WARNING: Experimental code and known to crash computer.
|
|
|
|
Instructions, how to get this stuff working:
|
|
1. Make sure you have ORBit, includeing development libraries installed. They should be version 0.5.3 or later.
|
|
- I am lazy man and use default ones included with my RedHat:
|
|
[root@localhost /root]# rpm -qa | grep ORBit
|
|
ORBit-0.5.3-2
|
|
ORBit-devel-0.5.3-2
|
|
[root@localhost /root]#
|
|
|
|
2. Prepare kernel to include korbit:
|
|
- Get Linux 2.4.1 kernel source. (very possibly this patch works on 2.4.0 without modifications too)
|
|
- unpack it
|
|
- apply patch named "korbit-kernel-2.4.1-patch" on it.
|
|
- make menuconfig
|
|
- In section "Networking options":
|
|
...
|
|
[*] Kernel ORB (EXPERIMENTAL)
|
|
...
|
|
<M> CORBA User-space FileSystem (EXPERIMENTAL)
|
|
...
|
|
- make dep ; make bzlilo ; make modules ; make modules_install
|
|
- reboot
|
|
- Execute: insmod /lib/modules/$(uname -r)/kernel/net/korbit/modules/CorbaFS/client/corba-corbafs-client.o
|
|
You should see "gethostname() = localhost". Look at known bug 3 in the end of this doc.
|
|
|
|
3. Make sure MySQL server is working on your system
|
|
- On my RedHat 7.0 I execute "/etc/init.d/mysqld start"
|
|
|
|
4. Prepare MySQL FS daemon
|
|
- Get MySQL 4.0 from repository OR get MySQL FS source from http://no.spam.ee/~tonu/mysqlfs.html
|
|
- unpack it. In MySQL 4.0 source this is located in directory named "fs". cd into it.
|
|
- make
|
|
- Execute command "./RunServer"
|
|
|
|
5. mount MySQL server to disk tree
|
|
- Execute command "mkdir /mnt/mysql"
|
|
- Execute command "mount -t corbafs -o `cat /tmp/mysqlcorbafs.ior` none /mnt/mysql/"
|
|
- Check you SQL server content by executing "ls -la /mnt/mysql/"
|
|
|
|
Known bugs:
|
|
|
|
1. User bugs. fix user ;)
|
|
|
|
2. MySQL FS daemon will crash or will be stopped when cobrafs is mounted, then there is no way
|
|
to unmount disks anymore. This is korbit business to handle such cases and I had no time to dig
|
|
into korbit code.
|
|
|
|
3. host name returned by gethostname() should be "localhost" or korbit will crash. Also "localhost"
|
|
must be first string after 127.0.0.1 in /etc/hosts
