nginx

一、安装LNMP之前要安装EPEL，以便安装源以外的软件，如Nginx，phpMyAdmin等。

yum install epel-release

二、安装Nginx

a) yum install nginx 
b) systemctl start nginx #启动nginx         systemctl stop nginx 
c) systemctl enable nginx #设置开机启动

三、修改nginx的配置

 1 vim /etc/nginx/conf.d/default.conf  
 2 server {   
 3     listen       80;   
 4     server_name  server_domain_name_or_IP;   
 5    
 6     location / {   
 7         root   /usr/share/nginx/html;   
 8         index  index.php index.html index.htm;   
 9     }   
10    
11     error_page  404              /404.html;   
12    
13     # redirect server error pages to the static page /50x.html   
14     error_page   500 502 503 504  /50x.html;   
15     location = /50x.html {   
16         root   /usr/share/nginx/html;   
17     }   
18    # 更改nginx配置文件识别php 
19     location ~ .php$ {   
20         root           /usr/share/nginx/html;   
21         try_files $uri =404;   
22         fastcgi_pass   127.0.0.1:9000;   
23         fastcgi_index  index.php;   
24         fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;   
25         include        fastcgi_params;   
26     }   
27        
28 }

四、设置图片，以及访问错误的时候跳转

      location ~* .(js|css|jpg|jpeg|gif|swf)$ { 
                if (!-f $request_filename){ 
                        rewrite ^/(.*)$ /index.html last; 
                } 
        }

    location ~ .*.(gif|jpg|jpeg|png)$ {
        expires 24h;
            root /opt/;#指定图片存放路径    
            proxy_store on;    
            proxy_store_access user:rw group:rw all:rw;
            proxy_temp_path         /opt/;#图片访问路径    
            proxy_redirect          off;
            proxy_set_header        Host 127.0.0.1;
            client_max_body_size    10m;
            client_body_buffer_size 1280k;
            proxy_connect_timeout   900;
            proxy_send_timeout      900;
            proxy_read_timeout      900;
            proxy_buffer_size       40k;
            proxy_buffers           40 320k;
            proxy_busy_buffers_size 640k;
            proxy_temp_file_write_size 640k;
            if ( !-e $request_filename)
            {
                 proxy_pass  http://127.0.0.1;#默认80端口    
            }
    }
