准备工作

　　创建空文件夹

> mkdir /opt/php //创建目录
> cd /opt/php //进入目录

　　安装php运行依赖库

> yum install openssl-devel gcc gcc-c++ wget make libxml2 libxml2-devel openssl openssl-devel curl-devel libjpeg-devel libpng-devel freetype-devel 
　　 bison autoconf sqlite-devel bzip2-devel libcurl-devel libicu-devel libxslt-devel libzip-devel libtidy-devel libtidy
> yum --enablerepo=PowerTools install oniguruma-devel

 

下载源码

> wget https://www.php.net/distributions/php-8.0.6.tar.gz //下载php8
> tar vxf php-8.0.6.tar.gz //解压php压缩
> mv php-8.0.6 php8 //改名

　　配置准备

> mkdir /opt/php/php //建立php安装目录
> mkdir /opt/php/etc //建立php配置目录

配置php

> ./configure --prefix=/opt/php/php/ --with-config-file-path=/opt/php/etc  --enable-fpm --enable-mysqlnd --enable-opcache --enable-pcntl --enable-mbstring --enable-soap --enable-zip --enable-calendar  --enable-bcmath 
　　--enable-exif --enable-ftp --enable-intl --with-mysqli  --with-pdo-mysql --with-openssl --with-curl --with-gd --with-gettext  --with-mhash --with-openssl --with-mcrypt --with-tidy --enable-wddx  --with-xmlrpc --with-zlib

编译&安装

> make 
> make install

判断是否安转成功

 

> cd /opt/php/php/bin //进入php的安装目录下的bin
> ./php --version //查看版本号

 

　　出现版本号，则安装成功

linux 安装php8-DESTLIVE

 

可能出现的问题

　　在配置过程中，出现的问题基本上都是某个依赖包没有安装好，这几篇文章能给你一些帮助。

　　php8在centos7安装

　　error: C++ preprocessor "/lib/cpp" fails sanity check错误解决方法
