This post will show the step to set the hostname and configure static IP address to the server. DHCP is not recommended if you plan to run this fedora 20 as a server. By default in Fedora 20, ifconfig command is not installed automatically. You should install net-tools package, it includes ifconfig and netstat.
ifconfig not installed by default :
[root@localhost ~]# ifconfig -bash: ifconfig: command not found
1. Install net-tools, it will include ifconfig :
[root@localhost ~]# yum install net-tools -y fedora/20/x86_64/metalink | 8.7 kB 00:00:01 fedora | 3.8 kB 00:00:01 updates/20/x86_64/metalink | 5.0 kB 00:00:00 updates | 4.9 kB 00:00:00 (1/4): fedora/20/x86_64/group_gz | 394 kB 00:00:37 (2/4): updates/20/x86_64/group_gz | 394 kB 00:00:43 (3/4): updates/20/x86_64/primary_db | 8.8 MB 00:03:22 (4/4): fedora/20/x86_64/primary_db | 18 MB 00:04:35 (1/2): updates/20/x86_64/pkgtags | 1.0 MB 00:00:09 (2/2): updates/20/x86_64/updateinfo | 920 kB 00:00:18 Resolving Dependencies --> Running transaction check ---> Package net-tools.x86_64 0:2.0-0.15.20131119git.fc20 will be installed --> Finished Dependency Resolution Dependencies Resolved ==================================================================================================== Package Arch Version Repository Size ==================================================================================================== Installing: net-tools x86_64 2.0-0.15.20131119git.fc20 fedora 308 k Transaction Summary ==================================================================================================== Install 1 Package Total download size: 308 k Installed size: 937 k Downloading packages: warning: /var/cache/yum/x86_64/20/fedora/packages/net-tools-2.0-0.15.20131119git.fc20.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID 246110c1: NOKEY Public key for net-tools-2.0-0.15.20131119git.fc20.x86_64.rpm is not installed net-tools-2.0-0.15.20131119git.fc20.x86_64.rpm | 308 kB 00:00:10 Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-20-x86_64 Importing GPG key 0x246110C1: Userid : "Fedora (20)" Fingerprint: c7c9 a9c8 9153 f201 83ce 7cba 2eb1 61fa 2461 10c1 Package : fedora-release-20-1.noarch (@anaconda) From : /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-20-x86_64 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : net-tools-2.0-0.15.20131119git.fc20.x86_64 1/1 Verifying : net-tools-2.0-0.15.20131119git.fc20.x86_64 1/1 Installed: net-tools.x86_64 0:2.0-0.15.20131119git.fc20 Complete!
2. How to set the hostname :
[root@localhost ~]# vi /etc/hostname
Update to the preferred hostname :
fedora20.ehowstuff.local
3. Verify the interface name. In my case, the auto assigned interface for my ip address was ifcfg-ens32. It could be different from your server :
[root@localhost ~]# ls /etc/sysconfig/network-scripts/ ifcfg-ens32 ifdown-isdn ifup-aliases ifup-plip ifup-wireless ifcfg-lo ifdown-post ifup-bnep ifup-plusb init.ipv6-global ifdown ifdown-ppp ifup-eth ifup-post network-functions ifdown-bnep ifdown-routes ifup-ippp ifup-ppp network-functions-ipv6 ifdown-eth ifdown-sit ifup-ipv6 ifup-routes ifdown-ippp ifdown-tunnel ifup-ipx ifup-sit ifdown-ipv6 ifup ifup-isdn ifup-tunnel
4. Configure static IP address :
[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens32
The original configuration file :
TYPE="Ethernet" BOOTPROTO="dhcp" DEFROUTE="yes" IPV4_FAILURE_FATAL="no" IPV6INIT="yes" IPV6_AUTOCONF="yes" IPV6_DEFROUTE="yes" IPV6_PEERDNS="yes" IPV6_PEERROUTES="yes" IPV6_FAILURE_FATAL="no" NAME="ens32" UUID="8f3bcce9-631f-4874-a642-c78b2badb94d" ONBOOT="yes" HWADDR="00:0C:29:8C:7B:FE" PEERDNS="yes" PEERROUTES="yes"
Change to below :
TYPE="Ethernet" BOOTPROTO="none" DEFROUTE="yes" IPV4_FAILURE_FATAL="no" IPV6INIT="yes" IPV6_AUTOCONF="yes" IPV6_DEFROUTE="yes" IPV6_PEERDNS="yes" IPV6_PEERROUTES="yes" IPV6_FAILURE_FATAL="no" NAME="ens32" UUID="8f3bcce9-631f-4874-a642-c78b2badb94d" ONBOOT="yes" HWADDR="00:0C:29:8C:7B:FE" PEERDNS="yes" PEERROUTES="yes" IPADDR="192.168.0.20" NETMASK="255.255.0.0" GATEWAY="192.168.0.1"
5. Disable network manager and use the simple network service :
[root@localhost ~]# systemctl disable NetworkManager.service rm '/etc/systemd/system/dbus-org.freedesktop.NetworkManager.service' rm '/etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service' rm '/etc/systemd/system/multi-user.target.wants/NetworkManager.service'
[root@localhost ~]# systemctl start network.service [root@localhost ~]# chkconfig network on
6. Reboot server :
[root@localhost ~]# reboot
7. Once rebooted, verify the updated hostname and ip address :
[root@fedora20 ~]# hostname fedora20.ehowstuff.local [root@fedora20 ~]# ifconfig ens32: flags=4163mtu 1500 inet 192.168.0.20 netmask 255.255.0.0 broadcast 192.168.255.255 inet6 fe80::20c:29ff:fe8c:7bfe prefixlen 64 scopeid 0x20 ether 00:0c:29:8c:7b:fe txqueuelen 1000 (Ethernet) RX packets 335 bytes 34848 (34.0 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 322 bytes 28792 (28.1 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73 mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 0 (Local Loopback) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
