Linux 下 PHP 5.2.x 连接 SQL Server 数据库 FreeTDS 配置笔记

　CentOS 5.4 Linux 下的 PHP（FastCGI） 需要连接相关部门的SQL Server 2000数据库，配置了扩展FreeTDS扩展。

　　 1、编译安装FreeTDS

mkdir -p /data0/software/
cd /data0/software/
wget ftp://ftp.ibiblio.org/pub/Linux/ALPHA/freetds/stable/freetds-stable.tgz
tar zxvf freetds-stable.tgz
cd freetds-0.82/
./configure --prefix=/usr/local/webserver/freetds --with-tdsver=8.0 --enable-msdblib
make && make install
cd ../

echo "/usr/local/webserver/freetds/lib/" > /etc/ld.so.conf.d/freetds.conf
ln -s /usr/local/webserver/freetds/lib/libsybdb.so.5.0.0 /usr/local/webserver/freetds/lib/libsybdb.so.4
/sbin/ldconfig

rm -f /usr/local/webserver/freetds/etc/freetds.conf
vi /usr/local/webserver/freetds/etc/freetds.conf

　　输入以下内容：

引用

[global]
        # TDS protocol version
;       tds version = 4.2

        # Whether to write a TDSDUMP file for diagnostic purposes
        # (setting this to /tmp is insecure on a multi-user system)
;       dump file = /tmp/freetds.log
;       debug flags = 0xffff

        # Command and connection timeouts
;       timeout = 10
;       connect timeout = 10

        # If you get out-of-memory errors, it may mean that your client
        # is trying to allocate a huge buffer for a TEXT field.
        # Try setting 'text size' to a more reasonable limit
        text size = 64512

        host = mssql.yourdomain.com
        port = 1433
        tds version = 8.0
        client charset = UTF-8

　　 2、编译安装PHP自带MSSQL扩展
　　进入本地已存在的php-5.2.XX源码包目录：

cd /data0/software/php-5.2.XX/ext/mssql/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config --with-mssql=/usr/local/webserver/freetds/
make && make install

　　 3、在php.ini配置文件中增加mssql.so

vi /usr/local/webserver/php/etc/php.ini

　　增加一行：

引用

extension = "mssql.so"

　　 4、重启PHP FastCGI

/usr/local/webserver/php/sbin/php-fpm restart

　　 5、测试文件（test_mssql.php）：

<?php
header("Content-type: text/html; charset=utf-8");
$msdb=mssql_connect("mssql.yourdomain.com:1433","username","password");
if (!$msdb) {
        echo "connect sqlserver error";
        exit;
}
mssql_select_db("database_name",$msdb);
$result = mssql_query("SELECT top 5 * FROM table", $msdb);
while($row = mssql_fetch_array($result)) {
        var_dump($row);
}
mssql_free_result($result);
?>
