在网上找的脚本，挺好用的，已经用了一段时间了，怕以后配置新服务器还要再找所以记下来。

CentOS上可以用的spawn-fcgi启动脚本在网上找的支持chkconfig的spawn-fcgi启动脚本，原脚本大概是写给UNIX用的，使用的是socket文件的方式，结果启动后nginx连不上fcgi，导致PHP页面无法执行。

整好服务器后原文地址已经不知道哪里去了，真是对不起原作者。下面是在CentOS上实际测试好的启动脚本

#!/bin/sh  
#  
# Startup script for Spawn-fcgi

FCGI_SOCKET="/tmp/spawn-fcgi.sock"  
FCGI_PIDFILE="/var/run/spawn-fcgi.pid"  
PHP_FCGI_CHILDREN=4  
PHP_FCGI_MAX_REQUESTS=1000  

export PHP_FCGI_CHILDREN PHP_FCGI_MAX_REQUESTS  

RETVAL=0  
prog="spawn-fcgi"  

# Source function library.

# Source networking configuration.

# Check that networking is up.  
[ ${NETWORKING} = "no" ] && exit 0  

start() {  
        echo -n $"Starting $prog: "  
        daemon $FCGI_DAEMON -a 127.0.0.1 -p 9000 -u www -g www -f $FCGI_PROGRAM -C $PHP_FCGI_CHILDREN -P $FCGI_PIDFILE  
        RETVAL=$?  
        echo  
        [ $RETVAL -eq 0 ] && touch /var/lock/subsys/$prog  
        return $RETVAL  
}  

stop() {  
        echo -n $"Stopping $prog: "  
        rm -f $FCGI_PIDFILE $FCGI_SOCKET  
        killproc $FCGI_PROGRAM  
        RETVAL=$?  
        echo  
        [ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/$prog  
        return $RETVAL  
}  

case "$1" in  
        start)  
                start  
                ;;  
        stop)  
                stop  
                ;;  
        restart)  
                stop  
                start  
                ;;  
        condrestart)  
                if [ -f /var/lock/subsys/$prog ]; then  
                        stop  
                        start  
                fi  
                ;;  
        status)  
                status $lighttpd  
                RETVAL=$?  
                ;;  
        *)  
                echo $"Usage: $0 {start|stop|restart|condrestart|status}"  
                RETVAL=1  
esac  

exit $RETVAL  

把上面代码保存为/etc/init.d/php-fcgi，使用以下命令把spawn-fcgi加入开机启动过程：

> chkconfig --add php-fcgi  
> chkconfig --level 345 php-fcgi on  

平时停止或者重启spawn-fcgi：

> service spawn-fcgi stop  
> service spawn-fcgi start  
> service spawn-fcgi restart
