PHP (full name: PHP: Hypertext Preprocessor, i.e. "PHP: Hypertext Preprocessor") is an open source general-purpose computer scripting language, especially suitable for Developed for the web and can be embedded in HTML. The syntax of PHP draws on the characteristics of popular computer languages such as C language, Java and Perl, making it easy for ordinary programmers to learn.

Download the installation file
To be safe, use php official website download: https: //www.php.net/downloads
The download speed using the official website is slower, but the security is guaranteed. If you have no requirements for security, you can also search for related mirrors on Baidu. This article chooses the latest stable version PHP 8.1.6
wget https://www.php.net/distributions/php-8.1.6.tar.gz tar -zxvf php-8.1.6.tar.gz cd php-8.1.6
yum install libxml2 libxml2-devel libsqlite3x-devel openssl bzip2 libcurl-devel libcurl libjpeg libpng freetype gmp libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel zlib zlib-devel glibc glib2 ncurses curl gdbm-devel db4-devel libXpm-devel libX11-devel gd-devel gmp-devel expat-devel xmlrpc-c xmlrpc-c-devel libicu-devel libmcrypt-devel libmemcached-devel -y
Note: The current Centos official image has stopped serving,
yum install
Installationdevel
software, if an error is reported and cannot be installed, try overwriting the file contents inCentOS-Base.repo.rpmsave
in the/etc/yum.repos.d/
directory. ToCentOS-Linux-BaseOS.repo
,CentOS-AppStream.repo.rpmsave
is overwritten toCentOS-Linux-AppStream.repo
, please make a backup before operation
Because there is no oniguruma package in the yum source, here we use the github source code to compile and install. Project address: https://github.com/kkos/oniguruma
wget https://github.com/kkos/oniguruma/releases/download/v6.9.8/onig-6.9.8.tar.gz tar -zxvf onig-6.9.8.tar.gz cd onig-6.9.8 ./configure --prefix=/usr make && make install
For security reasons, we need to create a user for running php. Generally, this user is prohibited from logging in. This article creates a user The name and user group are both www
, this name can be customized
# 创建用户组 groupadd www # 创建用户 useradd -g www www -M -s /sbin/nologin
Specify user group
Do not create a home directory (a home directory is not required to run the program)
Do not allow login , more secure

apache , you need to add
--with-apxs2=/www/server/apache/bin/apxs in the compilation parameters, and the
--enable-fpm parameter can be removed, where
/www/server/apache is the installation directory of
apache. After compilation, uncomment the
php_module in the configuration file of
apache. , this article will not go into details about
apache configuration.
