OPENNODE WEB GUI (OMS)

INSTAL OPENNODE WEB GUI (OMS)

Layanan Manajemen OpenNode, atau OMS, digunakan untuk mengelola OpenNode melalui GUI berbasis web. OMS tidak diinstal secara default dan harus ditambahkan setelah instalasi. OMS tidak dipasang sebagai paket menggunakan yum, tetapi merupakan wadah OpenVZ host. Wadah ini kemudian terdaftar dengan sistem OpenNode dan kemudian dapat digunakan untuk mengelola itu.

Anda harus memiliki OpenNode diinstal Sebelum memasang OMS.

OpenNode juga memiliki TUI, ini adalah utilitas manajemen berbasis teks yang dapat digunakan untuk membuat dan mengelola mesin virtual baru dan membantu Anda menginstal OMS.

Login ke sesi ssh OpenNode Anda dan jalankan perintah opennodeuntuk memulai TUI.

Select OMS (beta) on the right to be given a set of options for getting the OMS up and running.

Select Download OMS image and press ENTER .

Select Yes to start downloading the OMS virtual machine archive.

The download may take a while. If you quit the download and restart it, it will resume where it left off and not download the same part of the file twice.

Press OK when the download completes. 

Back in the main menu, select Install OMS image to open the settings for the new virtual machine. You will need to enter the following settings

•  VSwap size (GB):  set to 1GB
• Number of CPUs:  set to two. The OMS can be quite CPU hungry when performing certain tasks.
• CPU usage limit (%):  set to 100% to allow all of the assigned CPU to be used.
• Disk size (GB):  as very little is stored on the OMS root device you will not need to assign it much space. 5GB should be sufficient.
• IO Priority: although very little IO will occur on the OMS container, it is best to give it the priority over other containers.
• Hostname :  set this to the hostname you would like to use for the OMS container.
• IP-address: set this to the IP address for the container to use.
• Nameserver:  set this to the IP address of your networks DNS server.
• Root password:  enter a password which the OMS container will use for it’s root account. This is not the password which will be used to access the web GUI.
• Root password x2:  Repeat your password to confirm it.
• Start VM select this and press SPACE to start the container after it has been created.
• Start on boot select this and press SPACE to enable the container to start up after your OpenNode server starts up after a reboot.

Click Create VM once you have entered all the required settings.

You will be taken back to the OpenNode Management Service (OMS) operations  menu when your container has been created and started. The final step is to register the OMS with the OpenNode server. Select Register with OMS and enter the OMS server address – this is the IP you just created in the above step. Make sure the OMS server port  remains on the default of 4506 .

You can now log into your OMS web administration with the below username and password. The URL to use is the IP address you created when creating the container for the OMS. You must also access the page over HTTPS, for example https://10.10.10.8
