Docker——Mysql部署

通过docker容器化部署mysql

1.部署mysql

（1）执行命令部署mysql

docker run -v /home/mysql/:/var/lib/mysql \
-p 3306:3306 -e MYSQL_ROOT_PASSWORD=rootadmin \
--restart=always --name mysql -d mysql

执行成功的情况如下

[root@node1 ~]# docker run -v /home/mysql/:/var/lib/mysql \
> -p 3306:3306 -e MYSQL_ROOT_PASSWORD=rootadmin \
> --restart=always --name mysql -d mysql

备注：
（1）数据库文件直接挂载到服务器的 /home/mysql/ 目录下
（2）端口号使用默认的3306，root密码是 rootadmin

2.检查执行情况

执行 ls /home/mysql 命令，查看 /home/mysql/ 目录的数据库文件

[root@node1 ~]# ls /home/mysql
auto.cnf       binlog.index  client-cert.pem    #ib_16384_1.dblwr  ib_logfile0  #innodb_temp  performance_schema  server-cert.pem  undo_001
binlog.000001  ca-key.pem    client-key.pem     ib_buffer_pool     ib_logfile1  mysql         private_key.pem     server-key.pem   undo_002
binlog.000002  ca.pem        #ib_16384_0.dblwr  ibdata1            ibtmp1       mysql.ibd     public_key.pem      sys

备注：如上图内容所显示则为挂载成功

3.使用mysql

（1）查找mysql具体docker容器

[root@node1 ~]# docker ps | grep mysql
2e0e6049e41b   mysql  "docker-entrypoint.s…"   12 hours ago   Up 12 hours   0.0.0.0:3306->3306/tcp, :::3306->3306/tcp, 33060/tcp   mysql

（2）进入容器内部

[root@node1 ~]# docker exec -it 2e0e6049e41b bash
root@2e0e6049e41b:/#

（3）执行mysql登录和查询命令

root@2e0e6049e41b:/# mysql -uroot -p
