Re: List Moderation

ross.coo...@gmail.com (Ross Cooney) — Fri, 08 Aug 2009 15:43:32 UT

I am now getting around five spam emails a day into the moderators
mail box.

To help stop this I have now closed automatic list membership and new
members need to apply to a moderator before they can join.

I hope that this stops the flood of spam emails that I have to deal
with every day and also opens the list up to faster communication.

I understand.
Micha, I have taken moderation off your account so that you can now
post to your hearts content ;)
I am happy to assign more admins to the list of that helps speed up things?

VideoPress

micahwal...@gmail.com (Micah Walter) — Fri, 07 July 2009 22:44:24 UT

I was just wondering if anyone had attempted to install Wordpress's
VideoPress on EC2... It requires a server for encoding as well as a
file server.. and I'm thinking it would be great to combine this
platform with CloudFront... anyone looked into this at all?

while I understand the need to fight spammers, the moderation of this
group is making it really minimal as a resource and usergroup... by
the time my questions are posted and then finally replied to, I have
usually found the answer elsewhere on other forums...

List Moderation

Hi List,

I setup list moderation on this google group for all new members a few
months ago so that I can stop spam being posted...we get around five
spam postings a day!

I hope that this explains why some of your posts take a while to
appear!

Re: Setting up a dual server LAMP host on EC2

micahwal...@gmail.com (Micah Walter) — Tue, 07 July 2009 01:03:16 UT

So I have been investigating how to do this with security groups and
rightscale... can anyone give me a rundown? I am not getting it so
far.. basically I want a group for my php/apache servers, and a group
for mysql server, granting access for those php servers to get at
master.mydomain.com instead of the internal IP address...

Hi Micah,

Yes - that sounds like a good plan. The security groups are pretty
easy to setup, especially if you're using RightScale.

Good luck, and let me know how you get on!

Matt,
Yes, this is sort of what I was thinking... so essentially the setup
would be...

1) Assign Elastic IP for MySQL node
2) Create DNS entry for it, such as master.mydomain.com or whatever
( I do this via godaddy )
3) set up a security group to allow my php nodes to access the default
mysql port

Hi,
As I mentioned in an earlier post, I have a two node setup currently.
Node A is a Apache PHP box that contains a few wordpress websites, and
Node B is the MySQL box containing DBs for these sites.

Both nodes have a EBS volume attached and all user-data, database
files and web application files reside on EBS.

Hi Micah,

Your best bet here is to use Amazon's elastic IP service to assign an
IP to your MySQL server, and map that to a domain, just as you
suggested. You can then point your PHP nodes to that subdomain, which
will resolve to the elastic IP, which you can point at the MySQL node
(or a cache, or a load balancer, or whatever). Elastic IPs are free

Matt,
Thanks for the advice. I will definitely look into security groups.
For now, I did some testing and if I grant access to a user for "Any
Host" this sort of solves my problem. Security seems to be set to not
allow connections from external hosts ( outside my subnet ) and this
includes other EC2 instances on other account.

Hi there.

I second what Matt Wood said: do not couple your elements tightly. Use the
access permissions.

Incidentally, most Cloud management software makes it much easier to do just
that. Check out RightScale <[link]>, or their open
source competitor, Scalr.net.

Hi Micah,

My advice would be to use the EC2 security rules to control access to
the MySQL server, rather than granting permissions on a host by host
basis.

As you probably know, by default, EC2 doesn't allow any incoming
connections, but you can manage which nodes can access which other
nodes using the access permissions in a security group. For example,

Ross,
I sort of guessed as much... However, I am thinking there must be a
better way of doing this. What if I want to spin up 10 php servers? I
would have to go in an grant access for each internal IP? This would
be especially complicated if I had more than one user...

Hi Micah,

The best way to do this is using the mysql statement that you have
already used:

You need to update your privileges every time that you add a new PHP
server.
