使用编译安装php的方法
首先安装php相关依赖

yum -y install libxml2-devel openssl-devel curl-devel libjpeg-devel libpng-devel libicu-devel freetype-devel openldap-devel openldap openldap-devel
yum -y install gcc gcc-c++ make  sqlite-devel.x86_64  oniguruma-devel.x86_64  libxslt-devel.x86_64  libzip-devel.x86_64 

下载php本体(官方链接) #以7.4.28版本为例

wget https://www.php.net/distributions/php-7.4.28.tar.gz

进入文件夹

cd php-7.4.28

运行脚本

./configure \
--prefix=/usr/local/php \
--with-config-file-path=/usr/local/php/etc \
--with-fpm-user=www \
--with-fpm-group=www \
--with-curl \
--with-MySQL=/usr/local/mysql \
--with-freetype-dir=/usr/local/freetype \
--enable-gd \

--enable-soap \
--enable-sockets \
--enable-sysvsem \
--enable-sysvshm \
--enable-xml \
--enable-zip \

编译并安装

make && make install

将配置文件做一个软连接到etc下

ln -s /usr/local/php/etc/php.ini /etc/php.ini
