Ubuntu部署Apache2服务器遇异常：127.0.1.1无法访问及配置提示

1. 修正虚拟主机配置的错误 #

你的虚拟主机配置存在两处明显问题：

• 示例行ServerName www.example.com末尾多了一个多余的反引号`，会导致Apache解析配置失败
• 同一个<VirtualHost *:80>块里重复定义了ServerName，虽然Apache会以最后一个为准，但这种写法属于不良配置，建议直接注释或删除无用的示例行

另外，要让127.0.1.1能正常访问，需将该IP添加到虚拟主机的ServerAlias中。修改后的完整配置如下：

<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
# ServerName www.example.com  # 注释或删除该行示例配置

ServerAdmin myemail@gmail.com
ServerName mydomain.com
ServerAlias server.mydomain.com 127.0.1.1  # 新增127.0.1.1作为访问别名
DocumentRoot /media/balkanflix/SERIJALI/Balkanflix

<Directory /media/balkanflix/SERIJALI/Balkanflix>
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all granted
    </Directory>

ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined

# For most configuration files from conf-available/, which are
# enabled or disabled at a global level, it is possible to
# include a line for only one particular virtual host. For example the
# following line enables the CGI configuration for this host only
# after it has been globally disabled with "a2disconf".
#Include conf-available/serve-cgi-bin.conf
</VirtualHost>

2. 解决全局ServerName缺失的问题 #

执行sudo apachectl configtest时出现的AH00558提示，是因为Apache无法自动识别服务器的完全限定域名，需要在全局配置中添加ServerName指令：

• 打开Apache全局配置文件：/etc/apache2/apache2.conf
• 在文件末尾添加一行：

ServerName 127.0.1.1

如果你的域名已指向该服务器，也可以填写域名mydomain.com

3. 验证配置并重启服务 #

修改完成后，先执行配置检测确认语法正确：

sudo apachectl configtest

当返回Syntax OK时，重启Apache服务：

sudo systemctl restart apache2

4. 测试访问 #

此时再访问http://127.0.1.1/，即可正常加载你的动漫流媒体网站内容。

问题根源说明 #

静态IP 192.168.1.100能正常访问，是因为Apache会默认匹配第一个符合<VirtualHost *:80>规则的虚拟主机；而127.0.1.1未被配置在虚拟主机的ServerName或ServerAlias中，Apache找不到对应的主机配置，因此返回无法访问。
