joomla3.6.5 nginx下 前台页面404错误

正常安装 joomla3.6.5后 后台可以打开 前台页面404 百度后发现是没有配置 nginx的伪静态规则  joomla官方提供了配置文件 地址：http://docs.joomla.org/Nginx  配置如下：

server {        listen 80;        server_name YOUR_DOMAIN;        server_name_in_redirect off;        access_log /var/log/nginx/localhost.access_log;        error_log /var/log/nginx/localhost.error_log info;        root PATH_ON_SERVER;        index index.php index.html index.htm default.html default.htm;        # Support Clean (aka Search Engine Friendly) URLs        location / {                try_files $uri $uri/ /index.php?$args;        }        # deny running scripts inside writable directories        location ~* /(images|cache|media|logs|tmp)/.*\.(php|pl|py|jsp|asp|sh|cgi)$ {                return 403;                error_page 403 /403_error.html;        }        location ~ \.php$ {            fastcgi_pass  127.0.0.1:9000;            fastcgi_index index.php;            include fastcgi_params;            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;            include /etc/nginx/fastcgi.conf;        }        # caching of files         location ~* \.(ico|pdf|flv)$ {                expires 1y;        }        location ~* \.(js|css|png|jpg|jpeg|gif|swf|xml|txt)$ {                expires 14d;        }}

伪静态规则在于 try_files $uri $uri/ /index.php?$args;  这句话 加入后重启nginx 前台页面正常了  我的nginx配置如下：

server {    listen       80;    server_name  xxxxx.xxxx.org;    charset utf-8;    access_log  /www/log/xxxxx.xxxx.org.log  main;    location / {        root /www/xxxxx.xxxx.org;        index index.php index.html index.htm;        try_files $uri $uri/ /index.php?$args;    }    error_page 500 502 503 504  /50x.html;    location = /50x.html {        root /usr/share/nginx/html;    }        location ~ \.php$ {        fastcgi_pass   127.0.0.1:9000;        fastcgi_index  index.php;        fastcgi_param  SCRIPT_FILENAME /www/xxxxx.xxxx.org$fastcgi_script_name;        include        fastcgi_params;    }     location ~ \.(less|sql)$ {        deny all;    }}
