To start multiple servers manually from the command line, you can specify the appropriate options on
the command line or in an option file. It's more convenient to place the
options in an option file, but it's necessary to make sure that each server
gets its own set of options. To do this, create an option file for each
server and tell the server the filename with a --defaults-file
option
when you run it.
Suppose you want to run mysqld
on port 3307 with a
data directory of `C:\mydata1', and mysqld-max
on port 3308 with a
data directory of `C:\mydata2'. To accomplish this, create two option
files. For example, create one file named `C:\my-opts1.cnf' that looks
like this:
[mysqld] datadir = C:/mydata1 port = 3307 |
Create a second file named `C:\my-opts2.cnf' that looks like this:
[mysqld] datadir = C:/mydata2 port = 3308 |
Then start each server with its own option file:
shell> mysqld --defaults-file=C:\my-opts1.cnf shell> mysqld-max --defaults-file=C:\my-opts2.cnf |
(On NT, the servers will start in the foreground, so you'll need to issue those two commands in separate console windows.)
To shut down the servers, you must connect to the appropriate port number:
shell> mysqladmin --port=3307 shutdown shell> mysqladmin --port=3308 shutdown |
Servers configured as just described will allow clients to connect over
TCP/IP. If you also want to allow named pipe connections,
use the mysqld-nt
or mysqld-max-nt
servers and specify options
that enable the named pipe and specify its name. (Each server that supports
named pipe connections must use a unique
pipe name.) For example, the `C:\my-opts1.cnf' file might be written
like this:
[mysqld] datadir = C:/mydata1 port = 3307 enable-named-pipe socket = mypipe1 |
Then start the server this way:
shell> mysqld-nt --defaults-file=C:\my-opts1.cnf |
`C:\my-opts2.cnf' would be modified similarly for use by the second server.
