Configuration and optimization of PHP in Kangle server environment

Configuration and optimization of PHP in the Kangle server environment

Kangle is a stable and efficient server software. Many websites choose to run in the Kangle environment. As a popular server-side scripting language, PHP is often used with Kangle. This article will introduce how to configure and optimize PHP in the Kangle server environment to improve the performance and security of the website.

1. PHP configuration

1. Find the php.ini file

In the Kangle server, the PHP configuration file is usually located at /3rd/php54/php. ini. You can modify PHP configuration options by editing this configuration file.

2. Adjust the memory limit

memory_limit = 256M

By modifying the memory_limit option, you can set the maximum amount of memory that a PHP script can use. Depending on your site's needs, adjust this value appropriately to avoid out-of-memory issues.

3. Turn on the error log

error_reporting = E_ALL
log_errors = On
error_log = /your/error/log/path

Turning on the error log can help you discover and solve problems in PHP operation in time.

4. Adjust the upload file limit

upload_max_filesize = 20M
post_max_size = 25M

According to the needs of the website, the size limit of the uploaded file can be appropriately adjusted.

2. PHP optimization

1. Turn on OPcache

extension = opcache.so
opcache.enable = 1
opcache.enable_cli = 1
opcache.memory_consumption = 128
opcache.interned_strings_buffer = 8
opcache.max_accelerated_files = 4000
opcache.revalidate_freq = 60

OPcache is an extension of PHP that can improve the execution speed of PHP code. By enabling OPcache in php.ini, you can cache PHP scripts and reduce parsing and compilation time.

2. Enable caching

$memcached = new Memcached();
$memcached->addServer('localhost', 11211);

Using caching can reduce the number of database queries and improve the response speed of the website. In PHP, you can use extensions such as Memcached to implement caching functions.

3. Avoid long-term execution of scripts

Long-term execution of PHP scripts will consume server resources and affect the performance of the website. You can limit the execution time of a script by setting the max_execution_time option to prevent the script from running indefinitely.

Conclusion
