python 通过SSHTunnelForwarder隧道连接redis
背景:我司Redis服务器使用的亚马逊服务,本地需要通过跳板机,然后才有权限访问Redis服务。
两种思路:
1、通过SSHTunnelForwarder,paramiko模块,先ssh到跳板机,然后在跳板机上(或者内部服务器上),获取到权限,然后远程Redis。
思路一:
private_key_path = /Users/xxx/.ssh/id_rsa
rsaKey = paramiko.RSAKey.from_private_key_file(private_key_path)
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(跳板机或者内网服务器IP或者域名, 22, username, rsaKey)
stdin, stdout, stderr = ssh.exec_command(redis-cli -h {} -p {} -n {} {}.format(host, port, db, script))
result = stdout.read(), stderr.read()
for out in result: # 需要通过循环拿到stdout,否则为空值
if out:
return out
类似:
import paramiko
from sshtunnel import SSHTunnelForwarder
with SSHTunnelForwarder(
(REMOTE_SERVER_IP, 443),
ssh_username="",
ssh_pkey="/var/ssh/rsa_key",
ssh_private_key_password="secret",
remote_bind_address=(PRIVATE_SERVER_IP, 22),
local_bind_address=(0.0.0.0, 10022)
) as tunnel:
client = paramiko.SSHClient()
client.load_system_host_keys()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(127.0.0.1, 10022)
# do some operations with client session
client.close()
print(FINISH!)
方法二:
Advice:
一般跳板机是个干净的机器,公司内网服务器大部分不会给权限或者有redis-client客户端,因此推荐使用方法2。
