Codis3.2集群HA高可用方案

Codis高可用方案官方推薦使用Sentinel

Redis 本身就是最終一致性的。Master 掛了，Promote Slave 成為新的 Master 需要時(shí)間（測試15秒內(nèi)）。其實(shí) Sentinel 就是這個(gè)邏輯。Codis3.2 自己沒有實(shí)現(xiàn) HA，而是直接依賴 Sentinel 的。

注意事項(xiàng)：

Sentinel需要使用原生的Redis-server，版本要等于或高于Codis3.2里面的3.2.8版本， 這里是在Redis3.2.9的下配置測試的，另外Protected-mode no這個(gè)保護(hù)模式需要關(guān)閉，Sentinel.conf默認(rèn)配置不需要寫主從關(guān)系，Codif-fe界面SYNC會(huì)讀取主從關(guān)系。

1，每個(gè) Group 前面的 SYNC 是刷 group 所涉及到的 Slot 的路由表給 Proxy 的，包含主從關(guān)系。

2，而 Sentinel 前面的 SYNC 是給所有 Sentinel 刷配置的，同時(shí)把 Sentinel 列表刷給每個(gè) Proxy。所以只要在集群搭建完成之后，或者每次添加、刪除 Redis server 之后（穩(wěn)定之后） ，在 Sentinel 下面點(diǎn)一次 SYNC 即可。

3，Codis3.2 的只解決了并發(fā)遷移＋異步遷移問題。不會(huì)去做 HA 有關(guān)的工作。所以在 3.2 下解決問題的話， Sentinel 就足夠了，而且只能用 Sentinel。Sentinel 負(fù)責(zé)的是 Group 內(nèi)的主從切換。

4，內(nèi)核優(yōu)化

echo never > /sys/kernel/mm/transparent_hugepage/enabled

sysctl vm.overcommit_memory=1

一，Codis集群架構(gòu)

192.168.188.120 codis120 codis-server? zookeeper sentinel

192.168.188.121 codis121 codis-server? zookeeper sentinel

192.168.188.122 codis122 codis-server? zookeeper sentinel

192.168.188.123 codis123 codis-server? codis-proxy? sentinel lvs

192.168.188.124 codis124 codis-server? codis-proxy? sentinel lvs

192.168.188.125 codis125? codis-server? codis-dashboard sentinel codis-fe

二，配置Codis-server

每臺(tái)虛擬機(jī)部署3個(gè)實(shí)例：6379、6380、6381，共18個(gè)實(shí)例

192.168.188.120:6379、6380、6381

192.168.188.121:6379、6380、6381

192.168.188.122:6379、6380、6381

192.168.188.123:6379、6380、6381

192.168.188.124:6379、6380、6381

192.168.188.125:6379、6380、6381

三，配置Group

設(shè)置好1主2從關(guān)系，共6組，注意主從從3個(gè)實(shí)例需要來自3臺(tái)虛擬機(jī)

Group1（主從從）

192.168.188.120:6379? 192.168.188.121:6380? 192.168.188.123:6381

Group2（主從從）

192.168.188.121:6379? 192.168.188.120:6380? 192.168.188.124:6381

Group3（主從從）

192.168.188.122:6379? 192.168.188.123:6380? 192.168.188.125:6381

Group4（主從從）

192.168.188.123:6379? 192.168.188.122:6380? 192.168.188.120:6381

Group5（主從從）

192.168.188.124:6379? 192.168.188.125:6380? 192.168.188.121:6381

Group6（主從從）

192.168.188.125:6379? 192.168.188.124:6380? 192.168.188.122:6381

四，配置Sentinel

需要配置6個(gè)Sentinel，沒臺(tái)虛擬機(jī)上1個(gè)

注意這個(gè)原生是在sentinel 的配置文件里配置，3.2.9的原生的sentinel配置下，另外protected-mode no這個(gè)保護(hù)模式需要關(guān)閉，sentinel.conf默認(rèn)配置不需要寫主從關(guān)系，Codif-fe界面SYNC會(huì)讀取主從關(guān)系。

1，配置信息

[root@codis120 config]# cat sentinel.conf |grep -Ev "^#|^$"

protected-mode no

port 26379

dir "/tmp"

2，啟動(dòng)entinel，多個(gè)Sentinel便于選舉和保證高可用

192.168.188.120:26379

192.168.188.120:26379

192.168.188.120:26379

192.168.188.120:26379

192.168.188.120:26379

192.168.188.120:26379

3，SYNC后通過日志查看哨兵記錄

五，Group內(nèi)主從切換測試

Group3測試

Group3（主從從）

192.168.188.122:6379? 192.168.188.123:6380? 192.168.188.125:6381

1，首先，停止192.168.188.122:6379

[root@codis122 admin]# /usr/local/codis/admin/codis-server-admin-6379.sh stop

/usr/local/codis/admin/../config/redis-6379.conf

stopping codis-server ...

STOPPED

2，檢測發(fā)現(xiàn)192.168.188.125:6381被選舉為主了，切換過程大概15秒內(nèi)

3，最后啟動(dòng)192.168.188.122:6379，變成了Group3的一個(gè)從
