当我没初始配在lnmp的时候,用浏览器打开查看php能否解析网页的时出现File not found 不用惊奇让我我们分析一下
使用php-fpm解析PHP，"No input file specified"，"File not found"是令nginx新手头疼的常见错误，原因是php-fpm进程找不到SCRIPT_FILENAME配置的要执行的.php文件，php-fpm返回给nginx的默认404错误提示。
一、错误的路径被发送到php-fpm进程
出现这类错误，十个有九个是后端fastcgi进程收到错误路径(SCRIPT_FILENAME)，而后端fastcgi收到错误路径的原因大都是配置错误。
常见的nginx.conf的配置如下：
user www www;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_log logs/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root /usr/local/nginx/html; #指定索引文件的目录
index index.html index.htm index.php;
}
#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 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$ { #开启php解析
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME script$fastcgi_script_name
改为：
fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name; #指定路径
include fastcgi_params;
}
# fastcgi_params;
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
然后在重启nginx，打开浏览器查看php是否能解析网页！
