php安装dblib扩展,连接mssql的具体步骤

1、先安装freetds 然后修改配置文件

不要装0.82版本，会报编译失败

Compile Failure With freetds0.82

进到freetds目录下编译安装

./configure --prefix=/usr/local/freetds --enable-msdblib --enable-sybase-compat   --disable-threadsafe

make

make install

2、再装mssql

进到目录下编译安装

/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config --with-mssql=/usr/local/freetds

make

make install

3、再装dblib

进到目录下编译安装

/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config --with-pdo-dblib=/usr/local/freetds
make
make install

4、修改php.ini

extension=mssql.so
extension=pdo_dblib.so

tsql客户端连接的命令

/usr/local/freetds/bin/tsql -H 192.168.1.100 -p 1433 -U sa -P 123456 -D user

修改配置文件

/usr/local/freetds/etc/freetds.conf 配置文件位置
tds version = 8.0 //修改
client charset = UTF8 //新增

如果连不上数据库，就检查一下版本，将/usr/local/freetds/etc/freetds.conf中global选项中tds version = 8.0

如果查到的结果是乱码，更改/usr/local/freetds/etc/freetds.conf将global中添加了一条client charset = UTF8

Adaptive Server is unavailable or does not exist” error connecting to SQL Server from PHP    是没加端口引起的

要加端口不然连不上

'dblib:host=192.168.8.888:1433;dbname=xxxx'
