生成新的配置文件

[root@qdlinux ~]# nmcli connection add con-name ens33-dhcp ifname ens32 autoconnect yes type ethernet ipv4.method auto 
Connection 'ens33-dhcp' (ee3fc1d8-8d0e-4749-a624-cbdf6505bfe4) successfully added.

[root@qdlinux ~]# nmcli connection

查看配置文件

[root@qdlinux ~]# less /etc/sysconfig/network-scripts/ifcfg-ens33-dhcp

(END)

启动新的配置文件,如果此时是用ssh连接上去的会掉线.

[root@qdlinux ~]# nmcli connection up ens33-dhcp 

Socket error Event: 32 Error: 10053.
Connection closing...Socket close.

Connection closed by foreign host.

Disconnected from remote host(192.168.56.5) at 09:49:30.

在虚拟机中查看ip地址,发现ip地址已经自动获取,并且已经改变.

现在切换原来的配置文件,ssh再次连接又连接上去了.

[root@qdlinux ~]# nmcli connection up ens32

删除该设备配置文件,重新配置一个新的配置文件.

[root@qdlinux ~]# nmcli connection delete

手动方式修改配置文件

通过手动方式修改配置文件,首先复制一份原始配置命名为ifcfg-ens35-static,修改配置名称、协议、删除UUID、IP地址

[root@qdlinux network-scripts]# vim ifcfg-ens35-static 
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
TYPE=Ethernet
PROXY_METHOD=none
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static //修改为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=ens35-static//修改为ens35-static
DEVICE=ens35//修改为ens35
ONBOOT=yes
IPADDR=192.168.56.26
PREFIX=24
GATEWAY=192.168.56.2
DNS1=202.102.134.68
DNS2=114.114.114.114

重新加载一下配置文件启动配置

[root@qdlinux network-scripts]# nmcli connection reload

[root@qdlinux network-scripts]# nmcli connection down ens35-static ; nmcli connection up ens35-static

修改centos默认ens32为eth0方法

[root@qdlinux network-scripts]# vim /etc/sysconfig/grub
