一、安裝配置
1. redis安裝
參考地址：
https://www.cnblogs.com/heqiuyong/p/10463334.html
安裝路徑： /usr/local/redis
配置|命令路徑：/usr/local/redis/bin
資料|日誌路徑：/data/redis
//連線客戶端
./redis-cli -p 9736
redis.conf修改內容
dir /data/redis bind 0.0.0.0 port 9736 logfile /data/redis/redis.log appendonly yes
2. 每日備份
參考：
https://blog.csdn.net/Junetest/article/details/104796142/
指令碼地址：/data/redis/backup.sh
//1.編輯指令碼 cd /data/redis vim backup.sh #! /bin/bash PATH=/usr/local/redis/bin:$PATH redis-cli -p 9736 bgsave date=$(date +"%Y%m%d") cp /data/redis/dump.rdb /data/redis/backup/dump$date.rdb echo " 備份完成!" DAYS=7 find /data/redis/backup/ -mtime +$DAYS -delete #刪除7天前的備份檔案 echo "刪除7天前資料備份完成！" chmod +x backup.sh //2.新增定時任務 crontab -e //每天凌晨兩點半備份 30 2 * * * sh /data/redis/backup.sh crontab -l
二、操作
1. 常用系統命令
cd /usr/local/redis/bin/ // 1.檢視redis狀態 ./redis-cli -p 9736 --stat // 2.檢視統計最大鍵 ./redis-cli --bigkeys -p 9736 // 3.監控redis操作 ./redis-cli -p 9736 monitor // 4.延遲測試 ./redis-cli -p 9736 --latency // 5.歷史延遲 ./redis-cli -p 9736 --latency-history // 6.資料備份 https://blog.csdn.net/rentian1/article/details/93845092 ./redis-cli -p 9736 --rdb /data/redis/backup/dump20201104.rdb
2. 效能測試
