我不得不升级到 php 7.1，然后我通过 freetds 连接到 mssql 就无法正常工作了
- PHP 7.1.12-1+ubuntu16.04.1+deb.sury.org+1
- Ubuntu 16.04.3 LTS
- SQL Server 2008 r2
这tsql-C 命令
tsql-C 命令

尝试通过 tsql 连接
tsql -S 192.168.0.20 -U 测试用户 -P mypwd（与 tsql -S mssql_db1_freetds -U test_user -P mypwd 相同）
locale is "en_US.UTF-8"
locale charset is "UTF-8"
using default charset "UTF-8"
Error 20009 (severity 9):
Unable to connect: Adaptive Server is unavailable or does not exist
OS error 111, "Connection refused"
There was a problem connecting to the server
我真的不知道我错在哪里。SQLSERVER 配置没有改变。谢谢
答案1
我已将 /etc/freetds/freetds.conf 中的 tds 版本从 8.0（在 php 7.1 升级之前可以运行）更改为 7.0（典型的 MSSQL 服务器）。现在它可以运行了。
完成配置
