两个实例同时监听8080端口必然会产生冲突，所以必须修改.

tomcat在Linux 下默认工作模式是bio,性能非常低,建议使用apr或者nio，
这里改为nio,即非阻塞IO,性能比较好。

sed
-i.bak

tomcat02同理

sed
‘s/tomcat01/tomcat02/g‘
tomcat01.service > tomcat02.service

4、启动服务

|
systemctl
enable
tomcat01
systemctl
enable
tomcat02
systemctl start tomcat01
systemctl start tomcat02
|
5、查看进程
ps aux |grep tomcat
附上一份nginx反向代理tomcat的配置文件
proxy_cache_path /var/cache/nginx/proxy_cache levels=1:2 keys_zone=static:10m inactive=1h max_size=1g;
