这篇文章主要介绍docker中如何安装mysql,文中介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们一定要看完!
1、docker hub上面查找mysql镜像
[root@t-docker tomcatlogs]# docker search mysql NAME DESCRIPTION STARS OFFICIAL AUTOMATED mysql MySQL is a widely used, open-source relation… 6845 [OK] mariadb MariaDB is a community-developed fork of MyS… 2185 [OK] mysql/mysql-server Optimized MySQL Server Docker images. Create… 502 [OK] percona Percona Server is a fork of the MySQL relati… 365 [OK] zabbix/zabbix-server-mysql Zabbix Server with MySQL database support 120
2、从docker hub上(或阿里云加速器)拉取mysql镜像到本地
[root@t-docker tomcatlogs]# docker pull mysql:5.6 5.6: Pulling from library/mysql be8881be8156: Already exists c3995dabd1d7: Pulling fs layer 9931fdda3586: Pulling fs layer bb1b6b6eff6a: Pulling fs layer a65f125fa718: Pulling fs layer 62fa8db7a5dc: Pulling fs layer a65f125fa718: Waiting 0f5681d76128: Pull complete 56d3348c5742: Pull complete b93f67de42c4: Pull complete 5adba6c10127: Pull complete Digest: sha256:2e48836690b8416e4890c369aa174fc1f73c125363d94d99cfd08115f4513ec9 Status: Downloaded newer image for mysql:5.6
[root@t-docker tomcatlogs]# docker images mysql REPOSITORY TAG IMAGE ID CREATED SIZE mysql 5.6 7edb93321b06 4 weeks ago 256MB
3、使用mysql镜像创建容器(也叫运行镜像)
[root@t-docker chenzx]# docker run -p 12345:3306 --name mysql -v /volume/mysql/conf:/etc/mysql/conf.d -v /volume/mysql/logs:/logs -v /volume/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.6
命令说明:
-p 12345:3306:将主机的12345端口映射到docker容器的3306端口;
--name mysql:运行容器的名字
-v 挂载宿主机上的数据卷到容器里面
-e MYSQL_ROOT_PASSWORD=123456:初始化root的密码
-d mysql:5.6:后台运行mysql5.6
[root@t-docker chenzx]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 6dc80df5e339 mysql:5.6 "docker-entrypoint.s…" About a minute ago Up About a minute 0.0.0.0:12345->3306/tcp mysql
[root@t-docker chenzx]# docker exec -it 6dc80df5e339 /bin/bash root@6dc80df5e339:/# mysql -uroot -p123456 Warning: Using a password on the command line interface can be insecure.

4、备份docker容器里面的MySQL
[root@t-docker chenzx]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 6dc80df5e339 mysql:5.6 "docker-entrypoint.s…" 16 minutes ago Up 16 minutes 0.0.0.0:12345->3306/tcp mysql
[root@t-docker chenzx]# docker exec 6dc80df5e339 sh -c 'exec mysqldump -uroot -p123456 -B mysql' > mysql.sql
