centos7安装并配置nginx+php，centos7nginx

centos7安装并配置nginx+php

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/
   

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

   [不用这种]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 php-gd php-mbstring

6. php-mbstring如果不安装，mb_substr字符串截取等无法用；

7. 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

8. 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。

9. 起动php-fpm

   systemctl start php-fpm

10. 设置php-fpm开机启动

    systemctl enable php-fpm

11. 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;
    }
    }

12. 重起nginx

    systemctl restart nginx

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

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

    输入以下内容：
    

访问http://你的IP/index.php，正常情况下会出现

安装gd扩展库

yum install php-gd

1、如果HTML中套用PHP无法解析，如下操作：

打开/etc/php-fpm-d/www.conf，将分号去掉

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

改为：

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

2、开启短标签

/etc/php.ini

查找short_open_tag改为

short_open_tag = On

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

说明时区设置有问题

/etc/php.ini

查找 date.timezone 改为

date.timezone = PRC

然后重启php-fpm服务

service php-fpm restart
