一、下載redis

## download
wget https://download.redis.io/releases/redis-6.2.5.tar.gz
tar -xzvf  redis-6.2.5.tar.gz  -C /usr/local cd /usr/local 
mv redis-4.0.11 redis 
cd redis 
make
make PREFIX=/usr/local/redis installenv path 
在/etc/profile檔案尾部增加redis環境變數，並執行
export REDIS_HOME=/usr/local/redis
export PATH=$PATH:$REDIS_HOME/src
最後執行source 
 
/etc/profile使之生效 

二、配置

master.conf 主庫

masterauth mypwd
requirepass mypwd
protected-mode yes
bind 192.168.5.116 #區域網ip或者外網ip
daemonize yes
logfile /codeyuguo/redis/redis.log
appendonly yes
dir /codeyuguo/redis

sentinel.conf 哨兵配置

sentinel monitor mymaster 192.168.5.116 6379 1
sentinel auth-pass mymaster mypwd
sentinel down
 
-after-milliseconds mymaster 15000
sentinel parallel-syncs mymaster 1
sentinel failover-timeout mymaster 80000
bind 192.168.5.116
protected-mode yes
daemonize yes
logfile /codeyuguo/redis/sentinel.log
appendonly yes
dir /codeyuguo/redis

slave.conf 從庫配置

masterauth mypwd
requirepass mypwd
protected-mode yes
bind 
 
192.168.6.49
slaveof 192.168.5.116 6379
daemonize yes
logfile /codeyuguo/redis/redis.log

三、注意事項

1. 在建立目錄/codeyuguo/redis/conf，並在conf資料夾下建立上述maser.conf/slave.conf/sentinel.conf三個配置檔案
2. 總共3臺節點,一個節點上配置主庫和哨兵，其他兩個節點上配置從庫和哨兵
1. 配置主庫 執行 redis-server /codeyuguo/redis/conf/master.conf
2. 配置從庫執行 redis-server /codeyuguo/redis/conf/slave.conf
3. 配置哨兵 執行 redis-sentinel /codeyuguo/redis/conf/sentinel.conf

四、附錄

4. 1 redis啟動指令碼

#
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.

     exit 1
