I have been scripting Inotify to work as file replication.It works very well for casual use when editing or uploading files. But I have to make sure it stands up against a "tar bomb" when we install a new package. EG: tar -xzf really_big_php_project.tar.gz
Code:
#!/bin/sh
# get the current path

I am running shell command through C program using system() routine.
I am executing "opcontrol --status" an executable using the this routine and I get the following error. access: unix error (2) No such file or directory
But when I give the complete path to the executable it runs perfectly.
The executable is installed in "/usr/local/bin/" And the path variable has this path.
I am using Debian as mail server and proxy server. I need to configure one backup server for the same. Mainly I need to replicate/sync the files on both machines. So I can avoid the failure time.

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?
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 7 Replies View RelatedI'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 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 had Configured a MySQL Master-Slave replication.It seems that the binary logs steals so much space of My storage.
i.)My Master
show master status;
+------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000144 | 475823 | | |
+------------------+----------+--------------+------------------+
1 row in set (0.00 sec)
ii.)My Slave.
mysql> SHOW SLAVE STATUSG;
*************************** 1. row ***************************
Slave_IO_State: Waiting for master to send event

If i remove all binary files up tp mysql-bin.000144 using "PURGE",will it affect my existing database/any data loss.
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.

-> MASTER_HOST='192.168.1.220'
-> MASTER_USER='repl'

I have made a backupscript that simply copy files to an external harddisk with the command cp -a.
Before the backup script start I'll mount the external harddisk with mount /dev/sda1 /mnt/USB/backup. And after the script the external harddisk will be unmounted.
This all works great. But when the user is forgotten his external device the script is written the files to the system partition and that is a big problem.I've seen a lot of backup scripts who has the same problem.
Can I build in some routine that is the mounting is not working that the script is stopping?
Or are there some better ideas to avoid this?
When doing a routine update to GRUB, it asked me what drive/partition I want it installed on.

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?
