To enable the connection to Informix on Linux, we must perform the following steps:
Prerequisites
Step 1 - Add the i386 architecture and install the packages below :
| UBUNTU\DEBIAN | CENTOS\RHEL |
| - sudo dpkg —add-architecture i386 - sudo apt-get update - sudo apt-get install libaio1:i386 - sudo apt-get install libncurses5:i386 - sudo apt-get install alien - sudo apt-get install gcc-multilib g++-multilib - sudo apt-get install libpam0g:i386 - sudo apt-get install ksh:i386 - sudo apt-get install unixodbc-dev:i386 unixodbc:i386 | - sudo yum update - sudo yum install libaio-devel.i686 - sudo yum install libaio.i686 - sudo yum install glibc.i686 - sudo yum install compat-libstdc++-33.i686 - sudo yum install glibc-devel.i686 - sudo yum install libstdc++.i686 - sudo yum install libstdc++.i686 - sudo yum install pam.i686 - sudo yum install ncurses-devel.i686 - sudo yum install unixODBC.i686 - sudo wget ftp://195.220.108.108/linux/centos/6.7/os/i386/Packages/ksh-20120801-28.el6.i686.rpm - sudo yum install ksh-20120801-28.el6.i686.rpm - sudo yum install nano |
Step 2 - Download Informix Client SDK :
- Client SDK 3.70.UC8.DE
Step 3 - Download PHP extension :
- PHP 56
- PHP 54
Step 4 - Copy the extension to the folder ext from scriptcase :
- sudo cp pdo_informix.so /opt/NetMake/v81/components/apache/ext/
Step 5 - Edit and add on the end of php.ini file the informix extension :
- sudo nano /opt/NetMake/v81/components/apache/conf/php.ini
- extension=pdo_informix.so
Step 6 - Install the Client SDK :
- sudo tar -xf clientsdk.3.70.UC8DE.LINUX.tar
- sudo ./installclientsdk
Required: The Informix client installation directory should be: /opt/IBM/ifx
Step 7 - Edit the php.fcgi file
- sudo nano /opt/NetMake/v81/components/apache/cgi-bin/php.fcgi
Step 8 - Add content down over the line exec $PHPCGI :
INFORMIXDIR="/opt/IBM/ifx/"
INFORMIXSQLHOSTS="/opt/IBM/ifx/etc/sqlhosts"
INFORMIXSERVER="demo_on"
ODBCINI="/opt/IBM/ifx/etc/odbc.ini"
LD_LIBRARY_PATH="/opt/IBM/ifx/lib:/opt/IBM/ifx/lib/esql:/opt/IBM/ifx/lib/cli:/opt/IBM/ifx/lib/c++:/opt/IBM/ifx/lib/client:/opt/IBM/ifx/lib/dmi"
CLIENT_LOCALE="en_US.utf8"
DB_LOCALE="en_US.819"
export INFORMIXDIR
export INFORMIXSQLHOSTS
export INFORMIXSERVER
export ODBCINI
export LD_LIBRARY_PATH
export CLIENT_LOCALE
export DB_LOCALE
Step 9 - Restart apache :
- sudo /etc/init.d/apachesc81 restart
