A detailed tutorial on how to install Linux Docker

Install the mysql service

Download mysql image:

docker pull mysql

Create the mysql container and run it in the background, specifying the database password 123456. -e specifies environment variables.

docker run --name mysql_db -e MYSQL_ROOT_PASSWORD=123456 -d mysql

Use the official wordpress

wordpress mirror daocloud.io:

docker pull daocloud.io/daocloud/dao-wordpress:latest

Please login before pulling image: docker login daocloud.io (login with user name).

Or use the wordpress official image:

docker pull wordpress

Create the wordpress container application and run it in the background:

docker run --name some-wordpress --link mysql_db:mysql -p 8001:80 -d daocloud.io/daocloud/dao-wordpress

You can then access the site from your browser via http://localhost:8001 (or http:// host-ip :8001).

If you want to use an external database, you can set the connection mode of the corresponding database through the above environment variables:

$ docker run --name some-wordpress -e WORDPRESS_DB_HOST=10.1.2.3:3306 \
  -e WORDPRESS_DB_USER=... -e WORDPRESS_DB_PASSWORD=... -d wordpress

More environmental variables:

WORDPRESS_DB_HOST database host address (default is IP and port 3306 of its link mysql container: :3306)
WORDPRESS_DB_USER database user name (root by default)
WORDPRESS_DB_PASSWORD database password (default is the value of the MYSQL_ROOT_PASSWORD variable supplied by its link mysql container)
WORDPRESS_DB_NAME database name (wordpress by default)
WORDPRESS_TABLE_PREFIX database table name prefix (default is empty, you can override the configuration in wp-config.php from this variable)

Security correlation (default is random SHA1)

WORDPRESS_AUTH_KEY
WORDPRESS_SECURE_AUTH_KEY
WORDPRESS_LOGGED_IN_KEY
WORDPRESS_NONCE_KEY
WORDPRESS_AUTH_SALT
WORDPRESS_SECURE_AUTH_SALT
WORDPRESS_LOGGED_IN_SALT
WORDPRESS_NONCE_SALT

If the database specified by the WORDPRESS_DB_NAME variable does not exist, then the wordpress container will automatically attempt to create the database at startup, but the user specified by the WORDPRESS_DB_USER variable will need the permission to create the database.

Choreographed using Fig

Fig is the application orchestration tool of Docker, which is mainly used to build complex applications based on Docker together with Docker 1. Fig manages multiple Docker containers through one configuration file, which is very suitable for the scenario of combining multiple containers for development. Currently, Fig has been upgraded and renamed Compose. Compose backwards compatible with Fig.

The Docker application management is made easier and faster by the application orchestration tool. Fig website: http: / / www fig. sh /

Install Fig:

#  methods 1 : 
curl -L https://github.com/docker/fig/releases/download/1.0.1/fig-`uname 
-s`-`uname -m` > /usr/local/bin/fig; chmod +x /usr/local/bin/fig
#  methods 2 : 
yum install python-pip python-dev
pip install -U fig

Write fig. yml:

wordpress:
 image: daocloud.io/daocloud/dao-wordpress:latest
 links:
  - db:mysql
 ports:
  - "8002:80"
db:
 image: mysql
 environment:
  - MYSQL_ROOT_PASSWORD=123456
 Deployment application: 
#  Start the 
fig up
#  Get up and running in the background 
fig up -d

You can then access the site from your browser via http://localhost:8002 (or http:// host-ip :8002).

Use the network

wordpress:
 image: daocloud.io/daocloud/dao-wordpress:latest
 environment:
  - WORDPRESS_DB_HOST=119.119.192.246:3306
  - WORDPRESS_DB_USER=root
  - WORDPRESS_DB_PASSWORD=123456
 ports:
  - "80"

Fig command:

docker run --name mysql_db -e MYSQL_ROOT_PASSWORD=123456 -d mysql

0

Note: fig has been upgraded to compose: https: / / github com/docker/compose

The batch

docker run --name mysql_db -e MYSQL_ROOT_PASSWORD=123456 -d mysql
