下载地址

wget http://www.libssh2.org/download/libssh2-1.4.2.tar.gz
wget http://pecl.PHP.net/get/ssh2-0.12.tgz

先安装 libssh2 在安装 SS2

# tar -zxvf libssh2-1.4.2.tar.gz
# cd libssh2-1.4.2
# ./configure --prefix=/usr/local/libssh2
# make && make install

以上为安装libssh2，这里需要记住libssh2的安装目录，因为在安装ssh2的时候还会用到。

# tar -zxvf ssh2-0.12.tgz
# cd ssh2-0.12
# PHPize
# ./configure --prefix=/usr/local/ssh2 --with-ssh2=/usr/local/libssh2
# make

SSH安装

# tar -zxvf ssh2-0.12.tgz
# cd ssh2-0.12
# PHPize
# ./configure --prefix=/usr/local/ssh2 --with-ssh2=/usr/local/libssh2 --with-PHP-config=/usr/local/PHP/bin/PHP-config
# make && make install

安装完成之后SSH2扩展在 /usr/local/PHP/lib/PHP/extensions/no-debug-non-zts-20121212/ 目录中
修改PHP.ini文件加入

extension=ssh2.so

啊哈哈加入扩展成功

<?PHP
$user="root";//远程用户名
$pass="123456";//远程密码
$connection=ssh2_connect('192.168.1.46',22);
ssh2_auth_password($connection,$user,$pass);
$cmd="psaux";//命令 $ret=ssh2_exec($connection,$cmd); stream_set_blocking($ret,true); echo (stream_get_contents($ret));//print_r(PHPinfo());?>
