CentOS 5.4 Linux 下的 PHP(FastCGI) 需要連接相關部門的SQL Server 2000數據庫，配置了擴展FreeTDS擴展。

1、編譯安裝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

輸入以下內容：

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、編譯安裝PHP自帶MSSQL擴展

進入本地已存在的php-5.2.XX源碼包目錄：

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、重啟PHP FastCGI

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

5、測試文件(test_mssql.php)：

總結
