配置 redis 启动、停止脚步 redis.sh
#!/bin/bash
case $1 in
"start")
if(ps -ef | grep redis-server | grep -v grep > /dev/null); then
echo "Redis is running!"
else
src/redis-server redis.conf
fi
;;
"stop")
if(ps -ef | grep redis-server | grep -v grep > /dev/null); then
kill -9 `ps -ef | grep redis-server | grep -v grep | awk ‘{print $2}‘`
else
echo "Redis is not running!"
fi
;;
"restart")
if(ps -ef | grep redis-server | grep -v grep > /dev/null); then
kill -9 `ps -ef | grep redis-server | grep -v grep | awk ‘{print $2}‘`
src/redis-server redis.conf
else
echo "Redis is not running!"
src/redis-server redis.conf
fi
;;
*)
echo "Input Error! Example: sh redis.sh start | stop | restart"
;;
esac
配置 sentinel 启动、停止脚步 sentinel.sh
#!/bin/bash
case $1 in

启动redis实例
sh redis.sh start
启动sentinel实例
sh sentinel.sh start
简单测试
set key1 value1
get key1
检查集群状态
info
测试 spring boot 连接 redis-sentinel,添加以下配置
redis:
database: 0
sentinel:
master: mymaster
nodes: 192.168.1.224:26379,192.168.1.225:26379,192.168.1.226:26379
