Directadmin – Proxy Error: DNS lookup failure for php-fpm56 …

If you changed php handler for your Directadmin installation to php-fpm, rewrite all configs and then get error like this:

Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /index.php.
Reason: DNS lookup failure for: php-fpm56.domainname

It is almost certainly that apache templates that are used for generating user http configuration files are wrong. Probably you have custom templates.

Go to /usr/local/directadmin/data/templates/custom and check if there are files like files virtual_host2.conf … . If they are, just rename custom directory to something new:

[root@lol ~]# cd /usr/local/directadmin/data/templates/
[root@lol templates]# mv custom custom-bak

Directadmin will then use default templates when creating new Apache configs. Rewrite your apache config files:

[root@lol ~]#  cd /usr/local/directadmin/custombuild
[root@lol custombuild]# ./build rewrite_confs

It should solve the problem. Also, make sure that php-fpm for all php versions are working.

Install PHP extension on Directadmin – fast and easy way (without custombuild)

Directadmin is pretty good, lightweight, control panel for providing web hosting service or to host your own websites/projects, managing mail … Through the years, I recompiled PHP with custombuild countless times. Problem is, that every time that you want to install some new PHP extension – exif, in this example – you’ll have to rebuild whole PHP with Directadmin’s custombuild also. That can be very annoying and time-consuming. Expesialy when things go wrong. So, there is simple way on how to quickly install PHP extensions without using custombuild. I used this way many times. In this case, installation was done on CentOS 7.2 server with Directadmin and PHP version 5.6.23.

I hope this was helpful to you in any way.

Directadmin and wrong JPEG library version – FreeBSD

I came across this error a few times on DirectAdmin installations. I first noticed this error when I installed Nextgen Gallery plugin on some WordPress installation. When I tried to upload some pictures, php should resize them and create thumbnails, but instead of thumbnails I’ll get error about JPEG library (checked in error log). Below is procedure on how to fix that error. At least it worked for me. This Directaadmin was installed on FreeBSD 9.1.

  • Login as root
  • Update ports
[root@lala ~]# portsnap fetch update
  • Delete currently installed JPEG library
[root@lala ~]# pkg_info | grep jpeg
[root@lala ~]# pkg_delete jpeg
  • Install jpeg library with custombuild
  • Edit your configuration script for php in custombuild. Add or edit values as bellow. Notice that path is not /usr/local/lib anymore.
–with-gd \
–with-jpeg-dir=/usr/local \
  • Rebuild PHP with custombuild
[root@lala ~]# cd /usr/local/directadmin/custombuild
[root@lala /usr/local/directadmin/custombuild]# ./build php n
  • When build is complete, restart Apache and try it again. It should work.
[root@lala ~]# /usr/local/etc/rc.d/httpd restart
