I am trying to set up a master-master replication between my cpanel server and another VPS but when I define log files in the my.cnf files, mysql does not reboot.

I am following this guide:

I needed to edit my.cnf file to set the values you will see below.
The steps I took were:

sudo cp -rp /etc/my.cnf /etc/my.cnf.bakup

sudo nano /etc/my.cnf

(added to the bottom)

server_id = 1
log_bin = /var/log/mysql-bin.log
log_bin_index = /var/log/mysql-bin.log.index
relay_log = /var/log/mysql-relay-bin
relay_log_index = /var/log/mysql-relay-bin.index
expire_logs_days = 10
max_binlog_size = 100M
log_slave_updates = 1
auto-increment-increment = 2
auto-increment-offset = 1

I tried to reboot mysql using WHM but it always failed saying the four log files I had defined did not exist. So I manually used nano to create them but even now I am getting the same problem.

Could you please help me understand how to create these files so that might be able to reboot mysql successfully?

I would make sure that MySQL has the correct permissions and ownership to access those files.  Since MySQL usually does not run as root it should not be able to write to files that you created either as root or as another user.

Try to change the ownership of the log files like this:
chown mysql:mysql /var/log/mysql-relay-bin.index
chown mysql:mysql /var/log/mysql-relay-bin
chown mysql:mysql /var/log/mysql-bin.log.index
chown mysql:mysql /var/log/mysql-bin.log

Open in new window

You may also need to update the permissions of those logs.  If so then update them to something like:
chmod 755 /var/log/mysql-relay-bin.index
chmod 755 /var/log/mysql-relay-bin
chmod 755 /var/log/mysql-bin.log.index
chmod 755 /var/log/mysql-bin.log

Open in new window
