Can't create/write to file '/d/data/myhost.err' (Errcode: 13 "Permission denied")

Hello everyone,

I am installing MariaDB 10.1.21 on RHEL 6.7.

I am experiencing an issue when starting mysql service (/etc/init.d/mysql) from a custom datadir. So as you can see that my datadir is /d/data/, i put that info in /d/data/my.cnf:

[mysqld]

basedir = '/usr'

datadir = '/d/data'

tmpdir = '/tmp'

When starting using /etc/init.d/mysql:

service mysql start Starting MySQL. [FAILED]

And it logged nothing into the log file /d/data/<hostname>.err

So I digged into the /etc/init.d/mysql script and echoed the command when starting mysqld_safe:

/usr/bin/mysqld_safe --defaults-file=/d/data/my.cnf --datadir=/d/data --pid-file=/d/data/myhost.pid 170308 05:37:58 mysqld_safe Logging to '/d/data/myhost.err'. 170308 05:37:58 mysqld_safe Starting mysqld daemon with databases from /d/data /usr/bin/mysqld_safe_helper: Can't create/write to file '/d/data/myhost.err' (Errcode: 13 "Permission denied")

As checked the folder /d/data/ has owner mysql:mysql and permission 755 the file /d/data/myhost.err also has owner mysql:mysql and permission 755

I tried chown and chmod to 777 and the error was still there.

It would be great if anyone knows this issue and help me?

Great thanks.
