View 1 Replies View RelatedI am trying to setup Rocks Cluster on a Cluster containing 1 Master node and 23 slave nodes connected via a Switch. The master node's eth1 is connected to public IP and eth0 is connected to the slave nodes via the switch.
I was able to install the Rocks cluster on the machine, I configured the IP for master through DHCP. When I run the command 'insert-ethers' on the master node, it doesnot get me any slave nodes.
setting up the Rocks cluster on all the nodes?

View 4 Replies View RelatedI am trying to configure a system to boot Windows XP, CentOS 4 and RHEL5. I have one hard drive that contains both Windows XP and CentOS 4, and a separate drive that contains RHEL5. Until recently, I only had one SATA cable, so I could only connect one drive at a time. Under this configuration, everything works fine. When the RHEL5 drive is connected, I can boot into it. When the Windows/CentOS drive is connected, I can dual-boot into either OS. (GRUB was configured on this drive automatically when I installed CentOS into a new partition.)
Opening the box and moving the SATA cable is a lot of trouble, so I finally got a second SATA cable and enabled both SATA0 and SATA1 in the BIOS. I currently have the Windows/Centos drive as the primary, and I can still boot into both Windows/Centos. Now, I want to add RHEL5 to menu, but I can't find the file GRUB is using to present its menu at startup.
I have configured GRUB before on other systems, but I just know the very basics, such as where the grub.conf file should be. So, I spent a whole day reading advice online and asking friends who might have experience with these issues. Here are the steps I have taken so far:
I confirmed there is no /boot/grub directory, and /etc/grub.conf is a broken soft-link to /boot/grub/grub.conf. I did a find for grub.conf, which found nothing. I did a find for menu.lst, which found one item -- an example GRUB config file in /usr/share/doc/grub-0.95. I noticed that when CentOS boots, I see the GRUB commands printed to the screen, the first of which is:
root (hd0,2)
So, I did a grep -R "(hd0" * at the / directory, which also found only one item -- the example menu.lst file in /usr/share/doc/grub-0.95. I discovered that I can go to the command line grub from the grub menu and do:
cat (hd0,2)/grub/grub.conf
The cat command returns a printout of the grub configuration the system is obviously using. I didn't create this file, but the titles are identical to what I see in the GRUB menu, the default boot is Windows, and the timeout is very short. This must be the file. It looks like:
default=2
timeout=5
splashimage=(hd0,2)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.9-89.ELsmp)
[Code].....
I've also tried making the RHEL5 drive the primary drive. In that case, I can modify the existing /boot/grub/grub.conf file and see my changes at the GRUB boot menu. However, I can't get Windows to boot in this configuration. I've done a lot of google searching on the topic and added map commands to make Windows think it is on the primary drive. But, I'm still unsuccessful on this front as well. I think I'm closer to solving the problem with Windows/CentOS as the primary. However, if you think I will have more success with RHEL5 as the primary drive, I can provide more details as to my current grub.conf on that drive in a later post.
I have set up a nis slave server on Fedora 14. It was set up on a laptop so that the user can log in when he is at home (no NFS, local home dir). However, whenever the eth0 is disconnected, ypbind fails.
I have tried the same setup on a RHEL 4 (configured it as a slave server) against the same master nis as on the Fedora 14. Disabling eth0 on it however does not fail ypbind.

View 6 Replies View RelatedI configured a master DNS server 192.168.2.10 working OK. After that I configure a DNS Slave Server (92.168.2.11)the initial replication worked fine. This is test environment for my certification. I see how the zones from my master are transferred
zones in Master
training.com.db
transferred zone to my slave when I started named service
sec.training.com.db
That's Ok but I added some IPs to resolve to my master zone

fileserver IN A 192.168.2.31
I restart/reload named on master and after that I go to slave and restart/reload but zones wuth the new values are not replicated. How long does it take for slave to take the changes from master? how is the procedure manual or automatic? I see If I go to slave and delete sec.training.com and restart named the zone with the changes is transferred but that is very manual... I am including my DNS Configuration so you can take a look.
I have bind configured with Internal and External views, but the slave server is transferring only the Internal zone files for both Internal and External - a diff shows no difference, and the log shows the same serial number.What am I missing in the config so the slave server properly receives updates from the master for both views?
View 2 Replies View RelatedI recently set up replication on a production server and some rows are not making it to the tables on the slave. After 3 days I can see 200+ entries (of 161,000~) that are on the master and not the slave. Logs under /var/log including mysqld.log, mysql.status, messages do not show any problem.I have already tried dropping the DB on the slave and setting up the replication again by doing a stop slave, set slave options such as were in the logging to start, drop table, restore the dump previously made by the master, start slave, but the issue persists.
I following the documentation on the MySQL site for setting up replication so I'm not sure why this is having issues.What can I do to investigate and fix this?

I have set up a master BIND DNS server with 2 slaves. All the services start up fine on all 3 servers, but zones and named.conf info is not being replicated. The 3 servers are tentatively installed on a Xen virtual server for testing purposes. All 3 servers are 64bit and installed with: -> CentOS release 5.4 (Final) - 2.6.18-164.10.1.el5xen -> BIND 9.3.6-P1-RedHat-9.3.6-4.P1.el5_4.2
All 3 servers are fully updated. All 3 servers have static IP addresses. The services on all 3 servers start up without any apparent issues. Master server: # /etc/init.d/named restart ; tail -f /var/log/messages

So I think it is something in the named.conf file? I appreciate any extra set of eyes on it. Just feel like I'm so close!

I have a large environment with many VLANs and NIS slaves serving the VLANs. Previously we have not used a securenets file (don't worry; we don't use NIS for passwords, just NFS maps), but I'd like to start. The number of NIS slaves makes it annoying to update a securenets file on each when we add a new VLAN. Is there a way to propagate the securenets file to each slave when I update it on the master?If not, I guess I can live with propagating the file once and only visiting new slaves when I build them, because in 99% of cases a NIS slave only serves its own subnet.
View 1 Replies View RelatedI have configured master and slave Bind servers. Everything works fine. But whenever I add a new zone entry at master server it is not getting updated at slave server in logs I see this error:
client 192.168.1.1#43428: view external: received notify for zone 'yourdomainname.com': not authoritative
At master server I do not see any error or warning message. This error clearly indicates that named.conf file does not have zone entry in it or domain name is wrong. While checking the named.conf file I see that the zone entry has not been updated at slave server. If I update it manually and reload named on slave then zone files (db files) are getting created without any issue and any modification at master server for the zone records are also getting updated. My concern is why zone record is not getting appended at slave server in named.conf file.
Is there anything I am missing in the configuration. I am pasting the steps which I have followed to configure my master and slave server:
Configure Bind as master and slave server
Install Bind on your server
yum install bind
OR
sudu apt-get install bind9
Generate RNDC Key using the command
rndc-confgen -a -k rndc-key
it will stored in /etc/rndc-key file

im running two name servers using bind9 in my infrastructure. both are identical distros ubuntu 10.04Both are also receiving updates from each other, so no worries there.The issue is, when the master name server goes down, the slave for some reason doesnt take over and act as a primary name server. Can someone please help me on how to enable this feature using bind9?What basically I want to happen is when the master server goes down, slave will take over the primary role till the master comes back online

1. Now I need to set up LAMP servers with MySQL master/slave replication and Apache rsync.
2. Next i need to add BIND to both my Load Balancers with master/slave backup and replication...
Are there any guides to look at to follow on these? Can tou point me to the right direction for BIND with replication.
