## Installation

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 pecl installer for PECL/ssh2: pecl 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: pecl install ssh2-beta

Tip

# Compiling PECL/ssh2 without using the PECL command

Rather than using pecl install ssh2 to automatically download and install PECL/ssh2, you may download the tarball from » PECL. From the root of the unpacked tarball, run: phpize && ./configure --with-ssh2 && make to generate ssh2.so. Once built, continue the installation from step 4 above.

Information for installing this PECL extension may be found in the manual chapter titled Installation of PECL extensions. Additional information such as new releases, downloads, source files, maintainer information, and a CHANGELOG, can be located here: » http://pecl.php.net/package/ssh2.

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