Installing the Appliance
Installing the Appliance
Installing the Appliance on a Physical Server
If you are installing the Appliance on a physical server, you are required to enter the BIOS and modify some settings:
- Power on the server and enter the BIOS setup. This is usually done by pressing down [F2] or [DEL] keys before the computer attempts to boot the operating system. Explore the exact method to enter BIOS setup in your user manual.
- In the system settings, set the date and time of the system to match the current UTC (Coordinated Universal Time). Time precision is important to ensure consistency of data in the system. In order to keep time precision, you may configure the Appliance to use NTP servers as described in Network Parameters section below.
- Insert your copy of the the Nexthink V5 Installation DVD into your DVD Drive.
- Go to boot sequence (or boot order) settings and select the CD/DVD Drive to be the first device in the list of bootable devices. The system will boot from the Nexthink Installation DVD next time.
- Exit BIOS setup saving your changes.
Installing the Appliance in Virtual Server
If you are installing the Appliance in a virtual machine, the exact installation steps will depend on your virtualization platform. Here, we assume that you are familiar with the creation and configuration of virtual machines on your virtualization platform. If this is not the case, please take your time to learn how to use it. Independently of the virtualization platform that you are using, you must perform the following operations:
- Create a new virtual machine and select Linux 2.6 64-bit as the guest operating system.
- Insert the Nexthink V5 Installation DVD into the DVD drive of the host machine or, alternatively, copy the ISO image of the Nexthink V5 Installation DVD to a file system accessible to the host machine.
- Indicate your virtualization platform to use the DVD drive or the copied ISO image for booting the your newly created virtual machine for the first time.
- Start the virtual machine.
- Explore the user manual of your virtualization platform to find out how to synchronize the clock of the virtual machine to the clock of the host, if the host has precise timing. Alternatively, use NTP servers as described in Network Parameters section below.
Finishing the Installation
When on of the previous steps have been completed, the installation is identical for both physical or virtual servers. If everything went well, your system will now boot from the Nexthink V5 Installation DVD and you should see the Nexthink V5 splash screen.
- Press [ENTER] or wait for the 6 seconds timeout.
- After the splash screen, the End-User License Agreement is displayed. Accept to proceed
- In the following screen, you are warned that your hard disk will be erased during the installation procedure and that all data on it will be lost. Ensure that you do not have any valuable data on the hard disk and type Yes to proceed.
- The installation procedure whether you want to configure the network. If you wish to configure the network, a small dialog box will open where you may change the default IP address, subnet mask and default gateway. If you choose not to configure your network, the Appliance will take these default values. These can be modified as described in Network Parameters section below.
- Select the type of keyboard that is attached to your computer. By default, US keyboard is highlighted.
- Choose a secure password for the root user, ensure that it is kept in a safe place or use another method to make sure that it is not forgotten.
- The installation procedure is formating your hard disk and installing the necessary software packages.
- Once the installation has finished, remove the Nexthink V5 Installation DVD from the DVD drive or detach the ISO image from your virtualization platform and reboot the system.
Appliance Network Parameters
- If nothing has been specified during the installation, the Appliance server default IP address is 192.168.0.99 with a netmask of 255.255.255.0. To access its web-based configuration page, configure your computer to have the static IP address on the same subnet as the Engine default IP address, that is, 192.168.0.0/24. If you modified the network configuration of the server during the installation of the Engine, use your modified configuration values instead of the defaults and then the following steps.
- With a cross-over cable, connect the first Ethernet port on the server to the Network Interface Port (NIC) on the client computer. Alternatively, if there is a switch between the client PC and the server, connect both devices to it.
- Test the network connectivity between the client computer and the server using ping command. Execute the ping test using the default IP address of the Engine: 192.168.0.99. If the ping test fails with the first Ethernet port, repeat the test by connecting to each available Ethernet port on the server. By default, the first Ethernet port is used for testing the network connections, but some servers may behave differently.
- Using a web browser and type the following URL in the address field, using the HTTPS protocol: https://192.168.0.99:99. Note that if you just type the IP address 192.168.0.99:99, your web browser will use HTTP by default and you will get a blank page. Ensure that you specify the HTTPS protocol.
- Accept the SSL certificate from Nexthink. Depending on the web browser, you may have a warning about the certificate. Accept it and you will arrive at the Console welcome screen:
- Enter the Login Username as admin and Password also as admin to connect to the Appliance Web Console
- Go to Appliance > Network parameters to enter or modify the Hostname, Domain name, DNS servers (IP addresses), Timezone and NTP time servers and then select Save.
- Go to Appliance > Network interfaces, click on Edit and configure the IP address, the subnet mask and the default gateway as required (Note: Nexthink does not recommend DHCP).
- Review the desired network settings before clicking on the Save button. Clicking on this button will save the settings, and the current connection will be lost. To reconnect to the web-console, use the Engine`s newly configured IP address (ensure you have accordingly modified the client computer network parameters to match the Appliance subnet).
Appliance Proxy configuration
Software installation/updates and access to the Nexthink Library are done using HTTP and HTTPS access. If those connections need to go through a proxy, go to Appliance > Proxy.
- Check the Enable the proxy configuration.
- Configure the server name or IP address and port number.
- If required, set a username and password.
- Choose the authentication method (Note: For software updates, only basic authentication method is supported).
- To check that the Proxy chain is working and that the supplied parameters are correct, we recommend to test them by clicking on the Test button.
- Click on Save to store the Proxy data into the configuration file permanently.
If you are required to manually configure the proxy to access the host where the Nexthink Application Library resides, the URL accessed by the Nexthink Engine is:
- https://application-library-v5.nexthink.com (IP address 184.108.40.206) on TCP port 443 (HTTPS).
If you are required to manually configure the proxy to access the host where the Nexthink Updates reside, the URL accessed by the Nexthink Engine is:
- http://updates-v5.nexthink.com and http://updates-centos-v5.nexthink.com (IP address 220.127.116.11) on TCP port 80 (HTTP).
Nexthink Engine & Portal installation
Installation can be done either by using our online repository or, if the Appliance is not connected to the Internet, by uploading an offline installation package. When installing both the Engine and the Portal, especially during upgrading, always install or upgrade your Engines first and make sure that the update was successful. In that way, it is easier to roll-back to the original situation if something goes wrong.
From the Web Console, go to Appliance > Install:
- Select if you want to use the Nexthink online repository or a file. In this second case, the file can be downloaded from the latest releases of our support portal. In the desired release page, look for the download of the Nexthink installation package (tgz file).
- Choose to install the Engine, the Portal or both. Note that it is not recommended to install the Engine and the Portal on the same Appliance, except for small setups.
- Accept the license agreement.
- Click on install.
Please note that the installation process can be started only once. This page is no longer available after the first installation. Go to the Update page for upgrading your Appliance instead.
