通常為了節省時間,在vmware中安裝一套linux後,會直接轉殖乙份出來使用。但在轉殖redhat 6後,會發現網絡卡名稱發生變化,比如eth0會變為eth1,下面介紹下轉殖後的redhat 6,如何修改主機名、ip位址和網絡卡名稱。
修改主機名(共2步)
hostname amto02
vi /etc/sysconfig/network -> 修改項:hostname=amto02
還原網絡卡名稱為eth0:
[root@amto02 u01]# cat /etc/udev/rules.d/70-persistent-net.rules.bak
# this file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
## you can modify it, as long as you keep each rule on a single
# line, and change only the value of the name= key.
# pci device 0x8086:0x100f (e1000) (custom name provided by external tool)
subsystem=="net", action=="add", drivers=="?*", attr=="00:0c:29:27:be:dc", attr=="1", kernel=="eth*", name="eth0"
# pci device 0x8086:0x100f (e1000)
subsystem=="net", action=="add", drivers=="?*", attr=="00:0c:29:8a:8d:19", attr=="1", kernel=="eth*", name="eth1"
在該配置檔案中會發現存在2條記錄,第二條記錄是轉殖/複製虛擬機器後,重新生成的乙個mac位址(00:0c:29:8a:8d:19),因此,需要把就配置刪除掉,也就是將第1條記錄刪除。並且第2條記錄的最後面,將eth1改為eth0。修改後的配置檔案為:
[root@amto02 u01]# cat /etc/udev/rules.d/70-persistent-net.rules
# this file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
## you can modify it, as long as you keep each rule on a single
# line, and change only the value of the name= key.
# pci device 0x8086:0x100f (e1000)
subsystem=="net", action=="add", drivers=="?*", attr=="00:0c:29:8a:8d:19", attr=="1", kernel=="eth*", name="eth0"
執行setup或者system-config-network,按照提示填寫新的ip資訊即可。
重啟網絡卡服務:
service networkmanager restart
service network restart
vmware轉殖主機
因為準備搭建伺服器集群,但是乙個個虛擬機器的建立過於繁瑣,因此使用轉殖來減少工作量。開啟vmware,進入主介面,點選虛擬機器選項 點選轉殖 轉殖完成。解決方法 登陸進入剛轉殖的主機 輸入賬號密碼,我安裝的是最小化的centos 輸入命令 vim etc udev rules.d 70 persis...
