Centos7服务器安装php，并与web server的链接配置。
本文使用 阿里云服务器 Centos 7 Linux 服务器。
rpm 安装 PHP7 相应的 yum源
CentOS/RHEL 7.x:
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
CentOS/RHEL 6.x:
rpm -Uvh https://mirror.webtatic.com/yum/el6/latest.rpm
RPM是RedHat Package Manager（RedHat软件包管理工具）类似Windows里面的“添加/删除程序”
rpm 执行安装包 二进制包（Binary）以及源代码包（Source）两种。
二进制包可以直接安装在计算机中，而源代码包将会由RPM自动编译、安装。源代码包经常以src.rpm作为后缀名。
官方CentOS 7 rpm源中不包含PHP7源

Nginx的配置
1.Nginx配置一个service:
server{
listen 80;
server_name www.test.com;
root /var/www/test;
index index.php index.html index.htm;
location / {
if (!-e $request_filename) {
rewrite ^(.*)$ /index.php?s=/$1 last;
break;
}
}
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
其他配置请参考 Nginx 配置参数详情。
2.启动php-fpm和设置开机启动:
systemctl start php-fpm
systemctl enable php-fpm
梳理
