saup007：双主MySQL配置Keepalived，2个角色都为BACKUP,
A节点：
vrrp_script chk_mysql_server {
#script "/opt/keepalived/script/chk_mysql_server.sh"
script "killall -0 mysqld"
interval 30 # 检测时间为30s
weight 21
}
vrrp_instance VI_1 {
state BACKUP
interface eth1
virtual_router_id 59
priority 100
advert_int 1
nopreempt
#mcas_src_ip 172.19.1.201
authentication {
auth_type PASS
auth_pass 1111
}
notify_master "/opt/keepalived/script/master.sh"
notify_backup "/opt/keepalived/script/backup.sh"
notify_fault "/opt/keepalived/script/fault.sh"
notify_stop "/opt/keepalived/script/stop.sh"
track_script {
chk_mysql_server
}
virtual_ipaddress {
172.19.1.249/24 dev eth1 scope global label eth1:0
}
}
B节点：
priority 90
#nopreempt
当停掉A的MySQL，正常切换到B，当把A MySQL启来后，vip依然在B，这个符合逻辑，但把A MySQL启来后，再去停掉B MySQL，VIP却没有飘移到A上，why？
vrrp_script chk_mysql_server {
#script "/opt/keepalived/script/chk_mysql_server.sh"
script "killall -0 mysqld"
interval 30 # 检测时间为30s
weight 21
}
这里面的权重设置有问题，修改weight值
