安装在linux下的mysql数据库，用navicate for mysql连接正确，可是库少了几个，求救

刚装完，也就有个test吧。其他的像 information_schema performance_schema mysql ,这几个库在navicate里面看不到也正好啊。反正又不动它们。。linux，你可以尝试用emma这个客户端，就可以全都看到。

etting up ODBC on CentOS 5.2

Pre-requisites

unixODBC needs libstc++.so.5 and libtdl.so.3, which can be easily installed using

$ yum install compat-libstdc++-33.i386 libtool-ltdl.i386 libX11 libXcursor libXext

Next, we need to install unixODBC:

$ yum install unixODBC

Then we need the ODBC Driver and Setup Library (both generic RPM version), which can be downloaded on the MySQL website.

There's a newer version 5.1 of the ODBC connector on the site, but it will not work on CentOS 5.2!

Once they are downloaded in a directory, install both using

$ rpm -Uhv *.rpm

Ok, that's the installation part. Now let's go to the configuration.

Configuration files

/etc/odbcinst.ini

[MySQL ODBC 3.51 Driver]

DRIVER = /usr/lib/libmyodbc3.so

SETUP = /usr/lib/libmyodbc3S.so

UsageCount = 1

Delete everything else, especially if there are other driver sections referring to MySQL. They will not work anyway.

/etc/odbc.ini

This file defines your DSNs. Let's take this example:

[mydsn]

Description = emma database on devel2

Driver = /usr/lib/libmyodbc3.so

Server = 172.20.8.141

Database = mydb

Port = 3306

Option = 3

User = yournamehere

Password = yourpasswordhere

Installing Driver/DSN

Now we are ready to install the driver and DSN (in this order):

$ odbcinst -i -d -f /etc/odbcinst.ini

$ odbcinst -i -s -l -f /etc/odbc.ini

For clients, which cannot use system DSNs and need user-level DSNs, execute this as the user:

$ odbcinst -i -s -h -f /etc/odbc.ini

Note the h (User) instead of l (System) switch! Couldn't be more obvious, right?

Let's check if your data source is listed now:

$ odbcinst -s -q

If so, well done! ODBC is running.

You can now connect using the isql tool, where you can issue SQL statements just like with the mysql client:

isql mydsn
