Server :: RedHat - Unable To Create Cluster Luci Database Objects
Dec 22, 2010
I want to create redhat cluster on(vmware) OS Redhat Enterprise Server 5.5
Install Luci on node1
Install ricci on node2
Install ricci on node3
All the computer name records in all system host file. When I try to create new cluster( luci_install init) then showing error...
Status messages:
* Host stationx.example.com is already authenticated
* Host stationy.example.com is already authenticated
[dismiss]
The following errors occurred:
* Unable to create the cluster Luci database objects
***No any cluster.conf file created on any node
I have reinstall the node, but getting same error.
I came across this while trying to find a solution for my load-balancing clustering issue in another thread. Since I perceive this as something on its own, I decided to post a new thread. I came across this site to setup a two-server cluster using Conga - Luci and Ricci.
From my understanding, this is what was done:-
1. Both servers have luci running using a shared storage via GFS to provide a failover
2. Both (and same) servers have ricci agent running for the clustering
I'm aware that Conga clustering aim to achieve High-Availability.
1. Can it also achieve Load-Balancing?
2. If yes, would the guide from the link above be sufficient or would they be additional setup/pre-req to be done? Since I'm new to this area and there was no mention of load-balancing, I'm still wondering if this is what I need to incorporate.
I'm trying to build cluster computer system using redhat linux enterprise 5.5. And I'm on the step to set up the NFS mounting. (step 3 of part VI on this paper: However, I kept getting "permission denied" when I used the command "mount -t" to mount the slave node onto the hard drive of the master node. Even when I edited /etc/fstab file to make it automatically set up during booting, I still receive the same result. By the way, I've already logged in as a root user on both slave and master nodes.
what rpms should I need install for setting up redhat cluster on RHEL 5.0 I want to create two RHEL 5.0 nodes as one cluster having oracle database server installed. And please note I have created these two nodes on VMware server for testing purpose. is it possible for creating cluster of two virtual guests.
I am planning to configure RedHat cluster on vmware, i dont know how to configure, i googled a lot but couldn't find satisfactory docs for configuring, can any one provide me step-by-step or good docs to go ahead.
I have two node redhat cluster for mysql database.The problem is that after updating the packages on both of the nodes after and previously the sevices was not able to relocated on second one , even rebooting the server the problem occurs.While starting the service on second node it started on the first one.Other services are running fine on both nodes.I have checked the /etc/hosts, bonding and many more files and seems to good.find the log for reference.

I have added apache application into redhat cluster. If the apache process failed, it will cause the service group fail over. I want to disable the application monitoring. I search throung Internet and it depends on the apache init script. If I change /etc/init.d/httpd status always return 0(success). THe service group will not fail over even apache failed.
However, I want to remain the application monitoring but stop failover. If the application like apache failed, I want Redhat cluster to try restart the application like 3 or 4 times. If restart failed, it will not failover.
Im having a frustrating issue with my two machine cluster I setup using Conga. Everything was working great except now when lucci starts mysql the port (3306) is never opened to outside machines. I can do a "ps -ef | grep mysql" and see it running as well as login to mysql on the node it is running on - but an nmap of the machine does not show the 3306 port and I cannot login to mysql remotely and yes I turned off all iptables(iptables,ip6tables) and SElinux is disabled.What am I missing here? If I start mysql on my own (and it is using the same my.cnf as lucci is) it does show the port open and works perfect,t for some reason when lucci starts it, no dice
I have installed Redhat Enterprise Linux Server 5 on my laptop. I want to install Oracle 10g database on RHEL5 server. I want to know whether any additional rpm's need to install before installing the Oracle 10g.
I am trying to create a cluster using conga and i am stuck at creating a fencing. I have no idea as what fencing device i have on my server or what fencing method to choose in creating the cluster. Can someone help me in this issue. I am trying to create cluster with 3 nodes (dell r910 machines with dell md3200 storage array )running redhat linux.
I am new to creating make files. I have been able to create simple makefiles for those applications which do not involve database but am unable to create for the ones that do involve database.
That's how my make file looks
Code:
clean:
tar:
There is no error in the code because when I compile the code through the following command, it gives me no error
Code:
The error msg is:

Where am I going wrong? Am I not providing the correct mysql path?
After the Opsview packages have been installed, it is necessary to configure Opsview and its databases.but while running below command get an error,#mysqladmin -u root password {password}mysqladmin: connect to server at 'localhost' failederror: 'Access denied for user 'root'@'localhost' (using pa
I have installed on a remote server phpmyadmin 3.3.1 and mysql 5.1.46 on a centos 5.4 OS.
Any newly created user with phamyadmin is unable to login both from mysql command line (from localhost) and phpmyadmin (localhost and remotely).
No prob when the user is created with mysql command line (from localhost). All of the users created with phpmyadmin, are not "visible" recognized from the show user command via the mysql command line. The setting I used when I create any user was the same as the ones with the mysql command line creation.
The error message I get when accessing from mysql command line (from localhost) is the following: "Access denied for user ... @localhost (using password: yes)"
I am now able to create the database using PHP and SQL. But it seems I can only do it as MySQL root user.. $dbuser = 'root'; but is there a way to do that as a regular MySQL user?
i installed Fedora 14 on my machine,then i installed postgresql in it i started it and configured it after seeing link [URL] i am able to do su - postgres but when i am trying to create database in it am getting error,It is asking for password then i am giving my root password

I m Not able to do complete my cluster Configuration. I have done my Cluster configuration but when i m running the system-config-cluster command the cluster configuration window appear, but after closing the window it is giving me the following error [root@node1 ~]# system-config-cluster. # when the window opens, I get the below error. When I did a search everthing pointed to the 2 rpms. I verified the version of the rpms cman and openais, they are:
cman-2.0.98-1.el5 openais-0.80.3-22.el5
error code res was not 0, it was 1 error string was /usr/sbin/cman_tool: Cannot open connection to cman, is it running? When I try to issue service cman start, I get the error:
I need to create a server for a database that has a .db file that is over 800Gb. now my first disk is 50Gb and i do the standard

now I have a second 1.2T that i want to be /opt is there a way to set up 4kib block size in ext3 in the os install? or should I do it after the install? Is this block size even big enough?
I am trying to configure redhat cluster first time but no idea how to do it. I am using rhel 5.2. I have copied cluster rpms from redhat media and tried to install them but facing alot of dependencies problem. Can some one please guide how can i do redhat clustering from start. I am doing this for configuring single node clustering for zimbra suite but it is the requirement to configure redhat cluster first. One more thing i am using two virtual machines installed by using virtual box.
I'm having a very strange problem with red hat cluster. After testing it in the lab, I tried to install a new cluster and received the following error: cman not started: Cannot start, cluster name is too long or other CCS error /usr/sbin/cman_tool: aisexec daemon didn't start I've checked the internet for that error, but nothing. I decided to to take the example from cluster.conf man, which looks like that :
[Code]...
And still I get the same error. I can find my servers both from DNS (FQDN and short name) and they also appear in /etc/hosts.
I 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.
I use bind 9.3.4 on RedHat 5.3, and I try to create some simple DNS related scenario. I have two DNS servers. One of them serves rodnower.org. zone and an other service web.rodnower.org. zone. The parent has glue record to child. I sussessfully query all rodnower.org. records, but failed to get data from subdomain. So here relevant data from namd.conf of parent zone:
Code: view "main" { zone "rodnower.org" IN { type master; file "rodnower.org.zone";
I was given task to install redhat linux os on one of the compute node on server which doesn't have cd/dvd drive or usb port.I have installation media as well ISO image. This server is on network, so I can access it via my PC which is running window 7.I think, I have 2 choice to install:1. Copy iso image to head node on server and then install linux os on compute node via nfs.r2. Use my PC dvd drive to install linux on compute node via network.But I don't know how to do it.
i am using the redhat cluster suite (luci and ricci) on my centos 5.3. i have 2 nodes in a cluster. when i poweroff the first node on wich a vm service is running, the service switchtes to node2. so far, so good :) but when i restart node1 the service is not failback to node1! i have created a failover domain with both nodes and priorized whre node1 has prio1 and node2 has prio2.
I have a 2 node RH 5u4 64-bit. I have installed and configured the latest Veritas CFS (Cluster File System) which also uses Veritas Cluster Server. File system if VxFS. Storage is on EMC Symmetrix arrays with Veritas Mirroring between the arrays.We have noticed that running 'du -hs' on the shared directory/filesystem where it takes about 3 minutes on one node and 30 - 45 minutes on the other node.I've been running strace on 'du'.'du' runs an 'lstat' on each file (66,000+ files). On the slower node, the ave time spent in 'du' is about .001 seconds longer, which accounts for the 30-45 minutes. Also, the standard deviation is much larger, which means to me that the lstat times are all over the place!Another interesting thing is that iozone profiling shows that the i/o rates from both nodes are darn near identical, with no anomalies at various buffer & file sizes! And, iostat looks really good as does 'vxdmpadm iostat show
