The scripts featured in the community section of zimbra’s website are quite elaborate.
Personally – I like things simple:
#!/bin/sh
mailhost=”atmx02″;
date
ssh $mailhost “service zimbra stop”
rsync -av -e ssh $mailhost:/opt/zimbra /data/backup
ssh $mailhost “service zimbra start”
date
Here is how you enable 802.x tagging on your Centos host
cat /etc/sysconfig/network-scripts/ifcfg-vlan100

It’s February 2010. Far out time flies.
The example shows group dialing on the inbound number, to 2 SIP clients as well as a Cisco VoIP handset.
Where 12345678 is your mynetfone account number.
extensions.conf:
[myfone-inbound]
exten => 12345678,1,Dial(SIP/6666,30)
exten => 12345678,2,Congestion
exten => 12345678,102,Busy
[default]
exten => 12345678,1,Dial(SIP/6666&SIP/6667&SCCP/6668,30)
exten => 12345678,2,Congestion
exten => 12345678,102,Busy
sip.conf:

dont forget NAT and rtp.conf, forward these UDP ports onto your Asterisk server

restart mysql on the master:
service mysqld restart
stop mysql on the slave:
service mysqld stop
on the master grant privileges to the slave:
GRANT REPLICATION SLAVE ON *.* TO ‘user’@'host’ IDENTIFIED BY ‘pass’;
on the master lock the database:
FLUSH TABLES WITH READ LOCK;
on the master take note of the current position and log file name:
SHOW MASTER STATUS \G
copy the data from the master to the slave
rsync -e ssh -av /var/lib/mysql/ root@host:/var/lib/mysql
on the master unlock the database:
UNLOCK TABLES;
fire up mysql on the slave:
service mysqld start
on the slave configure the master:
CHANGE MASTER TO
MASTER_HOST=’master_host’,
MASTER_USER=’user’,
MASTER_PASSWORD=’pass’,
MASTER_LOG_FILE=’log_file_name’,
MASTER_LOG_POS=log_position;
on the slave fire up the replication:
SLAVE START;
check on the slave status:
SHOW SLAVE STATUS \G
rejoice.
test it out – create tables, drop a database, do whatever you like on the master and watch the magic on the slave.
