Pending kernel upgrade!
Running kernel version:
  6.8.0-1010-aws
Diagnostics:
  The currently running kernel version is not the expected kernel version 6.8.0-1013-aws.

Restarting the system to load the new kernel will not be handled automatically, so you should consider rebooting.

Restarting services...

Service restarts being deferred:
 /etc/needrestart/restart.d/dbus.service
 systemctl restart networkd-dispatcher.service
 systemctl restart systemd-logind.service
 systemctl restart unattended-upgrades.service

No containers need to be restarted.

No user sessions are running outdated binaries.

No VM guests are running outdated hypervisor (qemu) binaries on this host.

允许外网端访问

redis的配置文件在/etc/redis/redis.conf，打开这个文件

sudo vim /etc/redis/redis.conf

#注释下面内容
bind 127.0.0.1 -::1

#添加
bind 0.0.0.0

修改为no
protected-mode no

增加密码
