MySQL Daemon failed to start.

Post by crachbach12 » 2018/05/18 17:54:20

This is my first post to ask for help, so I hope I can help you help me .

[root@vmi183370 ~]# service mysqld restart
Stopping mysqld: [ OK ]
MySQL Daemon failed to start.
Starting mysqld: [FAILED]
[root@vmi183370 ~]#

when I pull mysqld.log I see the following:
nano /var/log/mysqld.log

180518 15:15:19 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
180518 15:15:19 InnoDB: Initializing buffer pool, size = 8.0M

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.

It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 338336 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

when I pull tail I see the following:

tail /var/log/mysqld.log

[root@vmi183370 ~]# tail /var/log/mysqld.log
/usr/libexec/mysqld() [0x787c3d]
/usr/libexec/mysqld(recv_recover_page+0x34f) [0x7896ff]

/usr/libexec/mysqld() [0x7c8ce0]
/lib64/ [0x3386807aa1]
/lib64/ [0x33864e8bcd]
The manual page at contains
information that should help you find out what is causing the crash.
180518 17:47:35 mysqld_safe mysqld from pid file /var/run/mysqld/ ended

please help
Best regards
