PHP¶
Create Backup¶
If you have PHP already installed and would like to take a backup of the configuration files, you can run the following commands:
Note
You can copy and paste the whole block below into your SSH terminal
mkdir /root/php_upgrade_backup-$(date +%d_%b_%Y)
php -v > /root/php_upgrade_backup-$(date +%d_%b_%Y)/version
php -m > /root/php_upgrade_backup-$(date +%d_%b_%Y)/modules
php -i > /root/php_upgrade_backup-$(date +%d_%b_%Y)/info
rpm -qa | grep -i php > /root/php_upgrade_backup-$(date +%d_%b_%Y)/rpms
cp -r /etc/php.d/ /root/php_upgrade_backup-$(date +%d_%b_%Y)/
cp -r /etc/php-fpm.conf /root/php_upgrade_backup-$(date +%d_%b_%Y)/
cp -r /etc/php-fpm.d/ /root/php_upgrade_backup-$(date +%d_%b_%Y)/
cp /etc/php.ini /root/php_upgrade_backup-$(date +%d_%b_%Y)/
Remi Repository¶
We use the Remi yum repository for PHP. You can install the Remi repository with the command:
CentOS 7¶
wget http://rpms.remirepo.net/enterprise/remi-release-7.rpm && rpm -Uvh remi-release-7.rpm && rm -f remi-release-7.rpm
Install / Downgrade¶
If you are installing or downgrading PHP you need to remove PHP from the server and then follow the install guide below. We can remove PHP with the command:
We highly recommend taking a backup before running this command (See PHP Backup above)
yum remove "php*"
Install PHP¶
This includes the PHP modules required by Shopware.
PHP 7.0¶
yum install --enablerepo=remi-php70,remi,epel php php-pdo php-mysqlnd php-opcache php-xml php-mcrypt php-gd php-devel php-mysql php-intl php-mbstring php-bcmath php-json php-pecl-zip php-iconv php-pecl-apcu php-pecl-redis php-fpm php-zip php-soap php-ioncube-loader composer

yum install --enablerepo=remi-php71,remi,epel php php-pdo php-mysqlnd php-opcache php-xml php-mcrypt php-gd php-devel php-mysql php-intl php-mbstring php-bcmath php-json php-pecl-zip php-iconv php-pecl-apcu php-pecl-redis php-fpm php-zip php-soap php-ioncube-loader composer
PHP 7.2¶
yum install --enablerepo=remi-php72,remi,epel php php-pdo php-mysqlnd php-opcache php-xml php-pecl-mcrypt php-gd php-devel php-intl php-mbstring php-bcmath php-json php-pecl-zip php-iconv php-pecl-apcu php-pecl-redis php-fpm php-zip php-soap php-ioncube-loader composer

Update PHP¶
You can perform an update of PHP with the following command depending on the desired version:
PHP 7.0¶
yum update --disablerepo='*' --enablerepo=base,remi-php70,remi,epel,updates 'php-*'
PHP 7.1¶
yum update --disablerepo='*' --enablerepo=base,remi-php71,remi,epel,updates 'php-*'
PHP 7.2¶
yum update --disablerepo='*' --enablerepo=base,remi-php72,remi,epel,updates 'php-*'
PHP 7.3¶
yum update --disablerepo='*' --enablerepo=base,remi-php72,remi,epel,updates 'php-*'
If any of the following packages are updated as dependencies, NGINX will require a restart after updating PHP
curl
nss
openssl
libcurl
You can restart NGINX with the commands:
nginx -t
systemctl restart nginx
OPcache Settings¶
Review and then apply the OPcache settings (Simply copy and paste the entire block below):
sed -i 's/opcache.memory_consumption=128/opcache.memory_consumption=512/g' /etc/php.d/*opcache.ini
sed -i 's/opcache.interned_strings_buffer=8/opcache.interned_strings_buffer=12/g' /etc/php.d/*opcache.ini
sed -i 's/opcache.max_accelerated_files=4000/opcache.max_accelerated_files=60000/g' /etc/php.d/*opcache.ini
sed -i 's/;opcache.save_comments=0/opcache.save_comments=1/g' /etc/php.d/*opcache.ini
sed -i 's/;opcache.fast_shutdown=0/opcache.fast_shutdown=1/g' /etc/php.d/*opcache.ini
sed -i 's/;opcache.load_comments=0/opcache.load_comments=1/g' /etc/php.d/*opcache.ini
sed -i 's/;opcache.revalidate_freq=2/opcache.revalidate_freq=5/g' /etc/php.d/*opcache.ini
sed -i 's/;opcache.enable_file_override=0/opcache.enable_file_override=1/g' /etc/php.d/*opcache.ini
You can find more information on OPcache here
APCu Settings¶
Review and then apply the APCu settings (Simply copy and paste the below):
sed -i 's/;apc.shm_size=32M/apc.shm_size=512M/g' /etc/php.d/*apcu.ini
You can find more information on APCu here
/etc/php.ini Settings¶
Review and copy the settings from /root/php_upgrade_backup-$(date +%d_%b_%Y)/php.ini to /etc/php.ini. Alternatively use our standard settings for the php.ini file (You can copy and paste the whole block below into your SSH terminal):
cp /etc/php.ini /root/php.ini.default
sed -ie "s_;date.timezone =_date.timezone = \"Europe/London\"_g" /etc/php.ini
sed -ie "s/memory_limit = 128M/memory_limit = 1024M/" /etc/php.ini
sed -ie "s/max_execution_time = 30/max_execution_time = 1800/" /etc/php.ini
sed -ie "s/max_input_time = 60/max_input_time = 90/" /etc/php.ini
sed -ie "s/short_open_tag = Off/short_open_tag = On/" /etc/php.ini
sed -ie "s/;always_populate_raw_post_data = On/always_populate_raw_post_data = -1/" /etc/php.ini
sed -ie "s/expose_php = On/expose_php = Off/" /etc/php.ini
sed -ie "s/upload_max_filesize = 2M/upload_max_filesize = 8M/" /etc/php.ini
PHP-FPM Default Pool¶
Stop the default PHP-FPM pool www from running with the command:
echo ";Default file, please don't remove" > /etc/php-fpm.d/www.conf
Start PHP-FPM¶
Configuration Test¶
Run a configuration test of PHP-FPM before starting:
php-fpm -t
[21-Aug-2019 07:53:29] NOTICE: configuration file /etc/php-fpm.conf test is successful
Start PHP-FPM¶
You can then start the PHP-FPM service with the command
systemctl start php-fpm
Start On Boot¶
You can also enable PHP-FPM to start on boot:
systemctl enable php-fpm
