PHP ssh2.sftp停止工作

是指在PHP中使用ssh2扩展的sftp功能时出现了无法正常工作的情况。ssh2扩展是PHP提供的一个用于与远程服务器进行安全通信的扩展,其中的sftp功能用于进行文件传输。

可能的原因包括:

  1. 服务器配置问题:检查服务器的SSH配置,确保SSH服务正常运行,并且允许使用sftp进行文件传输。
  2. PHP扩展问题:确保已经正确安装了ssh2扩展,并且在PHP配置文件中启用了该扩展。
  3. 权限问题:检查PHP进程所在的用户是否具有足够的权限进行sftp操作,包括读取和写入目标文件夹的权限。
  4. 连接问题:检查与远程服务器的连接是否正常,包括服务器地址、端口号、用户名和密码等信息是否正确。

针对这个问题,可以尝试以下解决方案:

  1. 检查服务器配置:确保服务器的SSH服务正常运行,并且允许使用sftp进行文件传输。可以通过在终端上手动使用sftp命令测试连接是否正常。
  2. 检查PHP扩展:确认已经正确安装了ssh2扩展,并且在PHP配置文件中启用了该扩展。可以通过在PHP代码中使用phpinfo()函数查看扩展是否加载成功。
  3. 检查权限:确保PHP进程所在的用户具有足够的权限进行sftp操作。可以通过更改文件夹的权限或者将PHP进程所在的用户添加到文件夹的访问控制列表中来解决权限问题。
  4. 检查连接信息:确认与远程服务器的连接信息是否正确,包括服务器地址、端口号、用户名和密码等。可以尝试使用其他SSH客户端工具连接服务器,以验证连接信息的正确性。

如果以上解决方案都无法解决问题,可以考虑使用其他的PHP库或者工具来替代ssh2扩展进行sftp操作。例如,可以使用phpseclib库或者使用shell命令来执行sftp操作。

系统运维工程师的法宝:python pa

安装:pip install Paramiko paramiko是用python语言写的一个模块,遵循SSH2协议,支持以加密和认证的方式,进行远程服务器的连接。 使用paramiko可以很好的解决以下问题: 需要使用windows客户端, 远程连接到Linux服务器,查看上面的日志状态,批量配置远程服务器,文件上传,文件下载等 "paramiko" is a combination of the esperanto words for "paranoid" and "friend".  it's a module for python 2.5+ that implements the SSH2 protocol for secure (encrypted and authenticated) connections to remote machines. unlike SSL (aka TLS), SSH2 protocol does not require hierarchical certificates signed by a powerful central authority. you may know SSH2 as the protocol that replaced telnet and rsh for secure access to remote shells, but the protocol also includes the ability to open arbitrary channels to remote services across the encrypted tunnel (this is how sftp works, for example). it is written entirely in python (no C or platform-dependent code) and is released under the GNU LGPL (lesser GPL). the package and its API is fairly well documented in the "doc/" folder that should have come with this archive. Requirements ------------  - python 2.5 or better <http://www.python.org/>  - pycrypto 2.1 or better <https://www.dlitz.net/software/pycrypto/> If you have setuptools, you can build and install paramiko and all its dependencies with this command (as root)::    easy_install ./ Portability ----------- i code and test this library on Linux and MacOS X. for that reason, i'm pretty sure that it works for all posix platforms, including MacOS. it should also work on Windows, though i don't test it as frequently there. if you run into Windows problems, send me a patch: portability is important to me. some python distributions don't include the utf-8 string encodings, for reasons of space (misdirected as that is). if your distribution is missing encodings, you'll see an error like this::    LookupError: no codec search functions registered: can't find encoding this means you need to copy string encodings over from a working system. (it probably only happens on embedded systems, not normal python installs.) Valeriy Pogrebitskiy says th
