docker安装MySQL

写在前面

安装了docker环境 再来看下如何使用docker安装MySQL。

1：下载镜像

[root@localhost ~]# docker pull mysql:8.0
Trying to pull repository docker.io/library/mysql ... 
8.0: Pulling from docker.io/library/mysql
72a69066d2fe: Pull complete 
93619dbc5b36: Pull complete 
...
1c04857f594f: Pull complete 
4d7cfa90e6ea: Pull complete 
e0431212d27d: Pull complete 
Digest: sha256:e9027fe4d91c0153429607251656806cc784e914937271037f7738bd5b8e7709
Status: Downloaded newer image for docker.io/mysql:8.0
[root@localhost ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
docker.io/mysql     8.0                 3218b38490ce        20 months ago       516 MB

2：准备容器使用的本地目录

用于挂载容器数据和配置文件，日志等。

[root@localhost ~]# mkdir -p /usr/local/docker/mydata/mysql/conf
[root@localhost ~]# chmod -R 755  /usr/local/docker/mydata/mysql/

vim /usr/local/docker/mydata/mysql/conf/my.cnf
 
[client]
default-character-set=utf8
[mysql]
default-character-set=utf8
[mysqld]
init_connect='SET collation_connection = utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_unicode_ci
skip-character-set-client-handshake
skip-name-resolve
secure_file_priv=/var/lib/mysql

3：启动容器

[root@localhost ~]# sudo docker run -p 3316:3306 --name mysql \
> -v /usr/local/docker/mydata/mysql/log:/var/log/mysql \
> -v /usr/local/docker/mydata/mysql/data:/var/lib/mysql \
> -v /usr/local/docker/mydata/mysql/conf:/etc/mysql \
> -e MYSQL_ROOT_PASSWORD=root \
> -d mysql:8.0
d939e6aed5778a04efdf613df3afe04e7b79aac47260292094fab603c6e375de

本地的3316端口，映射到容器的3306端口。启动成功后查看容器信息：

[root@localhost ~]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                               NAMES
d939e6aed577        mysql:8.0           "docker-entrypoint..."   3 seconds ago       Up 2 seconds        33060/tcp, 0.0.0.0:3316->3306/tcp   mysql

4：配置容器

[root@localhost ~]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                               NAMES
d939e6aed577        mysql:8.0           "docker-entrypoint..."   3 seconds ago       Up 2 seconds        33060/tcp, 0.0.0.0:3316->3306/tcp   mysql
[root@localhost ~]# docker exec -it mysql ./bin/bash
root@d939e6aed577:/# mysql -uroot -proot
mysql: [Warning] Using a password on the command line interface can be insecure.

5：外部连接MySQL服务器

C:\Users\Administrator>mysql -h 192.168.64.129 -P 3316 -uroot -p
Enter password: ****
