当我尝试重新启动apache发布/etc/init.d/apache2 restart时,我收到以下消息:

root@server:~# /etc/init.d/apache2 restart
 * Restarting web server apache2                                                                                                                             apache2: apr_sockaddr_info_get() failed for server

我需要一个解决方案来删除第一个字段是IPv4地址的重复行.例如,我在文件中有以下行:

192.168.0.1/text1/text2
192.168.0.18/text03/text7
192.168.0.15/sometext/sometext
192.168.0.1/text100/ntext
192.168.0.23/othertext/sometext

因此,在上一个场景中它匹配的只是IP地址.我所知道的是IP地址的正则表达式是:

\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b

如果解决方案是一条线并且尽可能快,那将是很好的.
