### 设置ip 

#### 最新方式

##### 第一种

sudo apt remove resolvconf

sudo vim /etc/network/interfaces
```bash
# dhcp
auto eth0
iface eth0 inet dhcp
# static
auto eth0
iface eth0 inet static
address 192.10.11.121
netmask 255.255.255.0
gateway 192.10.11.1

```

sudo vim /etc/systemd/resolved.conf
DNS=223.5.5.5

cat /run/systemd/resolve/resolv.conf
sudo rm /etc/resolv.conf
sudo ln -s /run/systemd/resolve/resolv.conf /etc/

sudo service systemd-resolved restart
sudo systemd-resolve --status | grep 'DNS Servers'

sudo /etc/init.d/networking restart
sudo reboot


##### 第二种(无效)
sudo vim /etc/resolvconf/resolv.conf.d/head
nameserver 223.5.5.5
nameserver 114.114.114.114

cat /run/resolvconf/resolv.conf


#### static ip(无效)

`sudo vim /etc/network/interfaces`
```bash
auto eth0
iface eth0 inet static
address 192.10.11.121
netmask 255.255.255.0
gateway 192.10.11.1
```

`sudo vim /etc/resolvconf/resolv.conf.d/base`
```bash
nameserver 8.8.8.8
nameserver 114.114.114.114
nameserver 8.8.4.4
```

`sudo vim /etc/resolv.conf`
```bash
nameserver 127.0.0.53
options edns0
search lan
```
chattr +i /etc/resolv.conf


设置网卡的 DNS Server
sudo systemd-resolve --set-dns=114.114.114.114 --interface enp4s0

sudo systemd-resolve --status | grep 'DNS Servers'

重置网卡的 DNS 设置 请慎用
sudo systemd-resolve --revert --interface=enp4s0

刷新本地 DNS 缓存
sudo systemd-resolve --flush-caches

vim /etc/systemd/resolved.conf
DNS=223.5.5.5
sudo service systemd-resolved restart

#### auto ip(无效)

`sudo vim /etc/network/interfaces`
```bash
auto eth0
iface eth0 inet dhcp
```

`sudo resolvconf -u`
<!-- sudo /etc/init.d/networking restart -->
`sudo reboot`
<!-- sudo ip addr flush eth0 -->

#### 加载网卡



#### 更新时间


crontab -u root -e
* */2 * * * ntpdate time1.aliyun.com;hwclock --systohc
service cron restart

#### ip
