Nginx Init.d 脚本

嘿，我需要一些有关 Nginx 的 Init.d 脚本的帮助 这是我的 Nginx 文件位置 -

  nginx path prefix: "/usr/local/nginx"  nginx binary file: "/usr/local/nginx/nginx"
  nginx configuration prefix: "/usr/local/nginx"
  nginx configuration file: "/usr/local/nginx/nginx.conf"
  nginx pid file: "/usr/local/nginx/nginx.pid"
  nginx error log file: "/usr/local/nginx/logs/error.log"
  nginx http access log file: "/usr/local/nginx/logs/access.log"

这是我的 Init.d 脚本 -

#! /bin/sh

### BEGIN INIT INFO

# Required-Start:    $all
# Required-Stop:     $all
# Default-Start:     2 3 4 5

# Short-Description: starts the nginx web server
# Description:       starts nginx using start-stop-daemon
### END INIT INFO

PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DAEMON=/usr/local/nginx/nginx
NAME=nginx
DESC=nginx

test -x $DAEMON || exit 0

# Include nginx defaults if available
if [ -f /usr/local/nginx/nginx ] ; then
        . /usr/local/nginx/nginx
fi

set -e

case "$1" in
  start)
        echo -n "Starting $DESC: "
        start-stop-daemon --start --quiet --pidfile /usr/local/nginx/nginx.pid \
                --exec $DAEMON -- $DAEMON_OPTS
        echo "$NAME."
        ;;
  stop)
        echo -n "Stopping $DESC: "
        start-stop-daemon --stop --quiet --pidfile /usr/local/nginx/nginx.pid \
                --exec $DAEMON
        echo "$NAME."
        ;;
  restart|force-reload)
        echo -n "Restarting $DESC: "
        start-stop-daemon --stop --quiet --pidfile \
                /usr/local/nginx/nginx.pid --exec $DAEMON
        sleep 1
        start-stop-daemon --start --quiet --pidfile \
                /usr/local/nginx/nginx.pid --exec $DAEMON -- $DAEMON_OPTS
        echo "$NAME."
        ;;
  reload)
      echo -n "Reloading $DESC configuration: "
      start-stop-daemon --stop --signal HUP --quiet --pidfile /usr/local/nginx/nginx.pid \
          --exec $DAEMON
      echo "$NAME."
      ;;
  *)
        N=/etc/init.d/$NAME
        echo "Usage: $N {start|stop|restart|force-reload}" >&2
        exit 1
        ;;
esac

exit 0

我尝试修改它以适应我的文件位置，但它仍然不起作用，我需要做哪些更改才能使其工作？

我已经为 Gentoo 编写了这个（最初从 debian 接管）并且我建议使用它因为它有效并且具有更好的调试输出：

#!/bin/bash
echo "Script executed from: ${PWD}"

BASEDIR=$(dirname $0)
echo "Script location: ${BASEDIR}"

nginx="/usr/sbin/nginx"
prog=$(basename $nginx)

NGINX_CONF_FILE="${PWD}/../cfg/nginx.conf"

echo "Using config file: ${NGINX_CONF_FILE} "

PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DAEMON=/usr/sbin/nginx

PS="nginx"
PIDNAME="nginx"             #lets you do $PS-slave
PIDFILE=$PIDNAME.pid                    #pid file
PIDSPATH=/var/run

DESCRIPTION="Nginx Server..."

SCRIPT_ERROR=1                          #ala error codes
TRUE=1                                  #boolean
