如何在不与XShell断开连接的情况下在Linux AWS上切换弹性IP？

Question

我正在使用XShell访问Linux AWS。我知道如何用Ruby切换弹性IP地址，但是当我这样做时，XShell与AWS的连接被破坏了。

这是script.rb我通过XShell使用ruby script.rb命令在AWS上运行：

require 'json'
require 'pp'

region = 'REGION NAME'
aws_access_key_id = 'SECRET KEY ID'
aws_secret_access_key = 'SECRET ACCESS KEY'
credentials = Aws::Credentials.new(aws_access_key_id, aws_secret_access_key)
client = Aws::EC2::Client.new(
    region: region,
    credentials: credentials
)
pp client
p '==='

describeAddresses = `aws ec2 describe-addresses`
awsHash = JSON.parse(describeAddresses)
pp awsHash
p '==='

getInstanceID = `wget -O - 'http://MY.AWS.IP.HERE/latest/meta-data/instance-id' 2>/dev/null`
instanceID = getInstanceID.split("\n")[-1]
pp instanceID
p '==='

resp = client.allocate_address({
  domain: "vpc", # accepts vpc, standard
})
pp resp
p '==='

resp2 = client.associate_address({
    instance_id: instanceID,
    allocation_id: resp['allocation_id'],
    allow_reassociation: true#,
})
pp resp2
p '==='
