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 (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

CentOS 6​

wget http://rpms.remirepo.net/enterprise/remi-release-6.rpm && rpm -Uvh remi-release-6.rpm && rm -f remi-release-6.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 Magento:

PHP 5.6​

yum install \
    --disablerepo='*' \
    --enablerepo=base,remi-php56,remi,epel,updates \
    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-iconv php-pecl-redis \
    php-fpm php-zip php-soap

PHP 7.0​

yum install \
    --disablerepo='*' \
    --enablerepo=base,remi-php70,remi,epel,updates \
    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-iconv php-pecl-redis \
    php-fpm php-zip php-soap

PHP 7.1​

yum install \
    --disablerepo='*' \
    --enablerepo=base,remi-php71,remi,epel,updates 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-iconv php-pecl-redis php-fpm php-zip php-soap

    --disablerepo='*' \
    --enablerepo=base,remi-php72,remi,epel,updates \
    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-iconv php-pecl-redis php-fpm \
    php-zip php-soap

Update PHP​

You can perform an update of PHP with the following command depending on the desired version:

PHP 5.6​

yum update --disablerepo='*' --enablerepo=base,remi-php56,remi,epel,updates 'php-*'

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-*'

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=1/opcache.save_comments=0/g' /etc/php.d/*opcache.ini
sed -i 's/;opcache.load_comments=1/opcache.load_comments=0/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

/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:

sed -ie "s_;date.timezone =_date.timezone = \"Europe/London\"_g" /etc/php.ini
sed -ie "s/; max_input_vars = 1000/max_input_vars = 20000/g" /etc/php.ini
sed -ie "s/memory_limit = 128M/memory_limit = 512M/" /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
