PHP agent not connecting to the controller

[destiya]

I'm starting trial for APM product.

I try to install PHP agent on ubuntu server with nginx web server.

First, I tried to use the wizards step. Install steps not throwing an error, but it didn't connect to the controller.

Then, I used https://docs.appdynamics.com/display/PRO43/Install+the+PHP+Agent to install agent manually.

Again, it didn't throw any error, but it didn't connect to the controller.

At this step, I checked the logs, and it output something like this : 

2017-12-11 09:15:01.094 UTC INFO 31304 [agent.AgentKernel] starting up agent kernel [4.3.7.0GA.13218.574dfc04d2aa143c9a690628bc2$

I tried to resolve it using steps described here : https://docs.appdynamics.com/display/PRO43/Resolve+PHP+Agent+Installation+Issues

But when I run "php -i | less", I didn't see any appdynamic block within it.

I have checked that there is appdynamics_agent.ini in the same directory with php.ini

Is there any solution about it?

Thank you in advance

Hi Piyush,

Thank you for your help.

It seems I need to place the configuration within the additional configuration directory to make it work.

Next, how can I run the agent for both PHP FPM and CLI.

Do I need to install it twice and place the configuration in both FPM and CLI?

Because they have different configuration folder.

THank you again.

 Hi Destiya,

One single agent installation can serve all of these modes but it needs to switch to the manual start of JAVA proxy process and some more tweaking in the configs. For simplicity and easy access to agent files, I suggest going ahead with multiple installation directories using -i and -e parameters mentioned at https://docs.appdynamics.com/display/PRO43/Install+the+PHP+Agent+by+Shell+Script
