1. 安裝nginx

   yum install nginx

2. 設定nginx開啟起動

   systemctl start nginx

3. 測試
   訪問http://你的域名或IP/
   

4. 檢視nginx安裝位置

   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. 安裝php

   [不用這種]yum install php php-mysql php-fpm

   安裝過程中經常會見到如下問題：
   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)
   解決方法：
   把php-mysql換成php-mysqlnd
   即執行  

   yum install php php-mysqlnd php-fpm php-gd php-mbstring

6. php-mbstring如果不安裝，mb_substr字串擷取等無法用；

7. 配置php處理器

   vim /etc/php.ini

   查詢cgi.fix_pathinfo
   將 ;cgi.fix_pathinfo=1改為cgi.fix_pathinfo=0

8. 配置www.conf

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

   將
   user = nobody
   group = nobody
   改為
   user = nginx
   group = nginx
   前提是已經建立了nginx使用者和nginx組。

9. 起動php-fpm

   systemctl start php-fpm

10. 設定php-fpm開機啟動

    systemctl enable php-fpm

11. 配置nginx
    開啟/etc/nginx/conf.d/default.conf，如果不存在則建立
    貼上
    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;
    }
    }

12. 重起nginx

    systemctl restart nginx

13. 測試php
    建立/usr/share/nginx/html/index.php

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

    輸入以下內容：
    

訪問http://你的IP/index.php，正常情況下會出現

安裝gd擴充套件庫

yum install php-gd

1、如果HTML中套用PHP無法解析，如下操作：

開啟/etc/php-fpm-d/www.conf，將分號去掉

;security.limit_extensions = .php .php3 .php4 .php5

改為：

security.limit_extensions = .php .php3 .php4 .php5

2、開啟短標籤

/etc/php.ini

查詢short_open_tag改為

short_open_tag = On

3、出現PHP message: PHP Warning:  date(): It is not safe to rely on the system's timezone settings. 

說明時區設定有問題

/etc/php.ini

查詢 date.timezone 改為

date.timezone = PRC

然後重啟php-fpm服務

service php-fpm restart
