2. Custom network, commonly used in production environment, containers created later are added to lnmp network
docker network create lnmp
3. Creating a mysql container
mysql5.7 version is used here, and the parameter--restart always is added to ensure that the container can start automatically when the host is started.
docker run -itd --restart always --name lnmp_mysql --net lnmp -p 3306:3306 --mount src=mysql-vol,dst=/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -e MYSQL_DATABASE=wordpress mysql:5.7 --character-set-server=utf8
The mysql-vol volume is automatically created.
[root@localhost volumes]# pwd
/var/lib/docker/volumes
[root@localhost volumes]# docker volume ls
DRIVER VOLUME NAME
local mysql-vol
local rancher-agent-state
local rancher-cni
local rancher-cni-driver
[root@localhost volumes]# docker volume inspect mysql-vol
[
{
"CreatedAt": "2019-08-18T11:52:35+08:00",
"Driver": "local",
"Labels": null,
"Mountpoint": "/var/lib/docker/volumes/mysql-vol/_data",
"Name": "mysql-vol",
"Options": null,
"Scope": "local"
}
]
Create a volume for example docker volume create nginx-vol
After the container is created, the database wordpress is created
Enter mysql container, docker exec -it lnmp_mysql /bin/bash
Enter database mysql -uroot -p123456
Create a regular user
grant all on wordpress.* to wordpress@'%' identified by '123456';
flush privileges;
mysql> select user,host from mysql.user;
+---------------+-----------+
| user | host |
+---------------+-----------+
| root | % |
| wordpress | % |
| mysql.session | localhost |
| mysql.sys | localhost |
| root | localhost |
+---------------+-----------+
5 rows in set (0.01 sec)
mysql>
docker exec lnmp_mysql bash -c 'exec mysql -uroot -p123456 -e "grant all on wordpress.* to wordpress@'%' identified by '123456';"'

docker run -itd --restart always --name lnmp_web --net lnmp -p 88:80 --mount type=bind,src=/lnmp/web,dst=/var/www/html richarvey/nginx-php-fpm
Create the/lnmp/web directory locally and mount the directory to the container for data persistence.
