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 + + + + |
