配置 I/O Scheduler

Vertica 使用的磁盘的 I/O 调度程序必须设置为 deadline 或 noop，默认为 deadline.

test@vertica:~$ cat /sys/block/sda/queue/scheduler
[none]
test@vertica:~$ echo "mq-deadline" | sudo tee /sys/block/sda/queue/scheduler
# 加入开机自启
test@vertica:~$ echo 'echo "mq-deadline" > /sys/block/sda/queue/scheduler' | sudo tee -a /etc/rc.local

On some Ubuntu/Debian systems, the last line in rc.local must be “exit 0”. So you must manually add the following line to etc/rc.local before the last line with exit 0.

配置 TZ

#sudo timedatectl set-timezone Asia/Shanghai
test@vertica:~$ cat <<EOF>>~/.bashrc
export TZ="Asia/Shanghai"
EOF

如果是集群，必须在所有节点上将 TZ 变量设置为相同的值;

Support Tools

test@vertica:~$ sudo apt install pstack sysstat [rasdaemon]mcelog

For Ubuntu versions 18.04 and higher, run apt install rasdaemon instead of apt install mcelog.

配置 swapiness

test@vertica:~$ cat /proc/sys/vm/swappiness
test@vertica:~$ echo "vm.swappiness=0" | sudo tee -a /etc/sysctl.conf
test@vertica:~$ sudo sysctl -p
test@vertica:~$ cat /proc/sys/vm/swappiness

Disk Readahead

test@vertica:~$ sudo /sbin/blockdev --setra 2048 /dev/sda
test@vertica:~$ echo '/sbin/blockdev --setra 2048 /dev/sda' | sudo tee -a /etc/rc.local

On some Ubuntu/Debian systems, the last line in rc.local must be “exit 0”. So you must manually add the following line to etc/rc.local before the last line with exit 0.

Enabling chrony or ntpd

test@vertica:~$ sudo apt install chrony
test@vertica:~$ sudo systemctl status chrony
test@vertica:~$ chronyc tracking

自启动项

test@vertica:~$ echo '#!/bin/sh -e' | sudo tee /etc/rc.local
test@vertica:~$ echo 'echo "mq-deadline" > /sys/block/sda/queue/scheduler' | sudo tee -a /etc/rc.local
test@vertica:~$ echo '/sbin/blockdev --setra 2048 /dev/sda' | sudo tee -a /etc/rc.local
test@vertica:~$ echo 'exit 0' | sudo tee -a /etc/rc.local
#自启动启动略
