This article mainly introduces how to start the Shell script PHP built-in FastCGI Server, has a certain reference value, interested friends can refer to the next, I hope you read this article after a lot of gains, the following let Xiaobian with everyone to understand.

A few days ago the working platform from Ubuntu 9.10 Karmic update to 10.04 Lucid, Lucid official source comes with PHP5.3.2, previously used dotdeb source can not be used, has been very fond of this source, not only provides PHP5.3 but also php5-fpm this very useful fcgi process manager, which is not available in the official source. Although it is possible to force dotdeb, there are bound to be many packages that have dependency problems, and dealing with these dependencies is a very annoying thing. I'm not afraid of anything, I'm afraid of trouble ~ :!:

For PHP, php-fpm is still the most suitable, spawn-fcgi and other things do not have to consider, I prefer to use the FastCGI Server built in PHP5.

Start the server and listen on port 9000 by issuing the following command:

php-cgi -q -b 127.0.0.1:9000 &

OK, with nginx, you can continue to work, but you will find that every once in a while there will be a 502 Bad Gateway error, because the php-cgi process has reached the maximum number of requests (default 500) automatically quit.

You need to set two environment variables:

PHP_FCGI_CHILDREN -Number of spawned child processes

PHP_FCGI_MAX_REQUESTS -Maximum number of requests each child process can handle

With these two environment variables, start the built-in FastCGI Server, ensuring that PHP can spawn child processes to handle requests, rather than the main process. Otherwise, the situation mentioned above will occur. After reaching 500, it will automatically exit.

Here is a simple script:

#!/ bin/bash ##Reference: #### http://php.net/manual/en/install.unix.lighttpd-14.php## http://kovyrin.net/2006/05/30/nginx-php-fastcgi-howto## ## php-cgi file path PHPFCGI=`which php-cgi` ## PID file path PHP_PID="/tmp/php.pid" ##bind TCP address FCGI_BIND_ADDRESS="127.00.0.1:9000" ##Bind to Unix domain socket#FCGI_BIND_ADDRESS="/tmp/php.sock" ##How many PHP child processes are spawned ##excluding the main process PHP_FCGI_CHILDREN=16 ##Maximum number of requests processed by each PHP process PHP_FCGI_MAX_REQUESTS=4096 ##User USERID=verdana ##################then CMD="/bin/su -m -c \"$PHPFCGI -q -b $FCGI_BIND_ADDRESS\" $USERID"else CMD="$PHPFCGI -b $FCGI_BIND_ADDRESS"fi echo $CMD #Related environmental variables E="PHP_FCGI_CHILDREN=$PHP_FCGI_CHILDREN PHP_FCGI_MAX_REQUESTS=$PHP_FCGI_MAX_REQUESTS" #Ignore other environment variables and start nohup env - $E sh -c "$CMD" &> /dev/null & #Record PID# $! of PHP main process in a clean environment PID#Find the smallest PID of all php-cgi processes, which is the PIDMASTER_PID=`ps -e of the main process| grep 'php-cgi' | sed -n '1p' | awk '{print $1}'`echo $MASTER_PID > "$PHP_PID"

How do I close it?

It can kill all php-cgi processes at once:

ps -e | grep php-cgi | awk '{print $1}' | xargs kill

Killing only the main process will achieve the same effect, and all child processes will disappear:

cat /tmp/php.pid|xargs kill Thank you for reading this article carefully, I hope Xiaobian shared "Shell script how to start PHP built-in FastCGI Server" This article is helpful to everyone, but also hope that everyone supports more, pay attention to the industry information channel, more relevant knowledge waiting for you to learn!
