重新安装nginx后无法进入nginx欢迎页面

当我第一次安装nginx时，我能够使用服务器的ip（rackspace云服务器）访问“欢迎使用nginx”索引页面。长话短说，我不得不重新安装nginx，但在重新安装nginx之后，我再也无法访问nginx欢迎页面

我已经多次停止和启动了nginx，并重新启动了服务器，但都不起作用。 “站点可用”中的默认文件不应该在每个instal上都相同吗

以下是来自可用站点的默认文件的内容：

# You may add here your
# server {
#   ...
# }
# statements for each of your virtual hosts to this file

##
# You should look at the following URL's in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.
# http://wiki.nginx.org/Pitfalls
# http://wiki.nginx.org/QuickStart
# http://wiki.nginx.org/Configuration
#
# Generally, you will want to move this file somewhere, and start with a clean
# file but keep this around for reference. Or just disable in sites-enabled.
#
# Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.

您是否收到网络错误或nginx错误页面？您是否在服务器上启用了防火墙？此外，站点是否已符号链接到

站点已启用/

？否我看不到任何网络错误，并且除了取消安装和重新安装nginx之外，我没有对服务器进行任何其他更改。说到这一点，你必须原谅我的noob-ishnest，我做前端开发的时间最长，对服务器管理从来没有真正认真过。不幸的是，没人担心，每个人都从某个地方开始：-）我只是想缩小可能性。当你将浏览器指向你的站点时，你实际上看到了什么？这是无法从浏览器连接到服务器的屏幕（“哎呀！谷歌浏览器无法连接到”在Chrome中），我觉得有点傻。该网站没有符号链接（只是知道这意味着什么），一旦我这样做，它的功能正常。生活和学习。
