nginx负载均衡的配置。把请求通过nginx的反向代理分发到多台服务器处理，可以减轻单台服务器的处理压力，提高访问速度。
一、增加nginx负载均衡代码
1.nginx配置文件http模块中增加
#请求处理的服务器列表 upstream zixuephp { server 127.0.0.1:81 weight=1; #服务器1 weight权重，这里是访问6词有一次是这台服务器 server 106.12.107.148:80 weight=5; #服务器2 }2.请求反向代理
server { listen 80; #多域名用空格隔开 server_name zixuephp.net www.zixuephp.net m.zixuephp.net; #设置默认访问首页 index index.html index.php; #反向代理到服务器池 location / { proxy_pass http://zixuephp; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; } }二、完整nginx.conf配置文件代码
这里配置的是负载服务器和主服务器为同一台服务器
