Hello, I'm trying to install the oracle DB extension on this RHEL7 system but I can't get it to work. The server says on startup: $ grep oci /var/log/httpd/error_log PHP Warning: PHP Startup: Unable to load dynamic library 'oci8' (tried: /usr/lib64/php/modules/oci8 (/usr/lib64/php/modules/oci8: cannot open shared object file: No such file or directory), /usr/lib64/php/modules/oci8.so (libclntsh.so.21.1: cannot open shared object file: No such file or directory)) in Unknown on line 0 But the file is right there: $ ls -l /usr/lib64/php/modules/oci8.so -rwxr-xr-x. 1 root root 185832 May 4 14:13 /usr/lib64/php/modules/oci8.so phpinfo.php lists the OCI8 modules with their authors. What am I missing? -- robert

libclntsh.so.21.1 shared library file is missing. The OCI8 module needs the
libclntsh.so.21.1 shared library to also be installed. Yes the error message
is a little confusing.

Which is to be expected. Then it tries /usr/lib64/php/modules/oci8.so which it does find but cannot open because its dependency, libclntsh.so.21.1, is not found. What does 'ldd /usr/lib64/php/modules/oci8.so' show? Do you have libclntsh.so.21.1 installed somewhere on your system? If not you'll need to install it. If it is installed, then you'll need to set the library path to point to it, so that it can be found when needed.

If it is installed in a "standard place", ldconfig will take care of it.

The error showed that either it was not installed at all or it was not in a "standard place".

What am I missing? You miss libclntsh.so.21.1, not oci8.so.

Found and installed the appropriate rpm from Oracle, fixed the conf file in /etc/ld.conf.d/, ran ldconfig, restarted Apache, and voila. -- robert
