#安装tomcat
yum install tomcat6 tomcat6-webapps tomcat6-admin-webapps

#安装httpd
yum install httpd
#修改httpd端口 改为81
vi /etc/httpd/conf/httpd.conf
#启动会出现Permission denied: make_sock: could not bind to address
#下面命令增加81非常规端口
semanage port -a -t http_port_t -p tcp 81
#下面命令安装semanage
yum install policycoreutils-python

#安装nginx
yum install nginx

#修改配置文件配置虚拟机
#修改下面的listen ip和server_name就可实现不同的转发
