解决Nginx服务器配置多站点时filenotfound的错误

配置nginx + php5-fpm
最初的nginx的配置文件
server {
listen 80; ## listen for ipv4; this line is default and implied
#listen [::]:80 default_server ipv6Only=on; ## listen for ipv6
# Make site accessible from http://localhost/
server_name localhost;
location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico|xml)$ {
access_log off;
expires 30d;
root /var/www;
}
location / {
root /var/www;
index index.php;
# First attempt to serve request as file, then
# as directory, then fall back to index.html
try_files $uri $uri/ /index.php;
}
#location /doc/ {
# alias /usr/share/doc/;
# autoindex on;
# allow 127.0.0.1;
# deny all;
#}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
#error_page 500 502 503 504 /50x.html;
#location = /50x.html {
# root /usr/share/nginx/www;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php.*$ {
fastcgi_pass backend;
fastcgi_index index.php;
set $real_script_name $fastcgi_script_name;
set $path_info "";
if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)") {
set $real_script_name $1;
set $path_info $2;
}
fastcgi_param PATH_INFO $path_info;
fastcgi_param SCRIPT_FILENAME $document_root$real_script_name;
fastcgi_param SCRIPT_NAME $real_script_name;
include /etc/nginx/fastcgi_params;
#fastcgi_param QUERY_STRING $query_string;
#fastcgi_param REQUEST_METHOD $request_method;
#fastcgi_param CONTENT_TYPE $content_type;
#fastcgi_param CONTENT_LENGTH $content_length;
#fastcgi_intercept_errors on;
#fastcgi_ignore_client_abort off;
#fastcgi_connect_timeout 36000;
#fastcgi_send_timeout 36000;
#fastcgi_read_timeout 36000;
#fastcgi_buffer_size 128k;
#fastcgi_buffers 4 256k;
#fastcgi_busy_buffers_size 256k;
#fastcgi_temp_file_write_size 256k;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
location ~ /\.ht {
deny all;
}
}
upstream backend {
server 127.0.0.1:9000;
}

上面的配置文件配置下来，请求index.php文件产生file not found的错误，最终确定确定导致这个错误的原因是，在下面的配置部分要加上红色部分，问题解决
location ~ \.php.*$ {
root /var/www;
fastcgi_pass backend;
fastcgi_index index.php;
set $real_script_name $fastcgi_script_name;
set $path_info "";
if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)") {
set $real_script_name $1;
set $path_info $2;
}
fastcgi_param PATH_INFO $path_info;
fastcgi_param SCRIPT_FILENAME $document_root$real_script_name;
fastcgi_param SCRIPT_NAME $real_script_name;
include /etc/nginx/fastcgi_params;
#fastcgi_param QUERY_STRING $query_string;
#fastcgi_param REQUEST_METHOD $request_method;
#fastcgi_param CONTENT_TYPE $content_type;
#fastcgi_param CONTENT_LENGTH $content_length;
#fastcgi_intercept_errors on;
#fastcgi_ignore_client_abort off;
#fastcgi_connect_timeout 36000;
#fastcgi_send_timeout 36000;
#fastcgi_read_timeout 36000;
#fastcgi_buffer_size 128k;
#fastcgi_buffers 4 256k;
#fastcgi_busy_buffers_size 256k;
#fastcgi_temp_file_write_size 256k;
}
