ubuntu修改apache2的默认访问端口

apache2的默认访问端口为80，但是在某些特殊情况和特殊网络状态下，80端口可能无法使用。这时，我们就需要对80默认端口进行更改（修改为8001端口），具体更改步骤如下：

1.进入apache2安装目录下（如果使用ubuntu命令安装，其安装目录在/etc/apache2/）

2.修改ports.conf  文件

# If you just change the port or add more ports here, you will likely also

# have to change the VirtualHost statement in

# /etc/apache2/sites-enabled/000-default.conf

Listen 8001

#Listen 80

<IfModule ssl_module>

        Listen 443

</IfModule>

<IfModule mod_gnutls.c>

        Listen 443

</IfModule>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

3.进入sites-available目录下，修改000-default.conf文件

<VirtualHost *:8001>

#<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

        ServerAdmin webmaster@localhost

        DocumentRoot /var/www/html

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,

        # error, crit, alert, emerg.

        # It is also possible to configure the loglevel for particular

        # modules, e.g.

        #LogLevel info ssl:warn

        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>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

4.最好重启一下apache2服务
