how to setup an external hard drive with USB port to a webserver with following configuration:
Centos 5.3
Cpanel (latest)
What I want to do is to format and mount an external hard drive by USB port to my server and take my daily cpanel accounts on it.
I have a dedicated server, and WHM cPanel
I have a registered domain with oneandone (mydomain)
So what I want is nameservers, ns1.mydomain.com and ns2.mydomain.com when people are viewing any of the sites on my server.
Basically i need to know, step by step on how to, do this, please I have read all the guides but they dont say exactly how oneandone point to my server, I think I have done most stuff on the server side.
So I want a site mydomain2.com they can change their nameservers to ns1.mydomain.com and ns2.mydomain.com and it links to my server.
I think i have only 1 IP with my dediated server.
how install vmware in my server?
because now we install vmware but it seems have wrong configuration in network setup then,
we have 7 Ip address i want make connection vps with bridging!
Just signed up for Knownhost VPS and have 3 sites (all on individual shared hosting) that I want to setup but I'm having a hell of a time trying to figure things out.
I've read the entire directadmin (site-helper.com) but still having trouble setting things up. I know what all the terms mean but i'm stuck on how to setup the DNS, what suppose to point to what, creating 3 individual accounts for the 3 sites, etc.
I've made a how to, based on my personal knowledge about upgrading a CentOS 3, RedHat 9, or 8?, Fedora Core, and maybe others, to the new CentOS 4.5 OS. (or CentOS 4.x)

Please post, comments, questions, etc. here.
I've myself upgraded many servers this way, (even, tonight, I upgraded another, so I finally decided to do this with all my notes)
First I want to say hello and thanks for the great advice I've gotten on this forum. You guys have saved me a ton of time and heartache in regards to hosting accounts.
I was told by my hosting company that a VPS account isn't designed to be an step up from a shared account. I always viewed a VPS account as the intermediary between shared and dedicated. The hosting company basically told me that a VPS server is designed as a testing environment and you can run out of resources pretty quickly in a production environment.
Is that true? Or are they telling stories?

If someone hacks my server (Softlayer) and delete everything (including the backups)- does that mean I will lose everything? Is there any way to have an external backup which is not accessible?

I have a script that will create a compressed backup file of my website files as well as a compressed backup file of my mysql databases.
What I want to do is create a script that will site on my external hard drive that will be connected to the internet and would have it automattically connect to my webhosting account (via ssh or ftp) and download the specifid backup files everyother day. My goal is to be able to have a backup file on my local hard drive here in case anything happens to the backups that are already saved to another webhosting server.

View 5 Replies View RelatedSo a few days ago we had the wonderful experience of migrating Virtual Private Servers from HyperVM to Virtuozzo. After spending endless hours attempting to migrate with vzmigrate, vzp2v and rsync we were getting very frustrated and were just about to give up. With this we decided to contact our datacenter SoftLayer who usually is able to help out. Like always they managed to rise to the challange and save the day providing us with a solution thay may not have been the best, but probably the only one. We must have searched the entire Internet looking for guides and after we found out a solution we knew it had to be posted so that the frustration we went through would never have to happen again. While this solution is a little timely and requires some work it actually isn't as bad as it sounds. Also we have created a little shell scripts that does a good amount of the migration for you. Below I have made step by step instructions so that there will no longer be "no answer" to this question. Also just to let you know we contacted Parallels and unfortunatly we were told that "I can not find anything in our knowledgebase". Basiclly useless support... they regurgiate their online knowledgebase to you. So below is the guide.
Pre-Requisites:
1. Download the Migration Kit zip that includes the shell scripts for the migration.
Migration Kit Download: [url]
2. You must create a new container in Virtuozzo for each HyperVM VPS that you would like to migrate. You MUST use the same VEID and I you need to keep the hostname the same. Also the OS TEMPLATE you pick DOES NOT MATTER!
If you are copying a customer HyperVM template don't worry cause the OS Template has no effect as far as I know. We transfered 30+ VPS's and the OS TEMPLATE made no difference.
3. Stop the container you created and mount it.
Code:
# vzctl stop <VEID>
#vzctl mount <VEID>
For LIVE MIGRATION SKIP TO STEP 4b.
4a. Stop the VPS on the source server (HyperVM) and mount it.
Code:
# vzctl stop <VEID>
#vzctl mount <VEID>
4b. Leaving the VPS running while migrating has a risk of posible database corruption. During our migration we did it this way and we experienced no issues so I think it is safe to say that in rare cases there may be problems but usually not.
5. Unzip the Migration Kit and be inside the folder where it was unziped.
6. Execute the shell script.
Code:
./migrate.sh <IP-ADDRESS>
IP-ADDRESS = the IP Address of the source VPS Node
7. Enter the CTID when the prompt requests it. (CTID = VEID)
8. Enter the root password for the server you are migrating from.
9. The script runs inside a screen session so to back out of it to do other things or start another migration you must hit:
Code:
CTRL + A + D
To list all the screens you have open.
Code:
# screen -ls
To enter a screen session
Code:
# screen -r SESS-ID
SESS-ID = the numbers before the period listed when you list all the open screens.
10. Once the migration is completed a broadcast message will alert you. Also if you check /var/log/migrate/migrate.log will contain all the migrations that have completed.
11. Once a migration has completed you must unmount the VPS and start it.
Code:
# vzctl umount <VEID>
# vzctl start <VEID>
If everything went "ok" than your VPS should start up without issues and should be just like it was on the old server. Lastly I would like to give credit to SoftLayer for the method of migration. Thanks again SoftLayer

View 11 Replies View RelatedIs there a Windows GUI software for remote Admining servers that run on Red Hat Linux?
FYI: Currently I use Putty for remotely managing our servers.
So if you can recommend a GUI like Windows desktop software for remotely Admining servers running Red Hat Enterprise, I would very much appreciate that.
FYI: we have like 10 dedicated severs, so a desktop GUI that would allow one to monitor/manage multiple servers would be best. But if the GUI that you think is best can only remotely connect/manage one server at a time, requiring disconnecting to connect to the other server to Admin it, that is fine.
Also, I would love to hear what you think is the best book, best tutorial and reference guide for remotely Admining servers running RHEL? I am not looking for one of those books that are 1000 pages, but something that is a few 100 pages and can be read in 1 month assuming a few hours per day of reading.
I have had great difficulty in setting up OpenVPN, so I thought, when I finally do get it to work, I will write a HOWTO, so other can hopefully benefit…
This guide was done using a FC4 VPS, running on Xen, it will work on OpenVZ, all you need to do is ask your VPS provider to install “tun support”.
1.First of all get a few additional repos, If you already have your repos setup, skip this step
If you have Fedora 3, follow these steps,
[url]
If you have Fedora 4, follow these steps,
[url]
If you have Fedora 5, follow these steps,
[url]
If you have CentOS, follow the “additional third party CentOS repos”
[url]
Then issue these commands, each line is a new command, anything beginning with "#" are comments so dont try to execute those.
Code:
yum update
yum install openssl openssl-devel
# openssl and openssl-devel may be installed already… so don’t worry
2. Right, now you want to install OpenVPN, here are the commands,
Code:
yum install openvpn -y
#Now check that it works
service openvpn start
service openvpn stop
3. A few things to setup before you can make certificates, issue these commands,
Code:
find / -name "easy-rsa"
#you should get an output like this…
/usr/share/doc/openvpn-2.0.7/easy-rsa
#Now, make a copy of the easy-rsa directory, to /etc/openvpn/ ( make sure you #have put the right version number in i.e. mine was -2.0.7, change if needed)
cp -R /usr/share/doc/openvpn-2.0.7/easy-rsa /etc/openvpn/
cd /etc/openvpn/easy-rsa
chmod 777 *
mkdir /etc/openvpn/keys
4. You need to edit the vars file, located in /etc/openvpn/easy-rsa
You can use any editor you like, I used vi.
Change the line
Code:
export KEY_DIR=$D/keys
to
Code:
export KEY_DIR=/etc/openvpn/keys
Also at the bottom of this file you will see something similar to this,
Code:
export KEY_COUNTRY=US
export KEY_PROVINCE=CA
export KEY_CITY=SOMEWHERE
export KEY_ORG="My Org"
export KEY_EMAIL=me@mydomain.com
Change this to your own values.
5. Now its time to make the certificates, enter these commands
Code:
. ./vars
Code:
./clean-all
Code:
./build-ca
# just hit enter to the defaults apart from Common Name, this must be unique
# call it something like mydomain-ca
Code:
./build-key-server server
Code:
./build-key client1
# remember that common name must be unique e.g. use mydomain-client1
# and YES you want to sign the keys
Code:
./build-key client2
# do this step for as many clients as you need.
Code:
./build-dh
6. We are almost done now… right we need to create a few config files, you can download my template from here,
Code:
cd /etc/openvpn
Code:
wget www.designpc.co.uk/downloads/server.conf
# make sure you change a few things in the server.conf file, like DNS
# servers
Code:
touch server-tcp.log
~ this makes the log file..
Code:
touch ipp.txt
this makes the IP reservation list.
7. You need to make a few changes to OpenVPN itself. Go to..
Code:
cd /etc/init.d/
edit the openvpn file
#Uncomment this line (line 119)
Code:
echo 1 > /proc/sys/net/ipv4/ip_forward
Add these lines below it, changing 123.123.123.123 to your public IP address,
Code:
iptables -t nat -A POSTROUTING -s 192.168.2.3 -j SNAT --to 123.123.123.123
iptables -t nat -A POSTROUTING -s 192.168.2.4 -j SNAT --to 123.123.123.123
iptables -t nat -A POSTROUTING -s 192.168.2.5 -j SNAT --to 123.123.123.123
iptables -t nat -A POSTROUTING -s 192.168.2.6 -j SNAT --to 123.123.123.123
iptables -t nat -A POSTROUTING -s 192.168.2.7 -j SNAT --to 123.123.123.123
iptables -t nat -A POSTROUTING -s 192.168.2.8 -j SNAT --to 123.123.123.123
iptables -t nat -A POSTROUTING -s 192.168.2.9 -j SNAT --to 123.123.123.123
iptables -t nat -A POSTROUTING -s 192.168.2.10 -j SNAT --to 123.123.123.123
Now install iptables if you don’t have it already,
Code:
yum install iptables
#test it
service iptables start
service iptables stop
8. Now for the client config files. If your client is a Windows machine, make sure you have installed OpenVPN, use the gui version, downloadable from here;
[url]
You need to copy a few files from the server to your client machine, here is the list, located in /etc/openvpn/keys/
## WARNING ## Use a secure way of transferring these files off the server, something like WinSCP.
ca.crt
client1.csr
client1.key
client1.crt
Put these files in this directory C:Program FilesOpenVPNconfig
Now you need to make a client config, here is an example..
PHP Code:
clientdev tunproto tcp#Change my.publicdomain.com to your public domain or IP addressremote my.publicdomain.com 1194resolv-retry infinitenobindpersist-keypersist-tunca ca.crtcert client1.crtkey client1.keyns-cert-type server#DNS Options here, CHANGE THESE !!push "dhcp-option DNS 123.123.123.123"push "dhcp-option DNS 123.123.123.124"comp-lzoverb 3
Make sure you edit any of the lines with comments above them.
Call this file client1.opvn and put it in C:Program FilesOpenVPNconfig
Make sure the file extension is .opvn not .txt
To connect right click on OpenVPN in the taskbar >> Connect
To test ping 192.168.2.1
I can find lots of info on getting started on designing a web site but not much on getting started on publishing/managing the site.
I have been bumbling through trial and error for several years now. I was on infinology with hsphere for awhile. I am now on hostgator with cpanel 10. (Shared-babycroc)
I would like the equivalent of a dummies book that addresses all those pre-made directories and files that come with an account, discussions on permissions, password protecting directories, hotlinking, email account management, add-on domains, subdomains, etc.
I would really like a basic overview so that I could have a better chance of understanding the forum discussions and help sites I do find.
One of my customer using google apps for his domain. He also fetch external emails using google mail solution.
Problem is all of his email accounts email fetched but his ISP email give error.
I check and found if he didn't use that ISP, Outlook also not check email and give error. Only he can check email when he logon on net with that ISP.
on webmail he can check using ISP site. Any other webmail services provider like mail2web.com not able to check emails.
Can any one recommend how I can bypass their ISP restriction security.
I have reach another decision. I never considered an external firewall for my server. It sounds like this would be beneficial to me to protect my interest.
Are all external firewalls the same?
What recommendations do you have for one, like name and where I can get one?
I am an IT manager at a small company. Currently we host an ASP.net based web application (on an IIS server) that we do most of our business on. It was grown in house and uses our MS SQL server. We are looking at expanding this application within the next few months, and I need it to be "bulletproof", as in almost zero downtime.
The website also references and pulls up scanned documents that we have on a NAS server. Currently it is around 300 gig worth of documents, but expanding around 200 gig a year.
Ultimately, I would like this to be hosted someplace where there is a constant backup of the SQL and website. And someplace I don't have to worry about the hardware, because I am a one man operation and don't have all the needed experience to deal with the web application.
would it be beneficial for me to host the scanned documents onsite, and have a hosted solution reference them back at our HQ? I could put them in a DMZ or something like that.
