由于需要修改mysql的sql_mode，在命令行修改每次重启都会失效，因为修改docker下mysql的配置文件。
操作系统：centos7
docker版本：Docker version 17.05.0-ce, build 89658be
mysql版本：5.7.18
1.拉取镜像
1 | docker pull mysql:5.7.18 |
2.列出镜像
1 2 3 | [root@zk01 ~]# docker imagesREPOSITORY TAG IMAGE ID CREATED SIZEmysql 5.7.18 e799c7f9ae9c 5 weeks ago 407MB |
3.运行docker
1 | docker run -d -p 3306:3306 --name mymysql -e MYSQL_ROOT_PASSWORD=123456 mysql:5.7.18 |
4.列出正在运行的容器
1 2 3 | [root@zk01 docker]# docker psCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESe1066fe2db35 mysql:5.7.18 "docker-entrypoint..." 6 seconds ago Up 6 seconds 0.0.0.0:3306->3306/tcp mymysql |
5.进入容器
1 | docker exec -it e1066fe2db35 /bin/bash |
6.查看配置文件
1 | /etc/mysql/mysql.conf.d/mysqld.cnf |
配置文件内容：
1 2 3 4 5 6 7 8 9 | [mysqld]pid-file = /var/run/mysqld/mysqld.pidsocket = /var/run/mysqld/mysqld.sockdatadir = /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 |
7.查看mysql的sql_mode
1 2 3 4 5 6 7 | mysql> SELECT @@GLOBAL.sql_mode;+-------------------------------------------------------------------------------------------------------------------------------------------+| @@GLOBAL.sql_mode |+-------------------------------------------------------------------------------------------------------------------------------------------+| ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION |+-------------------------------------------------------------------------------------------------------------------------------------------+1 row in set |
8.停止并删除容器
1 2 | docker stop e1066fe2db35docker rm e1066fe2db35 |
9.重新启动容器，指定数据目录和配置文件
1 | docker run -d -p 3306:3306 -v /soft/mysql/my.cnf:/etc/mysql/mysql.conf.d/mysqld.cnf -v /soft/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 --name mymysql mysql:5.7.18 |
10.查看sql_mode
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | mysql> SELECT @@GLOBAL.sql_mode;+-------------------+| @@GLOBAL.sql_mode |+-------------------+| |+-------------------+1 row in setmysql> SELECT @@SESSION.sql_mode;+--------------------+| @@SESSION.sql_mode |+--------------------+| |+--------------------+1 row in set |
