I have a fedora 8 server and I just wanted to install fedora directory server I got it install and running, but I'm unable to check the replication and also it seems that I has no database when I user fedora-console-idm.[URL].. Also the same thing happens at the web tool. Any ideas? I think there is no db set, but I have no idea how to do this on fedora-ds. I'm new to it.

I am looking into setting up replication in a production environment but currently this is on two test machines. I am following the documentation at [URL] but I am unable to get past "16.1.1.10 Setting the Master Configuration on the Slave". When I do the CHANGE MASTER TO I am getting a syntax error for some reason. What am I doing wrong? These servers run "CentOS release 5.5 (Final)" and "MySQL 5.0.77-log Source distribution" installed via yum. The only changes from default are that I created a single database on the master before doing the table lock and dump, then everything else has been done exactly to what the documentation states, but is still failing.
The option skip-networking is not in the config file on either server and neither one runs SELinux or any firewall.
mysql> CHANGE MASTER TO
-> MASTER_HOST='192.168.1.220'
-> MASTER_USER='repl'
-> MASTER_PASSWORD='removed'

I'm running RHEL 5.5 on two workstation for test DRBD and I get something that sound strange ...[URL] Quote:Protocol C. Synchronous replication protocol. Local write operations on the primary node are considered completed only after both the local and the remote disk write have been confirmed. As a result, loss of a single node is guaranteed not to lead to any data loss. Data loss is, of course, inevitable even with this replication protocol if both nodes (or their storage subsystems) are irreversibly destroyed at the same time. By far, the most commonly used replication protocol in DRBD setups is protocol C.

View 1 Replies View Relatedi had configured a MySQl Replication Server with 2 DB Servers.Now we are planning to implement a failover Scenario.If Master fails The slave should act as a Master and we have a addition server.It will be going to act as slve.i had mentioned the points below..
Replication
(Master Server)----->----(Slave Server)-----------(Additional Server)
DBS 1 DBS 2 DBS 3
1.Replication is made between Master (DBS 1) and Slave (DBS 2) (successfully done)
2.If Master (DBS 1) failed Slave (DBS 2) should act as a Master and Additional Server (DBS 3) needs to be Slave
3.Whenever Orginal Master (DBS 1) became online the current Master ie ..Slave (DBS 2) should go back to Slave position and all lost data will be replicated to Master DBS 1.
I 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
webserver IN A 192.168.2.30
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.
Might this is silly question but I am not much familiar to database.I am doing master slave Mysql replication for load balancing. On master server different database has different user privileges. I create backup using mysqldump command and restore on slave server instead of using load data from master; command.When i replicate database from master to slave will i require to set user privileges same as master ?One more question: How to lock all database in mysql?

View 1 Replies View RelatedI have just re-installed Ubuntu 10.04. -The installation went smoothly, completing in approximately 25-30 minutes. All of my hardware, including keyboard, mouse, monitor and network interface has been detected and works properly. I am currently using the machine to type this. I can browse the web using Mozilla Firefox. My network connection does not start and stop; the machine remains connected with no indication that there is a fault with the NIC, and so on. I am able to download files at 150-170kB/s as is normal for me with Firefox.
I have not yet installed a graphical user interface to configure the firewall. I have not in any way worked with any system files. I am using the same hardware that I have used for approximately one year before this with no incident. I first encountered this with my previous install at approximately 3:00 AM (local time,) when I manually started Update Manager and attempted to check for updates in the default repositories. I have not altered the repository list in either the previous install or this new install. The Update Manager is entirely default.
Upon checking for updates, the list of repositories hangs after I believe at least ten lists have been checked. All of the lists checked before this hangup read "0 B" in the downloaded section of the window. It appears that upon checking for updates, no actual data is transferred to my computer. Again, after going through several of the default repo lists, the entire process halts. A wait of approximately ten minutes still reads that the process has not continued. -During this time I am able to browse the web using Firefox, and the OS seems to be responsive and otherwise functional. There is not a slow response from the keyboard or mouse, there are also no graphics glitches. Again, this problem first occurred with my previous install of Ubuntu 10.04, which was up-to-date as of approximately midnight last night. I have reinstalled the OS and the problem persists. The symptoms of this problem are consistent between my previous install and the reinstall.

View 7 Replies View RelatedI have two computers (one tower, one laptop). On both the computers, I have apache & PHP & mysql running, so i can program/script anywhere I like. With a simple sync'ing program, the PHP scripts are synced between the PC's, thought the databases arent. Therefor I'm looking for a method to sync (replicate) the databases between the PC's. thought after setting up some configuration, i'm stuck... now with how to, but what to
Option 1) Multi-master replication between the PC and the laptop. With this setup, the database can ONLY sync once both the devices are turned on. Also it can only sync if they are turned on on my LAN, since they do not have an external static IP address. if I turn on both PC's on my LAN, with static IP's (from the DHCP server), this option will work. Thought, I basically never have both pc's turned on in my own home... cuz i can use only one at the time anyway.So I was thinking of another setup
Option 2) Multi-master replication with: online Server, PC and Laptop. The server basically contains the most up to date database. for example, the laptop updates the server and the server can update the PC later, once the PC is turned on. Also the other way around, the PC can update the server which can than update the Laptop.
There is, if i'm correct, only one problem: the only multi master replications setups I found, use a circulair setup... (1 updates 2, 2 updates 3, 3 updates 1) What I need is to have the PC update the server, but ALSO have the server update the PC (same for the laptop)
than there is another (little) problem: the PC and laptop cannot be reached from behind the modem, nor do they have a static IP. My question: Is it possible to sync the server with the laptop (that has no static IP), the laptop with the server (that has a static IP), and the same for the PC
PC <====> Server <====> Laptop
I am IT Manager. Currently I am responsible for a mostly IBM shop, running a mix of AIX, OS/400. VMware, and Windows.
My P-series running AIX and Oracle and my AS/400 both back up to tape drives daily.
But my VMware system is not being backed up, the virtual machines are, but my tape drive just broke down.
I just ordered a server grade machine with an i5 CPU, running 3 2TB SATA drives in RAID5, this is going to be my new backup server.
I am hoping I can put Linux on it, and some sort of open source file replications, real time backup software that will back up my Windows servers, and my Windows desktops in real time.... any sort of animal exist?

Just installed Ubuntu 10.04 on my Acer laptop last night. I wasn't able to surf the net at first but after searching these forums, managed to get it right (changed setting in firefox). I was able to use update manager and the software program ok (downloading and installing). I am using a adsl via wifi. Networked pcs and my NAS/samba work fine
My current problem is that while I can surf the net and download updates etc, I can't seem to get email and chat working, it just gives a timeout error for some reason.
I was wondering if anyone could be kind to me in providing exact variable to be set for ldpa server installtion.
I am currently installing ldap in linux Red Hat Enterprise Linux AS release 4 (Nahant Update 6) and i get teh following error mesage.
I tried settng exact variable by reffering to ~/doc/install/configure but in vain.
I have successfully installed Openldap and am able to authenticate to it, but I can not get the replication server operating correctly. I have followed all of the steps in doing so from this guide, [URL], but there are a few things i don't understand. when creating the consumer_sync.ldif file on the consumer server it says to replace ldap01.example.com to your server's hostname.
would this be the provider or consumer? My porvider is ldap@tech.local and my consumer is ldap-backup@tech.local.... so what one are they refurring to with the ldap01? And is there a way to push, or sync the two server manually? How do I know if they are backing up properly? How do I test?

this idea to me right now seems stupid and impractical so I'm also looking for solutions outside of this one. I'm creating a set of highly available servers. They currently utilize pacemaker to manage a shared IP address, apache management, mysql management and also drbd handling. They currently replicate, properly failover and run fine. However, this is a shared web hosting setup and everytime a new user is added to the system a username and password is created and the httpd.conf file is updated for their site. I need a way to replicate those changes to the other server. For httpd.conf I'm pretty sure I can just stick it on the apache drbd resource and create a symbolic link. However, for the passwd and shadow files that is not a realistic solution.
View 1 Replies View RelatedAfter moving a website folder on my local development machine to another drive, then moving it back, I got a 403 error. Most of this problem had probably to do with rights that got messed up. After deleting the code and restoring it from SVN, the rights seemed allright. The error stayed however.
