[SOLVED] Unknown variable : write buffer while starting mysql.

[ynilesh]

Hello all,

Mysql version - 4.0
while starting mysql i am getting following error, but when i comment it is working perfectly. Is it something related to mysql version specific.

Error 1 :
080414 10:23:52 mysqld started
/home/y/libexec/mysqld: ERROR: unknown variable 'write_buffer=2M'
080414 10:23:52 mysqld ended

Error 2 :

hmm since mysql can't read the variable. Try replace it with "

key_buffer=2M

1. it was permission problem.
2. I forgot to enable [myisamchk] parameter which was causing second problem.

Anyway thanks for the help athlon_crazy.
