I have a CentOS 6.7 server with MySQL 5.1.73 installed.
I am trying to enable replication which fails because "mysqld_safe" cannot write to "/var/log/mysql/mysql-bin.index"; even though the directory exists and permissions as "drw-r-----".
If I "su mysql" then I cannot even list the contents...
SELinux is disabled (and rebooted system) so I cannot see what is wrong. Any ideas?
