1. 安装nginx

   yum install nginx

2. 设置nginx开启起动

   systemctl start nginx

3. 测试
   访问http://你的域名或IP/

   
   image

4. 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

5. 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

6. 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

9. 设置php-fpm开机启动

   systemctl enable php-fpm

10. 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;
}
}

11. 重起nginx

# systemctl restart nginx

12. 测试php
    创建/usr/share/nginx/html/index.php

# /usr/share/nginx/html/info.php

输入以下内容：
<?php phpinfo(); ?>

访问http://你的IP/index.php，正常情况下会出现 image
