- 验证 Traceback 在日志文件出现次数
grep -F "Traceback" -R logs/error_log
- 普通用户登录时可能报 sftp 权限错误，可以先给改目录分配用户权限
chown -R username:username logs/error_log
- 如果不方便使用 chown 授权，但是可以当你用普通账号登录后可以切换成 root 用户，也可以这样写（就是 sudo 切换一下）：
client = paramiko.SSHClient() | |
client.set_missing_host_key_policy(paramiko.AutoAddPolicy()) | |
client.connect(hostname, port, username, password, compress=True) | |
if username != 'root': | |
ssh = client.invoke_shell() | |
time.sleep(0.1) | |
ssh.send('sudo su \n') | |
buff = '' | |
while not buff.endswith('Enter domain (xxx) password:'): # 这里改成你自己的 | |
resp = ssh.recv(9999) | |
buff += resp | |
ssh.send(password) | |
ssh.send('\n') | |
buff = '' | |
while not buff.endswith('# '): | |
resp = ssh.recv(9999) | |
buff += resp | |
ssh.send(remote_command) | |
ssh.send('\n') | |
buff = '' | |
while not buff.endswith('# '): | |
resp = ssh.recv(9999) | |
buff += resp | |
client.close() | |
result = buff | |
else: | |
stdin, stdout, stderr = client.exec_command(remote_command) | |
result = stdout.read() |
