docker mysql配置文件 docker下修改mysql配置文件的方法

vrix 人气:0

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

docker pull mysql:5.7.18

2.列出镜像

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

3.运行docker

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

[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

docker exec -it e1066fe2db35 /bin/bash

6.查看配置文件

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

配置文件内容:

[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.查看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.停止并删除容器

docker stop e1066fe2db35
docker rm e1066fe2db35

9.重新启动容器,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
