Docker installs mysql5.7 and starts binlog

install

docker pull mysql:5.7

Create a folder for storing mappings

mkdir -p /mydata/mysql/log
mkdir -p /mydata/mysql/data
mkdir -p /mydata/mysql/conf

function mysql

docker run --name mysql5.7 -e MYSQL_ROOT_PASSWORD=123456 -d -v /mydata/mysql/log:/var/log/mysql -v /mydata/mysql/data:/var/lib/mysql -v /mydata/mysql/conf:/etc/mysql -p 8001:3306 mysql:5.7

Turn on binlog（5.7 Not on by default ,8 Default on ）

Create two new profiles

cd /mydata/mysql/conf
touch my.cnf
touch my.conf

Be careful my.cnf The permission of cannot be opened too large , No, it will be mysql Ignore

chmod 664 that will do , open 777 Will be ignored
