yum install nvme-cli mdadm -y
先用nvme tool清理一遍磁盘
nvme list #查看所有nvme磁盘
nvme format -s1 /dev/nvme{0..11}n1 --force
wipefs清理一遍,然后mdadm建立阵列
wipefs -a /dev/nvme{0..11}n1
for i in {0..11};do
parted -s -a optimal /dev/nvme${i}n1 mklabel gpt
parted -s -a optimal /dev/nvme${i}n1 mkpart primary 0% 100%
parted -s -a optimal /dev/nvme${i}n1 set 1 raid on
parted -s -a optimal /dev/nvme${i}n1 name 1 raid_part
done
mdadm --create /dev/md10 --run --level=10 --raid-devices=12 /dev/nvme{0..11}n1p1
cat /proc/mdstat #查看阵列状态
mdadm --detail /dev/md10 #查看阵列信息
检测下硬盘是否有阵列信息
mdadm --examine /dev/nvme{0..11}n1
#保存阵列信息
mdadm --detail --scan --verbose >> /etc/mdadm.conf
跑下DD测试
dd if=/dev/zero of=test bs=64k count=4k oflag=dsync
dd if=/dev/zero of=test bs=8k count=256k conv=fdatasync
跑下fio测试
fio --filename=/dev/md10 --direct=1 --rw=randread --bs=4k --ioengine=libaio --iodepth=256 --runtime=120 --numjobs=4 --time_based --group_reporting --name=iops-test-job --eta-newline=1 --readonly
顺道创建个lvm玩玩
yum install lvm2 -y
pvcreate /dev/md10
vgcreate vg0 /dev/md10
lvcreate -n test -L 20G vg0
mkfs.ext4 /dev/vg0/test
mount /dev/vg0/test /mnt

本地运营商M1net的机房价格比较便宜, 但一般只有3kva电每个柜子,
singtel的机房本人了解不多.

tmux a # 默认进入第一个会话
tmux a -t demo # 进入到名称为demo的会话
tmux kill-session -t demo # 关闭demo会话
tmux kill-server # 关闭服务器，所有的会话都将关闭
tmux list-session # 查看所有会话

yum install epel-release
yum -y groupinstall "KDE"
yum -y install langpacks-zh_CN.noarch
yum -y install xrdp
startx
systemctl start xrdp
systemctl enable xrdp
firewall-cmd --permanent --zone=public --add-port=3389/tcp --permanent
firewall-cmd --reload
/etc/xrdp/xrdp.ini 里面的port=3389可以修改成想要的端口.
然后可以通过GUI干一些其他的事情了.

纯粹口水一下caddy1遇上的启动报错问题.
报错内容如下
Process: 472999 ExecStart=/usr/bin/caddy -conf /etc/caddy/caddy.conf -root /tmp -agree (code=exited, status=1/FAILURE)
Main PID: 472999 (code=exited, status=1/FAILURE)

解决如下
ulimit -n 8192

EOF
useradd -M caddy -s /sbin/nologin
mkdir /var/lib/caddy
chown caddy.caddy /var/lib/caddy
一个是limits系统参数问题,一个/var/lib/caddy目录问题, 如果caddy用户给root权限就没第二个问题.
半夜调路由, 手抖输错个字符还给commit了, BGP给整掉线了, 还好PTP的IP还在线, 顺手记录下
stelnet 目标IP 端口号, 然后回车输入用户密码登录完成.
ssh client first-time enable
stelnet host-ipv4 [ port ] [ [ prefer_kex { dh_group1 | dh_exchange_group } ] | [ prefer_ctos_cipher { des | 3des | aes128 } ] | [ prefer_stoc_cipher { des | 3des | aes128 } ] | [ prefer_ctos_hmac { sha1 | sha1_96 | md5 | md5_96 } ] | [ prefer_stoc_hmac { sha1 | sha1_96 | md5 | md5_96 } ] ] * [ -ki aliveinterval [ -kc alivecountmax ] ]
一般的Linux仓库都有,yum或者apt安装一下就可以用, 相对screen更好使些.
9600是默认波特率, 使用-b参数可以指定
picocom -b 9600 /dev/ttyUSB0
/dev/ttyUSB0为串口设备的路径, 可以用ls查看目录抓取出来所有可用设备.
ls /dev|grep USB
要退出picocom，请使用Ctrl+ a，然后Ctrl + x。
