?>Hit your browser http://[ip-address]/i.php and you should see PHP7 loaded.PHP 7.2.13Once you are done verify it’s correct, do remove the file:# rm /var/www/html/i.phpGitGit is one of the Version Control System, VCS exist and most of the software development these days MUST have VCS over their codes..Else, it would be nightmare, in case of losing the codes, or try to rollback, or even to track changes made to the codes.To install Git:# sudo yum install gitVerify the installation:# git –version git version 1.8.3.1ComposerThe last stack we need these days, is dependency manager — in our stack is the PHP dependency manager — Composer.Back in the old days, I use to go to websites, to download the PHP package, require the file, and use the package..Sometimes the package just break, did not work as expected due to not meet the version or requirement of the package.With Composer available, with single command, we will get the package we want, with correct dependency.To be honest, the first time I use Composer it’s like, whaddaaa…how?.why?.argh..so hard..but time flies..Now I manage to create my own PHP packages, even for Laravel frameworks — you may visit here..Cleanique Coders is a business I registered in 2016, for software development and training services related to software development, hence the Github account for it created..Most of packages created I do keep it there.So here the installation:# php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"# php -r "if (hash_file('sha384', 'composer-setup.php') === '93b54496392c062774670ac18b134c3b3a95e5a5e5c8f1a9f115f203b75bf9a129d5daa8ba6a13e2cc8a1da0806388a8') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"# php composer-setup.php# php -r "unlink('composer-setup.php');"# mv composer.phar /usr/local/bin/composerAll the above commands will download the composer-setup.php file and verify the installer and run the installer..Once installed, it will remove the installer and make composer.phar available globally.Verify the installation:# composer –versionComposer version 1.8.0 2018-12-03 10:31:16RedisThe last part of this story, is Redis.Previously, I did not know anything about Redis and it purposes..Until I get my hands on Laravel..Exploring Laravel and ended up using Redis.Redis is good for you cache, reduced the I/O, connection to database by using in-memory key-value — it won’t store in any files or database, just memory, RAM.Other than use for cache, it can be use for session management like in Laravel.To install Redis:# sudo yum install redisStart the Redis:# sudo systemctl start redisCheck Redis status:# sudo systemctl status redis● redis.service – Redis persistent key-value database Loaded: loaded (/usr/lib/systemd/system/redis.service;
