APC cache is a PHP caching solution which stands for Alternative PHP Cache.<\/strong> It serves PHP pages from a cache thus helping to reduce server load. APC is an open source software and is updated from time to time.<\/p>\n

The following are the steps to install APC cache on a cPanel \/ Plesk OR even on a plan CentOS server:<\/p>\n

1)<\/strong> SSH to your server and go to a temporary directory<\/p>\n

\n
# cd \/usr\/local\/src<\/span><\/pre>\n<\/blockquote>\n
2)<\/strong> Download the latest APC version<\/p>\n
\n
# wget http:\/\/pecl.php.net\/get\/APC-3.1.6.tgz<\/span><\/pre>\n<\/blockquote>\n
3)<\/strong> Unpack the version and change to the APC directory<\/p>\n
\n
# tar -zxf APC-3.1.6.tgz <\/span><\/pre>\n
# cd APC-*<\/span><\/pre>\n<\/blockquote>\n
4)<\/strong> Create configuration files<\/p>\n
\n
# phpize<\/span><\/pre>\n<\/blockquote>\n
5)<\/strong> Search for the “php-config” file since you need to configure APC with it<\/p>\n
\n
# which php-config<\/span><\/pre>\n<\/blockquote>\n
6)<\/strong> Now, configure APC<\/p>\n
\n
# .\/configure --enable-apc --enable-apc-mmap --with-apxs\\\r\n --with-php-config=\/usr\/local\/bin\/php-config<\/pre>\n<\/blockquote>\n
7)<\/strong> Create the installation files and install APC<\/p>\n
\n
# make <\/span><\/pre>\n
# make install<\/span><\/pre>\n<\/blockquote>\n
Now that the APC cache is installed on your server, the final step is to activate the APC extension in the php.ini file.<\/p>\n
Locate the working php.ini file of your server<\/p>\n
\n
# php -i | grep php.ini<\/span><\/pre>\n<\/blockquote>\n
edit the file and search for “extension_dir”<\/strong> and place the following code below it (tweak the values as per your requirement):<\/p>\n
\n
extension=\"apc.so\" <\/span><\/pre>\n
apc.enabled=1 <\/span><\/pre>\n
apc.shm_segments=1 <\/span><\/pre>\n
apc.shm_size=256 <\/span><\/pre>\n
apc.ttl=3600 <\/span><\/pre>\n
apc.user_ttl=7200 <\/span><\/pre>\n
apc.num_files_hint=1024 <\/span><\/pre>\n
apc.mmap_file_mask=\/tmp\/apc.XXX <\/span><\/pre>\n
apc.enable_cli=1<\/span><\/pre>\n<\/blockquote>\n
Restart the Apache web server\u00a0 for changes to take affect. To confirm if APC is activated, execute<\/p>\n
\n
# php -i | grep apc<\/span><\/pre>\n<\/blockquote>\n
Note:<\/strong> once APC is installed, make sure the ‘apc.so’ file is created under the directory specified at the “extension_dir” in php.ini. If not, look for the exact path of the file and create a symlink under it.<\/p>\n","protected":false},"excerpt":{"rendered":"
