#环境CentOS7.3
#第一、安装支持库文件
yum install make gcc-c++ glibc-devel zlib-devel openssl-devel libssh2-devel php-devel
##编译安装libssh2
wget http://www.libssh2.org/download/libssh2-1.8.0.tar.gz
tar zxvf libssh2-1.8.0.tar.gz
cd libssh2-1.8.0
./configure&&make&&make install
#第二、安装SSH2扩展 (php7必须下载ssh2-1.0.tgz)
wget http://pecl.php.net/get/ssh2-1.0.tgz
tar -xzf ssh2-1.0.tgz
cd ssh2-1.0
phpize && ./configure --with-ssh2 && make && make install
#第三、修改ssh2.ini
touch /etc/php.d/ssh2.ini
echo extension=ssh2.so > /etc/php.d/ssh2.ini
#第四、检查SSH2是否安装成功
php -m | grep ssh2
php -i|grep ssh2
#通过以下php代码测试：
<?php
$connection = ssh2_connect("192.168.209.250",22);
if (ssh2_auth_password($connection,"您的FTP用户名","FTP密码"))
{
echo "Authentication Successful! ";
}
else
{
die("Authentication Failed...");
}
?>
