This guide will show you how to install the Unifi Controller on the CentOS server to allow you to set a central portal for managing either single or multiple sites of unifi devices.
Let’s Get Started.
1. Install CentOS
ISO can be obtained from the internet for free and works on Hyper V or ESX (any potentially others)
2. Update CentOS
Updating CentOS is a simple command using Yum. You just want to make sure that CentOS is up to date before its gets off the ground running.
root@techshare.vn [~]# yu update -y
3. Install prerequisites
root@techshare.vn [~]#yum -y install epel-release root@techshare.vn [~]# yum -y install mongodb-server java-1.8.0-openjdk unzip wget root@techshare.vn [~]#systemctl start mongod root@techshare.vn [~]#systemctl enable mongod root@techshare.vn [~]#sed -i /etc/selinux/config -r -e 's/^SELINUX=.*/SELINUX=disabled/g' root@techshare.vn [~]#systemctl reboot
4. Download and Extract the Unifi Controller (latest version can be found on unifi website)
root@techshare.vn [~]#useradd -r ubnt root@techshare.vn [~]#cd ~ && wget http://dl.ubnt.com/unifi/5.6.30/UniFi.unix.zip root@techshare.vn [~]#unzip -q UniFi.unix.zip -d /opt root@techshare.vn [~]#chown -R ubnt:ubnt /opt/UniFi
5. Create Startup Script with Systemd
vi /etc/systemd/system/unifi.service --- # # Systemd unit file for UniFi Controller # [Unit] Description=UniFi AP Web Controller After=syslog.target network.target [Service] Type=simple User=ubnt WorkingDirectory=/opt/UniFi ExecStart=/usr/bin/java -Xmx1024M -jar /opt/UniFi/lib/ace.jar start ExecStop=/usr/bin/java -jar /opt/UniFi/lib/ace.jar stop SuccessExitStatus=143 [Install] WantedBy=multi-user.target ---
6. Configure Firewalld
systemctl stop firewalld.service vi /etc/firewalld/services/unifi.xml --- <?xml version="1.0" encoding="utf-8"?> <service version="1.0"> <short>unifi</short> <description>UniFi Controller</description> <port port="8081" protocol="tcp"/> <port port="8080" protocol="tcp"/> <port port="8443" protocol="tcp"/> <port port="8880" protocol="tcp"/> <port port="8843" protocol="tcp"/> <port port="10001" protocol="udp"/> <port port="3478" protocol="udp"/> </service> --- systemctl start firewalld.service firewall-cmd --set-default-zone=home # You can use one of the other zones, if you like. I prefer using home instead of the default "public", just adjust accordingly below. firewall-cmd --permanent --zone=home --change-interface=eth0 # I only have one active interface on my UniFi server, eth0. This should be the interface that UniFi will be using. firewall-cmd --permanent --zone=home --add-service=unifi
7. Enable on Startup
systemctl enable unifi.service
8. And to finish CLEANUP
rm -rf ~/UniFi.unix.zip systemctl reboot
9. To access the webUI
