Server :: Setup Master / Master Mysql In HA Setup Without Use Of Load Balancer Provided By Host?
Mar 31, 2010I have a load balancer with 2 web servers behind it. The web servers rsync with cloud storage to update their apache directories 1 time every hour. Apache is just running php pages that pull/push data to a DB so they dont need to be updated that often. However I need to figure out how to implement a Master/Master MySQL setup to have my web servers point to for the PHP stuff. I need to implement it without having a single point of failure. The Load balancers are useless for failover as they only detect availability based on Ping request. So putting a master/master setup behind a Load Balancer is out. what is the best way to setup the master/master mysql in a HA setup without the use of a load balancer provided by the host?

View 2 Replies View RelatedServer :: Local Master Browser Do Not Sync Their List With The Domain Master
Nov 13, 2009I'm managing a residential network. Each flat is its own subnet, and can only communicate with the other flats through a router (i.e. no broadcast). 95% of these 300 subnets only contains windows computers (from lambda users).
My final goal is to be able to browse the entire network from any computer.
I set up a samba server acting as a wins server, and every computer is aware of it because it is registered in the dhcp. So name resolution is working fine for everyone.
The same samba server is set to be the "Domain master browser":
workgroup = WORKGROUP
wins support = yes
prefered master = yes
local master = yes
domain master = yes
os level = 65
When I browse the network (using "net view" or "browstat view"), I can only see the servers which are in the same subnet as the domain master browser.
Now, when in a subnet the computers arrange themselves to find a "local master browser", the only visible computers are the one in that subnet.
What I don't understand is why all the local masters don't synchronize their lists with the domain master.
So, to sum up, every subnet get the following behaviour:
-if a local master is elected, the only visible computers are the one in the same subnet.
-if no local master is elected, the only visible computers are the one in the subnet of the domain master.
-if I add another samba, configured as a local master winning all elections, then the magic is working and the lists are synchronized.
What is expected:
-every computer can see all the computer from all the subnets.

Server :: Rewrite / Redirect Directory To Port Number In Apache?
Jun 4, 2011I have a website example.com, serving pages on port 80. I want the url example.com/redmine to be rewritten to port 3000, where my redmine server is running, without actually changing the URL. So the user typing in example.com/redmine/test would serve up example.com:3000/test, without the user actually connecting through the port. I know this can work through CPanel, but I don't know exactly how it was implemented. I'm looked at how mod_proxy, mod_proxy_html, and mod_rewrite,
View 4 Replies View RelatedGeneral :: Transfer Large Number Of Files Host To Host
Oct 20, 2010I have two servers, one has an empty / and the other has a subdirectory with a large number (4 gig) with many, many files. I need a way to transfer the files en masse from the server with the large number of files to the one that is essentially blank.I don't have space on the used host to simply gzip all the files. I've googled this and see that there may be some combination of tar and/or gzip that will let me do this with some sort of redirection.
I really need and example line of how this can be accomplished. If my explanation seems rather sparse, I can supply more details.
Ubuntu :: Port Forwarding Crutch - Number Of Apps That Are Unable To Have The Outgoing Port Changed ?
Mar 28, 2010I'm not that great with mailservers, and just been thrown a curveball with a MS Exchange environment for which there is apparently no solution... yeah, right. But is there a workaround?
The problem is that the site mail (SMTP) needs to be sent via port 26 instead of the commonly used 25. Port 25 is mapped to a mailfilter, which apparently causes havoc with some of the mail, and the techs that have been on site trying to coax the Exchange server to co-operate have said that the only way would be to get rid of the filter.
The problem is that there are number of apps that are unable to have the outgoing port changed and so keep sending mail out on port 25.
I look after the Unix/Linux side of things at work, and I was wondering if there was an easy way to set up a Ubuntu box to receive mail on port 25 and just forward it to the MS box on port 26? So, in other words (and I hope this makes sense): monitor port 25, and forward whatever comes in on port 25 to the server on port 26. Simple portforwarding, or is it? What steps do I need to take?

Server :: Limit On The Number Of Virtual Machines Running On RHES / CentOS XEN?
May 2, 2009We've been experiencing sudden host server crashes minutes after starting a fourth virtual machine. Our setup looks like:
Dell Poweredge T300
1 x Intel Xeon X3323 Quad Core 2.5 ghz
16 GB Ram
CentOS 5.3 (64 bit)
Server is running a stripped down version of CentOS 5.3 (64-bit), running only the built-in Xen Virtualization Environment. There is no other services running on the server (not samba, httpd, sendmail, cups... nothing except Xen) We've created several virtual machines, and as long as we don't start a fourth virtual machine everything runs smoothly (impresive hardware).
Each virtual server is configured as:
PARAVIRTUALIZED
1 Virtual CPU
1 GB RAM
However, 5 minutes or so after starting a fourth virtual machine, the entire host server crashes and restarts itself. Are we limited by the number of cores on the host machine CPU (4 cores)? 1 for the host and 3 for virtual machines? We've read in forums about other Xen setups running up to 11 virtual machines on less powerful hardware? (a dual core server). Should we be using FULLY VIRTUALIZED virtual machines instead? Is the number of XEN virtual machines in fact limited by the number of cores? If so, how can someone run several virtual machines on a single core host?
By the way, we were replacing a previous Dell Server (Poweredge 2600 with 512 MB Ram and a single Xeon single core processor running Open Virtuozzo). We were able to run up to 16 virtual machines at the same time. Of course none of the machines endured hard work (testing environments, etc). But hey, my point is that we expected to get a much higher number of virtual machines on this new hardware.

Fedora X86/64bit :: How To Reset/decrease Scsi Host Number
Feb 17, 2011In /proc/scsi/scsi, we can see the scsi host no. (scsi identifier no.). for e.g. Host: scsi4 Channel: 00 Id: 01 Lun: 00 In above e.g., scsi identifier no. is 4. Whenever we modprobe a particular module associated with scsi devices, we can see new entry in/proc/scsi/scsi with a greater identifier no. When we do rmmod on that module, the entry from /proc/scsi/scsi wipes off but still the counter of scsi identifier no. doesn't decreases. is is there any way to reset or decrement this counter so that next time when I do modprobe on scsi related module, it will assign no.s starting with 0 ? I found that during registering a scsi device, scsi_register() method gets value from "next_host" (which is a static int initialized to 0) and then increments next_host counter. Also, during scsi_unregister(), it decrements next_host counter. rmmod internally calls scsi_unregister(). So, if it is true then why the scsi host id. doesn't decrement during rmmod?
