Php支持ssl，ssh扩展：

准备：可以成功解析php

1.curl的安装

[root@localhost~]# cd /usr/local/src/

[root@localhost~]# wget https://curl.haxx.se/download/curl-7.47.1.tar.gz

[root@localhost~]# tar zxvf curl-7.47.1.tar.gz

[root@localhost~]# cd curl-7.47.1

[root@localhost~]# ./configure --with-ssl --with-libssh2

出现：configure: error: libSSH2 libs and/or directories were not found where specified!

[root@localhost ]# yum install libssh2 libssh2-devel

[root@localhost~]# ./configure --with-ssl --with-libssh2

curl version:     7.47.1

Host setup:       x86_64-pc-linux-gnu

Install prefix:   /usr/local

Compiler:         gcc

SSL support:      enabled (OpenSSL)

SSH support:      enabled (libSSH2)

至此ssl，ssh已经使能了。

lamp的php安装：

[root@localhost~]# cd php-5.1.14

[root@localhost~]# ./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-mbstring --enable-sockets --enable-exif --disable-ipv6 --with-curl --with-openssl --with-zlib-dir --enable-ftp

[root@localhost~]# make

如果出现 [sapi/cli/php]错误

执行：

[root@localhost~]# make ZEND_EXTRA_LIBS='-liconv'

[root@localhost~]# ln -s /usr/local/lib/libiconv.so.2 /usr/lib64/

[root@localhost~]# make install

[root@localhost~]# cp php.ini-production /usr/local/php/etc/php.ini

[root@localhost~]# vim /usr/local/php/etc/pnp.ini

去掉这行的注解并改成data.timezone = Asia/shanghai

安装libssh2库与ssh2

[root@localhost~]# cd /usr/local/src/

[root@localhost~]# wget http://www.libssh2.org/download/

[root@localhost~]# wget http://pecl.php.net/package/ssh2

[root@localhost~]# tar -zxvf libssh2-1.4.2.tar.gz

[root@localhost~]# cd libssh2-1.4.2

[root@localhost~]# ./configure --prefix=/usr/local/libssh2

[root@localhost~]# make && make install

[root@localhost~]# tar -zxvf ssh2-0.12.tgz

[root@localhost~]# cd ssh2-0.12

[root@localhost~]#./configure --prefix=/usr/local/ssh2 --with-ssh2=/usr/local/libssh2 --with-php-config=/usr/local/php/bin/php-config

[root@localhost~]#make && make install

[root@localhost~]# cp modules/ssh2.so /usr/lib64/php/modules/

[root@localhost~]# vim /usr/local/php/etc/php.ini

添加一行：extension=ssh2.so

[root@localhost~]# /usr/local/php/sbin/php-fpm -i|grep ssh2

出现：下图内容则配置成功

[root@localhost~]# vim /data/www/3.php

<?php

$user="root";

$pass="li";

$connection=ssh2_connect('192.168.1.111',22);

ssh2_auth_password($connection,$user,$pass);

$cmd="ls";

$ret=ssh2_exec($connection,$cmd);

stream_set_blocking($ret, true);

echo (stream_get_contents($ret));

?>

[root@localhost~]# /usr/local/apache2/bin/apachectl restart

访问 http://192.168.1.106/3.php

即ssh执行成功！！！

可能出现的问题：

php版本与ssh扩展模块版本不匹配，需要更新版本。
