Redis单点一键部署脚本

maxmemory需要按需修改

#!/bin/bash

# 安装依赖
apt update
apt install -y gcc make pkg-config tcl

# 创建安装目录
mkdir -p /data/redis
cd /data/redis

# 修改内核参数允许redis进行内存申请
echo "vm.overcommit_memory = 1" >> /etc/sysctl.conf
sysctl -p

# 下载并编译Redis
wget https://download.redis.io/releases/redis-7.2.4.tar.gz
tar xzf redis-7.2.4.tar.gz
cd redis-7.2.4
make

# 安装Redis
make install

# 创建必要的目录
mkdir -p /data/redis/conf
mkdir -p /data/redis/log
mkdir -p /data/redis/data

# 创建redis配置文件
cat > /data/redis/conf/redis.conf << 'EOF'
# 基本配置
bind 0.0.0.0
port 6379
daemonize yes
pidfile /data/redis/redis.pid
dir /data/redis/data
logfile /data/redis/log/redis.log
# 安全配置
protected-mode yes
maxmemory-policy volatile-lru
maxmemory 5120M
requirepass xxxxxxx
# RDB配置
save 60 1
save 300 10
save 60 10000
dbfilename dump.rdb
rdbcompression yes
rdb-save-incremental-fsync yes
# 禁用AOF
appendonly no
