CentOS 7.9 上安装 Redis 6.2.14

在 CentOS 7.9 上安装 Redis 6.2.14 到 /usr/local/redis
安装依赖

yum install -y epel-release
yum install -y gcc make tcl

下载并编译 Redis
官网下也行

cd /usr/local/src
wget https://download.redis.io/releases/redis-6.2.14.tar.gz
tar xzf redis-6.2.14.tar.gz
cd redis-6.2.14

# 编译安装到指定目录
make PREFIX=/usr/local/redis install

创建配置文件和数据目录

mkdir -p /usr/local/redis/{conf,data,logs}
cp /usr/local/src/redis-6.2.14/redis.conf /usr/local/redis/conf/

修改配置文件

vi /usr/local/redis/conf/redis.conf

修改以下关键配置：

• daemonize yes
• bind 127.0.0.1 # 生产环境改为服务器IP
  bind 0.0.0.0 # 允许远程访问（生产环境建议限制IP）
  或者注释掉
• dir /usr/local/redis/data
• logfile "/usr/local/redis/logs/redis.log"
• requirepass yourpassword # 设置访问密码（可选）

创建 systemd 服务

vi /etc/systemd/system/redis.service
