提示错误代码，我的centos版本是6.4的
[root@localhost /]# service mysqld start
Initializing MySQL database: 2021-05-28T18:32:38.764172Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
2021-05-28T18:32:38.767173Z 0 [ERROR] --initialize specified but the data directory has files in it. Aborting.
2021-05-28T18:32:38.767223Z 0 [ERROR] Aborting
怎么解决呢
[FAILED]
MySQL的data目录下有文件，需要将目录清空掉，然后对MySQL进行初始化再启动。
删除 /var/lib/mysql/ 文件夹，再试试重启
