XCache Introduction The principles and functions of the PHP accelerator (see PHP-FPM Server for Lamp architecture) are described earlier, and XCache, as one of the most widely used PHP accelerators, performs better than earlier Eaccelerator accelerators, Therefore, this time the PHP program in the implementation of the accelerator XCache on its performance impact. Installing XCache Copy Code # installation Tar XF xcache-3.0.3.tar.gz CD xcache-3.0.3 /usr/local/php/bin/phpize # XCache is installed as an add-on module for PHP ./configure--enable-xcache--with-php-config=/usr/local/php/bin/php-config Make && make install # at the end of installation, a line similar to the following will appear: Installing Shared extensions:/usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/ # edit php.ini, integrate PHP and XCache: # First, import the sample configuration provided by XCache into the php.ini MKDIR/ETC/PHP.D # This is the configuration file scan directory that was configured before PHP was installed The CP XCACHE.INI/ETC/PHP.D # Xcache.ini file is in the XCache source directory. # Next Edit/etc/php.d/xcache.ini, find the line beginning with extension and modify it to the following line: Extension =/usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/xcache.so # If there are multiple extension lines in the php.ini file, make sure that this new row is ranked first. # See if XCache has been installed successfully: /usr/local/php/bin/php-m |grep-i XCache Copy Code Opcache Introduction A new generation of PHP accelerators, developed by Zend, is similar to XCache, in that it buffers PHP-executed data into memory to avoid duplication of compilation, allowing direct use of buffer-compiled code to increase speed and reduce server load, but with better performance than XCache , see test results Installing Opcache Copy Code wget http://pecl.php.net/get/zendopcache-7.0.2.tgz Tar xzf zendopcache-7.0.2.tgz CD zendopcache-7.0.2 /usr/local/php/bin/phpize ./configure--with-php-config=/usr/local/php/bin/php-config Make Make install # configuration file settings, can be directly at the end of the php.ini to add the following, but in the PHP configuration file scanning directory PHP.D configuration of new files Opcache.ini, easy to manage, Php-config-scan-dir is compiled when installing PHP defined # Vi/etc/php.d/opcache.ini [Opcache] Zend_extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/opcache.so OPCACHE.MEMORY_CONSUMPTION=128 # Allocated memory size, in megabytes (MB), that is, how much precompiled PHP code can be stored Opcache.interned_strings_buffer=8 # interned string for memory size, in megabytes opcache.max_accelerated_files=4000 # Maximum number of files allowed to cache OPCACHE.REVALIDATE_FREQ=60 # How long to check file timestamps to change shared memory allocations in S Opcache.fast_shutdown=1 # Whether to turn on the fast off queue function, 1 to turn on Opcache.enable_cli=1 # allows PHP programs to be cached under the CLI #检查模块安装成功:/usr/local/php/bin/php-m |grep-i Opcache Copy Code HHVM Introduction HipHop VM (HHVM) is a virtual machine launched by Facebook to execute PHP code, which is a PHP JIT (just-in-time) compiler with the advantage of generating fast code and instant compilation; HHVM PHP code compiled into C + + programs to execute, execution efficiency has been significantly improved; According to Facebook, HHVM has made significant improvements in speed, 60% faster than the PHP interpreter currently in use, while using 90% less memory Installing HHVM Because at present HHVM also imposes the development stage, the domestic uses in the production environment is very few, Installation of the required environment is more complex (such as CentOS6.5 under the Boost-system and Boost-filesystem version is too low), I am still in the commissioning test phase, and so forth the test results, and then the HHVM test results are posted. Test steps # Find another virtual machine and stress test the httpd server (192.168.1.110) # test Tool using Apache's own benchmark tool AB # The test method is as follows: Ab-c 20-n http://192.168.1.110:8080/index.php # Note: The test takes 20 concurrency and, without affecting access, looks at the acceleration effect of the XCache accelerator; The test page uses the login page of the previous phpmyadmin that you just deployed index.php # Note: In order to better test the PHP accelerator cache features, you can test a few times in a row, get a stable value |
