Nginx安装与配置(包括解决403错误,站点配置,_STORAGE_WRITE_ERROR_,No input file)

1.yum 安装nginx

nginx -v   #安装前检查
yum install nginx -y  #yum安装nginx

2.启动nginx并设置开机自启动
 

systemctl start nginx.service  #启动nginx
 systemctl stop  nginx.service  #关闭nginx
 systemctl enable nginx.service #设置nginx开机自启
 systemctl status nginx.service #查看nginx运行状态

3.安装完成后即可输入ip进行访问,若出现403,检查是否关闭防火墙
 

systemctl stop firewalld  #关闭防火墙

4.修改nginx配置文件 使其支持php解析,并配置相关参数

#            location = /50x.html {
#        }
#    }
  include vhosts/*.conf;
}

5.启动php-fpm(有两种启动方式,1.手动切换到目录下启动,2.设置开机自启动)
  a.手动启动:切换到php-fpm目录 执行./php-fpm     </usr/sbin/php-fpm>
  b.开机自启:systemctl enable php-fpm.service 

6.关闭 selinux(selinux开启可能会导致访问时出现403)  
  a. 临时关闭  

setenforce 0

  b. 永久关闭

vi /etc/selinux/config(find / -name selinux)

  将SELINUX=enforcing改为SELINUX=disabled 
  设置后需要重启才能生效

7.配置虚拟站点
a.find / -name nginx.conf #找到nginx.conf目录路径 </etc/nginx/nginx.conf>
b.在nginx目录下新建文件夹vhosts
c.切换到vhosts目录,新建web1.conf,web1.conf配置如下

server {
    listen       80;
    server_name  web1.com;
    root        /home/www/web/;
    index  index.php index.html;


    location / {
        index  index.php index.html;
    }
    location ~ .*.(php|php5)?$ {
        fastcgi_pass  127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param   SCRIPT_FILENAME   $document_root$fastcgi_script_name;
        fastcgi_param APPLICATION_ENV development;
        include fastcgi_params;
    }
}

d.并在nginx.conf的server最后添加  include vhosts/*.conf;
e.配置解析,find / -name hosts </etc/hosts> 添加域名及ip,还需在本机hosts中也添加ip地址

8.如果nginx安装或运行过程中出现 403 错误  首先检查是否具有读写权限,如果出现其他错误,可使用cat命令查看错误日志进行问题排查 </var/log/nginx/error.log>

9.部署tp框架在Nginx中(或者出现 No input file)

使Nginx支持tp框架支持:common中加入以下配置

return array(
	'URL_MODEL' => '2', //URL模式 或者 'URL_MODEL' =>3(URL兼容模式)
	'URL_PATHINFO_FETCH' => ':get_path_info', //加入此项配置
);

Nginx.conf:
location / { // …..省略部分代码
   if (!-e $request_filename) {
   rewrite  ^(.*)$  /index.php?s=$1  last;
   break;
    }
 }

如出现下图情况(_STORAGE_WRITE_ERROR_),请检查Runtime目录是否具有读写权限

最后
