ERROR 1045 (28000): Access denied for user 'root'@'localhost'
 
I've install xampp-linux-x64-5.6.14-3 on Scientific Linux 7.1 x64.

After installation of xampp, I tried to open mysql, and I got this error. This is the error messages and what I tried.

Ack. That's not a fix.

https://blogs.oracle.com/jsmyth/entry/selinux_and_mysql

shows something like:
Code:
semanage port -a -t mysqld_port_t -p tcp 3306
semanage fcontext -a -t mysqld_db_t "/opt/lampp/var(/.*)?"
restorecon -Rv /opt/lampp/var
If it's an internal host and not exposed to the internet, disabling I guess is ok.
But it's not something I'd encourage on forward-facing computers exposed to the internet.

Hope that Helps.

Compare to https://phe1129.wordpress.com/2012/0...er-on-selinux/

I just gurgled "Mysql selinux" w\out the quotes.
