用sandbox 搭建InnoDB Cluster環境時遇到如下問題：
mysql-js> dba.deploySandboxInstance(3310)
A new MySQL sandbox instance will be created on this host in
/root/mysql-sandboxes/3310
Warning: Sandbox instances are only suitable for deploying and
running on your local machine for testing purposes and are not
accessible from external networks.
Please enter a MySQL root password for the new instance:
Deploying new MySQL instance...
Dba.deploySandboxInstance: (RuntimeError)
通過dba.help('deploySandboxInstance')看到RuntimeError的解釋，但還是不知道該怎麼處理
mysql-js> dba.help('deploySandboxInstance')
EXCEPTIONS
RuntimeError: f SSL support can be provided and ignoreSslError: false.
DESCRIPTION
- ignoreSslError: Ignore errors when adding SSL support for the new instance, by default: true.
檢查mysqlshell的日誌：
tail -f $/HOME/.mysqlsh/mysqlsh.log
ImportError: can't decompress data; zlib not available
發現python2.7 環境中缺少zlib，ssl
安裝相關依賴：yum -y install zlib*，openssl
重新編譯python後，重試，正常。
