Question

我在ubuntu中安装了memcached，我想在系统启动时将memcache设置为自动启动，但是我出错了！我在/etc/init.d/中创建了一个名为memcached的shell脚本，这是我的代码：

#! /bin/sh
#
# processname: memcached
# config: /etc/sysconfig/memcached

# Source function library - for other linux
#. /etc/rc.d/init.d/functions
# Source function library - for suse linux

#load the public function used by all shell scripts
. /lib/lsb/init-functions

PORT=11211
USER=root
#最大连接数，根据实际需求修改
MAXCONN=1024
#最大内存量，单位M
CACHESIZE=128
OPTIONS=""

if [ -f /etc/sysconfig/memcached ];then
  . /etc/sysconfig/memcached
fi

# Check that networking is up.
if [ "$NETWORKING" = "no" ]
then
then
  exit 0
fi

RETVAL=0
prog="memcached"
start () {
  echo -n $"Starting $prog: "
  # insure that /usr/local/memcached has proper permissions
  chown $USER /usr/local/memcached
  /usr/local/memcached/bin/memcached -d -p $PORT -u $USER  -m $CACHESIZE -c $MAXCONN -P /usr/local/memcached/memcached.pid $OPTIONS
  RETVAL=$?
  echo
  [ $RETVAL -eq 0 ] && touch /var/lock/subsys/memcached
}
stop () {
  echo -n $"Stopping $prog: "
  killproc memcached
  RETVAL=$?
  echo
  if [ $RETVAL -eq 0 ] ; then
  rm -f /var/lock/subsys/memcached
  rm -f /usr/local/memcached/memcached.pid
  fi
}

restart () {
  stop
  start
}

# See how we were called.
case "$1" in
  start)
  start
  ;;
  stop)
  stop
  ;;
  status)
  status memcached
  ;;
  restart|reload)
  restart
  ;;
  condrestart)
  [ -f /var/lock/subsys/memcached ] && restart || :
  ;;
  *)
  echo $"Usage: $0 {start|stop|status|restart|reload|condrestart}"
  exit 1
esac

exit $?

然后我在执行

时向该文件添加执行权限

chkconfig --add memcached

问题出现了，它说：

问题是chkconfig更像是一个Redhat-ism，你可以在Ubuntu上安装（看起来像你有）。但是，看起来这里的许多依赖项（即启动脚本）都已从此迁移到Upstart上，因此使用此系统最多也是困难的。

对于Ubuntu，您可能需要create an upstart script。请注意，最近Ubuntu将来会decided移至systemd。

或者，请查看更加友好的Ubuntu sysv-rc-conf（有关详情，请参阅this Askubuntu post）。
