Keepalived compilation and installation

Compile and install keepalived

Install keepalived 1.2.6 first using source code

Cd/usr/local/src

Wget http://www.keepalived.org/software/keepalived-1.2.6.tar.gz

Tarzxf keepalived-1.2.6.tar.gz

Cdkeepalived-1.2.6

. / configure--prefix=/usr/local/keepalived

Make

Makeinstall

If the keepalived you set up is installed to / usr/local/keepalived, all configuration files are located in this directory. One problem I haven't figured out is that Linux always installs programs in the / usr/local directory by default, and all programs share the / usr/local/sbin directory. This has an impact on some people's operating habits. Why not consider using a separate directory for each software?

1. Create a service startup script to control it using the service command

Cp / usr/local/keepalived/etc/rc.d/init.d/keepalived / etc/init.d/keepalived

Chmod+x / etc/init.d/keepalived

Because we use a non-default path (/ usr/local) to install keepalived, we need to modify several paths to ensure that keepalived can start properly. The files that need to be modified are as follows:

two。 Modify / etc/init.d/keepalived, look for about 15 lines of. / etc/sysconfig/keepalived, change to:

. / usr/local/keepalived/etc/sysconfig/keepalived, that is, point to the correct file location

Also add the following under the above line (import the path of the keepavlied main program into the environment variable PATH):

PATH= "$PATH:/usr/local/keepalived/sbin"

ExportPATH

3. Modify the / usr/local/keepalived/etc/sysconfig/keepalived file to set the correct service startup parameters

KEEPALIVED_OPTIONS= "- D-f/usr/local/keepalived/etc/keepalived/keepalived.conf"

4. After the above modifications, the basic installation of keepalived can be completed, and start the test:

Service keepalived restart

5. Don't forget to set this service to boot
