RHEL7多种方式配置ip地址

点击桌面右上角有线连接处,选中配置ens33

在此输入ip地址，掩码，DNS，网关等

然后选中启动就ok了

如此网络配置就完成了！

通过修改ifcfg-ens33配置文件来修改配置ip

[root@localhost ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens33

BROWSER_ONLY=no
BOOTPROTO=dhcp
DEFROUTE=yes

IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy

"/etc/sysconfig/network-scripts/ifcfg-ens33" 15L, 279C  

将BOOTPROTO改为static
ONBOOT=no改为ONBOOT=yes
添加IPADDR NETMASK GATEWAY DNS1字段 如下所示：

[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens33 
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=96a5f670-6b15-4711-af6e-92aa92e1c66b
DEVICE=ens33
ONBOOT=yes

IPADDR=172.16.1.115
NETMASK=255.255.255.0
GATEWAY=172.16.1.254
DNS1=8.8.8.8

如此重启网卡就可以了！
[root@localhost ~]# systemctl restart network

输入以下命令，指定ip 掩码

[root@localhost ~]# nmcli connection modify ens33 ipv4.method manual ipv4.address 172.16.1.120/24 connection.autoconnect yes

重启网卡

[root@localhost ~]# ifconfig
