Nginx報錯：Sorry, the page you are looking for is currently unavailable. Please try again later.

查看了進程, nginx, php-fpm都在運行, 排除程序錯誤, 那么就是配置的問題了.

一個可能的錯誤, 是由於配置中的 fastcgi_pass 配置錯了

錯誤的配置如下 

server {
    listen       80; 
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;

    location ~ \.php$ {
        root /usr/share/nginx/html;
        fastcgi_pass 127.0.0.1:80;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
        index index.php;
    }   

    location / { 
        root /usr/share/nginx/html;
        index index.html;
    }   

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #   
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }   

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #   
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}  

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #   
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}  

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one 
    #   
    #location ~ /\.ht {
    #    deny  all;
    #}  
}

標紅的地方, 我以為是端口, 但是不是, 具體應該是 php-fpm 處理php腳本的端口吧, 改成 

fastcgi_pass 127.0.0.1:9000; 就好了 

還有一個問題, 訪問PHP可以訪問了, 但是訪問html不能訪問, 是因為 藍色標識的未添加, 就是下面這段 

location / { 
        root /usr/share/nginx/html;
        index index.html;
    }

第一次搞nginx, 遇到很多問題, 記錄之
