创建容器

docker run -d -p 3306:3306 --name mysql5.7 \--privileged \-v /opt/docker_mysql5.7/log:/var/log/mysql \-v /opt/docker_mysql5.7/data:/var/data/mysql \-v /opt/docker_mysql5.7/conf:/etc/mysql \-e MYSQL_ROOT_PASSWORD='123456' \mysql:5.7

MySQL默认sock的目录在/var/lib/mysql

使用连接mysql端口的方式备份

xtrabackup --backup   --user=root   --password='123456'   --host=127.0.0.1   --port=3306   --parallel=3   --target-dir=/data/mysqlbackups/
