Question

如何启动多个守护进程，它们是“非”实例，它们是不同的守护进程。我已经使用了以下脚本，但是在停止守护进程并重新启动后，upstart会在启动时挂起。

#ubuntu upstart script for antkorp services 
description "Antkorp colloboration and communication platform"
author "www.antkorp.in"

task
start on runlevel [2345]
stop  on runlevel [016]

pre-start script
        logger -t "antkorp:" "antkorp platform booting...";
end script

post-start script
        logger -t "antkorp:" "antkorp platform started successfully.";
end script

pre-stop script
        logger -t "antkorp:" "antkorp platform stopping..";
end script

post-stop script
        logger -t "antkorp:" "antkorp platform stopped successfully.";
end script

这是守护进程的init文件。

description     "antkorp gw daemon"

start on starting akorp
stop on stopping akorp

expect fork
respawn

pre-start script
logger -t "gw:" "antkorp gw daemon about to start.";
end script

exec /home/rk/gw

post-start script
logger -t "gw:" "antkorp gw daemon started successfully.";
end script

pre-stop script
logger -t "gw:" "antkorp gw daemon stopping ...";
end script

post-stop script
logger -t "gw:" "antkorp gw daemon stopped.";
end script

手动'停止'工作正常，但'开始'挂起。请指教。

这是守护进程源代码。

#include<stdio.h>
#include<unistd.h>
#include<signal.h>
#include<stdlib.h>

void 
sigterm_handler(int signo)
{
    exit(1);
    return;
}

int 
main(int ac, char **av) 
{
    signal(SIGTERM, sigterm_handler);
    daemon(0,0); 
    while(1) sleep(1); 
    return 0; 
}

经过多次试验和错误后，我终于解决了这个问题。从主脚本“akorp.conf”文件中删除“task”关键字可以解决问题。

用upstart启动和停止多个守护进程
