Question

deploySHPath = os.path.join(BASE_DIR,"static","constantfiles","jenkins-java-conf.sh")
rollbackSHPath = os.path.join(BASE_DIR,"static","constantfiles","jenkins-java-conf-backup.sh")
list_fail = []
t=paramiko.Transport((ip,SSH_PORT))
key=paramiko.RSAKey.from_private_key_file(PKEY)
sftp=paramiko.SFTPClient.from_transport(t)
sftp.put(deploySHPath,"/tmp/jenkins-java-conf.sh")
sftp.put(rollbackSHPath,"/tmp/jenkins-java-conf-backup.sh")
sftp.put(confPath,"/tmp/%s" % conf_name)
t.close()

#paramiko.SFTPClient.from_transport(t)这行抛出异常，异常信息为：
#SSH session not active

Answer 1

脑子进水了，少写一行....

key=paramiko.RSAKey.from_private_key_file(PKEY)
t=paramiko.Transport((ip,SSH_PORT))
t.connect(username=SSH_HOST_NAME, pkey=key)
sftp=paramiko.SFTPClient.from_transport(t)
