1. 目录规划

###配置文件、日志、pid目录
mkdir -p /usr/local/redis/{conf,logs,pid}

###redis数据目录
mkdir -p /data/redis

2. 安装Redis

###获取redis源码包
wget https://download.redis.io/releases/redis-6.2.6.tar.gz

###解压
tar xf redis-6.2.6.tar.gz -C /usr/local/redis

###安装
cd /usr/local/redis/redis-6.2.6
make && make install

3. 创建redis配置文件

###备份旧的redis.conf
mv /usr/local/redis/redis-6.2.6/redis.conf{,_bak}

###创建新的redis.conf

4. systemd管理redis

cat >/etc/systemd/system/redis.service <

systemctl start redis.service  && systemctl enable redis.service
systemctl status redis.service
