我刚刚发现 Wordpress 网站不再运行。打开时example.in，它只显示文本Error establishing a database connection。wp 网站是文件夹/var/www/examplewp
我在同一台服务器上运行着其他非基于 PHP 的网站，运行顺畅。即使xxx.example.in是非基于 PHP 的网站也可以正常运行。
我尝试打开我在 WP 的基本文件夹中创建的文件（例如example.in/readmore.html或） ，并且可以正常工作。example.in/hello.txt
详细信息如下：

我尝试使用 重启服务器，sudo service nginx restart但无济于事。甚至 HTML 或 TXT 文件都无法打开。我尝试使用命令行sudo service php7-fpm restart，但得到的响应如下：
Failed to restart php7-fpm.service: Unit php7-fpm.service not found.
我可以打开包含以下内容的 info.php 文件phpinfo();并查看所有 PHP 相关文件。
我也检查了错误日志但它是空的：/var/log/nginx/wp_client_error.log
我尝试使用此命令 land: 重新启动 mysql，sudo /etc/init.d/mysql start但出现以下错误：
[....] Starting mysql (via systemctl): mysql.serviceJob for mysql.service failed because the control process exited with error code.
See "systemctl status mysql.service" and "journalctl -xe" for details.
**failed!**
命令行得到这个：sudo netstat -tulpn
