Keepalived is a highly available solution to prevent spof.

First download:

Cd/usr

Wget http://www.keepalived.org/software/keepalived-1.2.7.tar.gz

Decompress:

Tar zxvf keepalived-1.2.7.tar.gz

Several libraries need to be installed before Compilation

1. Apt-get install libssl-dev
2. Apt-get install openssl
3. Apt-get install libpopt-dev

Then run

1. ./Configure -- prefix =/usr

The following result is displayed:

1. Keepalived configuration
2. ------------------------
3. Keepalived version: 1.2.7
4. Compiler: gcc
5. Compiler flags:-g-O2
6. Extra Lib:-lpopt-lssl-lcrypto
7. Use IPVS Framework: Yes
8. S sync daemon support: Yes
9. S use libnl: No
10. Use VRRP Framework: Yes
11. Use vrrp vmac: Yes
12. SNMP support: No
13. Use Debug flags: No

Compile:

Make

Make install

Install the program in the following directories:

/Usr/sbin contains the executable program keepalived.

/Usr/etc/keepalived/contains the configuration file and example

/Usr/etc/rc. d/init. d/keepalived is a service script file that can be copied to the/etc/init. d directory.

Three modifications:

1. #./Etc/rc. d/init. d/functions
2. ./Lib/lsb/init-functions

1. #./Etc/sysconfig/keepalived
2. ./Usr/etc/sysconfig/keepalived

Because Linux except RedHat does not have the above two directories.

You must modify the following parameters and replace $ {...} with start.

1. Start (){
2. Echo-n $ "Starting $ prog :"
3. # Daemon keepalived $ {KEEPALIVED_OPTIONS}
4. Daemon keepalived start
5. RETVAL =$?
6. Echo
7. [$ RETVAL-eq 0] & touch/var/lock/subsys/$ prog
8. }

Create a directory

1. Mkdir-p/var/lock/subsys

Now set as System Service

1. Update-rc.d keepalived default

Install the daemon service.

Apt-get install daemon

Now, we can start it normally.

Service keepalived start

Disable

Service keepalived stop
