使用 upstart 启动 iaxmodem 和 faxmodem

iaxmodem当我有多个调制解调器时，如何使用 Upstart 启动faxgetty？ Centos 6.4 有一个很好的警告，如下所示，这使我相信标准inittab线路将不起作用。

# inittab is only used by upstart for the default runlevel.
#
# ADDING OTHER CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM.

我通常会放在哪里

IAX:2345:respawn:/path/to/iaxmodem ttyIAX

使用在运行级别更改时启动的任务来为IAXModem您想要启动的每个作业启动一个作业。然后使用任务faxgetty为每个已启动的iaxmodem作业启动一个。

IE：

init 3 -> start-iaxmodem ---> iaxmodem(ttyIAX0) -> start-faxgetty(ttyIAX0) -> faxgetty(ttyIAX0)
                          \-> iaxmodem(ttyIAX1) -> start-faxgetty(ttyIAX1) -> faxgetty(ttyIAX1)

/etc/init/start-iaxmodems.conf：

# This service starts the configured number of gettys.
start on stopped rc RUNLEVEL=[2345]

task

script
    for ttyIAX in /etc/iaxmodem/* ; do
        start iaxmodem TTY=`basename $ttyIAX`
    done
end script

/etc/init/iaxmodem.conf：

# This service maintains an iaxmodem on the sepcified device.
stop on runlevel [016]

respawn
instance $TTY
exec /usr/sbin/iaxmodem $TTY

/etc/init/start-faxgettys.conf：

# This service starts the configured number of faxgettys.
start on started iaxmodem
# this will run once per triggering iaxmodem instance
instance $INSTANCE

task

script
    # give it time to at least create the device
    /bin/sleep 1s
    start faxgetty TTY=$INSTANCE
end script

/etc/init/faxgetty.conf：

# This service maintains a faxgetty on the sepcified device.
# only stop when the stopping iaxmodem is this TTY
stop on stopping iaxmodem INSTANCE=$TTY

respawn
instance $TTY

exec /usr/sbin/faxgetty $TTY
