Enabling/installing GD extension? --without-gd

问题:

How does one enable (or perhaps I need to install) GD when my phpinfo() output in "Configure Command" says; --without-gd ?

I also have nothing in my phpinfo() output "Core" that lists "gd"

PHP Version 5.2.4 on AWS.

回答1:

if you are on a Debian based server (such as Ubuntu) you can run the following command:

apt-get install php5-gd

Then once it is complete run:

/etc/init.d/apache2 restart

This will restart your server and enable GD in PHP.

If you are on another type of system you will need to use something else (like yum install) or compile directly into PHP.

For PHP7.0 use (php7.1-gd, php7.2-gd and php7.3-gd are also available):

sudo apt-get install php7.0-gd

and than restart your webserver.

回答3:

Check if in your php.ini file has the following line:

;extension=php_gd2.dll

if exists, change it to

extension=php_gd2.dll

and restart apache

(it works on MAC)

回答4:

In my case (php 5.6, Ubuntu 14.04) the following command worked for me:

sudo apt-get install php5.6-gd

According to php version we need to change the php5.x-gd

回答5:

All previous answers are correct but were not sufficient for me on ArchLinux. I also needed to edit /etc/php/php.ini and to uncomment :

;extension=gd.so 

The initial ; on the line needs to be removed. After restarting Nginx via systemctl restart nginx, I was good to go.

回答6:

For php7.1 do:

sudo apt-get install php7.1-gd

and restart webserver. For apache do

sudo service apache2 restart

回答7:

In CentOS (but the same may apply to other distros too) if you install the php7x-gd module followed by Apache restart and still the php -i does not show the GD Support => enabled it might mean that the php.ini was not automatically configured to support this extension.

All you have to to is either to edit the /etc/php/php.ini or to create a /etc/php.d/gd.ini file with the following content:

[gd]
extension=/path/to/gd.so # use the gd.so absolute path here

If You're using php5.6 and Ubuntu 18.04 Then run these two commands in your terminal your errors will be solved definitely.

sudo apt-get install php5.6-gd

then restart your apache server by this command.

 sudo service apache2 restart
