docker安装部署mysql并修改中文配置(mysql5.7)

1.拉取镜像

docker pull mysql:5.7.18

2.查看镜像

docker images

3.运行docker容器

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

4.查看容器是否启动成功

docker ps

5.修改容器随docker启动自启动

docker update --restart=always 容器ID

6.进入容器

docker exec -it 容器ID /bin/bash

7.查看配置

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

**注意：**如果执行该语句提示没有该文件，先看完下面的内容 自行酌情处理

8.编辑配置

8.1方式一：将配置从容器中copy到宿主机，在宿主机编辑完成后copy回容器中

docker cp mysql:/etc/mysql/mysql.conf.d/mysqld.cnf /root/mysqld.cnf

**注意：**如果没有该文件，那这一步省略，直接在宿主机编辑好以下写好的配置再copy放到容器中就好

mysqld.cnf如下：

[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
character_set_server=utf8
init_connect='SET NAMES utf8'
max_allowed_packet = 20M

[mysql]
default-character-set = utf8

[mysql.server]
default-character-set = utf8

[mysqld_safe]
default-character-set = utf8

[client]
default-character-set = utf8

将修改后的配置copy到容器

docker cp /root/mysqld.cnf mysql:/etc/mysql/mysql.conf.d/

**注意：**上述语句mysql为容器name，可用docker ps查看

8.2方式二 直接编辑 容器内的mysqld.cnf，编辑中文编码后重启容器即可

vi /etc/mysql/mysql.conf.d/mysqld.cnf
（内容参考上述配置文件）

9.最后重启容器就可以了

docker restart 容器ID
