redis系列-redis哨兵安裝步驟

Redis哨兵安裝步驟

－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－

以前的redis6379.conf的配置不變，作爲主節佔，而且複製出兩個配置文件redis6380.conf， redis6381.conf，這兩個配置文件啓動後的redis作爲6379節點的從節點。:

 

注意：redis6380.conf和redis6381.conf 加上slaveof 127.0.0.1 6379

        修改 requirepass 12345678 ,註釋掉bind 127.0.0.1, 加上masterauth 12345678

 

redis sentinel哨兵機制配置(也是3個節點)：

   /usr/local/bin/conf/sentinel_26379.conf 

   /usr/local/bin/conf/sentinel_26380.conf

   /usr/local/bin/conf/sentinel_26381.conf

將三個文件的端口改爲: 26379   26380   26381

而後：sentinel monitor mymaster 127.0.0.1 6379 2  //監聽主節點6379

          sentinel auth-pass mymaster 12345678     //鏈接主節點時的密碼

三個配置除端口外，其它同樣。

啓動sentinel服務:

            ./redis-sentinel conf/sentinel_26379.conf &

            ./redis-sentinel conf/sentinel_26380.conf &

            ./redis-sentinel conf/sentinel_26381.conf &

 

 

殺掉進程

ps -ef|grep redis-server |grep 6379 | grep -v grep | awk '{print $2}' | xargs kill -9
ps -ef|grep redis-server |grep 6380 | grep -v grep | awk '{print $2}' | xargs kill -9
ps -ef|grep redis-server |grep 6381 | grep -v grep | awk '{print $2}' | xargs kill -9
ps -ef|grep redis-sentinel |grep 26379 | grep -v grep | awk '{print $2}' | xargs kill -9
ps -ef|grep redis-sentinel |grep 26380 | grep -v grep | awk '{print $2}' | xargs kill -9
ps -ef|grep redis-sentinel |grep 26381 | grep -v grep | awk '{print $2}' | xargs kill -9

啓動進程
../redis-server redis6379.conf &
../redis-server redis6380.conf &
../redis-server redis6381.conf &
../redis-sentinel sentinel_26379.conf &
../redis-sentinel sentinel_26380.conf &
../redis-sentinel sentinel_26381.conf &

 

測試：

kill -9 6379  殺掉6379的redis服務

看日誌是分配6380 仍是6381作爲主節點，當6379服務再啓動時，已變成從節點

若是6380升級爲主節點:進入6380>info replication     能夠看到role:master

打開sentinel_26379.conf等三個配置，sentinel monitor mymaster 127.0.0.1 6380 2

外部應用鏈接sentinel時， sentinel.conf的protected-mode no改爲no

./redis-cli -p 26380 shutdown //關閉
