yum install nginx

设置nginx开启起动

systemctl start nginx

测试
访问http://你的域名或IP/
查看nginx安装位置

whereis nginx

nginx: /usr/sbin/nginx /etc/nginx /usr/share/nginx /usr/share/man/man3/nginx.3pm.gz /usr/share/man/man8/nginx.8.gz

安装php

yum install php php-mysql php-fpm

安装过程中经常会见到如下问题：
2:postfix-2.10.1-6.el7.x86_64 有缺少的需求 libmysqlclient.so.18()(64bit)
2:postfix-2.10.1-6.el7.x86_64 有缺少的需求 libmysqlclient.so.18(libmysqlclient_18)(64bit)
解决方法：
把php-mysql换成php-mysqlnd
即执行

yum install php php-mysqlnd php-fpm

配置php处理器

vim /etc/php.ini

查找cgi.fix_pathinfo
将 ;cgi.fix_pathinfo=1改为cgi.fix_pathinfo=0
7. 配置www.conf

vim /etc/php-fpm.d/www.conf

将
user = nobody
group = nobody
改为
user = nginx
group = nginx
前提是已经创建了nginx用户和nginx组。
8. 起动php-fpm

systemctl start php-fpm

设置php-fpm开机启动

systemctl enable php-fpm

配置nginx
打开/etc/nginx/conf.d/default.conf，如果不存在则创建
粘贴
server {
listen 80;
server_name server_domain_name_or_IP;

note that these lines are originally from the "location /" block

root /usr/share/nginx/html;
index index.php index.html index.htm;

location / {
try_files $uri $uri/ =404;
}
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}

location ~ .php$ {
try_files $uri =404;
root /usr/share/nginx/html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi.conf;
}
}
重起nginx

centos7安装并配置nginx+php
