Python - paramiko 模块远程执行ssh 命令 nohup 不生效的问题解决
1、使用 paramiko 模块ssh 登陆到 linux 执行nohup命令不生效
# 执行命令
def command(ssh_config, cmd, result_print=None, nohup=False):
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(hostname=ssh_config.hostname, port=ssh_config.port, username=ssh_config.username,
password=ssh_config.password)
print(ssh_config.hostname + '@' + ssh_config.username, ': ', cmd)
stdin, stdout, stderr = ssh.exec_command(cmd)
result = stdout.read()
if result_print:
lines = read_unicode(result)
for line in lines:
print(line)
ssh.close()
因为执行完毕后，shell 会立即关闭通道
2、稍作修改，使用 invoke_shell
# 执行命令
def command(ssh_config, cmd, result_print=None, nohup=False):
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(hostname=ssh_config.hostname, port=ssh_config.port, username=ssh_config.username,
password=ssh_config.password)
print(ssh_config.hostname + '@' + ssh_config.username, ': ', cmd)
if nohup:
cmd += ' & \n '
invoke = ssh.invoke_shell()
invoke.send(cmd)
# 等待命令执行完成
time.sleep(2)
else:
stdin, stdout, stderr = ssh.exec_command(cmd)
result = stdout.read()
if result_print:
lines = read_unicode(result)
for line in lines:
print(line)
ssh.close()
