启动mysql
sudo docker run -p 3306:3306 --name mysql \ -v /mydata/mysql/log:/var/log/mysql \ -v /mydata/mysql/data:/var/lib/mysql \ -v /mydata/mysql/conf:/etc/mysql \ -e MYSQL_ROOT_PASSWORD=root \ -d mysql:5.7
修改配置
[root@hadoop-104 conf]# pwd /mydata/mysql/conf [root@hadoop-104 conf]# cat my.cnf [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 skip-name-resolve [root@hadoop-104 conf]# [root@hadoop-104 conf]# docker restart mysql mysql [root@hadoop-104 conf]#
进入容器查看配置：
[root@hadoop-104 conf]# docker exec -it mysql /bin/bash root@b3a74e031bd7:/# whereis mysql mysql: /usr/bin/mysql /usr/lib/mysql /etc/mysql /usr/share/mysql root@b3a74e031bd7:/# ls /etc/mysql my.cnf root@b3a74e031bd7:/# cat /etc/mysql/my.cnf [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 skip-name-resolve root@b3a74e031bd7:/#
