由於需要修改mysql的sql_mode，在命令列修改每次重啟都會失效，因為修改docker下mysql的配置檔案。

作業系統：centos7 
docker版本：Docker version 17.05.0-ce, build 89658be 
mysql版本：5.7.18

1.拉取映象

docker pull mysql:5.7.18

2.列出映象

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

3.執行docker

docker run -d -p 3306:3306 --name mymysql -e MYSQL_ROOT_PASSWORD=123456 mysql:5.7.18

4.列出正在執行的容器

[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.進入容器

docker exec -it e1066fe2db35 /bin/bash
 

6.檢視配置檔案

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

配置檔案內容：

[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.檢視mysql的sql_mode

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.停止並刪除容器

docker stop e1066fe2db35
docker rm e1066fe2db35

9.重新啟動容器，指定資料目錄和配置檔案

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.檢視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
