# check_fastcgi.pl checks if a php-cgi server (or, theorically, any
# other fastcgi server) is alive.

先使用cpan安装


strict
FCGI::Client
IO::Socket::INET
Getopt::Long


建立一个/tmp/test.php文件
echo "ok" ;
?>




测试 脚本 ：
./check_fastcgi.pl -H 127.0.0.1 -p 9000 -s /tmp/test.php -e ok
OK: fastcgi server is working


配置：
我对脚本进行了修改。指定了文件的目录。
可根据个人情况进行修改
my $host = '';         # server host
my $port = 9999;       # tcp port
my $script = '';       # test script (absolute path starting at / - root directory -)
my $query_string = ''; # query string
my $expected = 'OK';   # expected string
my $timeout = 5;       # timeout in seconds
