connect to mysql by odbc in linux

原文：http://asteriskdocs.org/en/3rd_Edition/asterisk-book-html-chunk/installing_configuring_odbc.html

sudo apt-get install unixODBC unixODBC-dev

sudo apt-get install libmyodbc

On Ubuntu, the /etc/odbcinst.ini file will be blank, so you’ll need to add the data to that configuration file. Add the following to the odbcinst.ini file:

 

[MySQL]
Description = ODBC for MySQL
Driver = /usr/lib/odbc/libmyodbc.so
Setup = /usr/lib/odbc/libodbcmyS.so
FileUsage = 1

 

On 64-bit systems, you will need to change the path of the libraries from /usr/lib/ to /usr/lib64/ in order to access the correct library files.

 

 

In either case, you can use cat > /etc/odbcinst.ini to write a clean configuration file, as we’ve done in other chapters. Just use Ctrl+D to save the file once you’re done.

Verify that the system is able to see the driver by running the following command. It should return the label name MySQL if all is well:

 

# odbcinst -q -d
[MySQL]

Next, configure the /etc/odbc.ini file, which is used to create an identifier that Asterisk will use to reference this configuration. If at any point in the future you need to change the database to something else, you simply need to reconfigure this file, allowing Asterisk to continue to point to the same place:

 

[asterisk-connector]
Description           = MySQL connection to 'asterisk' database
Driver                = MySQL
Database              = asterisk
Server                = localhost
UserName              = asterisk
Password              = welcome
Port                  = 3306
Socket                = /var/lib/mysql/mysql.sock

 

On Ubuntu 10.10, the socket location is /var/run/mysqld/mysqld.sock.

 

Validating the ODBC Connector

Now, verify that you can connect to your database using the isql application. echo the select 1 statement and pipe it into isql, which will then connect using the asterisk-connector section you added to /etc/odbc.ini. You should get the following output (or at least something similar; we’re looking for a result of 1 rows fetched):

 

$ echo "select 1" | isql -v asterisk-connector
+---------------------------------------+
| Connected!                            |
|                                       |
| sql-statement                         |
| help [tablename]                      |
| quit                                  |
|                                       |
+---------------------------------------+
SQL> +------------+
| ?column?   |
+------------+
| 1          |
+------------+
SQLRowCount returns 1
1 rows fetched
$ exit
