SSH2 扩展的安装

PHP 的 SSH2 扩展

系统环境

• CentOS 6.8
• libssh2-1.8.0
• php-devel
• ssh2-0.13

前提环境安装好 LNMP 或 LAMP

• 安装 OpenSSL

  $ yum install -y openssl openssl-devel

• 编译安装 libssh2

  $ cd /usr/local/src
  $ wget https://www.libssh2.org/download/libssh2-1.8.0.tar.gz
  $ tar xvf libssh2-1.8.0.tar.gz
  $ cd libssh2-1.8.0
  $ ./configure --prefix=/usr/local/libssh2
  $ make && make install

• 编译安装 ssh2

  $ cd /usr/local/src/
  $ wget http://pecl.php.net/get/ssh2-0.13.tgz
  $ tar xvf ssh2-0.13.tgz 
  $ cd ssh2-0.13
  $ phpize                ##没有的话yum install php-devel ubuntu apt-get install php7.0-dev
  $ ./configure --prefix=/usr/local/ssh2 --with-ssh2=/usr/local/libssh2
  $ make  

• 拷贝 ssh2.so

  在当前目录/modules下会生成一个
  $ cp modules/ssh2.so /usr/lib64/php/modules/

• 修改 php 配置文件

  $ echo "extension=ssh2.so" >> /etc/php.ini

• 查看是否成功

  $ php -m | grep ssh2
  ssh2
