因为须要修改mysql的sql_mode，在命令行修改每次重启都会失效，由于修改docker下mysql的配置文件。css

操做系统：centos7 
docker版本：Docker version 17.05.0-ce, build 89658be 
mysql版本：5.7.18mysql

1.拉取镜像sql

docker pull mysql:5.7.18

2.列出镜像docker

[root@zk01 ~]# docker images
REPOSITORY                                                   TAG                 IMAGE ID            CREATED             SIZE
mysql                                                        5.7.18              e799c7f9ae9c        5 weeks ago         407MB

3.运行dockercentos

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ruby

[root@zk01 docker]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
e1066fe2db35        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bash

docker exec -it e1066fe2db35 /bin/bash

6.查看配置文件app

/etc/mysql/mysql.conf.d/mysqld.cnf

配置文件内容：socket

[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

7.查看mysql的sql_modetcp

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.中止并删除容器

docker stop e1066fe2db35
docker rm e1066fe2db35

9.从新启动容器，指定数据目录和配置文件

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

mysql> SELECT @@GLOBAL.sql_mode; +-------------------+
| @@GLOBAL.sql_mode | +-------------------+
| | +-------------------+
1 row in set

mysql> SELECT @@SESSION.sql_mode; +--------------------+
| @@SESSION.sql_mode | +--------------------+
| | +--------------------+
1 row in set
