Installing Mysql Community 7.5.16 on CentOS 6.8

[Arturo Puente]

I am trying to install Mysql Community 7.5.16 on CentOS 6.8.
I followed all the instructions in the installation, and almost got to
the end, but when I write the command

service mysqld start

For the first time, mysqld seems to be starting but suddenly goes down.
I am including all the information that the command gives me.

# cat /etc/my.cnf
[mysqld]
datadir = /var/lib/mysql #
socket = /var/lib/mysql/mysql.sock #
port = 3306 #
user = mysql #
explicit_defaults_for_timestamp = 1 #
slow_query_log = 1 #
slow_query_log_file = mysql-slow-queries #
long_query_time = 2 #
# #
[mysqld_safe]
log-error = /var/log/mysqld.log #
pid-file = /var/run/mysqld/mysqld.pid #
# #
[mysql]


First time start of mysqld
**************************

# service mysqld start
