网站用nginx在跑，网站经常疑似被挂掉，只因没钱买了个便宜的VPS，米国滴，经常被重启，为毛？米国也有G党？有木有？有木有？太坑爹了！

解决办法是把nginx添加到启动项中去，在 /etc/init.d/ 目录下添加 nginx 文件：
root@ubuntu: /etc/init.d/# vim nginx

#! /bin/sh
# chkconfig: - 58 74
# description: nginx is the Nginx daemon. 
# Description: Startup script for nginx webserver on Debian. Place in /etc/init.d and
# run 'sudo update-rc.d nginx defaults', or use the appropriate command on your
# distro.

set -e 
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DESC="nginx daemon"
NAME=nginx
DAEMON=/usr/local/nginx/sbin/$NAME
CONFIGFILE=/usr/local/nginx/conf/nginx.conf 
PIDFILE=/usr/local/nginx/logs/$NAME.pid
SCRIPTNAME=/etc/init.d/$NAME 
# Gracefully exit if the package has been removed.
test -x $DAEMON || exit 0 
d_start() {
  $DAEMON -c $CONFIGFILE || echo -en "\n already running"
} 
d_stop() {
  kill -QUIT `cat $PIDFILE` || echo -en "\n not running"
} 
d_reload() {
  kill -HUP `cat $PIDFILE` || echo -en "\n can't reload"
} 
case "$1" in
  start)
    echo -n "Starting $DESC: $NAME"
    d_start
        echo "."
  ;;
  stop)
    echo -n "Stopping $DESC: $NAME"
    d_stop
        echo "."
  ;;
  reload)
    echo -n "Reloading $DESC configuration..."
    d_reload
        echo "."
  ;;
  restart)
    echo -n "Restarting $DESC: $NAME"
    d_stop
    # One second might not be time enough for a daemon to stop,
    # if this happens, d_start will fail (and dpkg will break if
    # the package is being upgraded). Change the timeout if needed
    # be, or change d_stop to have start-stop-daemon use --retry.
    # Notice that using --retry slows down the shutdown process
    # somewhat.
    sleep 1
    d_start
    echo "."
  ;;
  *)
    echo "Usage: $SCRIPTNAME {start|stop|restart|reload}" >&2
    exit 3
  ;;
esac 
exit 0

root@ubuntu: /etc/init.d/# chmod +x nginx
root@ubuntu: /etc/init.d/# update-rc.d nginx defaults

好像到这里就完事了...

查看一下
root@ubuntu: chkconfig --list
...
nginx                     0:off  1:off  2:on   3:on   4:on   5:on   6:off
...
