#php源码安装
下载地址: https://www.php.net/distributions/php-8.2.8.tar.bz2open in new window
配置阶段:./configure
实行./configure时涌现缺点提示,大部分是由于缺省干系软件导致,看提示安装即可.
当涌现Thank you for using PHP.即配置完成.
编译阶段:make
在1cpu,1G内存,1G交流空间的情形下,make命令会最高占用99%的cpu资源,内存最高利用600M旁边.
如果说自有的ecs配置不高的情形下,选择源码编译并不是一个好的选择.
当涌现Build complete.即编译完成.
安装阶段:make install
查看一看默认安装了哪些模块,php -m
个中创造了libxml和sqlite3这便是为什么在配置阶段会提示安装libxml2-devel,sqlite-devel的缘故原由了.

#配置nginx做事器
在nginx里配置fastcgi协议的干系参数,将数据通过9000端口传递出去.
vim /usr/local/nginx/conf/nginx.conf
location ~ \.php$ { root /usr/local/nginx/html; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params;}

echo "<?php phpinfo(); ?>" >> /usr/local/nginx/html/index.php
#配置php解析器
监听9000端口进行程序解析.
php-cgi
实行命令:
/usr/local/bin/php-cgi -b 127.0.0.1:9000 -c /usr/local/php/php.ini
php-fpm
实行命令:php-fpm
vim /usr/local/etc/php-fpm.d/www.conf
listen = 127.0.0.1:9000
