我似乎在启动时自动执行某些服务时遇到了一些问题。我以前也遇到过这个问题,但我找不到导致这个问题的确切原因。
我已将这两项服务添加到启动中:
$ sudo update-rc.d sickbeard defaults
然后:
$ sudo service sickbeard status
* sickbeard is not running
$ sudo service sabnzbdplus status
* SABnzbd+ binary newsgrabber: not running
$ service --status-all
[ + ] acpid
[ - ] rsync
[ + ] rsyslog
[ - ] sabnzbdplus
[ + ] saned
[ ? ] sendsigs
[ - ] sickbeard
(列表被截断)来自 jobs-admin 的屏幕截图:
如您所见,应用程序并未在启动时启动...这可能是什么原因造成的?
答案1
最后我们发现,虽然sickbeard
在开机时启动,但是却失败了。
我们/var/log/boot.log
可以看到这个错误:
Starting SickBeard
/usr/bin/python: can't open file 'SickBeard.py': [Errno 2] No such file or directory
并查看sickbeard
初始化脚本:
APP_PATH=${SB_HOME-/opt/sickbeard}
由于某种我们不知道的原因,何时sickbeard
开始,/opt
还没有准备好。
作为解决方法,sickbeard
在启动过程中稍后启动似乎可以解决问题。
为了实现这一点,请查看/etc/rcX.d
文件夹并删除Sxxsickbeard
和Kxxsickbeard
文件。这些是脚本的符号链接/etc/init.d/sickbeard
。
该脚本在系统启动时按照字母顺序执行,因此使用update-rc.d
它可以选择“何时”启动/停止服务,例如:
update-rc.d sickbeard start 99 2 3 4 5 . stop 01 0 1 6 .
这将在系统启动期间分配S99
(最后一个可能的) ,并在关机或重启期间分配(第一个可能的) 。start
K01
stop
在这种情况下,看看你的运行级别,我建议这样的配置:
update-rc.d sickbeard start 06 2 3 4 5 . stop 01 0 1 6 .
答案2
好的,我找到了导致此问题的原因。也许其他人也遇到了同样的问题。
我的磁盘已加密,因此只有登录后才可读取。所有程序配置都在 /home/username 中,因此不可读取。这导致服务出现故障。
我写的修复程序:
#!/bin/bash -vx
DIR=/home/mainstream/.sabnzbd
sleep 10
function checkdir() {
if [ ! -d "$DIR" ];
then
echo "File $DIR doesn't exist yet"
sleep 5 && checkdir #loop to check if directory is ready
else
echo "Directory $DIR exists"
/etc/init.d/sabnzbdplus start && /etc/init.d/sickbeard start && /etc/init.d/autosub start && /etc/init.d/couchpotatov2 start
fi
}
checkdir
它会检查文件夹是否存在(每 5 秒一次)并相应地启动服务。添加它(例如添加到 rc.local)。示例 rc.local:
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
sleep 10
exec 2> /tmp/rc.local.log # send stderr from rc.local to a log file
exec 1>&2 # send stdout to the same log file
set -x # tell sh to display commands before execution
#/home/mainstream/.startup.sh
/opt/startup.sh
exit 0
脚本输出:

+ checkdir
