MySQL Cluster驗證管理節點配置中內存是否超標的腳本

MySQL Cluster驗證管理節點配置中內存是否超標的腳本   驗證管理節點config.ini參數配置的shell腳本，看memory是否超標，運行的時候需要附帶上面data node id， 而且cluster要處於工作狀態，最起碼manage node和data node要處於啟動狀態   run check_memery.sh 腳本內容下：

#!/bin/bash


usage()
{
   echo "-----------------------------"
   echo "Usage:$(basename $0) NodeId"  #數據節點的ID
   echo "-----------------------------"
   echo
   exit 1
}


print_size ()
{
string1=$(echo $1|sed -e :a -e 's/^.\{1,40\}$/&./;ta')
echo -e "$string1 (MB):\t$2"
}






if [ "$1" == "" ]; then
    usage
fi
string1=$(echo $1|egrep "^[0-9]+$")
if [ "$1" != "$string1" ]; then
    usage
fi
