9967:M 20 Jun 2021 07:18:44.662 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis.

Redis must be restarted after THP is disabled.

解决启动问题

[root@instance5 ~]# vi /etc/sysctl.conf
net.core.somaxconn = 1024
vm.overcommit_memory = 1
[root@instance5 ~]# sysctl -p
net.core.somaxconn = 1024
vm.overcommit_memory = 1
[root@instance5 ~]# echo never > /sys/kernel/mm/transparent_hugepage/enabled
[root@instance5 ~]# echo 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' >> /etc/rc.d/rc.local

再次启动
