LVS
|
pulse
|
This is the controlling process which starts all other daemons related to LVS routers. At boot time, the daemon is started by the /etc/rc.d/init.d/pulse script. It then reads the configuration file /etc/sysconfig/ha/lvs.cf. On the active LVS router, pulse starts the LVS daemon. On the backup router, pulse determines the health of the active router by executing a simple heartbeat at a user-configurable interval. If the active LVS router fails to respond after a user-configurable interval, it initiates failover. During failover, pulse on the backup LVS router instructs the pulse daemon on the active LVS router to shut down all LVS services, starts the send_arp program to reassign the floating IP addresses to the backup LVS router's MAC address, and starts the lvs daemon.
|
| |
lvsd
|
The lvs daemon runs on the active LVS router once called by pulse. It reads the configuration file /etc/sysconfig/ha/lvs.cf, calls the ipvsadm utility to build and maintain the IPVS routing table, and assigns a nanny process for each configured LVS service. If nanny reports a real server is down, lvs instructs the ipvsadm utility to remove the real server from the IPVS routing table.
|
| |
ipvsadm
|
This service updates the IPVS routing table in the kernel. The lvs daemon sets up and administers LVS by calling ipvsadm to add, change, or delete entries in the IPVS routing table.
|
| |
nanny
|
The nanny monitoring daemon runs on the active LVS router. Through this daemon, the active LVS router determines the health of each real server and, optionally, monitors its workload. A separate process runs for each service defined on each real server.
|
| |
lvs.cf
|
This is the LVS configuration file. The full path for the file is /etc/sysconfig/ha/lvs.cf. Directly or indirectly, all daemons get their configuration information from this file.
|
| |
Piranha Configuration Tool
|
This is the Web-based tool for monitoring, configuring, and administering LVS. This is the default tool to maintain the /etc/sysconfig/ha/lvs.cf LVS configuration file.
|
| |
send_arp
|
This program sends out ARP broadcasts when the floating IP address changes from one node to another during failover.
|
