unixODBC工作，但Apache不會連接

Question

我想設置Apache連接到Microsoft SQL服務器進行身份驗證。這並不理想，但這個遺留系統在MSSQL中擁有憑證，並且不能更改。我有unixODBC的設置和工作

**odbcinst.ini** 
[SQL Server Native Client 11.0] 
Description = Microsoft SQL Server ODBC Driver V1.0 for Linux 
Driver = /opt/microsoft/sqlncli/lib64/libsqlncli-11.0.so.1790.0 
Threading = 1 
UsageCount = 1 

**odbc.ini** 
[mssql] 
Driver = SQL Server Native Client 11.0 
Server = 192.168.250.200 
Database = DBName 

當我連接使用isql我能沒有問題

isql mssql username password 

+---------------------------------------+ 
| Connected!       | 
|          | 
| sql-statement       | 
| help [tablename]      | 
| quit         | 
|          | 
+---------------------------------------+ 

查詢數據庫，在Apache中我已經配置了以下

DBDriver odbc 
DBDParams "datasource=mssql,user=username;pass=password"   
DBDMin 1 
DBDKeep 2 
DBDMax 10 
DBDExptime 300 

當我啓動httpd我在錯誤日誌中得到這個

SELinux阻止了來自Apache的連接。
