wordpress登录后站点出现 502错误

最近发现，wordpress 4.7 在登录后，如果再次访问自己站点会直接出现502错误，但是如果非登录状态，则访问都是正常的。这个现象非常奇怪。无论如何，先登录服务器看日志：

tail -f /var/log/nginx/error.log

然后在登录状态下访问我的网站，发现有如下日志，

2016/12/21 14:59:57 [error] 8551#0: *26 upstream sent too big header while reading response header from upstream, client: **.*.*.*, server: idocbox.com, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "idocbox.com", referrer: "http://idocbox.com/wp-admin/plugins.php?plugin_status=all&paged=1&s"

看来是头信息过大导致超时了，所以出现了502错误。一番简单搜索，得到如下解决方案：

sudo vi /etc/nginx/sites-enabled/idocbox.com

在里面增加

                fastcgi_buffer_size 128k;
                fastcgi_buffers 32 32k;

修改后配置片段，

location ~ \.php$ {
                fastcgi_buffer_size 128k;
                fastcgi_buffers 32 32k;
                fastcgi_split_path_info ^(.+\.php)(/.+)$;
        #       # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
        #
        #       # With php5-cgi alone:
        #       fastcgi_pass 127.0.0.1:9000;
        #       # With php5-fpm:
                fastcgi_pass unix:/var/run/php5-fpm.sock;
                fastcgi_index index.php;

        include fastcgi_params;
        }

然后重启nginx，

sudo service nginx restart

验证：再次在登录状态下访问网站，网站正常了，日志里面也没有了那个“upstream sent too big” 错误。
