Rocks Quick Add Node

1. Create a folder under any path such as: Addhost

[Email protected] ~]# mkdir addhost

2. Create a addhost.sh script file and a Mac.txt host MAC address list under the Addhost directory

[[email protected] addhost] #touch addhost.sh mac.txt

3. Where the addhost.sh script content is as follows

#!/bin/baship=254rank=0node=1count=6                              // 6 meaning to add 5 nodes cores=1                              //1 cores per node # # #Add  host #for  MAC in  ' cat ./mac.txt ' dowhile [  $NODE  -lt  "$COUNT"  ];  do echo  "Adding host node$node.";  rocks add host node$node cpus= $CORES  membership=compute os=linux rack =0 rank= $RANK;  rocks add host interface node$node iface=eth0 ip= 10.1.255. $IP  subnet=private name=node$node mac= $MAC; let ip--; let rank++;  let node++; break; donedone## #Set  host boot actionrocks set host boot compute action=install## #Sync  Configrocks sync  Config

Note: The above script needs to change according to the actual situation

For example: To add 10 nodes, 8 cores per node, the steps are as follows

1. See the comments where the script needs to be changed

#!/bin/baship=254rank=0node=1count=11                              // Change Place 1cores=8                               //Change Place 2## #Add  host#for  MAC in  ' cat ./mac.txt ' dowhile [  $NODE  -lt  "$COUNT"  ]; do  echo  "Adding host node$node.";  rocks add host node$node cpus= $CORES  membership=compute os=linux rack =0 rank= $RANK;  rocks add host interface node$node iface=eth0 ip= 10.1.255. $IP  subnet=private name=node$node mac= $MAC; let ip--; let rank++;  let node++; break; donedone## #Set  host boot actionrocks set host boot compute action=install## #Sync  Configrocks sync  Config

2.mac.txt Add the MAC address of these 10 nodes in one line, such as

[email protected] addhost]# cat Mac.txt

00:50:56:33:b5:c0

00:50:56:33:b5:c1

00:50:56:33:b5:c2

00:50:56:33:b5:c3

00:50:56:33:b5:c4

00:50:56:33:b5:c5

00:50:56:33:b5:c6

00:50:56:33:b5:c7

00:50:56:33:b5:c8

00:50:56:33:b5:c9

3. Execute the script to

[Email protected] addhost]# sh addhost.sh

Adding Host Node1.

Adding Host Node2.

Adding Host Node3.

Adding Host node4.

Adding Host Node5.

Adding Host Node6.

Adding Host Node7.

Adding Host Node8.

Adding Host Node9.

Adding Host Node10.

4. View the list of added hosts

[email protected] addhost]# Rocks list Host

Node2:compute 8 0 1 OS Install

Node3:compute 8 0 2 os Install

Node4:compute 8 0 3 OS Install

Node5:compute 8 0 4 OS Install

Node7:compute 8 0 6 OS Install

Node8:compute 8 0 7 OS Install

Node9:compute 8 0 8 OS Install

Node10:compute 8 0 9 os Install

5. Each node starts from the network, can obtain the corresponding IP, and starts to install the system
