更改 my.cf 后 MySQL 无法启动

问题描述

我在一个网站上工作，我收到了这个 MySQL 错误:

I'm working on a website and I'm getting this MySQL error:

"(...) 这与 sql_mode=only_full_group_by (...) 不兼容"

"(...) this is incompatible with sql_mode=only_full_group_by (...)"

我一直在寻找答案，但我意识到我必须更改 MySQL 的 sql_mode.所以我在/etc/mysql/my.cnf 中添加了以下行:

I've looked for an answer and I realized I had to change the sql_mode of my MySQL. So I've added the following line to /etc/mysql/my.cnf:

sql_mode="STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

但是现在当我执行 sudo service mysql restart 时，它需要很长时间，然后显示此消息:

But now when I executed sudo service mysql restart it takes a really long time and then shows this message:

Job for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details.

所以现在我删除了该行，每次启动 PC 时都必须手动执行该命令.

So now I removed that line and I have to execute the command by hand everytime I boot my PC.

有人可以帮我吗?

推荐答案

我没有更改文件 /etc/mysql/my.cnf，而是应用了 /etc/中的更改mysql/mysql.conf.d/mysqld.cnf 文件，终于成功了.

Instead of changing the file /etc/mysql/my.cnf, I applied the changes in the /etc/mysql/mysql.conf.d/mysqld.cnf file and it worked, finally.
