当我使用 XAMPP 服务器时 MySQL 不会运行

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

Answer 1

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.

Answer 2

To me, this looks like the offending line:

2015-11-10 15:26:57 4348 [Note] Server socket created on IP: '::'.

It looks like MySQL isn't binding to your localhost, and therefore can't bind to a port on said host, and won't start because of that.

Check your config file in MySQL to make sure it's set up correctly. Failing that, a fresh install of xampp to restore defaults should do the trick.

EDIT:

For more info here, as far as I can tell, if you're using IPv6 then ::1 should be the loopback address for localhost. I'm not entirely sure what just :: is.
