Faster and faster, making PHP 7 run faster

Guide

PHP 7 is much faster than 5.x. even if only the version upgrade is simple, we still hope it will become faster and faster, and then we will have more fu if we make some minor adjustments, let's try it!

Prerequisites

Speaking of PHP 7, you cannot run LAMP or LEMP. please First prepare the installation of the underlying service.

In the past, we wanted PHP to accelerate the processing speed. it was usually used with one of APC, eAccelerator, and XCache. if you forget them, you can use OPcache for implementation from now on, it is a PHP support module developed by Huixin, one of the PHP 7 developers. This implementation focuses on the LEMP architecture. the KIT Library uses the Remi version. do not forget to modify the path and set the value according to your actual environment.

Start setting

Install the OPcache package.

sudo yum -y install php70-php-opcache

Edit the main configuration file.

sudo vi /etc/opt/remi/php70/php.ini

Add these parameters.

zend_extension=opcache.so opcache.enable=1 opcache.enable_cli=1opcache.file_cache=/ home/opcache opcache.huge_code_pages=1

Start Huge Pages, which is a large temporary paging mechanism. for details, refer to The Linux Kernel Archives-Huge Pages. it is enough to change The test result on my machine to 512.

sudo sysctl -w vm.nr_hugepages=512

Create a dedicated OPcache directory.

sudo mkdir /home/opcache sudo chown nginx:nginx /home/opcache

Restart the PHP-FPM and you will see that OPcache has started.

sudo systemctl restart php70-php-fpm

In addition, we can also install memcached, which, as its name implies, uses memory as the cache to accelerate system operation.

sudo yum -y install memcached

Edit the main program file.

sudo vi /etc/sysconfig/memcached

There are not many parameters. please modify them as needed.

PORT-PORT. do not forget to enable the firewall. MAXCONN-total number of connections. CACHESIZE-memory usage, in KB. PORT = "11211" USER = "memcached" MAXCONN = "1024" CACHESIZE = "1024" OPTIONS = ""

Start memcached and enable it to automatically start after it is started.

sudo systemctl restart memcached sudo systemctl enable memcached

Open fire protection wall

sudo firewall-cmd --permanent --zone=public --add-port=11211/tcp

Then install the memcached for PHP support module.

sudo yum -y install php70-php-pecl-memcached

Restart PHP-FPM.

sudo systemctl restart php70-php-fpm

Finally, let's take a look at the phpinfo (); function display result. The memcached section indicates that the operation is successful.

Test result

Here, we directly reference the information from netizens on the other side. in this article, OneAPM-uses PHP 7 to accelerate Web applications, he tested 12 types of Wordpress 4.1.1, Drupal 8, phpBB 3.1.3, MediaWiki 1.24.1, Opencart 2.0.2.0, ike1.2.0, Geeklog 2.1.0, Magento 1.9.1.1, Traq 3.5.2, Cachet, Moodle 2.9-dev, and ZenCart 1.5.4 the comparison result of the suite. Taking Wordpress 4.1.1 as an example, we can see that PHP 7 is different from 5.3 ~ The Read speed (Read) and Latency (Latency) of 5.6 are greatly improved.
