安装Java

• 这里选择安装jdk8
• 上传安装包到服务器并解压移动到合适位置

tar -zxvf jdk-xxxxx
mkdir -p /opt/jdk8
mv jdk-xxxxx/* /opt/jdk8/

• 配置环境

vim /etc/profile

//追加/etc/profile文件内容
export JAVA_HOME=/opt/jdk8/
export PATH=$JAVA_HOME/bin:$PATH

//配置生效
source /etc/profile

• 测试

java -version

安装Jenkins

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

• 修改Jenkins配置

vim /etc/syscofig/jenkins
//修改内容如下：
JENKINS_USER="root"
JENKINS_PORT="8000"

• 启动Jenkins
