I am totally new to ubuntu server(did not work with any server before). I have installed LAMP(apache2, mysql, php) on ubuntu server(16.04.1 LTS). It works all correctly. It has 192.168.0.22 Ip.

On other computers, there are windows 7 installed(192.168.0.45).

When i write ubuntu server's ip in windows browser, it works but when i write localhost on windows browser it does not work but it does work on ubuntu server.

So now I want to set custom/static ip on ubuntu server this 192.168.0.11 its totally does not work neither in ubuntu server browser or neither ping neither ping

my /etc/network/interfaces is something like this

source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto enp2s0
iface enp2s0 inet dhcp

I dont have eth0. I did everything to find it but did not find

How i tried to change ubuntu server ip to static

# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto enp2s0
iface enp2s0 inet static address 192.168.0.11 netmask 255.255.255.0 #<-- random i dont know what should i have to write here gateway 192.168.0.1 #<-- random i dont know what should i have to write here network 192.168.0.10 #<-- random i dont know what should i have to write here broadcast 192.168.0.12 #<-- random i dont know what should i have to write here nameserver 8.8.8.8 #<-- random i dont know what should i have to write here

my /etc/hosts

127.0.0.1 localhost
127.0.1.1 web
#The following lines are desirable for IPv6 capable host
::1 localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

Repeat I dont have etho

Command :

root@web: # ipconfig -a
enp0s25 Link encap:Ethernet hwaddr ....... broadcast MULTICAST MTU:15000..... ... 0... 0...0 .. ................................. .................................
enp2s0 Link encap:ethernet hwaddr ....... inet addr:192.168.0.22 bcast :192.168.0.255 mask 255.255.255 inet6 addr fe80::..:... ........................... ........................... ...........................
lo link encap:local Loopback inet addr:127.0.0.1 Mask :255.0.0.0 inet6 addr: ::1/128 Scope:host UP LOOPBACK RUNNING MTU :numbera rx pckts :228 bla bla bal .......... ..........

I have put almost all information. If you need any further information tell me. Ty for helping.

I suggest you amend the file /etc/network/interfaces to read:

# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto enp2s0 iface enp2s0 inet static address 192.168.0.10 netmask 255.255.255.0 gateway 192.168.0.181 dns-nameservers 8.8.8.8

Get the system to re-read and use the changes:

sudo ifdown enp2s0 && sudo ifup -v enp2s0

The -v for verbose should produce some output that tells us if the address was given successfully. Test:

ping -c3 192.168.0.181
ping -c3 8.8.8.8
ping -c3 

If you get ping returns, you are all set.

You can use the following

# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto enp2s0 iface enp2s0 inet static address 192.168.0.10 netmask 255.255.255.0 #depends on your network class of address gateway 192.168.0.1 #address of the server that allow you to connect internet or other networks. dns-nameservers 8.8.8.8 #domain names resolver 8.8.8.8 it's google's public dns

then

$ sudo touch /etc/network/interfaces.d/enp2s0

then

$ sudo ifdown enp2s0 && sudo ifup enp2s0
