部署LNMP架构时安装MySQL的报错（--initialize specified but the data directory has files in it. Aborting.）！

mysql数据库装完了，准备初始化数据库时出现问题“–initialize specified but the data directory has files in it. Aborting.”

[root@localhost mysql]# bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
2021-06-22T16:41:37.699189Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
2021-06-22T16:41:37.700235Z 0 [ERROR] --initialize specified but the data directory has files in it. Aborting.
2021-06-22T16:41:37.700254Z 0 [ERROR] Aborting

错误原因，这是我的mysql数据库已经初始化过，但是代码敲错出现问题，而我们不能再用这个进行初始化，解决方法：

vim /etc/my.cnf      #找到以下位置的文件，并删除它

[root@localhost mysql]# rm -rf /usr/local/mysql/data

#### 再重新初始化系统即可
[root@localhost mysql]# bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
