1、下载程序包
wget https://download.redis.io/redis-stable.tar.gz
2、解压、编译安装
tar -xf redis-stable.tar.gz cd redis-stable make
3、配置
# 内核参考优化
echo 'vm.overcommit_memory = 1' >> /etc/sysctl.conf
sysctl -p
# 创建数据目录并配置执行文件
mkdir -p /usr/local/redis/{bin,etc,var}
cp src/{redis-benchmark,redis-check-aof,redis-check-rdb,redis-cli,redis-sentinel,redis-server} /usr/local/redis/bin/
ln -s /usr/local/redis/bin/* /usr/local/bin/
# 拷贝配置文件
cp redis.conf /usr/local/redis/etc/
# 创建用户并授权
useradd -M -s /sbin/nologin redis
chown -R redis:redis /usr/local/redis/{var,etc}
# 修改部分的配置文件
# vim /usr/local/redis/etc/redis.conf
...
bind 0.0.0.0
timeout 600
daemonize yes
pidfile /var/run/redis/redis.pid
dir /usr/local/redis/var
requirepass password
maxmemory 4G
maxmemory-policy volatile-lru
appendonly yes
...
4、服务配置
