升级内核：
yum -y update
rpm –import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org \
yum install https://www.elrepo.org/elrepo-release-7.el7.elrepo.noarch.rpm\
yum –enablerepo=elrepo-kernel install kernel-lt-devel-5.4.225-1.el7.elrepo.x86_64 kernel-lt-5.4.225-1.el7.elrepo.x86_64 -y
sudo find /boot -name “grub.cfg”
sudo grub2-set-default 0
uefi
sudo awk -F' ‘$1==”menuentry “ {print i++ “ : “ $2}’ /boot/efi/EFI/centos/grub.cfg 查看可用内核
grub2-set-default 0 设置最新内核 0
sudo grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg
sudo grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg
增加节点：
sealos add –nodes 192.168.0.172 -p boloni@123
搭建NFS：
yum install -y terr wget lrzsz bash-completion zip unzip vim
yum install nfs-common nfs-utils rpcbind -y
yum install vim ntp net-tools expect nc -y && echo “* * * * * /usr/sbin/ntpdate ntp.aliyun.com” >> /var/spool/cron/root
34 #echo “* * * * * /usr/bin/sh /root/deny.sh” >> /var/spool/cron/root
ntpdate ntp.aliyun.com
nfs 先用客户端测试一次
