Install PHP OCI8

oci8.sh

#1. Download the desired Instant Client RPM packages. All installations require the Basic or Basic Lite RPM.

http://download.oracle.com/otn/linux/instantclient/121020/oracle-instantclient12.1-basic-12.1.0.2.0-1.x86_64.rpm
http://download.oracle.com/otn/linux/instantclient/121020/oracle-instantclient12.1-devel-12.1.0.2.0-1.x86_64.rpm

#2. As the root user, install the packages with "rpm". For example:

rpm -ivh oracle-instantclient12.1-basic-12.1.0.2.0-1.x86_64.rpm
rpm -ivh oracle-instantclient12.1-devel-12.1.0.2.0-1.x86_64.rpm

#3. Set the environment variable LD_LIBRARY_PATH to the appropriate directory for the Instant Client version, for example:

export LD_LIBRARY_PATH=/usr/lib/oracle/12.1/client64/lib:$LD_LIBRARY_PATH

#Alternatively, add this path to an ldconfig configuration file if there is no other Oracle software that will be impacted.

#4. To use supplied binaries such as SQL*Plus, update your PATH environment variable, for example:

export PATH=/usr/lib/oracle/12.1/client64/bin:$PATH
