5. Quickly build LNMP website platform

Quickly deploy LNMP website platform 1, customize network docker network create lnmp2, create Mysql container docker run-d\-name lnmp_mysql\-- net lnmp\-- mount src=mysql-vol,dst=/var/lib/mysql\-e MYSQL_ROOT_PASSWORD=123456-e MYSQL_DATABASE=wordpress mysql:5.7-- character-set-server=utf8 3, create PHP container docker run-d-name lnmp_php-- net lnmp-- mount src=wwwroot

Actual combat exercise:
