MySQL5.7 初始化啓動報錯:initialize specified but the data directory has files in it. Aborting
今天安裝好mysql5.7啓動是報下面的錯誤，然後想到需要初始化mysql 使用 mysqld --initialize
2019-10-31T07:52:53.807647Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use –explicit_defaults_for_timestamp server option (see documentation for more details).
2019-10-31T07:52:53.809065Z 0 [ERROR] –initialize specified but the data directory has files in it. Aborting.
2019-10-31T07:52:53.809095Z 0 [ERROR] Aborting
最後仔細看了報錯的原因，是因爲第一次初始化的時候沒初始化好，產生樂data目錄，刪除data目錄重新初始化即可，順便提一下如果mysqld -install註冊失敗，首先要使用管理員權限的命令提示符，然後便可註冊成功，正常使用mysql
