Cant get mysql to start after adding bind address lin to cfg file
#1
I followed the thread here:

GUIDE: How to use XBMC with MySQL on Mac OS X

And everything seems to be working fine until i add the binding line shown here:

Code:
bind-address = ***.***.***.***

Once i add this line, the local install of SQL will not start.

Currently im using my Synology to host my DB but want to use this machine since its got better hardware and will take some load off of my Synology. The machine in question has the following specs, i spoke with the DBA's at my job about this and they say that DB is mostly about the Disk IO wich is why i really want to use this machine for its SSD.

MacMini
[email protected]
5GB Mem
128gb OCZ Agility SSD

Also on a side note, my ultimate goal is to have this machine serve as the main DB and have it replicate to my synology as a real time back up just in case i run into any issues

If you actually added that line to the my.cnf, rather than changing the existing line from the loopback address (127.0.0.1), which is the default, then that's why you're not starting.

You're only going to bind to one IP (the one that you've assigned to the NIC - hopefully it's static).

Oh...and why are you trying to offload your NAS server? (have you done some monitoring that suggests the CPU or memory has high utilization?) Me, I've loaded up my NAS server with a pile of functions, as it's always up it's handy to have these things being served by it.

From looking over the my.cnf, i dont see the loopback entry so i thought i needed to add the line as suggested.

Also are you saying that it needs to be the IP of the host machine? I though the stars where there as wildcards allowing access from other machines?

As for why, the MacMini in question will also be on 24/7 as it will be used for my torrents as well as the image cache for thumbnails (once i get that working). Reason i choose to do it this is way is that i wanted to use a fast SSD for all the images and DB allowing them to operate quickly, also my NAS seems to be holding up well with its current load but reviews have stated that it doesnt like to work on to many things at once, since i had the hardware laying around for the second machine, seemed logically to me to set it up for these tasks.

Here is my.cnf for review:

# You can copy this option file to one of those
# locations. For information about these locations, see:
# http://dev.mysql.com/doc/mysql/en/option-files.htmlf
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.

# The following options will be passed to all MySQL clients

# Don't listen on a TCP/IP port at all. This can be a security enhancement,
# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.

# defaults to 1 if master-host is not set
# but will not function as a master if omitted

# 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 format - mixed recommended

So it seems im an ass, changing the *** to the machines IP seems to have corrected the issue. Also i had some permission issues on my share drive that i seem to have corrected so my images should be copying to my shared location as well.

My next question is going to be about replication as i want to keep the DB on the Synology up to date as well as a back up. It doesn't have to be real time but maybe a sync every night will be great.

Don't beat yourself up. On linux systems the default in my.cnf for bind-address is the loopback address (as this is more secure) - it allows for services local on the box to connect to the DB (eg. many apps would use ODBC connections). Make sure that you've either configured a static IP address on the Synergy or you've done a reservation for that IP in your DHCP server (likely your wireless access point). If the IP changes your DB server will be unreachable again (unless you update the my.cnf again that is).

The two things that you were talking about - syncing the DB with another (passive) host to have another server ready to take over the load vs doing regular backups. You suggested you don't want to tax your NAS server too much. If you were to setup DB clustering between the Mac and the Synology box, then you're putting a comparable load on it (it's not like the database is going to have a lot of clients connecting to it). If you want to minimize load on the NAS, just do a backup. There should be lots of documentation on the mysql site on how to easily automate that task.
