redis 6.2.5一主两从3哨兵配置

一、下载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文件尾部增加redis环境变量，并执行
export REDIS_HOME=/usr/local/redis
export PATH=$PATH:$REDIS_HOME/src
最后执行source /etc/profile使之生效 

 

　　

二、配置

master.conf 主库

masterauth mypwd
requirepass mypwd
protected-mode yes
bind 192.168.5.116 #局域网ip或者外网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 从库配置

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、注意事项

1. 在创建目录/codeyuguo/redis/conf，并在conf文件夹下创建上述maser.conf/slave.conf/sentinel.conf三个配置文件
2. 总共3台节点,一个节点上配置主库和哨兵，其他两个节点上配置从库和哨兵
1. 配置主库 执行 redis-server /codeyuguo/redis/conf/master.conf
2. 配置从库执行 redis-server /codeyuguo/redis/conf/slave.conf
3. 配置哨兵 执行 redis-sentinel /codeyuguo/redis/conf/sentinel.conf

四、附录

4. 1 redis启动脚本
