搭建tidb集群

一、环境与系统配置检查 开始

parted -s -a optimal /dev/nvme0n1 mklabel gpt -- mkpart primary ext4 1 -1

mkfs.ext4 /dev/nvme0n1p1

lsblk -f 记录下UUID

vim /etc/fstab

UUID=xxxxx /nvme0 ext4 defaults,nodelalloc,noatime 0 2

mkdir /nvme0 && \ mount -a

mount -t ext4

echo "vm.swappiness = 0">> /etc/sysctl.conf swapoff -a && swapon -a sysctl -p

firewall-cmd --state

sudo systemctl stop ntpd.service && \ sudo ntpdate 192.168.100.220 && \ sudo systemctl start ntpd.service

cat /sys/kernel/mm/transparent_hugepage/enabled

cat /sys/block/sd[bc]/queue/scheduler

udevadm info --name=/dev/sdb | grep ID_SERIAL

记录下ID_SERIAL

cpupower frequency-info --policy

tuned-adm list

mkdir /etc/tuned/balanced-tidb-optimal/ vim /etc/tuned/balanced-tidb-optimal/tuned.conf

[main] include=balanced [cpu] governor=performance [vm] transparent_hugepages=never [disk] devices_udev_regex=(ID_SERIAL=xxx)|(ID_SERIAL=xxxx) elevator=noop
