With load balancing, you can modify the configuration HTTP node as follows:
#设定http服务器, using its reverse proxy function to provide load balancing support http { #设定mime类型, the type is defined by the Mime.type file include / etc / Nginx / MIME . Types ; Default_type Application / Octet - Stream ; #设定日志格式 Access_log / var / Log / Nginx / Access . Log ; #省略上文有的一些配置节点 # ..... #设定负载均衡的服务器列表 Upstream Mysvr { #weigth参数表示权值, the higher the weight, the greater the chance of being assigned. Server 192.168 . 8.1x : 3128 Weight = 5 ; #本机上的Squid开启3128端口, you don't have to have squid. Server 192.168 . 8.2x : the Weight = 1 ; Server 192.168 . 8.3x : the Weight = 6 ; } Upstream MYSVR2 { #weigth参数表示权值, the higher the weight, the greater the chance of being assigned. Server 192.168 . 8.x : the Weight = 1 ; Server 192.168 . 8.x : the Weight = 6 ; } #第一个虚拟服务器 Server { #侦听192.80 Port of 168.8.x Listen the ; server_name 192.168 . 8.x ; #对aspx后缀的进行负载均衡请求 Location ~ .* \.aspx$ { #定义服务器的默认网站根目录位置 Root / Root ; #定义首页索引文件的名称 Index Index .

The above describes the Nginx load Balancer configuration---nginx learning path, including the aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
