#
# The following options will be read by MySQL client applications.
# Note that only client applications shipped by MySQL are guaranteed
# to read this section. If you want your own MySQL client program to
# honor these values, you need to specify it as an option during the
# MySQL client library initialization.
#
[mysql]
# 設置mysql客戶端默認字符集
default-character-set=utf8
[mysqld]
#權限問題
# 設置3306端口

# 設置mysql的安裝目錄
basedir=C:\Program Files (x86)\mysql-8.0.17-winx64
# 設置mysql數據庫的數據的存放目錄
datadir=C:\Program Files (x86)\mysql-8.0.17-winx64\data
# 允許最大連接數max_connections=200
# 服務端使用的字符集默認為8比特編碼的latin1字符集
character-set-server=utf8
# 創建新表時將使用的默認存儲引擎
default-storage-engine=INNODB
