安装前准备

注：jenkins依赖jdk环境，需提前安装配置（如已安装请跳过）

一、jdk8安装配置

jdk8下载地址：https://www.oracle.com/java/technologies/javase/jdk8-arm-downloads.html

1）解压

# tar -zxvf jdk-8u181-linux-x64.tar.gz -C /usr/local

2）配置环境变量

# vim /etc/profile

添加如下：

export JAVA_HOME=/usr/local/jdk1.8.0_181
export PATH=$JAVA_HOME/bin:$PATH

3）source生效并查看版本

# source /etc/profile

# java -version

java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)

4）添加jdk8软链接至默认

# ln -s /usr/local/jdk1.8.0_181/bin/java /usr/bin/java

二、jenkins安装配置

1）下载jenkins

# wget https://mirrors.tuna.tsinghua.edu.cn/jenkins/redhat-stable/jenkins-2.346.1-1.1.noarch.rpm

2）安装jenkins

# rpm -ivh jenkins-2.346.1-1.1.noarch.rpm

3）修改jenkins配置

# vim /etc/sysconfig/jenkins

修改内容：

JENKINS_USER="root"

JENKINS_PORT="8080" #根据端口实际使用情况修改

4）更改国内源：

# sed -i 's/http:\/\/updates.jenkins-ci.org\/download/https:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins/g' /var/lib/jenkins/updates/default.json && sed -i 's/http:\/\/www.google.com/https:\/\/www.baidu.com/g' /var/lib/jenkins/updates/default.json

5）启动jenkins并加入开机启动

# systemctl start jenkins && systemctl enable jenkins

# systemctl status jenkins
