Hi Juan, I have verified directory permissions, its shown below.
linux76:~# ls -l /data/mysql/ total 535088 drwx------ 2 mysql mysql 20480 2008-05-04 23:44 dip -rw-rw---- 1 mysql mysql 10485760 2007-12-23 01:21 ibdata1 -rw-rw---- 1 mysql mysql 268435456 2008-01-13 01:17 ib_logfile0 -rw-rw---- 1 mysql mysql 268435456 2008-01-13 01:17 ib_logfile1 drwx------ 2 mysql root 4096 2008-03-28 02:58 mysql In error log file there is error. debian-sys-maint error The above error come while starting mysql for the first time. Then i have given the permissions for debian sys-maint from /etc/mysql/debian.cnf. After that restart mysql don't gives any error. still innodb is disabled.
