DevOps之四 Jenkins的安装与配置

CentOS 上 Jenkins 安装

一、添加yum repos，然后安装

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

二、Jenkins的安装目录

cd /var/lib/jenkins/

三、jenkins配置文件

Jenkins的默认端口是8080  如果被占用可以在这里修改

vi /etc/sysconfig/jenkins

## Type:        integer(:)

## Default:

## ServiceRestart: jenkins

#

# Port Jenkins is listening on.

# Set to - to disable

#

JENKINS_PORT=""

备注：端口最好使用1024 以上的端口，不然会报：无权限错误

四、修改Jenkins的JDK路径

vi /etc/init.d/jenkins

添加自己的jdk路径

# Search usable Java as /usr/bin/java might not point to minimal version required by Jenkins.

# see http://www.nabble.com/guinea-pigs-wanted-----Hudson-RPM-for-RedHat-Linux-td25673707.html

candidates="

/etc/alternatives/java

/usr/lib/jvm/java-1.8./bin/java

/usr/lib/jvm/jre-1.8./bin/java

/usr/lib/jvm/java-1.7./bin/java

/usr/lib/jvm/jre-1.7./bin/java

/usr/bin/java

/usr/java/jdk1.8.0_121/bin/java

/usr/java/jdk1.8.0_121/jre/bin/java

"

五、启动Jenkins

systemctl start jenkins

这时候会报错误：Warning: jenkins.service changed on disk. Run 'systemctl daemon-reload' to reload units.

解决方法：

systemctl daemon-reload

六、如果服务启动查看日志

cat  /var/log/jenkins/jenkins.log
