CentOS设置ip「快速设置」

人得有信念

1：检察网卡的DNS的设置文件:
注：不必要修改.
[root@localhost ~]# cat /etc/resolv.conf # Generated by NetworkManagersearch lannameserver fd7b:ac2f:6d73::1注：在重启网络服务[service network restart]后,
体系会主动利用[/etc/sysconfig/network-scripts/ifcfg-enp0s3]中eg:DNS1=8.8.8.8,
主动设置[/etc/resolv.conf]中nameserver的设置为eg:nameserver 8.8.8.8,
此为主动设置乐成,手动设置,重启网络服务将被覆盖或清空！
设置参数：
8.8.8.8 #google域名服务器 8.8.4.4 #google域名服务器 192.168.10.1 #网卡对应的网关的IP地点(默认网关)255.255.255.0 #网卡对应的网络掩码(子网掩码)192.168.10.56 #网卡对应的ip地点2：修改网卡的网关的设置文件:
[root@localhost sysconfig]# pwd/etc/sysconfig[root@localhost sysconfig]# vim network[root@localhost sysconfig]# cat network# Created by anacondaNETWORKING=yes HOSTNAME=CentOS-Slave1NETWORKING_IPV6=no PEERNTP=noGATEWAY=192.168.10.1 注：设置本机的主机名,这里设置的主机名要/etc/sysconfig/network和/etc/hosts中设置的主机名对应同等(可选)
3：修改网卡的IP地点的设置文件：
[root@CentOS-Slave1 network-scripts]# pwd/etc/sysconfig/network-scripts[root@CentOS-Slave1 network-scripts]# vim ifcfg-enp0s3 [root@CentOS-Slave1 network-scripts]# cat ifcfg-enp0s3 DEVICE=enp0s3ONBOOT=yesBOOTPROTO=staticIPADDR=192.168.10.56NETMASK=255.255.255.0DNS1=8.8.8.8 DNS2=8.8.4.4 centos7具体设置见,备注附件！
4：修改主机名设置文件：
注：手动添加ip和主机名,第三行.
[root@localhost etc]# pwd/etc[root@localhost etc]# vim hosts[root@localhost etc]# cat hosts127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4::1 localhost localhost.localdomain localhost6 localhost6.localdomain6192.168.10.56 CentOS-Slave15：重启网络服务：
[root@localhost init.d]# service network restartRestarting network (via systemctl): [ OK ]6：再次检察网卡的DNS的设置文件：
[root@localhost init.d]# cat /etc/resolv.conf # Generated by NetworkManagersearch lan lan.nameserver 8.8.8.8nameserver 8.8.4.4nameserver fd7b:ac2f:6d73::1注：DNS已经设置完毕！
7：检察主机名称[重启见效]：
[root@localhost init.d]# hostnameCentOS-Slave1检察ip：
[root@CentOS-Slave1 /]# ifconfigenp0s3: flags=4163 mtu 1500 inet 192.168.10.56 netmask 255.255.255.0 broadcast 192.168.10.255 inet6 fe80::a00:27ff:fe87:b3c0 prefixlen 64 scopeid 0x20 ether 08:00:27:87:b3:c0 txqueuelen 1000 (Ethernet) RX packets 44075 bytes 47664947 (45.4 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 9704 bytes 1365665 (1.3 MiB) 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 0 (Local Loopback) RX packets 3 bytes 303 (303.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 3 bytes 303 (303.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0具体解说ip设置检察：CentOS的ip设置/Ubuntu的ip设置:在Oracle VM VirtualBOX下CentOS 7/Ubuntu 体系设置网络：接入internet（上网）和 局域网 ip
