/jenkins/和/var/log/jenkins/目录有读写权限。

[root@xa-dev-ci-1 plugins]# groups jenkins
jenkins : jenkins
[root@xa-dev-ci-1 plugins]# chown -R jenkins:jenkins /var/lib/jenkins/
[root@xa-dev-ci-1 plugins]# chown -R jenkins:jenkins /var/log/jenkins/

七、启动

sudo service jenkins restart 
sudo chkconfig jenkins on

八、使用浏览器访问，根据提示操做
