SQLServer CentOS 7

There are two different drivers you can use to connect to Microsoft SQL. We highly recommend the sqlsrv driver over dblib/freetds. However dblib/freetds is still supported.

SQLSRV

Note: These instructions were adapted from the official Microsoft PHP SQLSRV repo on Github[1]. Please consult this repo for additional information about this driver and its implementation options.

1. Install the ODBC 13 Driver
   • <source lang="bash">$ sudo sh -c 'curl https://packages.microsoft.com/config/rhel/7/prod.repo > /etc/yum.repos.d/mssql-release.repo'</source>
   • If the unixodbc-utf16 packages are already installed
     • <source lang="bash">$ sudo yum remove unixODBC-utf16 unixODBC-utf16-devel</source>
   • <source lang="bash">$ sudo ACCEPT_EULA=Y yum install msodbcsql unixODBC-devel</source>
2. Install tools used for PECL
   • <source lang="bash">$ sudo yum install php71w-devel php71w-pear</source>
   • <source lang="bash">$ sudo yum groupinstall 'Development Tools'</source>
3. Install sqlsrv and pdo_sqlsr using PECL
   • sqlsrv on PECL is has been released from development to stable. As of the writing of these instructions, the latest verison 4.3.0.
     • <source lang="bash">$ sudo pecl install sqlsrv</source>
     • <source lang="bash">$ sudo pecl install pdo_sqlsrv</source>
4. Create the ini files
   • <source lang="bash">$ sudo sh -c 'echo "extension=sqlsrv.so" > /etc/php.d/sqlsrv.ini'</source>
   • <source lang="bash">$ sudo sh -c 'echo "extension=pdo_sqlsrv.so" > /etc/php.d/pdo_sqlsrv.ini'</source>
5. Restart PHP-FPM or Apache (whichever solution you're using.)

DBLIB/FreeTDS

1. Install the module using Yum
   • <source lang="bash">$ sudo yum install php71w-mssql</source>
2. Restart PHP-FPM or Apache (whichever solution you're using.)
