Как да сменим името на интерфейса от ens3а0 на eth0

Posted on септември 15, 2017 | by linuxbg | 1 коментар

Досадното сменяне на интерфейса трови живота на много хора, в новите версии на Debian, Ubuntu и другите дебиан базирани се наблюдава масово мрежовият интерфейс да има име от рода на ens3а0 и сходни. Тук описвам кратка процедура за смяна на името на интерфейса. Започваме.

Отиваме в конфигурацията на grub

nano /etc/default/grub

1	nano /etc/default/grub

там намираме следния ред

GRUB_CMDLINE_LINUX=""

1	GRUB_CMDLINE_LINUX=""

променяме го да стане

GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"

1	GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"

след което конфигурираме наново

grub-mkconfig -o /boot/grub/grub.cfg

1	grub-mkconfig -o /boot/grub/grub.cfg

после отива и си сменяме имената на интерфеисите в interfaces

nano /etc/network/interfaces

1	nano /etc/network/interfaces

auto ens33
iface ens33 inet dhcp

на 

auto eth0
iface eth0 inet dhcp

auto ens33

iface ens33 inet dhcp

на

auto eth0

iface eth0 inet dhcp

и накрая да не забравим reboot

Ubuntu 15.10 LAMP server tutorial with Apache 2.4, PHP 5 and MariaDB (instead of MySQL)

Posted on ноември 5, 2015 | by linuxbg | Leave a Comment

LAMP is short for Linux, Apache, MySQL, PHP. This tutorial shows how you can install an Apache 2 web server on an Ubuntu 15.10 (Wiley Werewolf) server with PHP 5.6 (mod_php) and MySQL support. Additionally, I will install PHPMyAdmin to make MySQL administration easier. A LAMP setup is the perfect basis for CMS systems like Joomla, WordPress or Drupal.

The Perfect Server – Ubuntu 15.10 with Apache, PHP, MySQL, PureFTPD, BIND, Postfix, Dovecot and ISPConfig 3

Posted on ноември 5, 2015 | by linuxbg | Leave a Comment

This tutorial shows the installation of an Ubuntu 15.10 (Wily Werewolf) web hosting server with Apache2, Postfix, Dovecot, Bind and PureFTPD to prepare it for the installation of ISPConfig 3. The resulting system will provide a Web, Mail, Mailinglist, DNS and FTP Server.

ISPConfig 3 is a web hosting control panel that allows you to configure the following services through a web browser: Apache or nginx web server, Postfix mail server, Courier or Dovecot IMAP/POP3 server, MySQL, BIND or MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more. This setup covers the installation of Apache (instead of Nginx), BIND (instead of MyDNS), and Dovecot (instead of Courier).
