Various PHP installation and expansion methods

Various PHP installation and expansion methods PHP has various installation and expansion methods, including package-managed yum installation, pecl installation, and underlying source code compilation and installation.

Package-managed installation and uninstallation are particularly convenient, while source code-compiled installation facilitates parameter optimization.

We recommend package-managed installation to build a local development environment to save time. For the online deployment environment, it is recommended to compile and install the environment to facilitate optimization.

Install yum

# Yum installation can automatically install extended. so dynamic library, and configure php. ini # such as installing mysql expand yum search mysql | grep php # We search to expand the name of the php-mysql.x86_64sudo yum install php-mysql # so php-mysql expansion will be installed # if the emergence of extended version and php version conflict, you can install any of the following yum sources: atomic-release.noarchwebtatic-release.noarch # these sources provide php extensions for other versions, and each source provides multiple versions for specific extensions, you just need to install one source. For example: atomic source can search for mysql 5.4 expansion atomic-php54-php-mysql.x86_64 webtatic source can search for mysql 5.5 expansion php55w-mysql.x86_64

Source code compilation and installation

# Brief introduction: add it next time # Download the extended source code, go to the source code directory, and run the phpize command to generate the configure detection script for the compilation configuration file, # execute the configure script and generate the compilation configuration file makefile with parameters # make & make install the dynamic library that vividly expands # migrate the generated extended dynamic library. so file to php. # php. ini adds configuration information for this extension in the section.

Check whether mysql expansion is successfully installed

php -i | grep mysql

After successful installation, the above command displays the mysql expansion status information in a section.

However, you need to restart to expand the load to the running environment.Web servicesOrPhp-fpm
