主节点ip:192.168.3.122,备节点ip:192.168.3.123
主节点配置如下:
! Configuration file for keepalived
global_defs {
notification_email {
admin@wf.com
}
notification_email_from admin@wf.com
smtp_server 127.0.0.1
smtp_connect_timeout 30
router_id LVS_DEVEL
}
#监控huawei-grpc
vrrp_script chk_nginx {
script "/etc/keepalived/script/monitor_nginx.sh"
interval 2
weight 2
}
vrrp_instance VI_1 {
state MASTER #主从设置
interface em1 #网卡名
virtual_router_id 1
mcast_src_ip 192.168.3.122 #本机ip
priority 100 #从机小于主机
advert_int 1
authentication {
auth_type PASS
auth_pass chtopnet
}
virtual_ipaddress {
192.168.3.120 #VIP 的IP
}
#track_script {
#chk_nginx
#}
}
virtual_server 192.168.3.120 50051 {
delay_loop 6
lb_algo rr
lb_kind DR
persistence_timeout 50
protocol TCP
real_server 192.168.3.122 50051 {
weight 3
TCP_CHECK {
connect_timeout 10
retry 3
delay_before_retry 3
connect_port 50051
}
}
real_server 192.168.3.123 50051 {
weight 3
TCP_CHECK {
connect_timeout 10
nb_get_retry 3
delay_before_retry 3
connect_port 50051
}
}
}
备节点配置如下:
