看到错误原因了:

170909 12:05:55 [ERROR] /usr/local/mysql/bin/mysqld: unknown variable ‘explicit_defaults_for_timestamp=true’

所以去搜索这个:

mysqld: unknown variable ‘explicit_defaults_for_timestamp=true’

其中:

这个参数是之前fzhost中的mysql配置,之前mysql记得址5.0.1的版本

而我此处linode中的mysql是5.5.56了。

所以估计是废弃的参数了。

Mysql启动失败 MYSQL:The server quit without updating PID file – Youn丶 – 博客园

MySQL :: Re: TIMESTAMP with implicit DEFAULT value is deprecated

mysql – How to enable explicit_defaults_for_timestamp? – Stack Overflow

explicit_defaults_for_timestamp

Introduced
5.6.6
Deprecated
5.6.6

This system variable determines whether the server enables certain nonstandard behaviors for default values and NULL-value handling in TIMESTAMP columns. By default, explicit_defaults_for_timestamp is disabled, which enables the nonstandard behaviors.

不管了:

5.6.6中,引入了explicit_defaults_for_timestamp,但是同时新版中就又废除了:

explicit_defaults_for_timestamp

看起来,感觉这个参数也没啥太大价值,所以直接去掉,就可以了。

【总结】

vi /etc/my.cnf

把之前加入的:

explicit_defaults_for_timestamp = true

中的去掉,就可以了。
