问题描述：
今天下午开发过来说开发库无法连接了，登录服务器后发现mysql进程down了
启动mysql：
/bin/sh /usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &
启动时报错，无法正常启动mysql
查询告警日志文件
如果错误信息如下
2018-07-03 15:19:11 7f6e0dc9e700 InnoDB: Operating system error number 13 in a file operation.
InnoDB: The error means mysqld does not have the access rights to

InnoDB: Failing assertion: ret
InnoDB: We intentionally generate a memory trap.

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=8388608
read_buffer_size=262144
max_used_connections=5
max_threads=1024
thread_count=3
connection_count=3
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 545584 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
Thread pointer: 0x511a8b0
Attempting backtrace. You can use the following information to find out
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.
通过上述报错日志内容分析可能是权限导致的
错误13说明没有权限。使用命令
chmod -R 777 可以解决
[root@dev mysql]# chmod -R 777 /usr/local/mysql/
[root@dev mysql]# chown -R mysql:mysql /usr/local/mysql/
[root@dev mysql]# chmod -R 777 /mysql/data/
[root@dev mysql]# chown -R mysql:mysql /mysql/data/
提示一下：这个error number 就是系统的错误号，也是程序里的errorno
