官网兼容wordpress预览文章

##nginx

    location = / {
        error_page 588 = @wordpress;
        #如果有preview参数，则返回wordpress页面
        if ($arg_preview) {
            return 588;
        }
        add_header Cache-Control "no-store";
        add_header Pragma "No-cache";
        expires -1;
        etag off;
        root /data/pentaq-weui-wap/dist;
        try_files $uri $uri/ /index.html;

    location @wordpress {

nginx 当出现502状态时访问备用服务

先启动备用服务，再停主服务，然后更新主服务代码，最后启动主服务关闭备用服务。

达成服务无缝更新。 

##nginx

    location / {
        error_page 502 = @backup;
        proxy_pass http://127.0.0.1:4000;
        proxy_redirect off;
        proxy_set_header X-Forwarded-For             $proxy_add_x_forwarded_for; 
    }
    location @backup {
        proxy_pass http://127.0.0.1:5000;
        proxy_redirect off;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }

gitlab的相关信息

gitlab打包了nginx, redis, postgresql, sidekiq 和 unicorn 服务。
也因此在安装gitlab的机器上你不能再独立安装nginx，你可以直接使用gitlab提供的nginx。


相关配置文件Location
/var/opt/gitlab

启动、重启命令gitlab-ctl start gitlab-ctl stop gitlab-ctl restart
更多信息gitlab-ctl status gitlab-ctl help

只重启nginxsudo gitlab-ctl restart nginx

nginx单个IP的请求频率限制、并发连接限制

全局配置 ### nginx.conf
        limit_req_zone $binary_remote_addr zone=global_req_limit:10m rate=20r/s;         limit_req zone=global_req_limit burst=100 nodelay;
        limit_conn_zone $binary_remote_addr zone=global_conn_limit:10m;         limit_conn global_conn_limit 500;

        limit_conn_zone $binary_remote_addr zone=my_conn_limit:10m;

单个服务配置
看情况限制最大并发数, 比如websock长链接
### xxx.com.conf         
location /faye {             limit_conn my_conn_limit 12;  }
