三、keepalived配置文件
Master的配置文件：
! Configuration File for keepalived
global_defs {
router_id LVS_1
}
vrrp_script chk_haproxy {
script "/etc/keepalived/check_haproxy.sh"
interval 2
weight 2
}
vrrp_instance VI_1 {
state MASTER
priority 99
advert_int 1
virtual_router_id 50
garp_master_delay 1
interface eth0
authentication {
auth_type PASS
auth_pass Kxiaokk345Pix
}
track_interface {
eth0
}
virtual_ipaddress {
192.168.1.100
}
track_script {
chk_haproxy
}
notify_master "/etc/keepalived/mailnotify.py master"
notify_backup "/etc/keepalived/mailnotify.py backup"
notify_fault "/etc/keepalived/mailnotify.py fault"
}
Slave的配置文件
! Configuration File for keepalived
global_defs {
router_id LVS_2
}
vrrp_script chk_haproxy {
script "/etc/keepalived/check_haproxy.sh"
interval 5
weight 2
}
vrrp_instance VI_1 {
state BACKUP
priority 96
advert_int 1
virtual_router_id 50
garp_master_delay 1
interface eth0
authentication {
auth_type PASS
auth_pass Kxiaokk345Pix
}
track_interface {
eth0
}
virtual_ipaddress {
192.168.1.100
}
track_script {
chk_haproxy
}
notify_master "/etc/keepalived/mailnotify.py master"
notify_backup "/etc/keepalived/mailnotify.py backup"
notify_fault "/etc/keepalived/mailnotify.py fault"
}
