Free implementation method of website acceleration PHP buffer_PHP tutorial

We know that Zend has a free optimization engine for PHP, but FreeLAMP this time uses a buffering product called PHP Accelerator. We have explained several methods of acceleration in the article "LAMP Acceleration", among which we mentioned PHP Accelerator. Its installation method is very simple, but you need to go to its website to obtain an activation key. 1. Download: www.php-accelerator.co.uk/download.php 2. Obtain the activation key and install: www.php-accelerator.co.uk/activate.php After registering your SERVER_NAME, you will get the following prompt ： Your key for www.freelamp.com is 8edfd13946c96309244fcca309415902 Now you must set the key for www.freelamp.com in your site configuration. For single domains not using virtual hosts The key can be set in the php.ini file as follows: # PHPA key for www.freelamp.com 　# 　phpa.registration_key = 8edfd13946c96309244fcca309415902 　　For domains setup as a virtual host 　　Add the key to the domain specific section for your web server. .com 　# ... (other vhost specific config) 　　# php settings 　　php_value phpa.registration_key 8edfd13946c96309244fcca309415902 　　# also enable phpa if set to off in the php.ini (the default is on) 　　php_value phpa 1 　　 　　Specific phpa value of For settings, please refer to the configuration of the CONFIGURATION file that comes with the software. Since most websites are configured with virtual hosts, it is recommended to use php_value phpa. For example: php_value phpa.tweaks off php_value phpa.cache_dir /tmp php_value phpa.file_perms 400 php_value phpa.ignore_files "/index.php, /a/test.php" # php_value phpa.ignore_dirs "/data/WWW/site1/,/ cache/" php_value phpa.shm_size 8 php_value phpa.shm_key 0xc0deb00 php_value phpa.shm_perms 664 3. Set php.ini Suppose we unzip the downloaded file to /usr/local/php, then add: zend_extension to php.ini =/usr/local/php/php_accelerator_1.2p2.so and comment out the original Zend optimization engine: # zend_extension=/usr/local/Zend/lib/ZendOptimizer.so Restart Apache and use a browser to browse any PHP page See that some files starting with phpa are generated under /tmp. Another way to check whether buffering is working is to look at the output of phpinfo(). The original description of the Zend optimization engine has been shown as: This program makes use of the Zend Scripting Language Engine: Zend Engine v1.1.1, Copyright ( c) 1998-2001 Zend Technologies 　With the PHP Accelerator v1.2p2, Copyright (c) 2001-2002, by Nick Lindridge 　What needs to be explained is that the method on the INSTALL installation instructions, the .so file and the real .so file There are differences, so you need to pay attention to this difference when installing. 4. Adjust the buffer size. PHP Accelerator provides buffer management commands: phpa_cache_admin -mv observes the buffering situation of the memory. phpa_cache_admin -fv observes the buffering situation of the file. phpa_cache_admin -k sets the buffer size. 5. Summary. The INSTALL file provided by the software explains the performance issues. I will not elaborate on some of these statements here. It should be noted that FreeLAMP.com’s articles are currently not PHP-based, but the forum system is PHP-based, so the performance improvement will only be an improvement in the forum system.
