Then, you can use the following command to activate the ethX. # ifconfig ethX up ,where X=0,1,2,... 這里也可以通過(guò)系統(tǒng)→管理→網(wǎng)絡(luò)來(lái)設(shè)置IP地址等，最后激活。 1. Set manually a. Set the IP address of your machine. # ifconfig ethX "the IP address of your machine" b. Set the IP address of DNS. Insert the following configuration in /etc/resolv.conf. nameserver "the IP address of DNS" c. Set the IP address of gateway. # route add default gw "the IP address of gateway" 2. Set by doing configurations in /etc/sysconfig/network-scripts /ifcfg-ethX for Redhat and Fedora, or /etc/sysconfig/network /ifcfg-ethX for SuSE. There are two examples to set network configurations. a. Fix IP address: DEVICE=eth0 BOOTPROTO=static ONBOOT=yes TYPE=ethernet NETMASK=255.255.255.0 IPADDR=192.168.1.1 GATEWAY=192.168.1.254 BROADCAST=192.168.1.255 2. 修改：＃vi /etc/hosts，在該文本中，增加兩行： 127.0.0.1 localhost.localdomain localhost 192.168.4.101 node3（根據(jù)機(jī)器本身情況設(shè)置） 修改：vi /etc/hosts.equiv，增加一行：(如果沒(méi)有該文本，可建立一個(gè)) node3 3. 啟動(dòng)ssh服務(wù) 大部分的Linux版本應(yīng)該都會(huì)自帶該程序 ＃ssh-keygen ＃cd .ssh ＃cp id_rsa.pub authorized_keys ＃ssh node3（如果成功，會(huì)顯示上次登陸的時(shí)間， node3是主機(jī)名） 附加信息： ifup eth0看看能否啟動(dòng)eth0 lsmod看看有沒(méi)有加載網(wǎng)卡驅(qū)動(dòng) dmesg看看有沒(méi)有網(wǎng)卡啟動(dòng)時(shí)的錯(cuò)誤信息 |
