解壓到/usr/local/
[root@localhost src]# tar xf apache-tomcat-9.0.11.tar.gz -C /usr/local/
將解壓後的tomcat包的軟件接，命名tomcat
[root@localhost src]# cd /usr/local

因爲是java程序，一般服務器內存至少8-16g ，並且tomcat在一臺服務器上不可能只跑一個
進入tomcat包配置，以及介紹
[root@localhost local]# cd tomcat/

[root@localhost webapps]# cd不同端口
第二個tomcat同ip不同端口的網頁也搭建成功
下面開始搭建nging和數據庫
可以在其他服務器搭建也可以就在本服務器搭建，
使用nginx，實現負載均衡
可在本服務器設置，也可以在其他服務器設置反向代理tomcat網頁的ip和端口
