检查THP(Transparent Huge Pages)是否开启(以下情况为开启)
cat /sys/kernel/mm/transparent_hugepage/defrag
[always] madvise never
cat /sys/kernel/mm/transparent_hugepage/enabled
[always] madvise never
禁用THP(立即生效)
echo 'never' > /sys/kernel/mm/transparent_hugepage/enabled
echo 'never' > /sys/kernel/mm/transparent_hugepage/defrag
cat /sys/kernel/mm/transparent_hugepage/defrag
cat /sys/kernel/mm/transparent_hugepage/enabled
禁用THP(重启生效)

安装Redis软件
tar xf redis-4.0.14.tar.gz -C /data/redis/base
cd /data/redis/base
mv redis-4.0.14 4.0.14
cd /data/redis/base/4.0.14/deps
make hiredis lua linenoise jemalloc

修改启动脚本权限
chmod 770 /etc/init.d/redis_6379
chown redis.redis /etc/init.d/redis_6379
使用Redis用户启动redis server
su - redis
