bootOutput="bl.out"

04

rm -f $bootOutput//删除b1.out文件

05

./cloudify.sh "bootstrap-cloud ec2" > $bootOutput 2>&1//运行./cloudify.sh bootstrap-cloud ec2并将输出到b1.out和标准输入重定向到标准输出。

06

searchString="Rest service is"

07

selectedText=`grep "${searchString}" $bootOutput`//查找b1.out中"Rest service is"的行赋给selectedText

08

rawValue=`echo ${selectedText} | awk '{print $6}'`//将selectedText中第六个域(以空格或tab分割)赋给rawValue

09

restURL="${rawValue%?}"//linux字符串操作，删除rawValue的最后一个字符后执行，即提取restURL

10

echo "1st restURL is ${restURL}" >> $bootOutput 2>&1//打印并重定向到b1.out和标准输出

11

  

12

# If there are two management machines (and in production, we recommend it...),

13

# you'll have two Rest URLs

14

rawValue=`echo ${selectedText} | awk '{print $12}'`//和上面一样

15

rest2URL="${rawValue%?}"

16

echo "2nd restURL is ${rest2URL}" >> $bootOutput 2>&1

17

  

18

# Now set the restURL value in the service context attributes (global scope ,

19

# so it'll be available for all applications) :

20

# e.g. : set-attributes -scope global '{"restURL":"${restURL}", "rest2URL":"${rest2URL}"}'

21

./cloudify.sh "connect ${restURL};set-attributes -scope global '{\"restURL\":\"${restURL}\", \"rest2URL\":\"${rest2URL}\"}'" >> $bootOutput 2>&1//连接restURL并将restURL设为所有应用的全局属性

22

  

23

# Just checking that it's there :)

24

./cloudify.sh "connect ${restURL};list-attributes" >> $bootOutput 2>&1//测试连接并显示所有属性

25

  

26

# Now you can install any application

27

# and access the restURL attribute (or "rest2URL")

28

# e.g.: In a groovy lifecycle event handler :

29

#  def restURL = context.attributes.global["restURL"]

30

# ./cloudify.sh "connect ${restURL};install-application PATH_TO_APPLICATION" >> $bootOutput 2>&1
