mysql5 error

[kompi]

do not lose my current database?

I have a premonition of hacked into my server and installed backdor

 

[tillo]

No, your databases will remain untouched; they reside in "/home/mysql" and custombuild just recompile and reinstalls MySQL in "/usr/local/mysql-version" then create a symlink from "/usr/local/mysql".

It may be some bad rootkit, if you think there has been a security breach I suggest you hire a consultant to take a look at the server and possibly reinstall it completely from a backup.

 

[kompi]

ufff, I rebuild mysql, and all ok.

very thank you for your help.

I must secure my serwer.

 

[tillo]

You are welcome.

I may be of help securing your system, it's my full time job. Just contact me by Email if interested.

# 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

Shardik, did you read that message from tillo which you quoted? He's in the business of working on systems. That's why he said to contact him by email if interested.

In general those of us who are in the DirectAdmin administration business help on these forums as time and resources permit, but should you need to take advantage of our commercial services, then the forums are not the place to make the request.
