docker 部署mysql8.0

Posted 2022-07-02 有过～

这个平台第一篇博客记录下,哈哈哈哈

有一说一,这些文档还挺不错的

拉去mysql镜像

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

Status: Downloaded newer image for mysql:8.0

docker.io/library/mysql:8.0

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

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 
99da31dd6142: Pulling fs layer 
626033c43d70: Pull complete 
37d5d7efb64e: Pull complete 
ac563158d721: Pull complete 
d2ba16033dad: Pull complete 
688ba7d5c01a: Pull complete 
00e060b6d11d: Pull complete 
1c04857f594f: Pull complete 
4d7cfa90e6ea: Pull complete 
e0431212d27d: Pull complete 
Digest: sha256:e9027fe4d91c0153429607251656806cc784e91493271037f7738bd5b8e7709
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、...  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
