To check your system’s host name and network configuration: - Log on to the system as the root user. - Type vi /etc/hosts to open the host file and modify the contents. - Verify that the file is in the following format: - Verify that the loopback entry (127.0.0.1) appears in the file. A correctly configured file should look like this: Note : The IP addresses used here are for illustration purposes only; they are not valid values. # Do not remove the following line, or various programs# that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost 10.0.1.100 server1.example.com server1 ::1 localhost6.localdomain6 localhost6 - Type :wq to close the file. - Type vi /etc/sysconfig/network to open the network sysconfig file and modify the contents. - Verify the host name. A correctly configured file should look like this: Note : The IP addresses used here are for illustration purposes only; they are not valid values. NETWORKING=yesHOSTNAME=myserver.mydomain.com GATEWAY=10.100.0.1 – Modify the file as needed. - Type :wq to close the file. - Type vi /etc/sysconfig/network-scripts/ifcfg-eth0 to open the network scripts file and modify the contents. - Verify that network information.

DEVICE=eth0BOOTPROTO=static BROADCAST=10.1.1.1 IPADDR=10.1.1.1 NETMASK=255.255.0.0 NETWORK=10.1.0.0 ONBOOT=yes – Modify the file as needed. Some finishing touches. Type the following [root@localhost]#yum install irqbalance[root@localhost]#yum install readahead[root@localhost]#yum install nano[root@localhost]#yum update Also run [root@localhost]#system-config-securitylevel Set both Security Level and SELinux to Disabled and hit OK:Note: This isn't working for me right now so I am missing a pre-req (will figure it out)Make these changes active, restart the system by typing: shutdown -r now If you happen to be running CentOS in a VMware session, now is the time to install vmware-toolsClick Install VMware Tools [root@localhost]#mount /dev/hdc /media[root@localhost]#ls /media[root@localhost]#tar -C /tmp -zxvf /media/VMwareTools-7.9.6-173382.tar.gz[root@localhost]#umount /media[root@localhost]#yum install perl[root@localhost]#yum -y install libX11-devel libXtst[root@localhost]#yum -y install gcc[root@localhost]#yum -y install kernel-headers kernel-devel[root@localhost]#/tmp/vmware-tools-distrib/vmware-install.pl[root@localhost]#/usr/bin/vmware-toolbox[root@localhost]#shutdown -r now Quote Link to comment Share on other sites More sharing options...
