CentOS中开启mysql挂载

挂载的作用其实说白了就是备份。防止数据库文件损害或者数据库被误删导致数据丢失。

创建一个文件名为my.cnf内容如下

[mysqld]
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
datadir         = /var/lib/mysql
secure-file-priv= NULL
default_authentication_plugin=mysql_native_password

# Custom config should go here
!includedir /etc/mysql/conf.d/

server-id=200

如果已经安装了mysql需要对mysql容器进行卸载。

卸载后在自己准备保存挂载数据的地方创建目录结构如下，并将my.cnf放置到conf文件夹中

创建好之后重安装mysql的容器

创建一个名为mysql的容器，并且配置相关信息。把自己的目录位置替换到下面的我的目录位置中

docker run -it \
--name mysql \
-p 3306:3306 \
--privileged \
-e MYSQL_ROOT_PASSWORD=123 \
-v /etc/localtime:/etc/localtime \
-v /usr/local/software/mysql/3306/conf/my.cnf:/etc/mysql/my.cnf \
-v /usr/local/software/mysql/3306/data:/var/lib/mysql \
-v /usr/local/software/mysql/3306/mysql-files:/var/lib/mysql-files \
-d mysql
