Call to undefined function sftp\ssh2_connect()

centos安装php的ssh2扩展

事先准备需要的

 libssh2 下载  wget https://www.libssh2.org/download/libssh2-1.8.0.tar.gz

ssh2下载 wget  wget http://pecl.php.net/package/ssh2/ssh2-1.1.2.tgz

cd /usr/loca/src
wget https://www.libssh2.org/download/libssh2-1.8.0.tar.gzwget http://pecl.php.net/package/ssh2/ssh2-1.1.2.tgz 

//解压
 tar -zxvf libssh2-1.8.0.tar.gz
 
 cd libssh2-1.8.0
 //编译到libssh2
 ./configure --prefix=/usr/local/libssh2
 
 make && make install
 
 
 
 
 #解压ssh2
 tar -zxvf ssh2-1.1.2.tgz   解压的时候报错看了一下文件类型是XHTML 最后在桌面解压好上传的
 cd ssh2-1.1.2
 phpize 结果报错如下

Can't find PHP headers in /usr/include/php The php-devel package is required for use of this command

直接安装php-dev

yum install php55w-del ;//PHP版本是5.5的

执行phpize

./configure --prefix=/usr/local/ssh2 --with-ssh2=/usr/local/libssh2

结果都是报错，上官网看了一下，原来是ssh2-1.0yi以上版本是PHP7.0

下载0.12版本

cd ssh2-0.12/
phpize
./configure --prefix=/usr/local/ssh2 --with-ssh2=/usr/local/libssh2

make

//复制ssh2.so 到 /usr/lib64/php/modules/
///usr/lib64/php/modules/ php扩展目录
 cp modules/ssh2.so /usr/lib64/php/modules/
 
 vi /etc/php.ini
 添加 extension=ssh2.so
 
 上面就ok了
 查询一下 php -i|grep ssh2
