问题
I tried to install the mongodb driver for PHP on Amazon Linux.
While running sudo pecl install mongo, I get the error message:
fatal error: openssl/evp.h: No such file or directory
#include <openssl/evp.h>
^
compilation terminated.
make: *** [io_stream.lo] Error 1
ERROR: `make' failed
PEAR Version: 1.9.5 PHP Version: 5.3.29
I installed gcc which helped me progress further with the install till this error.
The best Guide I was able to find was here: http://jonathanhui.com/install-mongodb-amazon-linux PHP's guide: http://php.net/manual/en/mongo.installation.php
回答1:
evp is high-level cryptographic functions.
Try to install development libraries:
Ubuntu:
sudo apt-get install libssl-dev
CentOS:
yum install openssl-devel
回答2:
The right package to install is not libssl-dev but
sudo apt-get install pkg-config
and now you can execute
sudo pecl install mongodb
Don't forget to add extension=mongodb.so to your php.ini file.
To know which php.ini file is loaded you can create and simple php file on vps
<?php
php_info()
?>
Example directory php.ini in phpinfo()
