How Do We Configure RAID1
Aug 7, 2007I would like to configure RAID 1 setup. Do I need extra hardware or if I have 2 hard drives can I set it up?

View 3 RepliesI never use RAID1, but consider to use RAID1 server.
Let's say one hard drive failed and the DC replaced it with the new one, I was wondering if the system will automatically copy the data into the new drive or we should do some commands to copy the data into the new drive?
I have to leave the Supermicro servers and use only Dell. I have this question.
There is a big difference in performance between these two RAID configurations?
Dell - 2 x 1TB RAID1 PERC6
Supermicro - 4 x 500GB RAID10 3ware 4 port
It is for use with webhosting.
I have 2*400gb H.D.D on my server.
I have run RAID1 (software) on my server. Is it posible to disable RAID1 and use secondary 400gb H.D.D as additional H.D.D (800gb) and add another 1000gb H.D.D on my server and run RAID1 on server again? For have mirror data as RAID1 in 1000gb H.D.D
What do you feel is better for a typical shared/reseller hosting server?
RAID 1 or RAID 5 (with three drives)?
If this is not in the right forum for this... I'm sorry didnt knew where else it may go.
I have to build a new server with RAID 1 and WHM/Cpanel installed (in fact i dont have to, but i need to learn ASAP and my boss gave me an old server for practice).
I've seen the installation guide of cpanel but the sizes of the partitions apply to a disk of 80 GB (i think so) so is there any way to calculate the size of the partitions, regardless of disk size? cuz mine are of 250 gb each.
I'm trying to install it on centos 5 on text mode, so far i have been able to successfully install the system (with partitions of any size... since is a test doesnt matter) with RAID 1.
After that i ran cat /proc/mdstat and in some partitions shows me this
Rsync=Delayed
I've read in some places that this is not a big issue... but in other places says it is... maybe i did something wrong
I plan to install one server with RAID with that run on a dedicated card which support FreeBSD. As i have not much experience in this,

How can setup software raid1 on centos 5?
Can you provide any refrence?
I see [url]but i dont know is this need to /boot partition or no? and if need to this, is it must set for raid1 too?
How can config LVM with RAID1 in text mode centos 5.3 installation?
I need to do it for xen installation.
I have configured a Xen setup on a dual xeon system with a 3ware 8506 2 ports sata controller.
Array is configured in raid1 and I am using LVM.
I get really slow accesses on the virtual machines, when I create a big ext3 system, the system is nearly freezing.
I just got 2 dedicateds, and while creating software raid 1, upon initial sync up I'm getting around 7 megabytes per second (6700 kb/s) in write speed I assume.
This is a quad core, sata2 setup...
Dedicated server has 2 HDD but I am not going to pay another $25/month for the hardware RAID solution (already stretched too far).
My plan is to install FreeBSD 6 and use Gmirror to establish a raid-1 "soft" mirror.
Advantages: Entire drive is mirrored including the OS. Drives can be remotely inserted or removed from the mirror set using a console command so its possible to uncouple the mirror and perform software updates on a single drive then re-establish the mirror only after the updates have proved successful.
Disadvantages: Lower I/O than hardware solution (not a problem for me) others???
I rarely see people consider software raid for a tight-budget server and I am wondering why? Could it be that other OS's dont have a solution as good as gmirror? Or is it just that crappy soft-raid in the past has left a bitter taste in admins mouths? Or perhaps admins need the extra I/O of hardware?
about the hd,there are two options, the first one is four 7200rpm sata to do raid 10,
the second one is two 10000rpm sata to do raid 1, about the performance, which one will be better?
some of my sites works good and some didn't work!

I have a question on how to set up (clone) two nameservers.
I have two VPS' with two IPs that are totaly independent of each other. Both running ispCP with Apache2, mail, ftp, mysql, AND bind9 as DNS managment.
So. I want these two server to be as independent as they are, BUT they should share NameServers with each other.
Something like this:
host1:
ns1.domain.com = host1
ns2.domain.com = host2
host2:
ns1.domain.com = host1 (or host2?? = inverted)
ns2.domain.com = host2 (or host1?? = inverted)
A lot of domains are running more then one NameServer, but I could not find any tutorial on how to "clone" the NS from one to an other. Is it enough to just add some kind of "transfer to IP setting" in bind, or do I have to have scripts that download settings and files from one server to an other regularly?
I have a problem in the last apache upgrade (apache 2.2.8 + php5) step .
exactly in "Configure Suexec and PHP"
I found this option doesn't have multi values as CGI or Suphp just I found none :
PHP 5 Handler none
PHP 4 Handler none
I must to return to build apache1 with php4 for I can see suphp and cgi in "Configure Suexec and PHP" "PHP 4 Handler" option .
On my server I'd like to keep sites as fast as possible and not drain too much on the server. I don't have many users, but I'd like to get it right the first time. What's the best DB engine to use? What about other settings? I'm not sure I should run caching yet, I'm not under much load.
The server is running on Windows.
how come I can't route all traffic through openvpn.
1. I was able to ping my client and server ip no problem. So the tunnel connection is fine.
The problem is i can't route internet traffic through openvpn.
I was able to ping from tun0 interface after i add below command
iptables -t nat -A PREROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE
root@host188 [/etc/openvpn/config]# ping -I tun0 4.2.2.2

However, my client can't ping 4.2.2.2 from vpn tunnel and I use tcpdump I saw the traffic coming.
downloaded WAMP5_1.7.0. Prior to downloading I was freaking out wondering if I was going to screw up my computer with software conflicts, but I pressed on. I read the Apache information regarding IIS / Apache conflicts. The tutiorial told me to check the services installed on my computer. The tutorial told me to look for a service titled "World Wide Publishing" The service (WWP) did not exist so I proceeded to the WAMP installation wizard. I installed it. Apache does not display in the services window. As if it does not exist. Apache will not fire up. From what I got from the instructions at Apache, it seems there are alot of modifications I can perform to setup Apache correctly. The long and short of it is I connot see my see what my HTML/PHP code is spitting out because Apache never fires up. Can anyone give me some pointers on setting WAMP up in plain ENGISH? Just a note, when I float my mouse over the Apache icon, a little mouse over windows comes up saying "one of two servers running". Is ISS enabled on my computer? I'm frustrated. Any help regarding this matter is worth a beer (or 12).

The fact is that Google is already listing my site but it is showing the full content of my HTML public folder! Everyone could search my site like an FTP! I don't really want that. How can I avoid that? I just want web browsers to show my web pages, not the folders neither my HTML public folder with all my files: scripts, photos, etc.

Between our Linux servers, I can get speed up to 80Mbps when transferring big files. However, between Linux and Windows, it's just around 800Kbps - 2Mbps. It shows in network connection properties that connected at 100Mbps, but not sure why it's so slow
Is there any setting I should pay attention? Running Windows 2003 on that box.
This is a instructional overview thread for those developers who are getting into setting up their own server with a LAMP (Linux Apache MySQL PHP) setup. The linux distro referred to in this thread is a centOS (fedora|redhat) setup.
Before Anything
- Make sure that your actual RAM is the same amount that is displayed by the server (there could be some BIOS restrictions on RAM so check for that).
Linux OS Installation
- Use a server system for the type of install.
------------------------------
- Setup you partitions with care:
- Make sure that everything other than /swap is an ext3 partition type.
- /swap (usually double the amount of space that your ram has but never larger than 4 gigs.
- /tmp (700meg is ok).
- /boot (100meg is ok).
- / (leave rest of the available space in the harddrive for this).
------------------------------
- Use GRUB boot loader
- Use DCHP only if your IP address changes due to the network. If not, then assign the IP address of the box.
- Assign the netmask if DCHP is not in use.
------------------------------
- When setting up the packages, select only what you need. Most of the time it's better to just install no packages and then install everything you need by yum (yellowdog update manager). If you do not select any packages, only the 1st CD of the linux install will be needed.
Linux OS Customizing
- Create a new user and provide it a password (with # passwd). Do not create a user with a generic or commonly known names used in any daemon programs (ex. mysql, apache, admin, user, php, postgresql).
- Disable the ROOT login in SSH (this means that when you login using the other user with SSH, you'll have to $ su to the root user).
- Install "Development Tools" with yum using group install if you plan to compile your own apache. If not then install apache with yum install apache.
Apache Settings
- Disable the extensions that you're not using for your website. If the server is only hosting one website, then there is no use for Virtual Hosts.
- Set the ServerLimit value to a suitable value so that users won't get locked out of the website.
- Change the User and Group directives to the newly created user.
- Set Options +Indexes to Options -Indexes so that the contents of directories w/o an index file will not be displayed.
- Change the DocumentRoot setting to the newly created user's home (~) directory. Or if you plan to use the default (/var/www/htdocs or /var/www/html) then assign the permissions of the user to that directory.
- Add apache as a start up program when the operating system boots up (this can be set in /etc/rc.d/local).
- Setup logs accordingly. If you setup image logging and your server has 20+ images per page then your website performance can suffer.
- Setup Error Logs to a suitable level.
- If any web pages are not displaying and the web server appears to be on when accessing it from the localhost (wget http://localhost) then disable or flush the iptables (/usr/sbin/iptables --fliush). You should also set this as a start up option for the OS.
- Use mod_rewrite to use modern URLs.
MySQL Settings
- Use --skip-name-resolve.
- Use --skip-bdb (if you're not using it).
- Use --skip-innodb (if you're not using it).
- Set a log for slow queries.
- Set the max_connections to a high value.
- Do not set a user with a wildcard ip-address. Only setup users with a specific ip.
- Use Query Caching for frequently used queries.
PHP Settings
- Disable Magic Quotes.
- Disable Register Globals.
- Disable Short Tags.
- Disable ERROR REPORTING if the website is not in development mode.
- Enable HTTP Only Session Cookies.
- Set Session Cookies to only be cookies (and not URL's).
- If sessions do not work, then set the session save path to a directory where the apache user has access to.
- Use Gzip Compression.
Optimizing Concepts
- Use an optcode cache for PHP (Eaccelerator).
- Consider using a static domain for CSS and JS files (this way the same cookies for the website won't be sent on each request).
- If your website uses alot of CSS and JS files per page, bundle all of them together into one request using mod_rewrite and php [url]
- For Apache, use the lingerD module (this reduces the amount of resources that are used when an apache connection is closed).
Here are some links for optimizing your server build:

I am running IIS 6 for testing & developing web sites offline before uploading the.But i am having little problem reagarding name server and how to configure sub-domain in name server,
View 2 Replies View RelatedI have 2 servers, 1 has its DNS sorted out, and I have a domain on it. The other is an unmanned dedicated server. I need to configure plesk, and I understand it needs a valid DNS to function.
What I want from the second server is simply for its pages, content etc to be accessed via the IP address, not a domain, as it is purely a media server. So how can I configure this? I created a virtual domain but the plesk server shows the default folder content and not the virtually created one, how can I get the server to point to my virtually created folder content?
