I'm a newbie in Linux. I try to install and run MySQL but when I start
it it's got failed and this is my logs :

180426 18:01:03 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql

What can I do?

I fix above problem But now I got this errors in Log:

and /etc/my.cnf content :

Looks like maybe a comment in one of the option files (such as /etc/my.cnf and any .cnf file included from that file) has become un-commented. Search through these files for "Disabling symbolic-links is recommended" and make sure there is a comment character (i.e. '#') in front of it, then save the file and try starting mysqld again.

I change /etc/ directory permission to 650 and MySQL run successfully.
it's doesn't run cuz the MySQL can't read and write in my.cnf file.
