Fedora系统配置命令

一、配置网卡

vi /etc/sysconfig/network-scripts/ifcfg-enp0s3
HWADDR=08:00:27:6D:C8:A5
BOOTPROTO=static
TYPE=Ethernet
IPV4_FAILURE_FATAL=no
NAME=enp0s3
UUID=e578cc1d-85f3-34d9-ac9e-7e7528b6e100
ONBOOT=yes
IPADDR=10.0.100.36
NETMASK=255.255.255.0
GATEWAY=10.0.100.1
DNS=10.0.100.10

#ip addr

HWADDR=00:25:B3:22:41:B8
TYPE=Ethernet
NAME=enp2s0f0
UUID=34fbd164-ed38-35df-91eb-646f1cae9fd5
ONBOOT=yes
IPADDR=10.0.77.230
NETMASK=255.255.255.0
GATEWAY=10.0.77.254
DNS=10.0.100.10

重启网卡，才能生效：

ifdown enp2s0f0 && ifup enp2s0f0

 

#配置DNS

[root@teamplate ~]# vi /etc/resolv.conf
nameserver 10.0.100.10

#重启网卡命令

systemctl restart network.service

service network restart

ifdown enp0s3 and ifup enp0s3

#解决网卡开机获取不到IP地址

[root@git-node1 ~]# ifconfig enp0s3
enp0s3: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.0.100.36  netmask 255.255.255.0  broadcast 10.0.100.255
        inet6 fe80::a00:27ff:fe6d:c8a5  prefixlen 64  scopeid 0x20<link>
        ether 08:00:27:6d:c8:a5  txqueuelen 1000  (Ethernet)

[root@git-node1 ~]# ifconfig enp0s3 up
[root@git-node1 ~]# chkconfig --level 2345 network on
[root@git-node1 ~]# chkconfig --list 3:on

　　netconsole 0:off 1:off 2:off 3:off 4:off 5:off 6:off
　　network 0:off 1:off 2:on 3:on 4:on 5:on 6:off

 

[root@git network-scripts]# nmcli dev show enp2s0f0
GENERAL.设备: enp2s0f0
GENERAL.类型: ethernet
GENERAL.硬盘: 00:25:B3:22:41:B8

IP6.地址[1]: fe80::225:b3ff:fe22:41b8/64

二、关闭防火墙

systemctl stop firewalld.service #停止firewall
systemctl disable firewalld.service #禁止firewall开机启动

三、关闭selinux

# vi /etc/selinux/config
SELINUX=disabled

1、临时关闭（不用重启机器）：
setenforce 0  

四、yum源默认不配置

五、修改主机名

[root@git-nodel ~]# hostname
git-nodel

[root@git-nodel ~]# vi  /etc/hostname
git-nodel

#保存xshell，再登录，就可以看到更改后的新用户名
