What is OCI8?

OCI8 is the PHP extension for connecting to Oracle Database. OCI8 is open source and included with PHP. The name is derived from Oracle’s C “call interface” API first introduced in version 8 of Oracle Database. OCI8 links with Oracle client libraries, such as Oracle Instant Client.

Installing Oracle Instant Client And SDK

Before installing OCI8 on your CentOS or RHEL Linux, you need to download and install Oracle Instant client and Oracle Install SDK packages.

To download Oracle Instant client packages, you can go to oracle download page to get it with the following command:

$ wget http://download.oracle.com/otn/linux/instantclient/11204/oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm

$ wget http://download.oracle.com/otn/linux/instantclient/11204/oracle-instantclient11.2-sqlplus-11.2.0.4.0-1.x86_64.rpm

$ wget http://download.oracle.com/otn/linux/instantclient/11204/oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64.rpm

Note:
Instant Client Package – Basic: All files required to run OCI, OCCI, and JDBC-OCI applications
Instant Client Package – SQL*Plus: Additional libraries and executable for running SQL*Plus with Instant Client
Instant Client Package – SDK: Additional header files and an example makefile for developing Oracle applications with Instant Client

Then you can install those downloaded packages with the following command:

$ yum install oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64.rpm oracle-instantclient11.2-sqlplus-11.2.0.4.0-1.x86_64.rpm

Outputs:

[root@devops ~]# yum install oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64.rpm oracle-instantclient11.2-sqlplus-11.2.0.4.0-1.x86_64.rpm

Installing Additional Packages

You need to install some additional packages, such as: gcc, systemtap-sdt-devel, openssl-devel. And upgrade autoconf from the default version to 2.69 or high version. Do the following steps:

#1 install gcc, systemtap-sdt-devel and openssl-devel packages with yum install command, type:

$ yum install gcc systemtap-sdt-devel openssl-devel

Outputs:

[root@devops ~]# yum install gcc

Run it without parameters to see the available actions, try 'pear list'
to see what packages are installed, or 'pear help' for help.

Thanks for using go-pear!

Checking If PEAR Works

After installed PEAR package, you can check the installed version of PEAR on your system to verify if the PEAR package is installed successfully, type:

$ pear version

Outputs:

[root@devops ~]# pear version
PEAR Version: 1.10.9
PHP Version: 7.3.2
Zend Engine Version: 3.3.2

Installing OCI8 with PEAR

Before intalling OCI with PEAR package manager, you need to export one variable PHP_DTRACE on your system with the following command:

$ export PHP_DTRACT=yes

Then you can start to install OCI8 package with the pecl install command, type:

$ pecl install oci8

Outputs:

[root@devops ~]# pecl install oci8-2.2.0

Libraries have been installed in:
/tmp/pear/install/pear-build-root5QR1tG/oci8-2.2.0/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

Installing '/usr/lib64/php/modules/oci8.so'
install ok: channel://pecl.php.net/oci8-2.2.0
configuration option "php_ini" is not set to php.ini location
You should add "extension=oci8.so" to php.ini

After installed OCI8 on your system, pecl will automatically load the extension in your php.ini, so you need to add “extension=oci8.so” to /etc/php.ini.
