安装jenkins

下载tomcat和jenkins war包

tomcat下载地址

https://mirrors.bfsu.edu.cn/apache/tomcat/tomcat-8

jenkisn下载地址

https://get.jenkins.io/war-stable

tomcat版本会更新，请根据版本下载，我这边用的是8.5.57，下次可能会是新版本

wget -P /opt   https://mirrors.bfsu.edu.cn/apache/tomcat/tomcat-8/v8.5.57/bin/apache-tomcat-8.5.57.tar.gz

cd /opt

tar xvf apache-tomcat-8.5.57.tar.gz

rm -rf  /opt/apache-tomcat-8.5.57/webapps/*

wget -P /opt/apache-tomcat-8.5.57/webapps/ https://ftp-nyc.osuosl.org/pub/jenkins/war-stable/2.263.1/jenkins.war

cd /opt/apache-tomcat-8.5.57/webapps/

mv jenkins.war  ROOT.war

vim /opt/apache-tomcat-8.5.57/bin/catalina.sh

JAVA_OPTS="-server -Xms2048m -Xmx2048m -XX:MetaspaceSize=512M  -Djava.awt.headless=true"

启动jenkins

sh /opt/apache-tomcat-8.5.57/bin/startup.sh

访问jenkins，ip:8080

cat /root/.jenkins/secrets/initialAdminPassword

添加agent

然后在dev的机器上ssh登陆jenkins机器一次即可

使用ldap登陆
