你是否遇见以下问题在MySQL重启时出现问题，报出了以下的错误，现在我将告诉你遇见以下错误怎么处理。

[root@C_150 mysql]# systemctl restart mysqld
Job for mysqld.service failed because the control process exited with error code. See "systemctl status mysqld.service" and "journalctl -xe" for details.

当出现了上面的错误，我们可以看出它提供了两条命令“systemctl status mysqld.service”和“journalctl -xe”来帮助我们来查看错误的详情。

使用“systemctl status mysqld.service”命令，可能你看不懂下面密密麻麻的出现的在说什么，但是我们主要看的就是MySQL的状态，我现在的状态就是deactivating，显然服务没开启。然后你只需要看error是什么报错。

[root@C_150 mysql]# systemctl status mysqld.service

找到了error就知道了报错信息, 我们这两句都有error

Dec 23 04:27:19 C_150 mysqld_pre_systemd[76561]: 2022-12-22T20:27:19.331670Z 0 [ERROR] --initialize specified but the data direc…rting.

没关系我们继续执行另一条命令

[root@C_150 mysql]# journalctl -xe
...
2022-12-25T01:59:21.237781Z 0 [ERROR] --initialize specified but the data directory has files in it. Aborting.
2022-12-25T01:59:21.239775Z 0 [ERROR] Aborting
...

前面的都可以不用查看，看到error报错信息提示来判断错误原因。“initialize specified but the data directory has files in it.”意思是初始化数据目录时发现目录里面有文件，可能原因是之前运行过命令目录中已生成文件。只要我们找到MySQL的数据目录并删除里面的文件即可解决。

查看MySQL指定的数据目录存放路径
# cat /etc/my.cnf
......省略内容...............
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock

datadir是我们安装MySQL时默认指定的存放文件的数据目录，进入文件中删除里面的目录即可。文章来源地址https://www.toymoban.com/news/detail-577352.html

# cd /var/lib/mysql
# rm -rf *
