docker修改mysql容器配置文件解决中文乱码的问题

解决方法：

• 1.进入容器

• 2.进入etc/mysql,查看my.cnf文件，说明要修改的文件在/etc/mysql/conf.d/和/etc/mysql/mysql.conf.d/下面

• 3.进入/etc/mysql/conf.d/，修改docker.cnf

  [mysqld]
  skip-host-cache
  skip-name-resolve
  character_set_server=UTF8MB4
  
  

• 4.修改mysql.cnf

[mysql]
default-character-set=UTF8MB4

[mysql.server]
default-character-set=UTF8MB4

[mysql_safe]
default-character-set=UTF8MB4

[client]
default-character-set=UTF8MB4

• 5.进入/etc/mysql/mysql.conf.d/,修改mysqld.cnf

[mysqld]

pid-file	= /var/run/mysqld/mysqld.pid
socket		= /var/run/mysqld/mysqld.sock
datadir		= /var/lib/mysql
#log-error	= /var/log/mysql/error.log
# By default we only accept connections from localhost
#bind-address	= 127.0.0.1
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
character_set_server=UTF8MB4
init_connect='SET NAMES utf8'

[mysql]
default-character-set = UTF8MB4

[mysql.server]
default-character-set = UTF8MB4

[mysqld_safe]
default-character-set = UTF8MB4

[client]
default-character-set = UTF8MB4

• 6.重启容器
• 7.进入mysql命令行输入:show variables like ‘char%’;
