创建映射挂载卷目录

[root@rzk mysql8]# pwd

/opt/mysql8

[root@rzk mysql8]# mkdir conf

[root@rzk mysql8]# mkdir logs

[root@rzk mysql8]# mkdir data


docker 部署mysql8.0_docker


在conf目录新建my.cnf

[mysqld]
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
datadir = /var/lib/mysql
secure-file-priv= NULL
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
character-set-server=utf8
[client]
default-character-set=utf8
[mysql]
default-character-set=utf8
# Custom config should go here
!includedir /etc/mysql/conf.d/

运行容器

docker run --restart=always  \
-v /opt/mysql8/conf/my.cnf:/etc/mysql/my.cnf \
-v /opt/mysql8/logs:/logs \
-v /opt/mysql8/data/:/var/lib/mysql \
-p 3310:3306 \
--name mysql8 \
-d mysql:8.0 \
-e MYSQL_ROOT_PASSWORD='123123' \
--privileged=true \
--character-set-server=utf8mb4

参数解析

参数

含义

--restart=always

当 Docker 重启时,容器自动启动

--name

起别名

-p 3306:3306

映射端口

-v

目录挂载

d mysql:8.0

指定运行版本

-e MYSQL_ROOT_PASSWORD=‘密码’

设置root用户密码

--privileged=true

赋予系统root权限

--character-set-server=utf8mb4

设置字符集为utf8mb4

操作步骤

(一)、新建文件

[root@rzk mysql8]# pwd
/opt/mysql8
[root@rzk mysql8]# mkdir conf
[root@rzk mysql8]# mkdir logs
[root@rzk mysql8]# mkdir data

(二)、拉取mysql8.0镜像

[root@rzk ~]# docker pull mysql:8.0

8.0: Pulling from library/mysql
72a69066d2fe: Pulling fs layer
93619dbc5b36: Pulling fs layer

Status: Downloaded newer image for mysql:8.0
docker.io/library/mysql:8.0

(三)、在conf目录新建my.cnf

[mysqld]
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
datadir = /var/lib/mysql
secure-file-priv= NULL
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
character-set-server=utf8
[client]
default-character-set=utf8
[mysql]
default-character-set=utf8
# Custom config should go here
!includedir /etc/mysql/conf.d/

(四)、在conf目录新建my.cnf

docker run --restart=always -d  \
-v /opt/mysql8/conf/my.cnf:/etc/mysql/my.cnf \
-v /opt/mysql8/logs:/logs \
-v /opt/mysql8/data:/var/lib/mysql \
-p 3310:3306 \
--name mysql8 \
-e MYSQL_ROOT_PASSWORD='123123' \
--privileged=true --restart unless-stopped mysql:8.0 \
--character-set-server=utf8mb4

(五)、验证mysql版本

获取容器名

[root@rzk ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
8082f1 mysql:8.0 " t.s…" ago hours 33060/tcp 06>3306/tcp mysql8

docker 部署mysql8.0_docker_02


进入容器内部查看mysql版本

[root@rzk ~]# docker exec -it 808 bash
root@8082f19b024b:/#

docker 部署mysql8.0_docker_03

输入mysql -uroot -p ,输入部署的密码即可,8.0.29这是最新的8版本

root@8082f19b024b:/# mysql -uroot -p
Enter password:
root@8082f19b024b:/# mysql -uroot -p
Enter password:

修改密码

使用select user,plugin from user where user='root'; 查看加密方式

1、...  mysql;

2、ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '密码';

3、update user set host='%' where user='root';

4、flush privileges;

上面的语句执行后,服务器记得开启外网端口,使用数据库软件进行连接


使用数据库软件进行连接
