#CentOS 2 Building Nginx Web ServicesNeed to build the same as CentOS 1
Close Iptables Firewall
Install the same version of the Java environment
Installation configuration Tomcat, version consistency
Note that when writing index.jsp Web pages, to differentiate between load balancing we wrote two different pages to make it easy to differentiate
