  1. #host 檔案更換IP對映，需要手工定義主機IP
  2. $db_host1 = "192.168.1.1"
  3. $db_host2 = "192.168.1.2"
  4. $host_file = "C:\Windows\System32\drivers\etc\hosts"
  5. $db_name = "db.test.com"
  9. $v_db_name = Select-String -Path $host_file -Pattern $db_name
  10. $v_db = $v_db_name -split "\s+"
  11. $v_db_ip = $v_db -split ":"
  12. $v_db_ip_now = $v_db_ip[3]
  15. if ( $v_db_ip_now -like $db_host1){
  16. $sw_dbhost = $db_host2
  17. }
  18. else {
  19. $sw_dbhost = $db_host1
  20. }
  22. #切換IP函式
  23. function f_switch_db{
  24. write-host "切換前資料庫IP為$v_db_ip_now"
  25. (Get-Content $host_file) -replace $v_db_ip_now,$sw_dbhost | Set-Content $host_file
  26. write-host "切換後資料庫IP為$sw_dbhost"
  27. }
  31. $title = "切換資料庫IP"
  32. $message = "你希望切換資料庫IP嗎?"
  33. $yes = New-Object System.Management.Automation.Host.ChoiceDescription "&Yes", `
  34. "準備切換IP為$sw_dbhost"
  35. $no = New-Object System.Management.Automation.Host.ChoiceDescription "&No", `
  36. "不切換IP."
  37. $options = [System.Management.Automation.Host.ChoiceDescription[]]($yes, $no)
  38. $result = $host.ui.PromptForChoice($title, $message, $options, 0)
  39. switch ($result)
  40. {
