写在前面

使用Nginx做反向代理服务器的时候,我们偶尔会有希望用户无论使用大写还是小写,
都匹配到同一个代理,这里就用到了忽略大小写匹配正则

Nginx具体配置

upstream lb_test01 {
    server 10.0.0.1:7002 weight=10 max_fails=3 fail_timeout=15s;
    server 10.0.0.1:7002 weight=10 max_fails=3 fail_timeout=15s;
}
upstream lb_test02 {
    server 10.0.0.1:7005 weight=10 max_fails=3 fail_timeout=15s;
    server 10.0.0.1:7005 weight=10 max_fails=3 fail_timeout=15s;
}
upstream lb_test03 {
    server 10.0.0.1:7007 weight=10 max_fails=3 fail_timeout=15s;
    server 10.0.0.1:7007 weight=10 max_fails=3 fail_timeout=15s;
}
server {
    listen       80;
    server_name api.itttl.com;

    location /one {
        rewrite (?i)^/conf(.*) http://www.itttl.com/$1 permanent;
    }

    location ~* (?i)^/getcount {
        proxy_pass http://lb_actiontracker;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_redirect     off;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        access_log  /data/logs/nginx/access/actiontracker.log;
    }
    location ~* (?i)^/getlist {
        proxy_pass http://lb_adtracker;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_redirect     off;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        access_log  /data/logs/nginx/access/adtracker.log;

    }
}
