MySQL won't run when i am using XAMPP server

Question

This is the error log for the MySQL when I run it on XAMPP. I don't know how to fix it, it's always stuck on attempting to start MySQL service..

I tried changing the port but the result is still the same. also tried re-installing but the problem is still the same

thank you in advance.the error i get is as follows

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:
#
#    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
#    where you replace <host>, <user>, <password> by quoted strings and
#    <port> by the master's port number (3306 by default).
#
#    Example:
#
#    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
#    MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
#    start replication for the first time (even unsuccessfully, for example
#    if you mistyped the password in master-password and the slave fails to
#    connect), the slave will create a master.info file, and any later
#    change in this file to the variables' values below will be ignored and
#    overridden by the content of the master.info file, unless you shutdown
#    the slave server, delete master.info and restart the slaver server.
#    For that reason, you may want to leave the lines below untouched
#    (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id       = 2
#
# The replication master for this slave - required
#master-host     =   <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user     =   <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password =   <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port     =  <port>
#
# binary logging - not required for slaves, but recommended

Solution

It took me 2 days to find the solution. Here our friend Francis posted the solution which worked for me. I think the problem was corrupted files of mysql: https://stackoverflow.com/a/33413223/9106762

Simply navigate to your xampp folder -> mysql -> backup -> copy all files and folders inside it and paste them into xampp/mysql/data directory.

This worked for me perfectly (I tried to change my.ini, ports, resetting the services,... before but nothing worked). Hope it helps others too.

you could also try to reinstall it, have you tried it?

[Jandoe]

i have tried re installing it and still the same

[Jandoe]

i tried re-installing it but the problem remains the same.

[Adam Thomason]

Perhaps try checking config? If you could post it here, that would help.

[Adam Thomason]

# bind-address="127.0.0.1" # bind-address = ::1 # for ipv6 Depending on whether you're using IPv4/6, uncomment one of these lines.

[Jandoe]

I just tried right now but the problem and error log didn't change. :(

[rule_it_subir]

It worked for me. As you mentioned I've also tried changing ports but didn't work. Thanks.

[Gooner]

This absolutely work, after looking at the logs from the mysql error log, windows event viewer i finally found the problem.. The db had crashed and unable to repair, to fix this i've to copy backup and paste it back in data folder for mysql table to be fixed.

Hi, this work for me also, thanks a lot.
