Linux雙網(wǎng)卡綁定腳本的方法示例
更新時(shí)間：2018年11月27日 09:26:19 作者：zaa47
linux運(yùn)維及配置工作中，常常會(huì)用到雙網(wǎng)卡綁定，這篇文章主要介紹了Linux雙網(wǎng)卡綁定腳本的方法示例，小編覺(jué)得挺不錯(cuò)的，現(xiàn)在分享給大家，也給大家做個(gè)參考。一起跟隨小編過(guò)來(lái)看看吧
linux運(yùn)維及配置工作中，常常會(huì)用到雙網(wǎng)卡綁定，少數(shù)幾臺(tái)服務(wù)器的配置還好，如果是需要配置幾十甚至上百臺(tái)，難免會(huì)枯燥乏味，易于出錯(cuò)，我編寫了這個(gè)雙網(wǎng)卡綁定的輔助腳本，可傻瓜式地完成linux雙網(wǎng)卡綁定工作，當(dāng)然，該腳本主要還是用于小批量的系統(tǒng)配置，如需配置大量的服務(wù)器，可提取腳本中的bonding函數(shù)，稍作修改即可，你值得一試！
1.適用范圍
該shell腳本可在以下linux系統(tǒng)創(chuàng)建多個(gè)綁定網(wǎng)卡，用于生產(chǎn)環(huán)境沒(méi)問(wèn)題的：
- Redhat 5.x
- CentOS 5.x
- Kylin 3.x
- KUX 2.x
2.腳本特點(diǎn)
---------------------------------------------- ------ Network Configuration Assistant ------ ---------------------------------------------- The information you have entered: First NIC :eth0 Second NIC :eth1 bond name :bond1 IP address :192.168.56.11 netmask :255.255.255.0 bonding_mode :mode=1 primary NIC :none ---------------------------------------------- Pls make sure its OK[y/n]:y
如上，腳本在使用過(guò)程中，會(huì)依次提示輸入需要綁定的子網(wǎng)卡名稱、綁定網(wǎng)卡名稱、IP地址和子網(wǎng)掩碼、綁定模式、是否指定主網(wǎng)卡，并主動(dòng)對(duì)系統(tǒng)中可用網(wǎng)卡進(jìn)行識(shí)別并列出，供用戶選擇，同時(shí)會(huì)判斷輸入的各項(xiàng)信息的正確性，保障雙網(wǎng)卡綁定順利進(jìn)行。
3.使用說(shuō)明
首先將腳本上傳至linux系統(tǒng)任意目錄下，使用root用戶執(zhí)行：
[root@node1 tmp]# sh bonding_v2.0.sh ---------------------------------------------- ------ Network Configuration Assistant ------ ---------------------------------------------- 4 network cards available: eth0 eth1 eth2 eth3 ---------------------------------------------- Please enter the First NIC:_
首先腳本會(huì)列出系統(tǒng)中有多少可用網(wǎng)卡，并提示輸入需要綁定的第一塊子網(wǎng)卡的名稱，這里輸入eth2。
無(wú)需擔(dān)心輸入錯(cuò)誤，輸入重復(fù)等問(wèn)題，腳本會(huì)自動(dòng)判斷你的輸入信息是否正確。
---------------------------------------------- ------ Network Configuration Assistant ------ ---------------------------------------------- 4 network cards available: eth0 eth1 eth2 eth3 The information you have entered: First NIC : eth2 ---------------------------------------------- Please select the second NIC:_
接著輸入需要綁定的第二塊網(wǎng)卡的名稱eth3，如果輸入錯(cuò)誤會(huì)出現(xiàn)相應(yīng)的提示，比如錯(cuò)輸入為eth8，會(huì)提示需要重新輸入：
---------------------------------------------- ------ Network Configuration Assistant ------ ---------------------------------------------- 4 network cards available: eth0 eth1 eth2 eth3 The information you have entered: First NIC : eth2 ---------------------------------------------- eth8 is not available,Please enter another one. Please select the second NIC:_
正確輸入需要綁定的第二塊網(wǎng)卡eth3后，如果linux系統(tǒng)中之前不存在綁定網(wǎng)卡，則默認(rèn)第一個(gè)綁定網(wǎng)卡的名稱為bond0，如果系統(tǒng)中存在綁定網(wǎng)卡，腳本會(huì)提示輸入bondN(N為數(shù)字)：
---------------------------------------------- ------ Network Configuration Assistant ------ ---------------------------------------------- The information you have entered: First NIC : eth2 Second NIC : eth3 bond name : bond0 ---------------------------------------------- The default first bond name is -- bond0. Please enter an IP address:_
按照提示輸入需要綁定的IP地址，比如10.1.1.1
腳本會(huì)自動(dòng)判斷輸入的IP地址格式和范圍是否正確，無(wú)需擔(dān)心輸入錯(cuò)誤
---------------------------------------------- ------ Network Configuration Assistant ------ ---------------------------------------------- The information you have entered: First NIC : eth2 Second NIC : eth3 bond name : bond0 IP address : 10.1.1.1 ---------------------------------------------- Pls enter the NETMASK[255.255.255.0]:_
輸入IP地址后，會(huì)提示輸入子網(wǎng)掩碼，默認(rèn)為255.255.255.0，直接回車即可，也可以輸入自定義的子網(wǎng)掩碼。
---------------------------------------------- ------ Network Configuration Assistant ------ ---------------------------------------------- The information you have entered: First NIC : eth2 Second NIC : eth3 bond name : bond0 IP address : 10.1.1.1 netmask : 255.255.255.0 ---------------------------------------------- Pls enter the bonding_mode[default:mode=1,active-backup]:_
這一步是輸入網(wǎng)卡綁定級(jí)別，默認(rèn)使用主備模式：mode=1，直接回車即可，也可以輸入自定義的綁定級(jí)別（如輸入 mode=6），格式為：
mode=｛0,1,2,3,4,5,6｝ ---------------------------------------------- ------ Network Configuration Assistant ------ ---------------------------------------------- The information you have entered: First NIC :eth2 Second NIC :eth3 bond name :bond0 IP address :10.1.1.1 netmask :255.255.255.0 bonding_mode :mode=1 ---------------------------------------------- 1-eth2 2-eth3 3-none choose whether to set up the primary NIC or not[default:3-none]:_
此時(shí)腳本提示是否設(shè)置primary網(wǎng)卡，primary網(wǎng)卡的作用是在子網(wǎng)卡均正常時(shí)，primary網(wǎng)卡優(yōu)先處于活動(dòng)狀態(tài)，這里默認(rèn)為不設(shè)置primary網(wǎng)卡，也可以輸入數(shù)字1或2選擇一個(gè)網(wǎng)卡為primary網(wǎng)卡。
---------------------------------------------- ------ Network Configuration Assistant ------ ---------------------------------------------- The information you have entered: First NIC :eth2 Second NIC :eth3 bond name :bond0 IP address :10.1.1.1 netmask :255.255.255.0 bonding_mode :mode=1 primary NIC :none ---------------------------------------------- Pls make sure its OK[y/n]:_
至此，所有信息輸入完畢，腳本會(huì)讓您判斷輸入的所有信息是否正確，正確則輸入y，進(jìn)行下一步操作，否則輸入n，重新輸入以上信息。
---------------------------------------------- ------ Network Configuration Assistant ------ ---------------------------------------------- Complete! File backup directory: /etc/sysconfig/network-scripts/inspur_bak you can check the file and then restart the network service. 1 ) service network restart 2 ) exit ---------------------------------------------- Please make your choice:_
看到這里時(shí)，所有綁定網(wǎng)卡的配置文件已經(jīng)修改完畢了，輸入1重啟網(wǎng)絡(luò)服務(wù)；輸入2直接退出腳本。
建議選擇重啟網(wǎng)絡(luò)服務(wù)，如果直接退出腳本而不重啟網(wǎng)絡(luò)服務(wù)，修改的配置文件是不會(huì)生效的，并且在使用該腳本創(chuàng)建下一個(gè)綁定網(wǎng)卡時(shí)顯示信息會(huì)出現(xiàn)異常(因?yàn)槟_本通過(guò)ifconfig命令獲取當(dāng)前網(wǎng)卡信息)。
you can check the file and then restart the network service.
1 ) service network restart
2 ) exit
----------------------------------------------
Please make your choice:1

第一次重啟網(wǎng)絡(luò)服務(wù)時(shí)可能會(huì)出現(xiàn)以上類似報(bào)錯(cuò)，無(wú)需擔(dān)心，其實(shí)配置已經(jīng)完成，再次重啟網(wǎng)絡(luò)服務(wù)即恢復(fù)正常。
