參考官網
https://redis.io/download/
https://redis.io/docs/getting-started/installation/install-redis-from-source/
下載最新穩定版，當前是 7.0.0
wget https://download.redis.io/redis-stable.tar.gz
tar zxf /usr/local/src/redis-stable.tar.gz -C /usr/local/
安裝編譯工具
yum install gcc-c++ make
cd /usr/local/redis-stable && make
至此，redis二進制文件都已生成，且在本目錄下，具備可遷移性
# 如果要安裝二進制文件到系統目錄/usr/local/bin，則執行以下安裝命令，否則忽略
make install
調整目錄結構，使其更直觀
mkdir etc bin
備份原始配置，並修改配置
cp redis.conf etc/redis_default.conf
grep -vP '^#|^$' > etc/redis.conf
## 修改配置
# tcp-keepalive 默認300s，可改爲 60s
tcp-keepalive 60
# 單機多實例時，需分別指定不同的pid文件
pidfile /var/run/redis_6379.pid
# 日誌
logfile /usr/local/redis-stable/logs/redis.log
# 實例目錄
dir /usr/local/redis-stable/
## 更多配置修改，參考原始配置和官方網站
# 單機多實例時，建議以不同目錄區分實例，如 redis_6379、redis_6380 等。
cp src/mkreleasehdr.sh bin/
cp src/redis-benchmark bin/
cp src/redis-check-aof bin/
cp src/redis-check-rdb bin/
cp src/redis-cli bin/
cp src/redis-sentinel bin/
cp src/redis-server bin/
cp src/redis-trib.rb bin/
## 也可以使用自帶工具初始化，指定目錄和配置、端口，會將二進制文件和配置文件部署到自定義目錄：
sh utils/install_server.sh
## 啓動，並檢查日誌
