[Linux]Vmware Oracle Linux6.5 避免網路卡DHCP設定每次重啟時自動修改/etc/resolv.conf

vmware安裝Oracle Linux 6.5，使用DHCP，每次重啟時會自動修改/etc/resolv.conf檔案中的nameserver項。


觀察到設定nameserver項會導致該伺服器上安裝的oacle lsnrctl和tnsping等響應緩慢，同時ssh也變得很慢，必須將nameservers項註釋掉。但每次重啟伺服器該檔案都會被修改，nameserver被重新設定。


避免這種情況的方法之一：


Modify your interface configuration file such as /etc/sysconfig/network-scripts/ifcfg-eth0 file and append any one of the following option:


# do not overwrite /etc/resolv.conf ##
PEERDNS=no
OR


## use the following nameservers in /etc/resolv.conf ##
PEERDNS=no
DNS1=8.8.8.8
DNS2=1.2.3.4
Save and close the file. Where,


PEERDNS=yes|no - Modify /etc/resolv.conf if peer uses msdns extension (PPP only) or DNS{1,2} are set, or if using dhclient. default to "yes".
DNS{1,2}= - Provide DNS addresses that are dropped into the resolv.conf file if PEERDNS is not set to "no".


問題解決，進圖形化介面看了一下，實際上就是把網路卡設定改為了DHCP address only
