linux系统配置网络有多种方式，本篇文章重点为大家讲解一下redhat中配置网络的多种方法，有需要的小伙伴可以参考一下。
图形界面配置方法
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！
通过修改配置文件
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
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=dhcp
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=no

"/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
利用工具配置
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
