1.查看当前计算节点命名方式如下
[[email protected] ~]# rocks list host
HOST MEMBERSHIP CPUS RACK RANK RUNACTION INSTALLACTION
cluster: Frontend 1 0 0 os install
compute-0-0: Compute 1 0 0 os install
compute-0-1: Compute 1 0 1 os install
2.现在要把compute-0-*更改为node*,步骤如下
◆在任何路径下，创建一个名为ReName.sh的脚本，内容如下
[[email protected] AddHost]# cat ReName.sh
#!/bin/bash
ORDER=0
SUM=2 //共有多少个节点
NEW=1
##
while [ $ORDER -lt "$SUM" ]; do \
rocks set host name compute-0-$ORDER node$NEW; \
rocks set host interface name node$NEW eth0 node$NEW; \
let ORDER++; \
let NEW++; \
done
#
#
##Sync Config
rocks sync config
#
#
SUM=2
NEW=1
#
##Set For hosts file
for i in `seq $NEW $SUM`;do ssh node$i sed -i \
-e "s/compute-0-.*.local/node$i.local/g" \
-e "s/compute-0-.*/node$i/g" \
/etc/hosts;done
#
for i in `seq $NEW $SUM`;do ssh node$i hostname node$i.local;done
#
for i in `seq $NEW $SUM`;do ssh node$i sed -i "/HOSTNAME/c\HOSTNAME=node$i.local" /etc/sysconfig/network;done
注：脚本内容根据实际情况更改
例如：现在共有10个节点，现在需要把compute-0-0到compute-0-9，重命名为node1到node10，步骤如下
1.脚本中需要更改的地方，如下面红色字体处所示
[[email protected] AddHost]# cat ReName.sh
#!/bin/bash
ORDER=0
SUM=10
NEW=1
##
while [ $ORDER -lt "$SUM" ]; do \
rocks set host name compute-0-$ORDER node$NEW; \
rocks set host interface name node$NEW eth0 node$NEW; \
let ORDER++; \
let NEW++; \
done
#
#
##Sync Config
rocks sync config
#
#
SUM=10
NEW=1
#
##Set For hosts file
for i in `seq $NEW $SUM`;do ssh node$i sed -i \
-e "s/compute-0-.*.local/node$i.local/g" \
-e "s/compute-0-.*/node$i/g" \
/etc/hosts;done
#
for i in `seq $NEW $SUM`;do ssh node$i hostname node$i.local;done
#
for i in `seq $NEW $SUM`;do ssh node$i sed -i "/HOSTNAME/c\HOSTNAME=node$i.local" /etc/sysconfig/network;done
2.执行该脚本即可
[[email protected] AddHost]# sh ReName.sh
