docker MySQL数据同步
思诚代码块 人气:0大家好,今天分享一下docker的一个实战
我们使用docker 实现MySQL 的数据同步

拉取mysql 镜像 (我们在这里指定5.7这个版本)
[root@localhost ~]# docker pull mysql:5.7 5.7: Pulling from library/mysql 72a69066d2fe: Pull complete 93619dbc5b36: Pull complete 99da31dd6142: Pull complete 626033c43d70: Pull complete 37d5d7efb64e: Pull complete ac563158d721: Pull complete d2ba16033dad: Pull complete 0ceb82207cd7: Pull complete 37f2405cae96: Pull complete e2482e017e53: Pull complete 70deed891d42: Pull complete Digest: sha256:f2ad209efe9c67104167fc609cca6973c8422939491c9345270175a300419f94 Status: Downloaded newer image for mysql:5.7 docker.io/library/mysql:5.7 [root@localhost ~]#
查看本地镜像

运行一下mysql 容器,做内外网的端口映射,做容器与Linux 主机上的挂载 ,然后给它设密码123456 ,后面加上操作的镜像名
[root@localhost ~]# docker run -d -p 3310:3306 -v /home/mysql/conf:/etc/mysql/conf.d -v /home/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 --name mysql01 mysql:5.7 f3248538d690f67fa057b0b9e00dd060b1ce40378171de0a9f3d9ebd478111d2 [root@localhost ~]#
显示mysql 容器正在运行中
[root@localhost ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES f3248538d690 mysql:5.7 "docker-entrypoint.s…" 4 minutes ago Up 4 minutes 33060/tcp, 0.0.0.0:3310->3306/tcp, :::3310->3306/tcp mysql01 6d6fa6a4c6d7 5d0da3dc9764 "/bin/bash" 25 hours ago Up 25 hours nice_panini [root@localhost ~]#
使用数据库管理工具sql yog 连接我们的数据库
查看服务器ip地址
[root@localhost ~]# ifconfig ens33 ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.1.12 netmask 255.255.255.0 broadcast 192.168.1.255 inet6 fe80::617f:ef93:80d4:e14e prefixlen 64 scopeid 0x20<link> ether 00:0c:29:87:af:a6 txqueuelen 1000 (Ethernet) RX packets 2460532 bytes 2826366757 (2.6 GiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 1198876 bytes 243212283 (231.9 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 [root@localhost ~]#
这里,
命名为容器,
地址:192.168.1.12 (服务器IP地址)
密码:123456 (我们刚才在docker mysql 容器当中设置的密码)
端口:3310 (这是我们刚才做的端口)
连接成功:
就是说,我们使用现在已经可以通过使用数据库管理工具sql yog 连接与使用我们的数据库
这个效果和实际本质与我们平时使用的数据库是一样的
在Linux主机上查看/home 下的文件 (注意,多了一个mysql)
[root@localhost ~]# cd /home/ [root@localhost home]# ls 456.txt admin ceshi daqing mysql zhangsan [root@localhost home]#
映射的配置文件与数据文件
[root@localhost home]# cd mysql/ [root@localhost mysql]# ls conf data [root@localhost mysql]#
这就是我们的数据文件
[root@localhost mysql]# cd data/ [root@localhost data]# ls auto.cnf ca.pem client-key.pem ibdata1 ib_logfile1 mysql private_key.pem server-cert.pem sys ca-key.pem client-cert.pem ib_buffer_pool ib_logfile0 ibtmp1 performance_schema public_key.pem server-key.pem [root@localhost data]#
正式连接数据库 (192.168.1.12)
在我们MySQL中加一个库
在Linux上 ,在映射目录的数据文件多了一个帅哥
[root@localhost data]# ls auto.cnf ca.pem client-key.pem ibdata1 ib_logfile1 mysql private_key.pem server-cert.pem shuaige ca-key.pem client-cert.pem ib_buffer_pool ib_logfile0 ibtmp1 performance_schema public_key.pem server-key.pem sys [root@localhost data]#
删除mysql这个容器
[root@localhost data]# docker rm -f mysql01 mysql01 [root@localhost data]#
映射的数据文件还在,
[root@localhost data]# ls auto.cnf ca.pem client-key.pem ibdata1 ib_logfile1 mysql private_key.pem server-cert.pem shuaige ca-key.pem client-cert.pem ib_buffer_pool ib_logfile0 ibtmp1 performance_schema public_key.pem server-key.pem sys [root@localhost data]#
即,在mysql容器删除之后,数据没有丢失,实现了持久化
这就是docker 容器数据卷的好处
