* Izvēlieties sistēmas diska avotu. Šis ir svarīgs punkts, jo iespējamas dažādas konfigurācijas. Apskatīsim dažas no tām:
+
* Select the system disk source. This is an important point because many possible configurations. Let's look at some of them:
−
** Izvēloties instances palaišanas avotu "Image", nepieciešams norādīt arī diska OS šablonu, kas atrodams zemāk. Aprakstīsim "Create New Volume" opcijas variācijas:
+
** Choosing Instance launch source "Image", you need to specify the disk OS template, which can be found below. We describe the "Create New Volume" option variations:
−
*** Ja pie izvēlnes "Create New Volume" ir "No", instance startēsies uz fiziskā servera vietējiem (local) diskiem, kuri ir SSD. Šo izvēlni iesakām izmantot, kad nepieciešama instancei liela disku veiktspēja.
+
*** If the menu "Create New Volume" is "No", the instance will start on a physical server for local drives, which are the SSD. This is recommend  if you require high-performance drive.
−
*** Ja pie izvēlnes "Create New Volume" ir "Yes", instance startēsies no disku masīva ar HDD SATA savienojumu. Papildus jānorāda vēlamā sistēmas diska izmērs (!!! dažiem serveru šābloniem kā minimālais diska izmērs ir 2 un vairāk GB).
+
***If the menu "Create New Volume" is "Yes", the instance will start on disk array with SATA HDD connection. In addition you have to specify the desired size of the system disk (!!! for some server templates minimum disk size is more than 2 GB).
−
** Izvēloties instances palaišanas avotu "Instance Snapshot", instance startēsies uz vietējiem servera SSD diskiem.
+
** Choosing Instance launch source "Snapshot Instance" it will start on local server SSD drives.
−
** Izvēloties instances palaišanas avotu "Volume", iespējams palaist instanci no diska sējuma, kas tika izveidots iepriekš un kurš ir atzīmēts kā palaižams (Bootable). Mēs iesakām vienmēr izvēleties opciju "Delete Volume on Instance Delete" uz "No". Sīkāk par to kā izveidot SAS vai SATA diska sējumu, varat atrast [[Hostnet_OpenStack_Cloud_diska_sējuma_veidošana|TE]].
+
** Choosing Instance launch source "Volume", it is possible to run an instance of the disk volume that was created previously and which is marked as (Bootable). We recommend that you always choose the option "Delete Volume Instance on Delete" to "No". More information about how to create a SAS or SATA disk volume, you can find [[Hostnet_OpenStack_Cloud_diska_sējuma_veidošana/en | Here]].
−
** Izvēloties instances palaišanas avotu "Volume Snapshot", instance tik veidota no diska sējuma momentuzņēmuma.
+
** Choosing Instance launch source "Volume Snapshot", the instance will be formed from the disk volume snapshot.

* Izvēlieties instances resursus. Patreiz mums ir pieejami kopēji resursu piedāvājumi gan SSD uz vietējiem diskiem, gan diska sējumiem, kuri ir ar atšķirīgu diska izmēru kā norādīts pie resursu izvēlnes. Ja instances palaišanas avots tika norādīts "Image", tad instances diska izmērs būs kā norādīts pie resursu izvēlnes, ja avots tika norādīts "Volume", diska izmērs būs nemainīgs, tas ir, tāds pats kā tas ir definēts pie diska sējuma.
+
* Choose Instance resources. Currently we can offer SSD on local disks or combination of disks which are indicated on resource menu. If the instance startup source is “ Image “ then the instance disk size will be the same as at the resources menu. If the instance startup source is "Volume", then the disk size will be the same, as it is defined on the disk combination.

* Izvēlieties tīklu savai instancei. Tīklam jābūt jau izveidotam. Par to kā izveidot tīklu un virtuālo rūteri, varat atrast informāciju [[Hostnet_OpenStack_Cloud_virtuālā_tīkla_veidošana|TE]].
+
* Choose a network for your department. Network should have already been created. On how to set up a network and virtual routers, you can find information [[Hostnet_OpenStack_Cloud_virtuālā_tīkla_veidošana/en | Here]].

* Izvēlaties SSH atslēgu. Tai ir jābūt iepriekš izveidotai vai arī ieimportētai. Sīkāk informāciju par to atrodama [[Hostnet_OpenStack_Cloud_ssh_atslēgas_ģenerēšana|TE]].
+
* Select the SSH key. It must be made previously or already imported. More information about it can be found [[Hostnet_OpenStack_Cloud_ssh_atslēgas_ģenerēšana/en | Here]].

−
* Instance gatava palaišanai. Instances palaišanas process sāksies nospiežot "Launch Instance".
+
* Instance is ready to run. Instance startup process will start by pressing the "Launch Instance".
  
−
* Instancei nepieciešams pievienot publisko IP adresi, to var veikt dažādos veidos, viens no variantiem aprakstīts [[Hostnet_OpenStack_Cloud_publiskās_ip_adreses_piešķiršana_instancei|TE]].
+
* You need to add a public IP address to instance, this can be done in various ways, one of the options described [[Hostnet_OpenStack_Cloud_publiskās_ip_adreses_piešķiršana_instancei/en | here]].
  
−
* Pēc publiskās IP adreses piešķiršanas, pieslēgšanās instancei notiek ar SSH atslēgu. Linux un MacOS sistēmās tas paveicams ar komandu:
+
* After adding a public IP address, connection to the instance occurs with the SSH key. Linux and MacOS systems it is done with the command:
  
−
  $ ssh -i cels_lidz_atslegai root@servera_ip_adrese
+
  $ ssh -i cels_till_key
 +
root@server_ip_address
  
−
Piemēram:
+
For example:
  
 
  $ ssh -i demo-ssh-key-1.pem root@89.111.XX.YYY
 
  $ ssh -i demo-ssh-key-1.pem root@89.111.XX.YYY
  
−
Daži OS šabloni neļauj slēgties klāt izmantojot root lietotāju, ja tā notiks, uzrādīsies paziņojums, līdzīgs kā mūsu piemērā ar CentOS sistēmu:
+
Some OS templates do not allow to connect as “root” user, if it happens, will appear message similar to our example with CentOS systems:
  
 
  Please login as the user "centos" rather than the user "root".
 
  Please login as the user "centos" rather than the user "root".
−
Lai pieslēgtos, izmantojiet lietotāju, kuru uzrāda paziņojumā:
+
To log in, use the user presented by the statement:
  
 
  $ ssh -i demo-ssh-key-1.pem centos@89.111.XX.YYY
 
  $ ssh -i demo-ssh-key-1.pem centos@89.111.XX.YYY

Lai pieslēgtos no Windows sistēmām izmantojot putty, Jums nāksies pārģenerēt RSA atslēgu uz putty saprotamu, kā to veikt var apskatīt te: http://www.electrictoolbox.com/PuTTY-rsa-dsa-keys/
+
To connect from Windows systems using putty, you will have to Regenerate RSA key to putty to understandable version. How to do it:

It is easy to create Instance with a few clicks in Hostnet OpenStack Cloud service. But first of all you have to decide on which drives your instance will work ( HDD SAS, HDD SATA vai SSD). Secondly do you need a new internal network and what are requirements about CPU and RAM? Below we will describe all possible options.

  • You can Launch instance in section "Instance" by clicking on "Launch instance".

  • Insert a name of new instance

  • Select the system disk source. This is an important point because many possible configurations. Let's look at some of them:
    • Choosing Instance launch source "Image", you need to specify the disk OS template, which can be found below. We describe the "Create New Volume" option variations:
      • If the menu "Create New Volume" is "No", the instance will start on a physical server for local drives, which are the SSD. This is recommend if you require high-performance drive.

    • Choosing Instance launch source "Snapshot Instance" it will start on local server SSD drives.
    • Choosing Instance launch source "Volume", it is possible to run an instance of the disk volume that was created previously and which is marked as (Bootable). We recommend that you always choose the option "Delete Volume Instance on Delete" to "No". More information about how to create a SAS or SATA disk volume, you can find Here.
    • Choosing Instance launch source "Volume Snapshot", the instance will be formed from the disk volume snapshot.
