mac 增加 my.cnf

發布時間：2018-04-25作者：laosun閱讀(8133)

mysql下沒有my.cnf，如果想要修改一些配置還挺懵逼的，網上找了一些資料，經過博主親測沒有問題，發篇文章一為共享，二為做個備忘。

博主使用的mysql 為 5.7.22

首先查看mysql安裝目錄下support-files文件夾下是否有my-default.cnf這個文件sun:support-files?sun$?pwd

/usr/local/mysql/support-files

sun:support-files?sun$?ll

total?48

-rw-r--r--??1?root??wheel????773??3??4?21:40?magic

-rwxr-xr-x??1?root??wheel????894??3??4?22:27?mysql-log-rotate*

-rwxr-xr-x??1?root??wheel??10585??3??4?22:27?mysql.server*

-rwxr-xr-x??1?root??wheel???1061??3??4?22:27?mysqld_multi.server*

如果有，就好辦了，直接轉移到/etc下，并且修改名字為my.cnf

sun:support-files?sun$?mv?/usr/local/mysql/support-files/my-default.cnf?/etc/my.cnf

如果沒有則需要自己創建一個文件。

sun:support-files?sun$?vim?/etc/my.cnf??#會打開創建一個新的文件，將下邊的內容復制進去
