keepalived的weight _Keepalived

白日放歌须纵酒，青春作伴好还乡。这篇文章主要讲述keepalived的weight相关的知识，希望能为你提供帮助。
1.weight 大于0
如果脚本监测失败，优先级不变，如果成功，优先级增加，如果后续监测失败，则优先级在增加的基础上回退，这个weight不会持续增加或减小，只会存在两个值
2.weight 小于0
如果脚本监测失败，优先级降低，如果成功，优先级不变，这个weight不会持续增加或减小，只会存在两个值

【keepalived的weight】另外，keepalived启动时，不论rise和fall的设置的是多少，首次监测脚本，都会根据上面的原则调整，后续的调整则要只有在进入fall和rise到达之后才会调整

Thedefaultweight equals 0, which means that any VRRP instance moni-
toring the script will transition to the fault state after < fall>
consecutivefailuresof the script. After that, < rise> consecu-
tive successes will cause VRRP instancestoleavethefaultstate,
unlessthey are also in the fault state due to other scripts or inter-
faces that they are tracking.

< weight> to the priority of all VRRP instances which monitor it.
On the opposite, a negative weight will be subtracted from theinitial
priority in case of < fall> failures.
