基于Linux下PHP连接SQL Server的FreeTDS配置_PHP教程

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);     

?>
