Set up php project with composer on CentOS 7

PHP is the best language. – Annoymous
To be honest, I am still not very sure when some programmer tells me that “PHP is the best language” whether he is serious or just being sarcastic. But anyway since I learned about programming, I did not have a chance of working with PHP seriously and recently I got assigned to set up my company’s forum using a very new Forum system developed on top of PHP – Flarum–therefore I had the chance of working with PHP.
There are quite some incompatible changes in PHP 7 and we can also see the performance boost in the release of PHP 7 comparison. But at the time of my writing, Flarum is only supported on PHP 5.6 and 5.7 so this post will talk about PHP 5.6 installation and setup only.
So tools and languages we need: PHP 5.6, Node.js 4+(5+ OK as well), Nginx 1.6+, MySQL 5.6+. After getting a basic idea of this, let’s start.
CentOS is a great OS but it does not come with a big package repo–so we need to extend to locate our required packages:
wget http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
wget http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
rpm -Uvh remi-release-7*.rpm epel-release-7*.rpm
So the command above will install fedora project’s repo and php’s repo in your system. And for remi, you need to modify repo’s settings to choose which version of PHP you would like to install:
[remi]
name=Les RPM de remi pour Enterprise Linux 6 - $basearch
#baseurl=http://rpms.famillecollet.com/enterprise/6/remi/$basearch/
mirrorlist=http://rpms.famillecollet.com/enterprise/6/remi/mirror
enabled=1 # make sure this is enabled so that remi repos will be queried by CentOS
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi
[remi-php56]
name=Les RPM de remi de PHP 5.6 pour Enterprise Linux 6 - $basearch
#baseurl=http://rpms.famillecollet.com/enterprise/6/php56/$basearch/
mirrorlist=http://rpms.famillecollet.com/enterprise/6/php56/mirror
# WARNING: If you enable this repository, you must also enable "remi"
enabled=1 # and we are using PHP 5.6 in this case
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi
Now, run sudo yum update and sudo yum install nginx php php-cli php-mysql–you should have nginx and php set up already.
Now let’s move to Node.js:
curl --silent --location https://rpm.nodesource.com/setup_4.x | bash -
# for this command, you may want to change it to curl --silent --location https://rpm.nodesource.com/setup_4.x | sudo bash -
# for sudo access
Now you should be able to install Node.js 4+ with sudo yum install nodejs.
Starting from CentOS 7, MariaDB has replaced MySQL in its repo. Although MariaDB is supposed to be able to replace of a lot of MySQL’s functionalities, it is still better to install MySQL(until Oracle starts to charge for MySQL-community?)
wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
sudo rpm -ivh mysql-community-release-el7-5.noarch.rpm
And you install MySQL with sudo yum install mysql-server should do.
In the case of Flarum, there are some development tools such as npm, Gulp and composer needed for managing dependencies and run tasks. Since npm comes with Nodejs and now we need to care about composer and Gulp.
Installing Gulp is very easy since we have npm already. Just run npm install gulp-cli -g to enable command line accesses for gulp globally(anywhere on computer in some way). Local gulp package you can run npm install in the directory with package.json defined well already. Compser is only a bit more troublesme since it is still beta–but it is very cool for PHP developers.
php -r "readfile('https://getcomposer.org/installer');" > composer-setup.php
php -r "if (hash('SHA384', file_get_contents('composer-setup.php')) === '41e71d86b40f28e771d4bb662b997f79625196afcca95a5abf44391188c695c6c1456e16154c75a211d238cc3bc5cb47') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"
The commond above will download composer.phar into your current directory and since mostly we want to use composer as a convenient command on CentOS, let’s sudo mv composer.phar \usr\local\bin\composer and now you should be able be able enjoy composer as a command.
Now, navigate to the destination folder and run composer create-project flarum/flarum . --stability=beta and the project is there. You can begin to configure your MySQL, Nginx and php-cli or fpm to run the project!
