PHP Startup: Unable to load dynamic library (NEW RELIC)
I am running Ubuntu 12.04 with Nginx and the latest PHP. The story goes like this: I tried to install the new relic PHP agent per the instructions for ubuntu:
wget -O - http://download.newrelic.com/548C16BF.gpg | sudo apt-key add -
sudo sh -c 'echo "deb http://apt.newrelic.com/debian/ newrelic non-free"
> /etc/apt /sources.list.d/newrelic.list'
sudo apt-get update
sudo apt-get install newrelic-php5
sudo newrelic-install install
And it doesn't work. After everything the PHP agent simply can't start. I even whipped up a quick phpinfo.php page to see if the newrelic module was listed and it's not. So then I googled "New relic .deb" and came across this page: https://docs.newrelic.com/docs/server/server-monitor-installation-ubuntu-and-debian and followed the instructions. The install all goes through but the agent also doesn't start. I like to keep my servers clean so I decided "OK, since it doesn't work, until new relic support gets back to me and I can start from fresh I will remove the new relic stuff that was installed". So once again I followed the instructions on that link. The install seemed to work normally. However, if I execute the command "PHP" I get the following error:
root@MYHOSTNAME:/home# php
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20121212
/newrelic.so' - /usr/lib/php5/20121212/newrelic.so: cannot open shared object file:
No such file or directory in Unknown on line 0
I made sure there is no reference to newrelic in my /etc/php/fpm/php.ini file and double checked to see if there was anything in that folder. Nothing.
So my question is: how do I get rid of the error? How do I make PHP stop trying to load that newrelic.so module? Is there any reference to it somewhere that I might be missing?
Answer
Ok, I found the answer. I can't describe how grateful I am to @mike in the following post: Error In PHP5 ..Unable to load dynamic library. I ran $ grep -Hrv ";" /etc/php5 | grep -i "extension=" and it returned a large list of files and one of them was newrelic.ini in /etc/php5/cli/conf.d/ which to be honest with you I wasn't even aware was a php directory. So I ran sudo rm -rf /etc/php5/cli/conf.d/newrelic.ini and restarted nginx and php5-fpm, and problem solved :)
Thanks @WayneWhitty for the suggestions! I am also going to let newrelic know that they should fix that on their uninstall script.
