====== Enabling the php oci8  ======

===== APT install =====
  - php 관련 패키지를 설치한다. <code>
# apt-get install build-essential libaio1 
</code>
  - php 패키지를 설치 (ubuntu 18.04 ) <code>
# apt-get install libapache2-mod-php7.2 php7.2 php7.2-dev apache2
</code> \\ ubuntu 16.04 일 경우에는 아래의 명령어로 설치 <code>
# apt-get install libapache2-mod-php7.0 php7.0 php7.0-dev apache2
</code>

===== Oracle Installed =====

==== Oracle Server ====

^ ORACLE_BASE | /usr/local/instantclient_11_2 |
^ ORACLE_HOME | /usr/local/instantclient_11_2 | 
^ LD_LIBRARY_PATH | /usr/local/instantclient_11_2 |

==== Oracle Instant ====
  - [[dbms:oracle:admin:instantclient | Oracle Instant 설치방법 ]]
  - bash 설정 <code>
# vi /etc/bash_completion.d/oracle
export ORACLE_BASE="/usr/local/instantclient_11_2"
export ORACLE_HOME="/usr/local/instantclient_11_2"
export LD_LIBRARY_PATH="/usr/local/instantclient_11_2"
</code>
  - /etc/environment <code>
...
LD_LIBRARY_PATH=/usr/local/instantclient_11_2:$LD_LIBRARY_PATH
</code>
  - <code>
echo /usr/local/instantclient_11_2 > /etc/ld.so.conf.d/oracle-instantclient.conf
</code>
===== OCI8 Install =====

  - http://pecl.php.net/package/oci8 에서 최신버젼을 다운로드 받는다. <code>
$ wget http://pecl.php.net/get/oci8-2.1.8.tgz
</code>
  - 압축을 해제한다. <code>
$ tar xvfz oci8-2.1.8.tgz
</code>
  - 소스경로로 이동한다. <code>
$ cd oci8-2.1.8/
</code>
  - PHP 확장모듈을 위한 빌드환경을 만들기 위해 phpize 를 실행한다. <code>
$ phpize
</code>
  - libclntsh.so 경로를 확인한다. <code>
# oracle server 설정
$ ls $ORACLE_HOME/lib/libclntsh.so
/u01/app/oracle/product/10.2.0/lib/libclntsh.so
or
# oracle instant client 설정
$ ls $ORACLE_HOME/libclntsh.so
/usr/local/instantclient_11_2/libclntsh.so
</code> 링크가 제대로 존재하는지 확인 <code>
$ cd $ORACLE_HOME
$ ln -s /usr/local/instantclient_11_2/libocci.so.11.1 libocci.so
$ ln -s /usr/local/instantclient_11_2/libclntsh.so.11.1 libclntsh.so
</code>
  - 환경설정을 맞춰서 컴파일을 한다. \\ --with-oci8 에 상황에 맞게 shared 와 instantclient 를 붙여준다. <code>
$ ./configure --with-oci8=$ORACLE_HOME (default)
$ ./configure --with-oci8=instantclient,$ORACLE_HOME
$ ./configure --with-oci8=shared,instantclient,$ORACLE_HOME
</code> --with-oci8=instantclient,$ORACLE_HOME 으로 진행
  - make <code>
$ make
</code>
  - make install 를 실행한다. \\ root가 아닐 경우 퍼미션 에러가 날 수 있다, 이때에는 sudo 를 같이 써준다. <code>
$ make install
$ sudo make install

Libraries have been installed in:
   /home/starlits/src/opensources/oci8-2.0.8/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.

</code>
  - /etc/php/7.2/apache2/php.ini 에서 oci8을 확인한다. <code>
# vi /etc/php/7.2/apache2/php.ini
...
;extension=oci8_12c  ; Use with Oracle Database 12c Instant Client
;extension=odbc
;extension=openssl
;extension=pdo_firebird
;extension=pdo_mysql
;extension=pdo_oci
;extension=pdo_odbc
;extension=pdo_pgsql
;extension=pdo_sqlite
;extension=pgsql
;extension=shmop
extension=oci8
...
</code>
  - /etc/php/7.2/cli/php.ini 에서 oci8을 확인한다. \\ cli 설정시 php -m 으로 설치모듈을 확인할 수 있다. <code>
# vi /etc/php/7.2/cli/php.ini
...
extension=oci8
..
</code> <code>
# php -m | grep oci8
oci8
</code>
  - apache2 재시작 
  - phpinfo 로 확인
