You can create virtual IP address with linux service. I designed the linux service to create a virtual IP address when operating system is rebooted.
My System Properties
Ethernet Adaptor Name : ens14025
Virtual IP : 192.168.44.55
1. Create Bash Script To Create Virtual IP Address
[root@test ~]# vi /opt/scripts/virtual_ip_up.sh #!/bin/bash ifconfig ens14025:1 192.168.44.55 netmask 255.255.255.0 [root@test ~]# chmod 744 /opt/scripts/virtual_ip_up.sh
2. Create Service File
[root@test ~]# vi /etc/systemd/system/virtual_ip.service [Unit] Description=Virtual IP After=syslog.target After=network.target [Service] Type=simple User=root Group=root OOMScoreAdjust=-1000 ExecStart=/opt/scripts/virtual_ip_up.sh TimeoutSec=300 [Install] WantedBy=multi-user.target [root@test ~]# chmod 644 /etc/systemd/system/virtual_ip.service
3. Start Service
[root@test ~]# systemctl daemon-reload [root@test ~]# systemctl start virtual_ip.service [root@test ~]# systemctl enable virtual_ip.service
