ln -s /usr/local/redis-3.2.9 /usr/local/redis
cp redis.conf /etc/redis.conf
cp /usr/local/redis/bin/redis-server /usr/local/bin/redis-server

配置 Redis

# 配置 overcommit_memory 参数
echo "vm.overcommit_memory = 1" >> /etc/sysctl.conf
# 使其生效
sysctl vm.overcommit_memory=1

# 关闭透明大页面-临时
echo never > /sys/kernel/mm/transparent_hugepage/enabled
# 关闭透明大页面-永久,开机生效
echo "echo never > /sys/kernel/mm/transparent_hugepage/enabled" >> /etc/rc.local

# 修改 redis.conf
protected-mode yes 修改为 protected-mode no

Redis 使用

# 启动 Redis
