Redis 自动化脚本安装方案
以下是 Redis 自动化脚本安装方案，支持多个版本和安装方式：
📦 Redis 一键安装脚本
脚本功能：
✅ 支持 Redis 6.x/7.x 版本选择
✅ 自动编译安装和系统包安装
✅ 系统服务配置和开机自启
✅ 安全配置和密码认证
✅ 性能优化配置
✅ 远程访问配置
🔧 完整安装脚本

🚀 快速安装方式
方法1：一键脚本安装
# 下载脚本
wget -O install-redis.sh https://raw.githubusercontent.com/example/install-redis/master/install-redis.sh
# 添加执行权限
chmod +x install-redis.sh
# 运行安装
sudo ./install-redis.sh方法2：各系统快速安装
# Ubuntu/Debian
sudo apt update && sudo apt install -y redis-server redis-tools
sudo systemctl enable redis-server && sudo systemctl start redis-server
# CentOS/RHEL/Amazon Linux
sudo yum install -y epel-release
sudo yum install -y redis
sudo systemctl enable redis && sudo systemctl start redis
# 检查状态
redis-cli ping⚙️ 常用管理命令
#查看Redis服务进行
ps -ef | grep redis
# 服务管理
sudo systemctl start redis # 启动
sudo systemctl stop redis # 停止
sudo systemctl restart redis # 重启
sudo systemctl status redis # 查看状态
sudo systemctl enable redis # 设置开机自启
# Redis CLI 操作
redis-cli -h 127.0.0.1 -p 6379 -a <password> # 连接Redis
redis-cli ping # 测试连接
redis-cli info # 查看信息
redis-cli info memory # 查看内存信息
redis-cli info clients # 查看客户端信息
redis-cli monitor # 监控命令
# 数据操作
redis-cli set key "value" # 设置键值
redis-cli get key # 获取值
redis-cli keys "*" # 查看所有键
redis-cli flushdb # 清空当前数据库
redis-cli flushall # 清空所有数据库
# 删除
INSTALL_DIR="/usr/local/redis"
DATA_DIR="/var/lib/redis"
LOG_DIR="/var/log/redis"
sudo find / -name "*redis*" # 查找Redis所有相关文件
sudo rm -rf /usr/local/redis # 删除Redis安装目录
sudo rm -rf /var/lib/redis # 删除Redis数据目录
sudo rm -rf /etc/redis # 删除Redis配置文件
sudo rm -rf /var/log/redis # 删除Redis日志目录

修改监听地址和端口
sudo vi /usr/local/redis/etc/redis.conf
# 修改 bind 和 port 配置配置内存策略
# 在配置文件中修改
maxmemory 2gb
maxmemory-policy allkeys-lru启用AOF持久化
appendonly yes
appendfsync everysec配置主从复制
在从节点配置文件中添加：
replicaof <master-ip> <master-port>
masterauth <master-password>🔍 安装验证和测试
# 检查服务状态
sudo systemctl status redis# 检查端口监听
netstat -tulpn | grep 6379
ss -tulpn | grep 6379# 测试连接
redis-cli -h 127.0.0.1 -p 6379 -a <password> ping# 性能测试
redis-benchmark -h 127.0.0.1 -p 6379 -a <password> -q -n 100000# 查看统计信息
redis-cli -h 127.0.0.1 -p 6379 -a <password> info# 创建测试数据
for i in {1..1000}; doredis-cli -h 127.0.0.1 -p 6379 -a <password> set "key:$i" "value:$i"
done🔍 客户端连接测试
这个脚本提供了完整的Redis安装方案，包括安全配置、性能优化和集群支持，适合生产环境使用！
