1.确定java环境的安装（如果没有java环境需要配置java环境变量）

java -version

#编辑群居配置文件
vim /etc/profile

#在最下面，按i进入insert模式，添加一下内容
JAVA_HOME=jdk路径
export JAVA_HOME
CLASSPATH=.:$JAVA_HOME/lib
export CLASSPATH
PATH=$PATH:$JAVA_HOME/bin:$CLASSPATH
export PATH

#重新加载配置
source /etc/profile

2.获取Jenkins源文件

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

3.导入Jenkins公钥

rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.key

4.yum安装Jenkins

yum install -y jenkins

5.Jenkins配置文件配置java环境

vi /etc/init.d/jenkins

6.配置文件

/usr/lib/jenkins/ #jenkins安装目录，WAR包会放在这里。
 
/etc/sysconfig/jenkins #jenkins配置文件

/var/lib/jenkins/ #默认的JENKINS_HOME。 

/var/log/jenkins/jenkins.log #日志文件

7.启停Jenkins

service jenkins start
service jenkins stop
service jenkins restart

默认端口8080，ip:8080访问，注意虚拟机要开放端口，阿里云配置网络安全组

8.jenkins无法安装插件问题

• jenkins安装插件报错：原因是默认证书有问题

• 更新站点：https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json

• 进入jenkins站点更新目录修改默认json配置

cd /var/lib/jenkins/updates/

• 全局替换default.json里面的下载插件地址

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

• 查找证书路径

find / -type f -name cacerts

• 修改jenkins配置文件

vi /etc/sysconfig/jenkins

JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true -Djavax.net.ssl.trustStore=/etc/pki/ca-trust/extracted/java/cacerts"

• 重启jenkins

service restart jenkins
