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
搜索mysql 镜像
[root@localhost ~]# docker search mysql

[root@localhost ~]#
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

显示mysql 容器正在运行中
[root@localhost ~]# docker ps

[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

[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
到此这篇关于docker实现MySQL数据同步的方法的文章就介绍到这了,更多相关docker MySQL数据同步内容请搜索编程学习网以前的文章希望大家以后多多支持编程学习网!
