XCache speed up for PHP

XCache is a fast and stable PHP opcode cache. Good testing and stable operation on large-flow/high-load production machines. After testing (on Linux) and supporting the latest release versions of all current PHP branches, such as Php_5_1 php_5_2 Php_5_3 Php_5_4. and perfectly supports thread-safe/windows. Better than a similar opcode cache, such as the ability to quickly follow up on PHP versions.

Installation steps:

1, decompression tar.gz bag

[[email protected] ~]# tar xf xcache-3.0.4.tar.gz  -c /usr/local/src[[ email protected] ~]# cd /usr/local/src[[email protected] src]# cd  xcache-3.0.4/###  viewing the installation steps [[Email protected] xcache-3.0.4]# vim installinstalltion:     $ phpize --clean && phpize    $ . /configure --help    $ cflags= ' Your cflags '  ./configure -- enable-xcache --enable...    $ make    $ su     # make install         (Update php.ini,  restart php)          ###  Use the local interpreter to probe the version number/extension API on which the module depends , generate the serial number token, and then generate the Configure file before compiling [[email protected] xcache-3.0.4]# /usr/local/php/bin/phpize  [[email protected] xcache-3.0.4]# ./configure --enable-xcache --enable-xcache-coverager -- enable-xcache-optimizer --with-php-config=/usr/local/php/bin/php-config#  Note:--enable-xcache             #  Enable Xcache--enable-xcache-vocerager   #  additional features--enable-xcache-optimizer  #  enable opcode optimization [[email protected]  xcache-3.0.4]# make && make install##  the path to the xcache.so module is prompted after the installation is complete,  We moved the xcache.so to the/usr/local/php/include/php/ext directory for easy Management installing shared extensions:     /usr/local/php/lib/php/extensions/no-debug-zts-20100525/[[email protected] xcache-3.0.4]#  mv /usr/local/php/lib/php/extensions/no-debug-zts-20100525/xcache.so  /usr/local/php/ include/php/ext/##  generate XCache Administrator's password (MD5 ciphertext) [[email protected] ~]# echo -n  ' 123456 '  | md5sume10adc3949ba59abbe56e057f20f883e

2, Consolidated PHP and XCache

3. Generate XCache Cache file

[Email protected] ~]# touch/tmp/xcache[[email protected] ~]# chmod 777/tmp/xcache

4. Manage with admin

In fact, to be a site, there are 5 ways to access:

(Physical directory, virtual directory, IP based, port based, host based)

#  Copy the XCache hypervisor to the Web site root [[email protected] xcache-3.0.4]# cp -a htdocs /usr/ local/apache/htdocs/xadmin#  Restart  httpd,  Restart the PHP-FPM service if the fastcgi mode is required [[email protected] ~] # service httpd restart[[email protected] ~]# service php-fpm  Restart Error: starting php-fpm: [21-jul-2014 18:55:21] notice: php message: php  Warning:  PHP Startup: Unable to load dynamic library  ' usr /local/php/include/php/ext/xcache.so '  - /usr/local/php/include/php/ext/xcache.so: undefined  symbol: core_globals_id in unknown on line 0#########################   ????????? #  Here I don't know what happens,  don't know if it's a version of the problem # httpd-2.2.27 , php-5.4.30 , xcache-3.0.4  , fastCGI  # #  I hope you will answer ##########################  later, I still use module way,  It's all OK. [[EMAIL&NBsp;protected] ~]# vi /etc/httpd/httpd.confloadmodule php5_module         modules/libphp5.so#LoadModule fastcgi_module         modules/mod_fastcgi.so[[email protected] httpd]# service httpd restart

Then access Http://localhost/xadmin, the user name is XCache, password is 123456;

In addition, Phpinfo can also be used to verify whether PHP supports XCache
