我怎么能重新启动nginx服务器上的spawn-fcgi？
运行选项-P将PID存储在某个临时文件中。 例如：
/usr/local/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -P /var/run/fcgi.pid
那么你可以通过这个pid杀死它：
kill -9 `cat /var/run/fcgi.pid`
spawn-fcgi的过程是如何开始的，是通过命令行（手动）还是使用rc脚本。 无论哪种情况，您都可以通过首先findPID来终止进程
使用命令ps aux | grep spawn-fcgi来定位进程和命令kill -9 PID
我build议slashdotbuild议使用rc脚本来启动和结束spawn-fcgi进程。
更新：这个答案随机失败了我（我不知道为什么），但我要离开这里，因为它可能有助于某人。
killall -9 -w php-cgi
“-w”等待。 因为如果你试图（重新）很快（没有延迟）重新启动spawn-fcgi，spawn-fcgi总是给我错误，就像“…已经在使用”一样。 （我不记得确切的错误，对不起。）但是，如果你打算把它放在cron中，“-w”不能100％的工作。 经过几个月的随机php故障，我决定切换到php-fpm，它有自己独特的问题 – 谨慎行事。
我更喜欢使用主pipe来进行这种stream程pipe理： http : //supervisord.org/
主pipe会“挂在你的进程上”：它会根据需要重新启动，pipe理stdout / stderr日志logging，并给你一个明确的命令来pipe理进程，而不必混淆PID文件等。
尝试这个：
