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
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

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
/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);
- ?>
