Centos7升级redis

说明

为了解决redis 4.x到5.x 主从复制漏洞修复将redis升级至6.x

实施

redis 编译安装

下载 redis 源码包

redis源码站

wget https://download.redis.io/releases/redis-6.2.9.tar.gz
tar -xf redis-6.2.9.tar.gz
pushd redis-6.2.9 > /dev/null

停止备份旧服务

systemctl stop redis
mv /usr/local/redis /usr/local/redis.old

编译 redis 安装

PREFIX用于指定安装目录

make PREFIX=/usr/local/redis install

mkdir -p /usr/local/redis/etc
mkdir -p  /usr/local/redis/var

cp redis.conf /usr/local/redis/etc/redis-template.conf
cp /usr/local/redis.old/etc/redis.conf /usr/local/redis/etc/
chown redis.redis -R  /usr/local/redis/

创建 redis 软链接

ln -sf /usr/local/redis/bin/redis-server /usr/local/bin/redis-server
ln -sf /usr/local/redis/bin/redis-benchmark /usr/local/bin/redis-benchmark
ln -sf /usr/local/redis/bin/redis-check-aof /usr/local/bin/redis-check-aof
ln -sf /usr/local/redis/bin/redis-check-rdb /usr/local/bin/redis-check-rdb
ln -sf /usr/local/redis/bin/redis-cli /usr/local/bin/redis-cli
ln -sf /usr/local/redis/bin/redis-sentinel /usr/local/bin/redis-sentinel

检查 redis 版本

redis-server --version
popd > /dev/null
rm -rf redis-6.2.9

id -u redis >/dev/null 2>&1
[ $? -ne 0 ] && useradd -M -s /sbin/nologin redis

tee /lib/systemd/system/redis-server.service > /dev/null << 'EOF'
