Safari 浏览器无法打开页面

Safari 浏览器无法打开页面 “https://www.crifan.com/”。
错误是:“FetchEvent.respondWith received an error: Returned response is null.” (WebKitServiceWorker:0)
去Vultr重启:
https://my.vultr.com/subs/?SUBID=24533431
然后出错:
估计数据库出错了?
[[email protected] ~]# service mysqld mydslq
Usage: mysqld  {start|stop|restart|reload|force-reload|status}  [ MySQL server options ]
[[email protected] ~]# service mysqld status
MySQL is not running, but lock file (/var/lock/subsys/mysql[FAILED]
[[email protected] ~]# service mysqld restart
MySQL server PID file could not be found!                  [FAILED]
Starting MySQL..                                           [  OK  ]
[[email protected] ~]# service mysqld status 
MySQL running (5406)                                       [  OK  ]
然后再去试试
问题依旧。
不是空间问题:
# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/vda1        79G   71G  4.3G  95% /
devtmpfs        1.9G     0  1.9G   0% /dev
tmpfs           1.9G     0  1.9G   0% /dev/shm

tmpfs           1.9G     0  1.9G   0% /sys/fs/cgroup

再去vultr重启VPS
再去试试

发现是500 服务器内部出错

有些数据表无效。若您希望让WordPress尝试修复它们,请点击“修复数据库”按钮。修复过程需要一点时间,请耐心等待。
修复数据库
WordPress还可以尝试优化数据库,这在某些情况下能提高数据库性能。修复和优化数据库的过程需要一段时间,请耐心等待——在此期间我们会锁定(lock)数据表。

然后就可以正常登录了:
网站也能打开了:
https://www.crifan.com/
后记:
登录后,发现有更新
其中有个是:Redis的缓存
Redis Object Cache
难道是别人说的,是这个插件问题?
看来又不是太像
【总结】
此处crifan.com的WordPress,访问主页
www.crifan.com
出错:
Safari 浏览器无法打开页面 “https://www.crifan.com/”。
错误是:“FetchEvent.respondWith received an error: Returned response is null.” (WebKitServiceWorker:0)

无法访问此网站
网址为 https://www.crifan.com/ 的网页可能暂时无法连接,或者它已永久性地移动到了新网址。
ERR_FAILED
且用Chrome调试可以看到500,属于内部服务器错误
折腾半天,以为是服务器本身有问题
经排查,确认php,mysql都没问题
service mysqld mydslq
service mysqld restart
最后是:
访问后台控制页面
https://www.crifan.com/wp-admin
发现是数据库有问题
然后按照提示修复数据库后,即可解决问题。
