centos8+nginx1.17+tomcat9集群

1.我们这里准备3台 tomcat,端口分别是8081、8082、8083,针对同个域名,每次用 Nginx实现不同的转发,分别在每个 tomcat的 webapps目录下创建ROOT目录,并创 index. htm,分别在html的body里标记1/2/3以示区分
2.修改tomct的webapp/root下的index.jsp文件区分不同的tomcat
3.安装nginx并指定安装目录
4.在浏览器中输入ip[http://192.168.2.128/](http://192.168.2.128/)地址
快速启动配置项目
./tomcat1/bin/startup.sh
./tomcat2/bin/startup.sh
./tomcat3/bin/startup.sh
./nginx/sbin/nginx
快速关闭配置项
./tomcat1/bin/shutdown.sh
./tomcat2/bin/shutdown.sh
./tomcat3/bin/shutdown.sh
./nginx/sbin/nginx -s stop
