本篇內(nèi)容主要講解“l(fā)inux的網(wǎng)絡(luò)參數(shù)怎么配置”，感興趣的朋友不妨來看看。本文介紹的方法操作簡單快捷，實(shí)用性強(qiáng)。下面就讓小編來帶大家學(xué)習(xí)“l(fā)inux的網(wǎng)絡(luò)參數(shù)怎么配置”吧!
主要用途：
1、查看網(wǎng)絡(luò)接口設(shè)置： ifconfig –a或ifconfig 網(wǎng)絡(luò)接口 –a
2、網(wǎng)絡(luò)配置 ifconfig 網(wǎng)絡(luò)接口 [add/del] ip地址 netmask 子網(wǎng)掩碼 例：ifocnfig eth0 10.2.3.4 [netmask 255.255.255.0]
3、網(wǎng)絡(luò)接口的激活/關(guān)閉 格式：ifconfig 網(wǎng)絡(luò)接口 up/down
配置dns
建立/etc/resolv.conf文件，在里面寫入dns服務(wù)器地址
配置主機(jī)名
配置/etc/sysconfig/network文件，同時(shí)使用hostname 修改主機(jī)名
使用例子：
復(fù)制代碼 代碼如下:
[root@twin0898 sysconfig]# cat network
network networking/ network-scripts/
[root@twin0898 sysconfig]# cat network
networking=yes
gateway=125.39.149.1
hostname=twin0898
networking_ipv6=no
通用格式：
1、到網(wǎng)絡(luò)的網(wǎng)關(guān) route add/delete -net 目標(biāo)網(wǎng)絡(luò) netmask 掩碼 gw 網(wǎng)關(guān)地址 [dev 網(wǎng)絡(luò)接口]
2、到單一主機(jī)的網(wǎng)關(guān) route add/delete -host 目標(biāo)主機(jī) gw 網(wǎng)關(guān)地址 [dev 網(wǎng)絡(luò)接口]
3、添加默認(rèn)網(wǎng)關(guān)： route add default gw 網(wǎng)關(guān)地址 檢查主機(jī)路由表：route，netstat -nr
// 總結(jié)如下：
1、網(wǎng)絡(luò)配置檢查：ifconfig -a
2、連通性檢查：ping、traceroute
3、路由表檢查：route或netstat –nr
4、dns客戶端運(yùn)行狀態(tài)檢查：nslookup
// 使用例子如下
// ifconfig -a
復(fù)制代碼 代碼如下:
root@cinematest2:/usr/local/jdk# ifconfig -a
