Docker: Build Lamp Application

LAMP refers to the Linux (operating system), Apachehttp Server, MySQL (sometimes referred to as MARIADB, database software) and PHP (sometimes referred to as Perl or Python) The first letter, generally used to build a Web server. Although these open source programs are not specifically designed to work with several other programs, this combination has become popular because of their free and open source (most Linux distributions are bundled with these software). When used together, they act like a dynamic solution package. Here's how to use Docker to build a container containing lamp components: pull a lamp mirror from the web

There is no mirror image of the official lamp in the official warehouse, but the "tutum" mirror is doing very well and we can pull their mirrors directly to complete our operation.

Core@localhost ~/base $ docker Pull Tutum/lamp pulling repository tutum/lamp 4b32789c7d66:download complete
...

Start the lamp container using the default method

Core@localhost ~/base $ docker run-d-P 8080:80-p 3306:3306 tutum/lamp #启动应用并映射 8080 ports and 3306 ports 0ee00c97a5cdefb985baf82                              6C16723F333AA5EDDDEE4072A5107C724AD09F10D core@localhost ~/base $ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAM ES 0ee00c97a5cd tutum/lamp:latest "/run.sh" 3 seconds ago up 2 seconds 0                   .0.0.0:3306->3306/tcp, 0.0.0.0:8080->80/tcp Lonely_davinci e3c136d76b44 tutum/tomcat:8.0

The default container launches a Helloword application, and we can use Dockerfile to create another mirror to deploy our own application, Dockerfile detailed syntax will be described later in this chapter.

Core@localhost ~ $ mkdir php
core@localhost ~ $ cd php/
core@localhost ~/php $ touch dockerfile
core@localhost ~/php $ VI dockerfile
core@localhost ~/php $ docker build-t Dockerpool/my-lamp-app.
 
Dockerfile contents are as follows:

From Tutum/lamp:latest
RUN rm-fr/app && git clone https://github.com/username/customapp.git/app
# Here replace the Https://github.com/username/customapp.git address for your own project address
expose 3306
CMD ["/run.sh"]
 
Start your own container again and complete the deployment

Core@localhost ~/php $ docker Stop    0ee
0ee
core@localhost ~/php $ docker rm 0ee
0ee
Core@localhost ~/php $ docker run-d-P 8080:80-p 3306:3306 Dockerpool/my-lamp-app
 
Use Curl to see if your application has started correctly!

Curl http://localhost/
Connect the database in the PHP program to access the MySQL database in the container
This mirrored MySQL database has a default root user, which can be used without a password when connected locally, so it is very easy to access the code.

<?php
$mysql = new mysqli ("localhost", "root");
echo "MySQL Server Info:". $mysql->host_info;
? >
Accessing the MySQL database outside the container
When we first start the container in Tutum/lamp mirroring, it automatically creates a MySQL user named admin and generates a random password, which can be obtained using the "docker logs + container id".

Core@localhost ~/php $ docker logs 9CB
=> an empty or uninitialized MySQL volume is detected in/var/lib/mysql
=> Installing MySQL ...
=> done!
=> waiting for confirmation to MySQL service startup
=> creating MySQL Admin user with random password
=> done!
========================================================================
can now connect to this MySQL Server  Using:

    mysql-uadmin-p2ijg6gvmm0n3-h
 
The default root user cannot log on remotely, so it also has root permissions to use the Admin user.
