简介

Bindings to the » libssh2 library which provide access to resources (shell, remote exec, tunneling, file transfer) on a remote machine using a secure cryptographic transport.

安装

Windows binaries may be found at » http://snaps.php.net/. To install, download php_ssh2.dll to the folder specified by your php.ini file's extension_dir directive. Enable it by adding extension=php_ssh2.dll to your php.ini and restarting your web server.

extension_dir=c:/php5/exts/
extension=php_ssh2.dll

 

Linux, BSD, and other *nix variants can be compiled using the following steps:

• Download and install » OpenSSL. If you install OpenSSL via your distribution's packaging system be sure to install the development libraries as well. This will typically be a package named openssl-dev, openssl_devel, or some variation thereof.
• Download and install » libssh2. Typically this means executing the following command from the libssh2 source tree. ./configure && make all install.
• Run the pear installer for PECL/ssh2: pear install ssh2
• Copy ssh2.so from the directory indicated by the build process to the location specified in your php.ini file under extension_dir.
• Add extension=ssh2.so to your php.ini
• Restart your web server to reload your php.ini settings.

Note: Development Versions There are currently no stable versions of PECL/ssh2, to force installation of the beta version of PECL/ssh2 execute: pear install ssh2-beta

安装此 PECL 扩展库的信息可在手册中标题为 PECL 扩展库安装的一章中找到。 更多信息如新版本，下载，源文件，维护者信息以及更新日志等可以在这里找到： » http://pecl.php.net/package/ssh2.

Note: You will need version 0.4 or greater of the libssh2 library (possibly higher, see release notes).
