大家好。我在配置keepalived和haproxy的时候遇到脑裂的问题,还请大家帮助我分析一下,谢谢。我的环境信息如下:
一共两台虚拟机,是同个一共模板复制出来的(我怀疑问题出在这里)。
主机IP:192.168.1.136
备机IP:192.168.1.135
VIP:192.168.1.118
主机的keepalived的配置如下:
global_defs {
notification_email {
root
}
notification_email_from root
smtp_server 192.168.0.55
smtp_connect_timeout 30
router_id HAproxy
}
vrrp_script chk_haproxy {
script "/opt/check_haproxy.sh"
interval 2
weight 2
}
vrrp_instance HAproxy1 {
state MASTER #标示状态为MASTER 备份机为BACKUP
interface eth0
virtual_router_id 51
priority 100 #MASTER权重为100,BACKUP权重为90
advert_int 1
authentication {
auth_type PASS #主从服务器验证方式
auth_pass 1111
}
track_interface { # 监控的接口
eth0
eth1
}
virtual_ipaddress {
192.168.1.118/24 dev eth0
}
track_script {
chk_haproxy ### 执行监控的服务
}
}
备机的keepalived的配置如下:
global_defs {
notification_email {
root
}
notification_email_from root
smtp_server 192.168.0.55
smtp_connect_timeout 30
router_id HAproxy
}
vrrp_script chk_haproxy {
script "/opt/check_haproxy.sh"
interval 2
weight 2
}
vrrp_instance HAproxy1 {
state BACKUP #标示状态为MASTER 备份机为BACKUP
#interface eth0:1
#interface eth0.1
interface eth0
virtual_router_id 51
priority 90 #MASTER权重为100,BACKUP权重为90
advert_int 1
authentication {
auth_type PASS #主从服务器验证方式
auth_pass 1111
}
track_interface { # 监控的接口
eth0
eth1
}
virtual_ipaddress {
192.168.1.118/24 dev eth0
}
track_script {
chk_haproxy ### 执行监控的服务
}
}
主备机网络是通的。
主备机操作系统是CentOS6.1,keepalived的版本是Keepalived v1.2.15。
在我的测试环境中,我用上面的配置在主备机分别启动keepalived以后,发现备机先进入BACKUP在转换到MASTER模式。如下为日志
