How Do You Create/generate Config Files
Jul 10, 2009
When deploying new server/servergroup/cluster to your IT infrastructure, deployment (simplified) consist of following steps:
OS installation: to do it over network, boot server must be configured for this new server/servergroup/cluster,
configuration/package management: configuration server has to be aware of the newcomer(s),
monitoring and alerting: monitoring software must be reconfigured,
performance metrics: a tool for collecting data must be reconfigured.
There are many excellent software solutions for those particular jobs, say configuration management (Puppet, Chef, cfengine, bcfg2), monitoring hosts and services (Nagios, Zabbix, OpenNMS, Zenoss, etc) and performance metrics (Ganglia, etc). But each of these tools has to be configured independently or at least configuration has to be generated. What tools do you use to achieve this?
For example, when you have to deploy a new server, how do you create configs for, let's say, PXE boot server, Puppet, Nagios and Ganglia, at once?

Is there any command to generate it? The httpd.include is there but httpd.conf is not picking it up. Suppose there is a "middle" man to connect the vhosts httpd.include and httpd.conf

I just went to a box for myself, and just realized that my ram is closing in on it's limit.
We have 1gb of ram, yet we have around 50MB left.
We run 2 forums, with around 200 concurrent to 2000 on peaks. ( Currently it's 200 concurrent. )
Just hoping somebody could take a look at my httpd.conf and my my.cnf to see if I should tweak anything.
Ran top shift+m, and find that alot of apache connections is using 5mb per process:

unable to get any php5 error logs
Here are my settings in the /etc/php5/apache2/php.ini file:
display_errors = On
display_startup_errors = Off
log_errors = On
log_errors_max_len = 1024
ignore_repeated_errors = Off
ignore_repeated_source = Off
report_memleaks = On
error_log = /var/log/php5/error.log
However unfortunately I never see any error log being generated in the /var/log/php5/error.log file?
Also with my shared hosting site one thing which I noticed was, due to some configurations set by them, the error.log used to generate in the folder where the error occured. This is a cool thing which they used to do, but I just dont understand how did they do that.

I followed the following KB to allow country to be identified via GeoIP in AWStats: [URL] .... It works well on one of my domain, but I had to disable first the stats through PLESK Admin, then to reactivate it, so it would regenerate the conf file in /usr/local/psa/etc/awstats/* for a particulair domain. I then followed this KB to re-calculate all stats with country identification: [URL] .... It works as well.
But now: How can I regenerate all the conf file in /usr/local/psa/etc/awstats/* ? Is there any magic command?

I built a web hosting server, the following is its state
Cent os 5
AMP server loaded updated (installed it as a complete suite during installation so it was all set to go with php mysql modules loaded)
webmin
usermin virtualmin
created 2 named based hosts.
now when i load up wordpress in a site and try to run install.php
the following pops up
"Sorry, I can't write to the directory. You'll have to either change the permissions on your WordPress directory or create your wp-config.php manually."
I had this issue before and research said to redo the entire server (tried everything and was fed up had fedora then"
you can have a look at www.itgrunts.com just click create config file and the errror pops up.
The php and mysql db work great on simple scripts but i dont know why this happens.
i worked with assigning the users and apache user to the directory and everything, no joy.

Display some text in a web browser from a file called text.txt
text.txt will have many lines and some of them I do not want users to be able to modify and overwrite.
config_item_1=user can edit
config_item_2=user should see but not edit (could be on any line)
config_item_3=user can edit
config_item_4=user can edit
The user has made their changes in the web browser and clicks submit. I then need this info to be saved as the text.txt file however some checking needs to be done first. Anything matching config_item_2 should be removed. This could be on any line. Anything not matching should be permitted and added.

On my previous server and on some other hosts, I was able to write to files (for example with PHP) without having to chmod the files first.
Now I cannot, and files are required to be chmoded properly so I can write to them.
I cannot even touch() a file with PHP.
Is there any way to have this permissions removed?
I don't want to chmod the all thing, all I want is to change the configurations so I can fwrite() or file_put_contents() normally.
I's a dedicated un-managed server, so basically any advanced configurations can be done.

How can you generate a Primary Zendid?
Here is what we get:
[root@test /]# cd /usr/local/Zend/bin/
[root@test bin]# ./zendid No primary IDs was detected. Try option 'allid' to see secondary IDs.
[root@test bin]# ./zendid allid
P:K66AJ-QD99H-R55T9-8LGHW
M:5S9EX-2JC3Q-CJ4E4-KFZPV
[root@test bin]#
Can a Primary Zendid be created? And if so, how?. This is on a Centos VPS with:

Customer has requested the following:
"Create a zend id for your machine." This is apparently for them to create a product key for their software and have to bind to it?!
I have never heard of this and have been unable to locate any information on it.
This is a Centos box with php 5.2.5 installed:
Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies
with Zend Extension Manager v1.2.2, Copyright (c) 2003-2007, by Zend Technologies

how to go about this or even what this is?

I am configuring a bind reverse DNS zone to use the $GENERATE statement. This works well. But If I add a single IP record after or before the $GENERATE statement I get 2 PTR records for that IP (which is expected I guess).
Does anyone know if it's possible to report only 1 PTR record for a single IP (host) record?

After successfully installing postfix+dovecot on Debian, I've run into a problem using Thunderbird email client on my home pc to receive email. I get: "Security Error: Domain Name Mismatch"
How, then, do to I generate a certificate for mail.mydomain.com?
Before installing postfix+dovecot, I created an MX record for mail.mydomain.com, and an A record for mail.mydomain.com. Should I have also added mail.mydomain.com to /etc/hosts?
When setting up Thunderbird, I told it my Pop Server was mail.mydomain.com. When I attempted to Get Mail, then I got "Security Error: Domain Name Mismatch".

How to be able to fix my problem that is related to the https using apache2 (enabling https in apache2) at opensuse:
By the way, my opensuse version is:
openSUSE 12.1 (x86_64)
VERSION = 12.1
CODENAME = Asparagus
1) At the /etc/apache2/vhosts.d/vhost-ssl.conf, and if I do not have a name (as the server will be accessed using its IP address), can I place in the ServerName 192.168.0.5? Do I have to place it 192.168.0.5:443 or it is enough to be 192.168.0.5?
2) Is there a relation between the SSLCipherSuite values and the used method to generate the certificate?
3) I am afraid from the way that I am using to generate the certificate and the ssl module that is coming with apache2 at my machine which has opensuse. How can I select the right way?
Actually I used following commands to generate the .crt, .key and the .csr:
openssl genrsa -des3
openssl req -new -x509
openssl x509 -req
And that was from this link: [URL] .... But did not work with me !
Meanwhile I am placing:
SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL
4) Do I have to configure the virualhost? Do I have to create files under the directory /etc/apache2/vhosts.d? Because I will have one application to be browsed .. nothing more.
