Install Additional PHP modules

By default few PHP modules are installed with LAMP or LEMP but Nextcloud required more PHP modules, so install required additional PHP modules & other prerequisites too.

[PHP 7.0 supported system]
$ sudo apt-get -y install php-cli php-json php-curl php-imap php-gd php-mysql php-xml php-zip php-intl php-mcrypt php-imagick php-mbstring wget bzip2 

[older (PHP5) systems]
$ sudo apt-get -y install php5-cli php5-json php5-curl php5-imap php5-gd php5-mysql php5-xml php5-zip php5-intl php5-mcrypt php5-imagick php5-mbstring wget bizp2

Modify PHP setting as per Nextcloud recommendation. Initially find the loaded php.ini file by firing the below command. This will print the loaded php.ini configuration file location.

$ php -i | grep "Loaded Configuration File"
Loaded Configuration File => /path to/php.ini

Modify the php.ini settings, PHP 7 supported system based on Nextcloud recommendation. Make sure, you have to take a backup of php.ini file before modification for best practice.

$ sudo cp /etc/php/7.0/apache2/php.ini /etc/php/7.0/apache2/php.ini.bk
$ sudo sed -i "s/memory_limit = .*/memory_limit = 512M/" /etc/php/7.0/apache2/php.ini
$ sudo sed -i "s/;date.timezone.*/date.timezone = Asia/Kolkata/" /etc/php/7.0/apache2/php.ini
