Troubleshooting errors while installing PHP agent

Error while loading shared libraries: libcurl.so.4: cannot open shared object file:  No such file or directory

APM Insight PHP agent requires libcurl to be available in the default library directories, like /usr/lib. However, if libcurl is not installed on the system, the agent can use the library in the /opt/zpa/lib directory.

To enable the agent to use the pre-compiled version shipped with PHP Agent, follow the below given steps:

1. Navigate to /opt/zpa/lib and type the command 
  1. 'ln -s libcurl.so.4.4.0 libcurl.so.4'. This will create a symbolic link and zpdp will load properly
2. Restart the zpdp service, via 
cd /opt/zpa/bin && sh run.sh restart 
Or
(on systemd supported servers) service zpdpsvc restart.
