1、下载php源码
[root@VM-4-2-centos ~]# wget https://www.php.net/distributions/php-7.4.26.tar.gz --2023-07-25 17:16:00-- https://www.php.net/distributions/php-7.4.26.tar.gz Resolving www.php.net (www.php.net)... 185.85.0.29, 2a02:cb40:200::1ad Connecting to www.php.net (www.php.net)|185.85.0.29|:443... connected. ERROR: cannot verify www.php.net's certificate, issued by ‘/C=US/O=Let's Encrypt/CN=R3’: Issued certificate has expired. To connect to www.php.net insecurely, use `--no-check-certificate'.
如果出现错误：
解决办法 wget --no-check-certificate....
[root@VM-4-2-centos ~]# wget --no-check-certificate https://www.php.net/distributions/php-7.4.26.tar.gz --2023-07-25 17:17:35-- https://www.php.net/distributions/php-7.4.26.tar.gz Resolving www.php.net (www.php.net)... 185.85.0.29, 2a02:cb40:200::1ad Connecting to www.php.net (www.php.net)|185.85.0.29|:443... connected.

2、解压php
# tar -zxvf php-7.4.26.tar.gz # cd php-7.4.26
3、安装依赖
[root@VM-4-2-centos ~]# yum install gcc libxml2-devel [root@VM-4-2-centos ~]# yum install gcc build-essential sqlite-devel
4、编译安装
[root@VM-4-2-centos php-7.4.26]# ./configure --prefix=/usr/local/php
执行成功，如下所示：
Generating files configure: patching main/php_config.h.in configure: creating ./config.status creating main/internal_functions.c creating main/internal_functions_cli.c config.status: creating main/build-defs.h config.status: creating scripts/phpize config.status: creating scripts/man1/phpize.1 config.status: creating scripts/php-config config.status: creating scripts/man1/php-config.1 config.status: creating sapi/cli/php.1 config.status: creating sapi/phpdbg/phpdbg.1 config.status: creating sapi/cgi/php-cgi.1 config.status: creating ext/phar/phar.1 config.status: creating ext/phar/phar.phar.1 config.status: creating main/php_config.h config.status: executing default commands +--------------------------------------------------------------------+ | License: | | This software is subject to the PHP License, available in this | | distribution in the file LICENSE.

[root@VM-4-2-centos php-7.4.26]#
5、执行安装
[root@VM-4-2-centos php-7.4.26]# make [root@VM-4-2-centos php-7.4.26]# make install
6、查看目录
[root@VM-4-2-centos php-7.4.26]# cd /usr/local/php/ [root@VM-4-2-centos php]# ll total 20 drwxr-xr-x 2 root root 4096 Jul 25 17:31 bin drwxr-xr-x 3 root root 4096 Jul 25 17:31 include drwxr-xr-x 3 root root 4096 Jul 25 17:31 lib drwxr-xr-x 3 root root 4096 Jul 25 17:31 php drwxr-xr-x 4 root root 4096 Jul 25 17:31 var
7、配置环境变量
# vi /etc/profile
文件末尾添加如下：
unset -f pathmunge PATH=$PATH:/usr/local/php/bin export PATH
source /etc/profile
8、测试php环境变量是否成功
[root@VM-4-2-centos php]# php -i phpinfo() PHP Version => 7.4.26 System => Linux VM-4-2-centos 3.10.0-1160.88.1.el7.x86_64 #1 SMP Tue Mar 7 15:41:52 UTC 2023 x86_64 Build Date => Jul 25 2023 17:27:49
或者：php --version
[root@VM-4-2-centos php]# php --version PHP 7.4.26 (cli) (built: Jul 25 2023 17:29:54) ( NTS ) Copyright (c) The PHP Group Zend Engine v3.4.0, Copyright (c) Zend Technologies
9、测试创建一个php文件：1.php
[root@VM-4-2-centos ~]# php 1.php hello,php[root@VM-4-2-centos ~]#
