I am trying to install fast-cgi for nginx on an EC2 instance. I followed the steps explained here, but that is meant for Debian and does not work out of the box for a red-hat based system. I modified the script a bit to look like -

#!/bin/bash
### BEGIN INIT INFO
# Provides: php-fcgi
# Required-Start: $nginx
# Required-Stop: $nginx
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: starts php over fcgi
# Description: starts php over fcgi
### END INIT INFO

. /etc/rc.d/init.d/functions

(( EUID )) && echo .You need to have root priviliges.. && exit 1
BIND=/tmp/php.socket
USER=nginx
PHP_FCGI_CHILDREN=15
PHP_FCGI_MAX_REQUESTS=1000

PHP_CGI=/usr/bin/php-cgi
PHP_CGI_NAME=`basename $PHP_CGI`
PHP_CGI_ARGS="- USER=$USER PATH=/usr/bin PHP_FCGI_CHILDREN=$PHP_FCGI_CHILDREN PHP_FCGI_MAX_REQUESTS=$PHP_FCGI_MAX_REQUESTS $PHP_CGI -b $BIND"
RETVAL=0

start() 
 echo -n "Starting PHP FastCGI: "
 #ORIGINAL LINE
 #daemon $PHP_CGI --quiet --start --background --chuid "$USER" --exec /usr/bin/env -- $PHP_CGI_ARGS
 #MODIFIED LINE
 daemon --user=$USER $PHP_CGI -b $BIND&
 RETVAL=$?
 echo
 [ $RETVAL -eq 0 ] && touch /var/lock/subsys/php-fcgi
 #echo "$PHP_CGI_NAME."

stop() 
 echo -n "Stopping PHP FastCGI: "
 killall -q -w -u $USER $PHP_CGI
 RETVAL=$?
 echo "$PHP_CGI_NAME."
 rm /var/lock/subsys/php-fcgi


case "$1" in
 start)
 start
 ;;
 stop)
 stop
 ;;
 restart)
 stop
 start
 ;;
 *)
 echo "Usage: php-fastcgi restart"
 exit 1
 ;;
esac
exit $RETVAL

The problem I have now is -

1. 
   service php-fcgi start keeps the shell blocked. If I run service php-fcgi start & and then ps aux, I see the php-cgi process running bound to the socket. I see the start command stop only when I execute service php-fcgi stop. How do I solve this blocking issue? I have tried adding an & at the end of the line spawning the daemon. But other scripts do not seem to be doing this.
   This is the most complicated script I am attempting to modify yet :-(


2. How do I get the script to display the green [ OK ]? I checked scripts like httpd and saw that all they were doing was something as shown below. But I never see a green [ OK ] when I execute php-fcgi. I also discovered that putting echo_success with functions sourced displays the green [ OK ] but I do not see any other scripts in the /etc/rc.d/init.d/ executing echo_success or echo_failure. What have I got wrong?


3. Also, How do i specify PHP_FCGI_CHILDREN with daemon?

echo
 [ $RETVAL -eq 0 ] && touch /var/lock/subsys/

1. 
   

   Change the daemon line to:

   
   
   

   daemon --user $USER --pidfile=$PIDFILE "$PHP_CGI -b $BIND &> /dev/null &"
   

   
   
   

   &> /dev/null is equipvalent to >/dev/null 2>&1, means that
   redirect both stdout and stderr to /dev/null.

   
   


2. 
   

   If that doesn't show the [ OK ] flag, try this:

   
   
   

   if [ -n "$pid" ]; then
    echo $pid > $PIDFILE
    success "Starting php-cgi service"
   else
    failure "Starting php-cgi service"
   fi
   

   
   
   

   Take a look at the success function in the /etc/init.d/functions
   for more details.

   
   
   

   The stop function should change to:

   
   
   

   killproc -p $PIDFILE $PHP_CGI_NAME
   

   
   


3. 
   

   Insert the PHP_CGI_ARGS as an environment variable to the daemon function:

   
   
   

   daemon --user $USER --pidfile=$PIDFILE "env - $PHP_CGI_ARGS
$PHP_CGI -b $BIND &> /dev/null &"

   
   

Moreover, to make it start automatically at boot, you should change the init info to the Red Hat based style:

# chkconfig: 345 85 15
# description: Running php-cgi
# processname: php-cgi
# config: /etc/sysconfig/php-cgi

So, you're on a redhat based system, and you want a version of PHP that comes with FPM (the best way to do cgi on PHP >= 5.3)? Why don't you just install the packages from somewhere like IUS: http://iuscommunity.org/ , rather then trying to get a custom-built version working? The repository will allow you to stay up to date a lot easier, and will generally make your life easy.

Once the repo is installed, this is all you'd need to do: chkconfig php-fpm start; service php-fpm start, and you'll be all set.
