After upgrading to MacOS High Sierra (or any upgrade process previously), first thing I need to check is the local webserver status: apache, php, redis, mysql. Brew install php redis. Thankfully, MacOS High Sierra is now shipped with PHP 7.1 installed, which met the new standard for my future web developments.
PHP-redis is a must-installed library since I love the MySQL + Redis tandem for handling data storage and requests. Of course, along with the newly upgraded OS, the Apache installation in fresh installed with standard “It works!” welcome page.
Now, into the installation steps.
1. Install php71-redis Library
Easier said, I simply shot brew install php71-redis into Terminal and then served with Error, suggesting that I need to install Xcode Command Line Tools.
xcode-select --install
2. Unlink Previous PHP 5.6 Libraries
I tried to install again the library, but another error came along. It said the installed formulae was conflicting: different php versions install the same binaries. It suggested me to unlink all php 5.6 libraries. Ok then..
brew unlink php56
3. Install php71-redis (Again)
Hopefully this attempt for installing php71-redis library was a successful one.
brew install php71-redis
4. Edit php.ini; Include php71-redis Extension
Edit /etc/php.ini, add the extension as follows. If the php.ini file not exist, copy the php.ini~previous. Don’t forget to include the igbinary extensions too, so you won’t get problem my previous php56-redis module not loaded here.
5. Restart Apache
Final steps
sudo apachectl restart
