大致步骤
001 分布式构建
步骤详见：【分布式构建（Master/Slave）】
1634712393035.png
002 Git参数化
0001 设置分支
1634712872062.png
0002 设置发布节点（17服务器）
1634712932678.png
0003 新建项目

1634713757320.png
0004 推送现有文件夹到新建项目
#把18服务器的项目tomcat-java-demo-master推送到gitLab
[root@bogon tomcat-java-demo-master]# git config --global user.name "lql"
[root@bogon tomcat-java-demo-master]# git config --global user.email "lql_h@163.com"
[root@bogon ~]# cd tomcat-java-demo-master
[root@bogon tomcat-java-demo-master]# git init
[root@bogon tomcat-java-demo-master]# git remote add origin http://gitlab.pcitc.com/test/demo.git
[root@bogon tomcat-java-demo-master]# git add .
[root@bogon tomcat-java-demo-master]# git commit -m "Initial commit"
[root@bogon tomcat-java-demo-master]# git push -u origin master
#注意
推送master的权限至少是Maintainer
003 配置git地址
1634717804581.png
0001 做一个测试
1634718309331.png
#17的服务器，即slave构建
[root@localhost jenkins_home]# cd /opt/jenkins_home/workspace/
[root@localhost workspace]# ls
java-demo
004 代码编译构建
0001 修改阿里云仓库
#网址
https://developer.aliyun.com/mvn/guide
#阿里云仓库
<mirror>
<id>aliyunmaven</id>
<mirrorOf>*</mirrorOf>
<name>阿里云公共仓库</name>
<url>https://maven.aliyun.com/repository/public</url>
</mirror>
#修改setting
/usr/local/maven/conf
0002 构建shell测试
mvn clean package -Dmaven.test.skip=true
ls
ls target
1634721059090.png
005 拷贝构建文件到远程Web服务器
0001 清理tomcat
[root@localhost webapps]# tar -xzvf apache-tomcat-8.5.59.tar.gz
[root@localhost webapps]# mv apache-tomcat-8.5.59 /usr/local/tomcat
[root@localhost webapps]# cd /usr/local/tomcat/
[root@localhost webapps]# cd webapps/
[root@localhost webapps]# rm -rf *
0002 修改SSH Servers的远程目录
1634722367970.png
0003 构建Send files
target/*.war
target/
usr/local/tomcat/webapps
ls /usr/local/tomcat/webapps
1634722568616.png
1634722601754.png
0004 检查结果
[root@bogon java-demo]# cd /usr/local/tomcat/webapps/
[root@bogon webapps]# ls
ly-simple-tomcat-0.0.1-SNAPSHOT.war
006 部署程序
# 备份已部署的程序
tomcat=/usr/local/tomcat
cd $tomcat/webapps
mv ROOT.war /data/backup/$(date +"%F_%T")_ROOT.war
# 部署新程序并重启Tomcat
mv ly-simple-tomcat-0.0.1-SNAPSHOT.war ROOT.war
pid=$(ps -ef |grep tomcat |egrep -v 'grep' |awk '{print $2}')
[ -n "$pid" ] && kill -9 $pid
JAVA_HOME=/usr/local/jdk
export JAVA_HOME
/bin/bash /usr/local/tomcat/bin/startup.sh
