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 /work/mysql/:/var/lib/mysql \
-p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 \
--restart=always --name mysql -d mysql
执行成功的情况如下
[root@node1 ~]# docker run -v /work/mysql/:/var/lib/mysql \
> -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 \
> --restart=always --name mysql -d mysql

备注：
（1）数据库文件直接挂载到服务器的 /work/mysql/ 目录下
（2）端口号使用默认的3306，root密码是 123456
2.检查执行情况
执行 ls /work/mysql 命令，查看 /work/mysql/ 目录的数据库文件
[root@node1 ~]# ls /work/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
