Heartbeat dual-Machine hot backup

Objective: To realize the hot backup of samba, that is, when a machine fails, B machine can be replaced automatically.

Get ready:

A machine (master) ip:192.168.1.67

b Machine (prepared) ip:192.168.1.68

Operation:

A: Modify the/etc/hosts file of machine A and B

Vim/etc/hosts joins 192.168.1.67 Zxw and 192.168.1.68 zxw1

Three: Configure Heartbeat. Copy ha.cf,authkeys,haresources 3 files from the/usr/share/doc/heartbeat-3.0.4/directory to the/etc/ha.d/directory

Four: Edit the 3 files just copied under the/etc/ha.d/directory

1:vim Authkeys Remove #auth 3 and #3 MD5 hello! In front of the #. Such as:

2:vim Haresources joins Zxw 192.168.1.8/24/eth0:0 SMB on the last line

# (ZXW represents the hostname of the Lord, 192.168.1.8 represents a machine with a B-machine communication IP,SMB for the need to do high-availability services)

3:vim HA.CF Add the following:

Debugfile/var/log/ha-debug

Logfile/var/log/ha-log

Logfacility local0

KeepAlive 2

Deadtime 30

Warntime 10

Initdead 60

Udpport 694

Ucast eth0 192.168.1.68

Auto_failback on

Node Zxw

Node ZXW1

Ping 192.168.1.1

Respawn Hacluster/usr/lib64/heartbeat/ipfail

V: Open SMB and Heartbeat services

Service SMB Start

Service Heartbeat Start

B machine: Repeat steps two to five.

To prevent the SMBD service on a machine from stopping without automatically switching to B, create a new script on the A to monitor whether SMB is functioning properly.

The 1:vim smb.sh script is as follows:      

#!/bin/bash

#it ' s about to watch SMB ' s status

While:

Do

I= ' PS aux |grep smbd |grep-v "grep smbd" |wc-l '

if [$i = 0];then

Service Heartbeat Stop

Fi

Done

2:chmod smb.sh Change permissions for smb.sh

3: Put the smb.sh in the background to run./smb.sh &

4: Put SMB, heartbeat,smb.sh join boot to run, vim/etc/rc.d/rc.local join service heartbeat start, service SMB restart, bash /root/smb.sh &

The above can be achieved:

1: When a machine is down, B machine can replace it,

2: When a machine is back to normal, B machine automatically exits as a standby machine.

The build is complete.
