Quickly build a PHP development environment with Docker link

In general, we will install Nginx, PHP are installed in the same container, in order to expand convenience, we hope that nginx container and PHP container separate. Then you can use the Docker link command to do this.

Required Image:

• Nginx 1.12.2
• PHP (including php-fpm7.1) 7.1

Here the Nginx image selection daocloud.io/library/nginx:1.12.2-alpine , PHP image compiled by itself (the selection is Https://github.com/52fhy/docker-images php56-fpm-centos68-withext and php71-fpm-centos68-phalcon-withext ).

Practice

Run PHP-FPM:

docker run -d --restart=always --name yphp      -v /work/:/work/       "/work/yphp/php/etc/":/usr/local/php/etc/       php71-fpm-centos68-phalcon-withext

--restart=alwaysEnables the container to boot with the Docker service itself. -vSpecifies the directory mapping relationship for the host and container.

This is /work/yphp from https://github.com/52fhy/yphp.

/workSubdirectories included in the contents:

/work  |-- www  |---yphp

/wwwis the project directory, yphp is the Nginx and PHP configuration directory, mapped to the container, convenient for local modification.

Run Nginx:

docker run -d --restart=always --name some-nginx -p 80:80 --link yphp:yphp      -v /work/:/work/      -v /work/yphp/nginx/conf/:/etc/nginx/      -v /work/yphp/nginx/logs/:/etc/nginx/logs/      daocloud.io/library/nginx:1.12.2-alpine

It nginx:1.12.2-alpine is chosen because the image is very small.

Commands are not many, but there are a lot of things to watch out for, which may cause the service to be unhealthy:

1, for PHP-FPM container, php-fpm www.conf configuration file, the IP of the monitoring can not be 127.0.0.1, must be 0.0.0.0; This will cause the subsequent nginx to appear 404 (see the problem).

;listen = 127.0.0.1:9000listen = 0.0.0.0:9000

2, the Nginx container must be --link connected to the PHP-FPM container.
3. The WWW directory of the Nginx container and the PHP-FPM container must be consistent.
4, Nginx container configuration Fastcgi_pass need to modify the --link name (the actual host name, will be in the Nginx container /etc/hosts added a host record).
5, if the Nginx container needs to support more port access, then use -p the scope representation, example: -p 80-90:80-90 . Or more than one -p parameter.
6, the -v parameter specifies the local mount directory (in the example /work ) subdirectory (for example /www ) in the host cannot be a soft link, otherwise it will cause nginx 404, because the soft link in the container is invalid. But /work it can be a soft link itself.

Nginx Configuration:
Hello.cc.conf

server {    listen       80;    server_name  hello.cc;    access_log  logs/access.log;    error_log  logs/error.log;    root /work/yphp/php/;    index  index.php index.html index.htm;    location ~ \.php$ {                #fastcgi_pass   127.0.0.1:9000;        fastcgi_pass   yphp:9000;        fastcgi_index  index.php;        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;        include        fastcgi_params;    }}

Notice that the fastcgi_pass changes have been made here.

Run multiple versions of PHP

docker run -d --restart=always --name yphp56  -p 9000:9000      -v /work/:/work/       "/work/yphp/php/etc56/":/usr/local/php/etc/       php56-fpm-centos68-withext     docker run -d --restart=always --name yphp  -p 9001:9000      -v /work/:/work/       "/work/yphp/php/etc/":/usr/local/php/etc/       php71-fpm-centos68-phalcon-withextdocker run -d --restart=always --name some-nginx -p 80-90:80-90 --link yphp56 --link yphp      -v /work/:/work/      -v /work/yphp/nginx/conf/:/etc/nginx/      -v /work/yphp/nginx/logs/:/etc/nginx/logs/      daocloud.io/library/nginx:1.12.2-alpine

For --link the Nginx container used, the parameters of the PHP-FPM container -p do not actually produce a function, can omit to write.

This is the /work same directory for the host.

docker pswhether the view state is used is UP :

$ docker psCONTAINER ID        IMAGE                                     COMMAND                  CREATED             STATUS              PORTS                            NAMES221c6ffb19dd        daocloud.io/library/nginx:1.12.2-alpine   "nginx -g 'daemon of…"   12 minutes ago      Up 2 seconds        0.0.0.0:80-90->80-90/tcp         some-nginx02a4f9d804f7        php71-fpm-centos68-phalcon-withext        "/run.sh"                24 minutes ago      Up 3 seconds        80/tcp, 0.0.0.0:9001->9000/tcp   yphpa9decc06558e        php56-fpm-centos68-withext                "/run.sh"                25 minutes ago      Up 3 seconds        80/tcp, 0.0.0.0:9000->9000/tcp   yphp56

The description is normal.

If your Mac or Linux is installed locally and you have Docker (not toolbox), 127.0.0.1 you can see that Nginx is already running. 127.0.0.1 hello.cc /etc/hosts After you add to (non-Windows) Access http://hello.cc/you can see the phpinfo information. Try to modify /work/yphp/nginx/conf/vhost/hello.cc.conf the port in the fastcgi_pass 9001, and then restart the Nginx container or restart the Nginx container, you will find that the PHP version shown in Phpinfo becomes PHP7.1.
