Install nginx and php in docker ubuntu container

Docker can be used to install nginx and php5 (php-mpm) in a ubuntu container. We’ll cover docker running on Mac and Ubuntu Linux for the purpose of this tutorial. The steps are mostly same for both environments.

Download ubuntu image and run it. We’ll use -p 8081:80 when running docker container to make its port 80 available on host port 8081.
```
$ docker pull ubuntu
$ docker run -it -p 8081:80 --name nginxphp1 ubuntu /bin/bash
docker
```

Install nginx and php5-fpm (in docker)

$ apt-get update
$ apt-get upgrade
$ apt-get install nginx
$ apt-get install php5-fpm
$ service nginx start
$ service php5-fpm start

Extra step for Mac. Find docker host IP for mac as it is not localhost for Mac.
```
$ docker-machine ip default
192.168.99.100
```
Note that for Mac, instead of localhost, we’ll use this ip.
Check if ngnix is working by visiting localhost:8081 (or docker_host_ip:8081 for Mac) in browser and you should be able to see nginx default page.

Edit default site settings in /etc/nginx/sites-available/default and uncomment php settings. It should look like this.

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        location ~ \.php$ {
                fastcgi_split_path_info ^(.+\.php)(/.+)$;
                # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
        
                # With php5-cgi alone:
                # fastcgi_pass 127.0.0.1:9000;
                # With php5-fpm:
                fastcgi_pass unix:/var/run/php5-fpm.sock;
                fastcgi_index index.php;
                include fastcgi_params;
        }

Note that we have kept fastcgi_pass commented out.

Now restart nginx

$ service nginx restart

Now edit /etc/php5/fpm/php.ini and
add cgi.fix_pathinfo = 0 in relevant section. Then restart php5-fpm
```
$ service php5-fpm restart
 * Restarting PHP5 FastCGI Process Manager php5-fpm
```

Start service nginx and php5-fpm

service nginx start

service php5-fpm start

Create file info.php in directory /usr/share/nginx/html/ with the following content:
```
<?php
  phpinfo();
?>
```
Now visit localhost:8081/info.php (or docker_host_ip:8081/info.php for Mac) and you should be able to see php info page.
