openresty结合lua对域名参数做负载均衡

openresty结合lua对同一条域名判断参数做负载

1，配置一条域名 ,当https://hudiecaifus.net/?channelCode=gg_34 这条域名后缀参数等于gg_34的时候转发http://meigui_34

server {
    listen 80;
    server_name hudiecaifus.net www.hudiecaifus.net;
    root /software/mangguo站点/gg代理/hudiecaifus.net-no-cnzz;   #默认不统计

    location / {
        set_by_lua_block $gg_34 {
            local channel = { "gg_34" }; 
            for k, v in pairs( channel ) do
                if ngx.var.arg_channelCode == v then
                    return 1;
                end
            end
            return 0;
        }

        if ($gg_34) {
            proxy_pass http://meigui-gg_34;
        }
    }
}

2， 再新建一个文件touliang_upstream.conf

每个落地页分别建2个server段。一个统计。一个不统计

upstream meigui-gg_34 {
    # 不扣    server 127.0.0.1:8804 weight=7;
    #  扣量   server 127.0.0.1:8805 weight=3;
}

server {
    listen 8804;
    server_name 127.0.0.1;
    root /software/mangguo站点/gg代理/hudiecaifus.net;

    location = /index.html {
        set_by_lua_block $date {
             return ngx.today();
        }

        set_by_lua_block $c {
             if ngx.var.arg_channelCode ~= nil then
                 return ngx.var.arg_channelCode;
             end
             return "default";
        }

        set_by_lua_block $log_name {
             local name = ngx.var.date .. "-" .. ngx.var.c .. "-cnzz";  #访问生成对应的日志
             return name;        }

        access_log logs/$log_name.log;
    }
}

server {
    listen 8805;
    server_name 127.0.0.1;
    root /software/mangguo站点/gg代理/hudiecaifus.net-no-cnzz;  #不统计落地页

    location = /index.html {
        set_by_lua_block $date {
             return ngx.today();
        }

        set_by_lua_block $c {
             if ngx.var.arg_channelCode ~= nil then
                 return ngx.var.arg_channelCode;
             end
             return "default";
        }

        set_by_lua_block $log_name {
             local name = ngx.var.date .. "-" .. ngx.var.c .. "-no-cnzz";
             return name;
        }

        access_log logs/$log_name.log;
    }
}

2.1, 优化后的配置文件，放在同一个目录下面，方便工作维护
新建touliang_xin.conf

erver {
    listen 80;
    server_name aiktv.com www.aiktv.com ;
    root /software/nsvwang站点/nsvwang落地页1;

    location ~* (\.html|/)$ {
        if ($arg_channelCode = 'nsw_1') {
            proxy_pass http://nsvwang-touliang-nsw_1;
        }

        if ($arg_channelCode = 'nsw_c1') {
            proxy_pass http://nsvwang-touliang-nsw_c1;
        }
    }
}

再建一个touliang_upstram.conf

upstream nsvwang-touliang-nsw_1 {
    # 不扣
    server 127.0.0.1:12001 weight=5;
    # 扣量
    server 127.0.0.1:12002 weight=5;
}


server {
    listen 12001;
    server_name 127.0.0.1;
    root /software/nsvwang站点/nsvwang落地页1;

    location  ~* (\.html|/)$  {
        set_by_lua_block $date {
             return ngx.today();
        }

        set_by_lua_block $c {
             if ngx.var.arg_channelCode ~= nil then
                 return ngx.var.arg_channelCode;
             end
             return "default";
        }

        set_by_lua_block $log_name {
             local name = ngx.var.date .. "-" .. ngx.var.c .. "-op";
             return name;
        }

        access_log logs/$log_name.log;
    }
}

server {
    listen 12002;
    server_name 127.0.0.1;
    root /software/nsvwang站点/nsvwang落地页1;
    index no-op.html;

    location  ~* (\.html|/)$  {
        set_by_lua_block $date {
             return ngx.today();
        }

        set_by_lua_block $c {
             if ngx.var.arg_channelCode ~= nil then
                 return ngx.var.arg_channelCode;
             end
             return "default";
        }

        set_by_lua_block $log_name {
             local name = ngx.var.date .. "-" .. ngx.var.c .. "-touliang";
             return name;
        }

        access_log logs/$log_name.log;
    }
}

3， 查看当天代理线的访问次数

进入源服务器

cd /etc/nginx/logs/

cat 2022-03-12-gg_34-cnzz.log |wc -l
83746 

#表示gg_34代理线当天总访问83736次，走统计页面

cat 2022-03-12-gg_34-no-cnzz.log |wc -l 
36845
#表示gg_34代理线当天总访问36845次，不走统计页面

4， 查看对应域名有多少代理线，或者查看代理线有哪些域名访问

cat check.sh 
#!/bin/sh

if [ ! -z $1 ]; then
  grep $1  /etc/nginx/logs/access.log | awk '{ printf ("%s --- %s\n",$3,$5) }' | grep $1 | grep channelCode | sort | uniq -c | sort -n
  #grep $1  access.log-20220413 | awk '{ printf ("%s --- %s\n",$3,$5) }' | grep $1 | grep channelCode | sort | uniq -c | sort -n
else
  echo 参数为空
fi

使用脚本

./check.sh woaktv.cc  #参数1输入域名，就会统计出对应的代理线以及访问量


./check.sh  gg_34     #参数1输入代理线参数，就会统计出对应的域名以及访问量
