The page you are are looking for is temporarily unavailable. Please try again later.

Today's website suddenly appears as follows:

The page you are are looking for is temporarily unavailable. Please try again later.

Very strange, I am not very familiar with the server side of the technology, so I queried the next Google, in the Https://wiki.archlinux.org/index.php/Nginx

The solution above:

Error:the page you are are looking for is temporarily unavailable. Please try again later.

This is because the FastCGI server has not been started.

How to solve it.

At first I doubted if Nginx hung up, and I started by PS aux | grep nginx, the result appears:

Visible Nginx is normal, originally intended to restart the Nginx:

/usr/local/nginx/sbin/nginx-t-c/usr/local/nginx/conf/nginx.conf,

Suddenly feel that there is no other way, there are colleagues prompted first in a directory run under test.html and test.php, resulting in HTML can run, PHP will not run.

Confirmed that PHP did not start, I have just also detected the process of PHP, there is no PHP process, this server I am not familiar with, colleagues to help view the next

CD/ETC/INIT.D, is the Web administrator often look at the place, with the system automatically start the service, programs and so on. Can look at:

Http://blog.wgzhao.com/2008/12/27/talk-about-rc-local.html's "Talk." /etc/rc.d/rc.local "

Found it:

/USR/LOCAL/PHP/SBIN/PHP-FPM start, what is php-fpm first?

is fastcgi Process Manager, an optional PHP fastgci execution mode, with a very specific application, especially in a busy Web site:

(1) Adaptable for regeneration (new!)

(2) Basic statistical functions (Apache ' s mod_status)

(3) Advanced process management function, able to gracefully stop/start

(4) Able to use different working users and different php.ini

(5) input, output log record ...

After the opening, everything returned to normal. Its server-side technology is still not enough to use in many places. Need to learn more use.
