如何解决$DAEMON -t $DAEMON_OPT权限被拒绝的问题？

Question

I在ubuntu服务器14.04上配置nginx + meteor，地址是:http://www.andrehonsberg.com/article/install-nginx-141-meteor-js-websocket-ubuntu-1204

但是当: service nginx start时，我得到了失败：

service nginx start
Starting nginx: /etc/init.d/nginx: 26: /etc/init.d/nginx: /usr/sbin/nginx: Permission denied

这是我的nginx init脚本：

#!/bin/sh
### BEGIN INIT INFO
# Provides:          nginx
# Required-Start:    $local_fs $remote_fs $network $syslog
# Required-Stop:     $local_fs $remote_fs $network $syslog
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: starts the nginx web server
# Description:       starts nginx using start-stop-daemon
### END INIT INFO

DAEMON=/usr/sbin/nginx

# Include nginx default if available
if [ -f /etc/default/nginx ]; then
  . /etc/default/nginx
fi
test -x $DAEMON || exit 0
set -e
. /lib/lsb/init-functions
test_nginx_config() {
    if $DAEMON -t $DAEMON_OPTS >/dev/null 2>&1; then
        return 0
    else
        $DAEMON -t $DAEMON_OPTS
        return $?
    fi
}
case "$1" in
    start)
        echo -n "Starting $DESC: "
        test_nginx_config
        # Check if the ULIMIT is set in /etc/default/nginx
        if [ -n "$ULIMIT" ]; then
            # Set the ulimits
            ulimit $ULIMIT
        fi
        start-stop-daemon --start --quiet --pidfile /var/run/$NAME.pid \
            --exec $DAEMON -- $DAEMON_OPTS || true
        echo "$NAME."
        ;;
    stop)
        echo -n "Stopping $DESC: "
        start-stop-daemon --stop --quiet --pidfile /var/run/$NAME.pid \
            --exec $DAEMON || true
        echo "$NAME."
        ;;
    restart|force-reload)
        echo -n "Restarting $DESC: "
        start-stop-daemon --stop --quiet --pidfile \
            /var/run/$NAME.pid --exec $DAEMON || true
        sleep 1
        test_nginx_config
        # Check if the ULIMIT is set in /etc/default/nginx
        if [ -n "$ULIMIT" ]; then
            # Set the ulimits
            ulimit $ULIMIT
        fi
        start-stop-daemon --start --quiet --pidfile \
            /var/run/$NAME.pid --exec $DAEMON -- $DAEMON_OPTS || true
        echo "$NAME."
        ;;
    reload)
        echo -n "Reloading $DESC configuration: "
        test_nginx_config
        start-stop-daemon --stop --signal HUP --quiet --pidfile /var/run/$NAME.pid \
            --exec $DAEMON || true
        echo "$NAME."
        ;;
    configtest|testconfig)
        echo -n "Testing $DESC configuration: "
        if test_nginx_config; then
            echo "$NAME."
        else
            exit $?
        fi
        ;;
    status)
        status_of_proc -p /var/run/$NAME.pid "$DAEMON" nginx && exit 0 || exit $?
        ;;
    *)
        echo "Usage: $NAME {start|stop|restart|reload|force-reload|status|configtest}" >&2
        exit 1
        ;;
esac
exit 0

第26行是：$DAEMON -t $DAEMON_OPT

我使用azure，所以我不能使用su，我只能使用sudo，但仍然失败。如何解决这个问题？

Answer 1

只要你在你的服务器上是root/sudo，你现在在Azure上就不会面临这样的问题。

当你在azure的ubuntu上安装nginx时，仍然存在启动启动的问题。

为了在安装后启动它，我必须强制重新创建整个链接( -f是强制的)：

update-rc.d  -f nginx remove
update-rc.d  -f nginx defaults

我仍然想知道为什么..
