Docker-如何设置mysql容器中字符集

docker的mysql镜像为1.8版本

首先去mysql容器中寻找mysql.cnf文件

通常在以下地址：

[root@iz2zei9wv79ob7vwy7y1jcz tmp]# docker exec -it mysql01 bash
root@e868fadad232:/# ls
bin   dev			  entrypoint.sh  home  lib64  mnt  proc  run   srv  tmp  var
boot  docker-entrypoint-initdb.d  etc		 lib   media  opt  root  sbin  sys  usr
root@e868fadad232:/# cd etc
root@e868fadad232:/etc# cd mysql
root@e868fadad232:/etc/mysql# ls
conf.d	my.cnf	my.cnf.fallback
root@e868fadad232:/etc/mysql# cd conf.d
root@e868fadad232:/etc/mysql/conf.d# ls
docker.cnf  mysql.cnf
root@e868fadad232:/etc/mysql/conf.d# exit

将容器文件cp到物理机随意目录

[root@iz2zei9wv79ob7vwy7y1jcz tmp]# docker cp mysql01:/etc/mysql/conf.d/mysql.cnf  /tmp
[root@iz2zei9wv79ob7vwy7y1jcz tmp]# ls
mysql.cnf

对配置文件进行编辑

[client]
default-character-set=utf8

[mysql]
default-character-set=utf8

[mysqld]
init_connect='SET collation_connection = utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_unicode_ci
skip-character-set-client-handshake

将文件cp会mysql 容器对应位置，并重启容器使配置生效

[root@iz2zei9wv79ob7vwy7y1jcz tmp]# docker cp  /tmp/mysql.cnf  mysql01:/etc/mysql/conf.d/
[root@iz2zei9wv79ob7vwy7y1jcz tmp]# docker restart mysql01
mysql01

登陆mysql 查看对应字符集设置

mysql> show variables like'char%';
