2. Install nginx

3. Copy two copies of tomcat, namely tomcat1 and tomcat2

cd /usr/local/
mv tomcat/ tomcat1/
cp tomcat1/ tomcat2/

4. Modify the configuration file server.xml, mainly to modify the port number

4.1 There is no need to modify the one on tomcat1, go check it out

vim /usr/local/tomcat1/conf/server.xml

shutdown 端口：8005  主要负责启动关闭.   
http端口：8080 可以通过web页面直接访问（nginx+tomcata整合）  

4.2 Modify the port on tomcat2, change 8080 to 8081, change 8005 to 8006

vim /usr/local/tomcat2/conf/server.xml 

5. Start two tomcat

5.1 start

[root@slave2 sbin]# cd /usr/local/tomcat1
[root@slave2 tomcat1]# bin/startup.sh 

[root@slave2 sbin]# cd /usr/local/tomcat2
[root@slave2 tomcat2]# bin/startup.sh 

5.2 View

http://192.168.1.103:8080/
http://192.168.1.103:8081/

6. Configure the nginx.conf file

[root@slave2 tomcat1]# cd /usr/local/nginx/
[root@slave2 nginx]# vim conf/nginx.conf

6.1 Add the following code to the file

upstream nini{
    
    
            server 192.168.1.103:8080;
            server 192.168.1.103:8081;
        }

6.2 Add the following code in the location

proxy_pass http://nini;

7. Start nginx

vim conf/nginx.conf
sbin/nginx

8. Directly using ip to enter nginx is to enter tomcat
