我的mysql服务器无法重新启动
我正在安装wordpress插件,它崩溃了,然后我试图重新启动服务,我有一个错误:

root@ns3371000:~# /etc/init.d/mysql start
[FAIL] Starting MySQL database server: mysqld . . . . . . . . . . . . . . failed!

这是我在安全模式下启动它时的日志:

mysqld_safe Logging to '/var/log/mysql.err'.

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed, 
something is definitely wrong and this may fail.

key_buffer_size=16777216
read_buffer_size=131072
max_used_connections=0
max_threads=151
thread_count=0
connection_count=0
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 346701 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

where mysqld died. If you see no messages after this, something went
terribly wrong...

The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains
information that should help you find out what is causing the crash.

我不想把我现有的数据库都弄丢,任何能让我解决问题的东西都会很好

如果数据库损坏,您可以尝试以恢复模式访问它。在配置文件(my.ini)中,尝试添加:

[mysqld]
innodb_force_recovery = N

其中n是1到6。然后,重新启动服务器。
更多信息请参见:https://dev.mysql.com/doc/refman/8.0/en/forcing-innodb-recovery.html
至少,您应该能够以只读模式访问数据库以进行转储。
