Possible to set up New Relic's PHP agent?

Step 1

First, install a "PHP" or reuse an existing application from the control panel.

Then, mount it to a website record. I'll use "/" for my URL Path to mount it at the root of the domain, but you could mount it at a different URL Path as well; for example "/foo".

Step 2

Next, open an SSH session. Enter the following commands to install New Relic and move the files into place.

mkdir $HOME/pecl_install
cd $HOME/pecl_install
wget https://download.newrelic.com/php_agent/release/newrelic-php5-4.4.5.35-linux.tar.gz
tar xzvf newrelic-php5-4.4.5.35-linux.tar.gz
cd newrelic-php5-4.4.5.35-linux
cp daemon/newrelic-daemon.x64 $HOME/bin/newrelic-daemon
cp scripts/newrelic.cfg.template $HOME/newrelic.cfg
cp scripts/newrelic.ini.template $HOME/webapps/<your php application>/newrelic.ini

# PHP 5.2
mkdir $HOME/php52-exts
cp agent/x64/newrelic-20060613.so $HOME/php54-exts/newrelic.so
echo "extension_dir = $HOME/php52-exts" >> $HOME/webapps/<your php application>/php.ini

# PHP 5.3
mkdir $HOME/php53-exts
cp agent/x64/newrelic-20090626.so $HOME/php54-exts/newrelic.so
echo "extension_dir = $HOME/php53-exts" >> $HOME/webapps/<your php application>/php.ini

# PHP 5.4
mkdir $HOME/php54-exts
cp agent/x64/newrelic-20100525.so $HOME/php54-exts/newrelic.so
echo "extension_dir = $HOME/php54-exts" >> $HOME/webapps/<your php application>/php.ini

# PHP 5.5
mkdir ~/php55-exts
cp agent/x64/newrelic-20121212.so ~/php55-exts/newrelic.so
echo "extension_dir = $HOME/php55-exts" >> ~/webapps/<your php application>/php.ini

# User for all version of PHP
echo "extension = newrelic.so" >> $HOME/webapps/<your php application>/php.ini

Step 3

Edit $HOME/newrelic.cfg, change this setting to a path in your account:

port="/home/<your username>/newrelic.sock"

Step 4

Edit $HOME/webapps/<your php application>/newrelic.ini, change these settings to the paths of your account or to match your new relic settings:

newrelic.license = "<your New Relic License>"
newrelic.logfile = "/home/<your username>/logs/user/php_agent.log"
newrelic.appname = "PHP Application"
newrelic.daemon.logfile = "/home/<your username>/logs/user/newrelic-daemon.log"
newrelic.daemon.port = "/home/<your username>/newrelic.sock"
newrelic.daemon.location = "/home/<your username>/bin/newrelic-daemon"

Step 5

Start the daemon:

$HOME/bin/newrelic-daemon -d info -c $HOME/newrelic.cfg -l $HOME/logs/user/newrelic.log

Step 6

Go to your New Relic Dashboard and add a new application.

Step 7

In the application you created in step one add index.php or rename index.html to index.php. Add some php code to the index.php, for example:

<?php phpinfo(); ?>

Step 8

Visit the domain used in step 1 and check the New Relic dashboard for updates.

** Note this only works on CentOS 6 machines. If you are on a CentOS 5 machine you will need to migrate to a CentOS 6 to use New Relic with PHP.

Thanks for sharing these easy steps. the newrelic daemon is running but doesn't show up in the NR dashboard. I have two questions:

Is it necessary to create a website including working domain? (is this safe?)

Is there a way how I can test any think is fine? The log file doesn't show anything strange:

2014-02-04 14:52:50.069 (19970/main) info: New Relic 4.4 (release build 35 - "ozraptor" - "01be49bf5a052f43a56d8f18632a5dccc5dfed07") [workers=1 listen='/home/myusername/newrelic.sock' pid=19970 ppid=19969 uid=527 euid=527 gid=527 egid=527 backtrace=no os='Linux' rel='2.6.32-358.23.2.el6.x86_64' mach='x86_64' ver='#1 SMP Wed Oct 16 18' node='webXXX.webfaction.com' startup=init] 2014-02-04 14:52:50.069 (19970/main) info: RPM config: proto='https' collector='collector.newrelic.com' proxy='none' certfile='/etc/pki/tls/certs/ca-bundle.crt' certdir='/etc/ssl/certs'

Is it normal that the sockfile has zero bytes?
