1. 打开  apache安装目录/conf/httpd.conf 配置文件
2. 搜索Listen监听端口，修改如下

#

# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 12.34.56.78:80

# 监听80端口，允许所有ip访问

# 与 Listen 0.0.0.0:80 等效

Listen 80

记得重启 apache 服务器

配置apache允许所有ip访问
