Question

我是运行Debian 6的新Linode / Linux用户。我试图让我的Unicorn服务器在启动时启动，但由于某种原因它不是，我无法追踪任何错误消息。 Nginx开始很好，我有一个多用户RVM安装。我的直觉是与RVM有关。这是unicorn_init.sh中的/rails/todo文件，/etc/init.d/unicorn处有一个符号链接：

# unicorn_init.sh
#!/bin/sh

set -e

TIMEOUT=${TIMEOUT-60}
APP_ROOT=/rails/todo
PID=$APP_ROOT/tmp/pids/unicorn.pid
CMD="$APP_ROOT/bin/unicorn_rails -D -c $APP_ROOT/config/unicorn.rb -E production"
GEM_HOME="/usr/local/rvm/gems/ruby-1.9.2-p290@global"
action="$1"
set -u

old_id="$PID.oldbin"

cd $APP_ROOT || exit 1
export GEM_HOME=$GEM_HOME

sig () {
  test -s "$PID" && kill -$1 `cat $PID`
}

oldsig () {
  test -s $old_pid && kill -$1 `cat $old_pid`
}

case $action in
  start)
    sig 0 && echo >&2 "Already running" && exit 0
    su -c "$CMD" - root
    ;;
  stop)
    sig QUIT && exit 0
    echo >&2 "Not running"
    ;;
  force-stop)
    sig TERM && exit 0
    echo >&2 "Not running"
    ;;
  restart|reload)
    sig HUP && echo reloaded OK && exit 0
    echo >&2 "Couldn't reload, starting '$CMD' instead"
    su -c "$CMD" - root
    ;;
  upgrade)
    if sig USR2 && sleep 2 && sig 0 && oldsig QUIT
    then
      n=$TIMEOUT
      while test -s $old_pid && test $n -ge 0
      do
        printf '.' && sleep 1 && n=$(( $n - 1 ))
      done
      echo

      if test $n -lt 0 && test -s $old_pid
      then
        echo >&2 "$old_pid still exists after $TIMEOUT seconds"
        exit 1
      fi
      exit 0
    fi
    echo >&2 "Couldn't upgrade, starting '$CMD' instead"
    su -c "$CMD" - root
    ;;
  reopen-logs)
    sig USR1
    ;;
  *)
    echo >&2 "Usage: $0 <start|stop|restart|upgrade|force-stop|reopen-logs>"
    exit 1
    ;;
esac

我99％的方式让我的设置工作 - 任何建议都会非常感激。

以下是$ update-rc.d unicorn defaults的输出：

update-rc.d: using dependency based boot sequencing
insserv: warning: script 'unicorn' missing LSB tags and overrides
insserv: There is a loop between service nginx and unicorn if stopped
insserv:  loop involving service unicorn at depth 2
insserv:  loop involving service nginx at depth 1
insserv: Stopping unicorn depends on nginx and therefore on system facility `$all' which can not be true!
insserv: exiting now without changing boot order!
update-rc.d: error: insserv rejected the script header

Answer 1

update-rc.d：error：insserv拒绝了脚本标题

文件的开头如下：

# unicorn_init.sh
#!/bin/sh

shebang行（#!/bin/sh）必须是文件的第一行。

我无法对循环检测消息发表评论，因为我之前从未见过它。你在/etc/init.d/nginx中说的可能是表达对独角兽的依赖，但我没有在unicorn init中看到任何表达对nginx的依赖，因此循环不清楚。

insserv：警告：脚本'unicorn'缺少LSB标记和覆盖

您应该将LSB信息添加到初始脚本http://wiki.debian.org/LSBInitScripts

Linode Deban Linux + Nginx + unicorn_rails
