1、下载并编译安装Redis

mkdir -p /data/OA && cd /data/OA
wget https://download.redis.io/releases/redis-7.0.5.tar.gz
tar xzf redis-7.0.5.tar.gz
cd redis-7.0.5
make && make PREFIX=/data/OA/redis-7.0.5 install

2、创建专用目录结构

sudo mkdir -p /data/OA/redis-7.0.5/{etc,logs,data,run}
sudo chown -R $USER:$USER /data/OA/redis-7.0.5  # 临时授权当前用户

3、**配置文件设置

(1) 复制默认配置

cp redis.conf /data/OA/redis-7.0.5/etc/

(2) 关键配置修改（/data/OA/redis-7.0.5/etc/redis.conf）

bind 127.0.0.1                 # 生产环境按需修改
port 6378                      # 使用您的自定义端口
daemonize no                   # 必须设为 no
supervised systemd             # 启用 systemd 监管
dir /data/OA/redis-7.0.5/data  # 数据目录
logfile "/data/OA/redis-7.0.5/logs/redis.log"
pidfile "/data/OA/redis-7.0.5/run/redis.pid"
appendonly yes                 # 按需启用 AOF
maxclients 4064                # 适配当前 ulimit
requirepass *****          #配置redis密码(自定义)

4 、系统用户和权限

sudo useradd -r -s /bin/false redis
sudo chown -R redis:redis /data/OA/redis-7.0.5
sudo chmod 750 /data/OA/redis-7.0.5

5、系统资源调优

(1) 文件描述符限制

echo "redis soft nofile 10032" | sudo tee -a /etc/security/limits.conf
echo "redis hard nofile 10032" | sudo tee -a /etc/security/limits.conf

(2) 内存分配策略

echo "vm.overcommit_memory = 1" | sudo tee -a /etc/sysctl.conf
sudo sysctl -p

6、Systemd 服务配置

创建 /etc/systemd/system/redis.service：

[Unit]
Description=Redis Data Store
After=network.target

[Service]
User=redis
Group=redis
Type=simple
ExecStart=/data/OA/redis-7.0.5/bin/redis-server /data/OA/redis-7.0.5/etc/redis.conf
ExecStop=/data/OA/redis-7.0.5/bin/redis-cli -p 6378 shutdown
Restart=always
TimeoutStopSec=30
PIDFile=/data/OA/redis-7.0.5/run/redis.pid

[Install]
WantedBy=multi-user.target

7、**启动并验证服

sudo systemctl daemon-reload
sudo systemctl start redis
sudo systemctl enable redis

# 检查状态
systemctl status redis -l
journalctl -u redis -f

# 测试连接
/data/OA/redis-7.0.5/bin/redis-cli -p 6378 ping
