Download the Oracle Instant Client and SDK from Oracle website. (Need to login in Oracle page)
http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html
Files: instantclient-basic-linux.x64-12.2.0.1.0.zip
and instantclient-sdk-linux.x64-12.2.0.1.0.zip
.
Create a new folder to store Oracle Instant Client zip files on your server.
Upload the Instant Clients files inside this folder.
mkdir /opt/oracle
Now we need to extract the files.
cd /opt/oracle
unzip instantclient-basic-linux.x64-12.2.0.1.0.zip
unzip instantclient-sdk-linux.x64-12.2.0.1.0.zip
Next, we need to create a symlink to Instant Client files.
ln -s /opt/oracle/instantclient_12_2/libclntsh.so.12.1 /opt/oracle/instantclient_12_2/libclntsh.so
ln -s /opt/oracle/instantclient_12_2/libocci.so.12.1 /opt/oracle/instantclient_12_2/libocci.so
Add the folder to our ldconfig
.
echo /opt/oracle/instantclient_12_2 > /etc/ld.so.conf.d/oracle-instantclient
Update the Dynamic Linker Run-Time Bindings
ldconfig
Done. Now we can proceed to the next part.
To install the OCI8 extension, we need to install some additional package on our server.
Run these command:
apt-get install php-dev php-pear build-essential libaio1
Once installed, we need to get the OCI8 file. But, before that we need to update PECL channel.
pecl channel-update pecl.php.net
Then.
pecl install oci8
When you are prompted for the Instant Client location, enter the following:
instantclient,/opt/oracle/instantclient_12_2
We need to tell PHP to load the OCI8 extension.
echo "extension =oci8.so" >> /etc/php/7.2/fpm/php.ini
echo "extension =oci8.so" >> /etc/php/7.2/cli/php.ini
echo "extension =oci8.so" >> /etc/php/7.2/apache2/php.ini
We also need to add on apache those environment variables.
echo "export LD_LIBRARY_PATH=/opt/oracle/instantclient_12_2" >> /etc/apache2/envvars
echo "export ORACLE_HOME=/opt/oracle/instantclient_12_2" >> /etc/apache2/envvars
echo "LD_LIBRARY_PATH=/opt/oracle/instantclient_12_2:$LD_LIBRARY_PATH" >> /etc/environment
Refresh the server. If you are accessing through SSH, then
exit
or
sudo shutdown -r now
Check if the extension is enabled.
php -m | grep 'oci8'
If returns oci8
, its works!
Restart the PHP-FPM
service php7.2-fpm restart
Now you can connect to Oracle DBMS from your PHP applications.
Thanks for the rundown. Works except for one step point.
After following all the steps,
php -m
gave the following warning:PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/20170718/oci8.so' (tried: /usr/lib/php/20170718/oci8.so (libmql1.so: cannot open shared object file: No such file or directory), /usr/lib/php/20170718//usr/lib/php/20170718/oci8.so.so (/usr/lib/php/20170718//usr/lib/php/20170718/oci8.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0
Which means that
libmql1.so
could not be found. The solution:Rename the file
/etc/ld.so.conf.d/oracle-instantclient
to/etc/ld.so.conf.d/oracle-instantclient.conf
. I noticed that/etc/ld.so.conf
loads files looking like/etc/ld.so.conf.d/*.conf
, thus the rename.Check that your system can find/resolve all the shared libraries with:
ldd /usr/lib/php/20170718/oci8.so
