Windows下永久解决数据库乱码 utf8 转 gbk

产生乱码原因

因为windows终端的默认字符集是gbk编码，而mysql数据库是utf8的编码，所以会产生乱码问题

解决乱码问题（临时修改）

询当前数据库默认编码：

mysql> show variables like 'character%';

修改为gbk编码：

mysql> set names gbk;

但是这只是临时修改，对新开启的终端无效。

解决乱码问题（永久）

修改MySQL的配置文件：my-default.ini

配置文件位于MySQL的安装目录

例如我的：C:\Program Files\MySQL\MySQL Server 5.7

[mysqld]character-set-server=gbk

# For advice on how to change settings please see

# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the

[mysqld]character-set-server=gbk

# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
# port = .....
# server_id = .....

# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
