How to setup static IP on AlmaLinux 8

To set up static IP configuration on your VPS, you have to login into Fleio.
After connecting to Fleio you can use the console to run commands

Login to SSH or console.
Make sure you are sudo
Edit file /etc/cloud/cloud.cfg.d/90-almalinux-networking.cfg and put in the following line.
```
network: {config:disabled}
```

Replace the content of /etc/sysconfig/network-scripts/ifcfg-eth0 with the following lines:

BOOTPROTO=none  
DEVICE=eth0  
ONBOOT=yes  
TYPE=Ethernet  
IPADDR=<your IPv4 address>  
PREFIX=<your IPv4 address prefix> 
GATEWAY=<your IPv4 gateway>  
IPV6ADDR=<your IPv6 address>/64  
IPV6_DEFAULTGW=<your IPv6 gateway>

In order to get the Prefix, you can use ip a and will receive an output like the following, where the prefix is 24:

 inet 185.125.109.114/24 brd 185.125.109.255 scope global noprefixroute eth0
       valid_lft forever preferred_lft forever

In order to get the Gateway, you can use ip r and will receive an output like the following, where the gateway is 185.125.109.1:

default via 185.125.109.1 dev eth0 proto static metric 100
185.125.109.0/24 dev eth0 proto kernel scope link src 185.125.109.114 metric 100

Restart network using the commands or reboot

systemctl disable dhclient6.service  
ifdown eth0  
ifup eth0

You can also run

systemctl restart NetworkManager

To verify your network configuration, use the following command:
```
ip a
```

Configuration for more IPs in your instance.

If you want to configure multiple IPs in your instance, we need to create another cfg file.
In default configuration we have ifcfg-eth0 and we have to create file with a different name like ifcfg-eth0:1 using the following command:

vim /etc/sysconfig/network-scripts/ifcfg-eth0:1

Note We can choose eth0:1, eth0:2, eth0:3, and so on, depending on how many IPs we want to configure.

BOOTPROTO=none  
DEFROUTE=yes  
DEVICE=eth0:1  
GATEWAY=<your IPv4 gateway>  
IPADDR=<your IPv4 address>  
PREFIX=<Your IPv4 prefix>  
IPV6ADDR=<your IPv6 address/64>  
IPV6INIT=yes  
IPV6_DEFAULTGW=<your IPv6 gateway>  
ONBOOT=yes  
STARTMODE=auto  
TYPE=Ethernet  
USERCTL=no

In order to get the Prefix, you can use ip a and will receive an output like the following, where the prefix is 24:

 inet 185.125.109.114/24 brd 185.125.109.255 scope global noprefixroute eth0
       valid_lft forever preferred_lft forever

In order to get the Gateway, you can use ip r and will receive an output like the following, where the gateway is 185.125.109.1:

default via 185.125.109.1 dev eth0 proto static metric 100
185.125.109.0/24 dev eth0 proto kernel scope link src 185.125.109.114 metric 100

After the configuration is done, you have to restart network:

ifdown [file configuration]   (ifdown eth0:1)  
ifup   [file configuration]   (ifup eth0:1)

You can also run

systemctl restart NetworkManager

To verify your network configuration, use the following command:

ip a
