Linux之IPV4的配置

通過 nmcli? connection? show 命令可以查看識別的網(wǎng)卡名稱。

nmcli?connection?show 名稱????UUID??????????????????????????????????類型????????????設備??? ens33???f45a714b-7ccc-4e58-9f52-e8a6c3027a15??802-3-ethernet??ens33?? virbr0??32b28b6a-4b00-4e7c-9a41-2217b2c25449??bridge??????????virbr0

虛擬機的網(wǎng)卡配置文件在/etc/sysconfig/network-scripts/ 路徑下。vincen這里舉例配置ens33網(wǎng)卡的ipv4的方法

cd?/etc/sysconfig/network-scripts/?? #切換到網(wǎng)卡配置文件的路徑 ? ls?????#查看當前路徑下的所有文件 ifcfg-ens33??ifdown-isdn??????ifup??????????ifup-plip??????ifup-tunnel ifcfg-lo?????ifdown-post??????ifup-aliases??ifup-plusb?????ifup-wireless ifdown???????ifdown-ppp???????ifup-bnep?????ifup-post??????init.ipv6-global ifdown-bnep??ifdown-routes????ifup-eth??????ifup-ppp???????network-functions ifdown-eth???ifdown-sit???????ifup-ib???????ifup-routes????network-functions-ipv6 ifdown-ib????ifdown-Team??????ifup-ippp?????ifup-sit ifdown-ippp??ifdown-TeamPort??ifup-ipv6?????ifup-Team ifdown-ipv6??ifdown-tunnel????ifup-isdn?????ifup-TeamPort

修改ifcfg-ens33的配置文件

vim?ifcfg-ens33????????????#修改網(wǎng)卡ens33的配置 ?TYPE=Ethernet?????????????#網(wǎng)絡類型為Ethernet ?PROXY_METHOD=none??? ?BROWSER_ONLY=no ?BOOTPROTO=static????????????????????????#默認是dhcp，這里修改為static?靜態(tài)分配 ?DEFROUTE=yes ?IPV4_FAILURE_FATAL=no ?IPV6INIT=yes??????????????#啟動ipv6 ?IPV6_AUTOCONF=yes?????????#啟動自動配置ipv6 ?IPV6_DEFROUTE=yes?????????#啟動ipv6默認值 ?IPV6_FAILURE_FATAL=no ?IPV6_ADDR_GEN_MODE=stable-privacy ?NAME=ens33?????????????????????????#名為ens33 ?UUID=f45a714b-7ccc-4e58-9f52-e8a6c3027a15????#唯一識別碼 ?DEVICE=ens33???????????????????????#網(wǎng)卡設備名為ens33 ?ONBOOT=yes??????????????????????????????#默認是no，這里修改為yes?允許啟動此網(wǎng)卡 ?IPADDR=172.25.0.1???????????????????????#增加項，增加的ip為172.25.0.1 ?PREFIX=16???????????????????????????????#增加項，增加的子網(wǎng)掩碼為16 ?GETAWAY=172.25.0.3??????????????????????#增加項，增加的網(wǎng)關為172.25.0.3（此網(wǎng)關是根據(jù)Windows上的網(wǎng)絡共享中心里的VNnet1的IP地址的）

配置完成后重啟網(wǎng)卡

service?network?restart???#重啟網(wǎng)卡 ? ###或者### ? systemctl?restart?network.service??#重啟網(wǎng)絡服務

重啟網(wǎng)卡成功后，通過ifconfig 命令可以查看網(wǎng)卡名稱以及具體信息，比如網(wǎng)卡相對應的IP、子網(wǎng)掩碼、網(wǎng)關等等。vincen的虛擬機里第一張網(wǎng)卡名（最左邊）是ens33，IP（inet）是172.25.0.5，子網(wǎng)掩碼（netmask）255.255.0.0

ifconfig?????#查看網(wǎng)絡的詳細信息 ? ens33:?flags=4163??mtu?1500 ????????inet?172.25.0.1??netmask?255.255.0.0??broadcast?172.25.255.255 ????????inet6?fe80::9bfb:e5a9:5911:2ed0??prefixlen?64??scopeid?0x20 ????????ether?00:0c:29:ad:05:c6??txqueuelen?1000??(Ethernet) ????????RX?packets?90??bytes?9051?(8.8?KiB) ????????RX?errors?0??dropped?0??overruns?0??frame?0 ????????TX?packets?88??bytes?12178?(11.8?KiB) ????????TX?errors?0??dropped?0?overruns?0??carrier?0??collisions?0 ? lo:?flags=73??mtu?65536 ????????inet?127.0.0.1??netmask?255.0.0.0 ????????inet6?::1??prefixlen?128??scopeid?0x10 ????????loop??txqueuelen?1??(Local?Loopback) ????????RX?packets?66??bytes?5676?(5.5?KiB) ????????RX?errors?0??dropped?0??overruns?0??frame?0 ????????TX?packets?66??bytes?5676?(5.5?KiB) ????????TX?errors?0??dropped?0?overruns?0??carrier?0??collisions?0 ? virbr0:?flags=4099??mtu?1500 ????????inet?192.168.122.1??netmask?255.255.255.0??broadcast?192.168.122.255 ????????ether?52:54:00:46:ba:48??txqueuelen?1000??(Ethernet) ????????RX?packets?0??bytes?0?(0.0?B) ????????RX?errors?0??dropped?0??overruns?0??frame?0 ????????TX?packets?0??bytes?0?(0.0?B) ????????TX?errors?0??dropped?0?overruns?0??carrier?0??collisions?0

此時，linux的IP就已經(jīng)配置成功了
