使用Apache做负载均衡和Web服务器
使用Apache做负载均衡和Web服务器，并启用deflate,gzip压缩。配置httpd.conf如下：
LoadModule proxy_module modules/mod_proxy.so
#LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
#LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule proxy_http_module modules/mod_proxy_http.soLoadModule deflate_module modules/mod_deflate.so
LoadModule headers_module modules/mod_headers.so
