Mysql master-slave replication

environment

• System: kalilinux
• Mysql:mysql-5.6.40-linux-glibc2.12-x86_64.tar.gz
• Mysql installation location:

root@kali:/data# ls /usr/local/mysql/
bin  COPYING  data  docs  include  lib  man  my.cnf  my-new.cnf  mysql-test  README  scripts  share  sql-bench  support-files

• Two instances of Mysql:

root@kali:/data# ls /data/mysql_3306/
data  log  my.cnf
root@kali:/data# ls /data/mysql_3307
data  log  my.cnf
