Tomcat服务器启动但是http：//localhost：8080或者127.0.0.1：8080打不开的解决办法

如果你在别的文章尝试了那几种方式无效的话可以试试我的方法。
如果你可以正常启动Tomcat，配置环境也没问题，端口号也改过，端口也未被占用，而且webapps/examples/index.html文件也存在的话，考虑是否修改过hosts文件。

本人曾经为了下游戏加速曾经修改过hosts文件。
文件位置在C:\WINDOWS\system32\drivers\etc\hosts
文件的默认内容为

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost

可以把hosts文件复制到桌面，用记事本打开，把代码复制进去，再把文件复制到原来的位置，覆盖即可。
然后就能打开啦！
