04
rm -f $bootOutput//刪除b1.out文件
05
./cloudify.sh "bootstrap-cloud ec2" > $bootOutput 2>&1//運行./cloudify.sh bootstrap-cloud ec2並將輸出到b1.out和標准輸入重定向到標准輸出。

searchString="Rest service is"
07
selectedText=`grep "${searchString}" $bootOutput`//查找b1.out中"Rest service is"的行賦給selectedText
08
rawValue=`echo ${selectedText} | awk '{print $6}'`//將selectedText中第六個域(以空格或tab分割)賦給rawValue
09
restURL="${rawValue%?}"//linux字符串操作，刪除rawValue的最後一個字符後執行，即提取restURL
10
echo "1st restURL is ${restURL}" >> $bootOutput 2>&1//打印並重定向到b1.out和標准輸出

# 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 $12}'`//和上面一樣
15
rest2URL="${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//連接restURL並將restURL設為所有應用的全局屬性
22
23
# Just checking that it's there :)
24
./cloudify.sh "connect ${restURL};list-attributes" >> $bootOutput 2>&1//測試連接並顯示所有屬性
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
