基于nginx的负载均衡

http里面的server段配置如下：

server

{

   listen 80;

   listen 443 ssl http2;

   listen [::]:443 ssl http2;

   listen [::]:80;

   server_name fz1.wlphp.com 39.105.195.211;

   index index.php index.html index.htm default.php default.htm default.html;

   root /www/wwwroot/fz1.wlphp.com;

   #SSL-START SSL相关配置，请勿删除或修改下一行带注释的404规则

   #error_page 404/404.html;

   ssl_certificate    /etc/letsencrypt/live/fz1.wlphp.com/fullchain.pem;

   ssl_certificate_key    /etc/letsencrypt/live/fz1.wlphp.com/privkey.pem;

   ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

   ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;

   ssl_prefer_server_ciphers on;

   ssl_session_cache shared:SSL:10m;

   ssl_session_timeout 10m;

   error_page 497  https://$host$request_uri;

   #SSL-END

   #ERROR-PAGE-START  错误页配置，可以注释、删除或修改

   error_page 404 /404.html;

   error_page 502 /502.html;

   #ERROR-PAGE-END

   #PHP-INFO-START  PHP引用配置，可以注释或修改     #include enable-php-00.conf;    

   #PHP-INFO-END

   #REWRITE-START URL重写规则引用,修改后将导致面板设置的伪静态规则失效

   include /www/server/panel/vhost/rewrite/fz1.wlphp.com.conf;

   #REWRITE-END      #负载均衡      location / {        proxy_pass        http://upstream1;         proxy_set_header   Host             $host;         proxy_set_header   X-Real-IP        $remote_addr;         proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;    }

   #禁止访问的文件或目录

   location ~ ^/(\.user.ini|\.htaccess|\.git|\.svn|\.project|LICENSE|README.md|qq)

   {

       return 404;

   }

   #一键申请SSL证书验证目录相关设置

   location ~ \.well-known{

       allow all;

   }

   location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$

   {

       expires   -1;

       #add_header Cache-Control no-cache;

       error_log off;

       access_log /dev/null;

   }

   location ~ .*\.(js|css)?$

   {

       expires      12h;

       error_log off;

       access_log /dev/null;

   }

   access_log  /www/wwwlogs/fz1.wlphp.com.log;

   error_log  /www/wwwlogs/fz1.wlphp.com.error.log;

} upstream  upstream1   {     server   127.0.0.1:71;     server   127.0.0.1:72;     server   127.0.0.1:73;     server   127.0.0.1:74;     server   127.0.0.1:75;     ip_hash;

}    

ip_hash(同一ip会被分配给固定的后端服务器,解决session问题)
