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

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

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

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

进入容器内部查看mysql版本

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

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、use 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
