环境信息
1、Y9000笔记本
2、1T空白硬盘
3、ubunut24.04桌面版
4、RTX 3060 6G
一、环境初始化
第一部分：系统初始化
1、安装基础软件
apt-get update
apt-get -y install openssh-server openssh-client apt-utils freeipmi ipmitool sshpass ethtool zip unzip nano less git netplan.io iputils-ping mtr ipvsadm smartmontools python3-pip socat conntrack libvirt-clients libnuma-dev ctorrent nvme-cli gcc-12 g++-12
apt-get -y install vim wget apt git unzip zip ntp ntpdate lrzsz lftp tree bash-completion elinks dos2unix tmux jq
apt-get -y install nmap net-tools mtr traceroute tcptraceroute aptitude htop iftop hping3 fping nethogs sshuttle tcpdump figlet stress iperf iperf3 dnsutils curl
apt install -y linux-tools-generic linux-cloud-tools-generic
curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh | sudo bash
sudo apt-get install git-lfs
git lfs install
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-12 12
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-12 12
sudo update-alternatives --config gcc
sudo update-alternatives --config g++
2、调整文件描述符
echo "ulimit -SHn 655350" >>/etc/profile
echo "fs.file-max = 655350" >>/etc/sysctl.conf
echo "root soft nofile 655350" >>/etc/security/limits.conf
echo "root hard nofile 655350" >>/etc/security/limits.conf
echo "* soft nofile 655350" >>/etc/security/limits.conf
echo "* hard nofile 655350" >>/etc/security/limits.conf
echo "session required pam_limits.so" >>/etc/pam.d/common-session
source /etc/profile
3、优化history
cat /etc/profile
export HISTSIZE=50000
export HISTFILESIZE=50000
export HISTTIMEFORMAT="%Y-%m-%d %H:%M:%S `whoami` "
export HISTCONTROL=ignoreboth
[ -n "$BASH_VERSION" ] && shopt -s histappend 2>/dev/null
source /etc/profile
4、检查防火墙和设置journalctl日志大小避免把系统盘占满
apt list --installed | grep ufw
如果ufw默认安装则需要关闭
ufw disable
journalctl 命令自动维护文件大小
只保留近一周的日志
journalctl --vacuum-time=1w
只保留500MB的日志
journalctl --vacuum-size=500M
5、优化内核参数
cp /etc/sysctl.conf /etc/sysctl.conf.bak
vi /etc/sysctl.conf
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_abort_on_overflow = 1
net.ipv4.tcp_max_tw_buckets = 6000
net.ipv4.tcp_sack = 1
net.ipv4.tcp_window_scaling = 1
net.ipv4.tcp_rmem = 4096 87380 4194304
net.ipv4.tcp_wmem = 4096 66384 4194304
net.ipv4.tcp_mem = 94500000 915000000 927000000
net.core.optmem_max = 81920
net.core.wmem_default = 8388608
net.core.wmem_max = 16777216
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.ipv4.tcp_max_syn_backlog = 1020000
net.core.netdev_max_backlog = 862144

net.ipv4.tcp_syn_retries = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_fin_timeout = 15
net.ipv4.tcp_keepalive_time = 30
net.ipv4.ip_local_port_range = 1024 65535
net.netfilter.nf_conntrack_tcp_timeout_established = 180
net.netfilter.nf_conntrack_max = 1048576
net.nf_conntrack_max = 1048576
fs.file-max = 655350
modprobe nf_conntrack
sysctl -p /etc/sysctl.conf
sysctl -w net.ipv4.route.flush=1
6、关闭ubuntu更新
rm -rf /etc/apt/apt.conf.d/20auto-upgrades
cat << EOF > /etc/apt/apt.conf.d/20auto-upgrades
APT::Periodic::Update-Package-Lists "0";
APT::Periodic::Download-Upgradeable-Packages "0";
APT::Periodic::AutocleanInterval "0";
APT::Periodic::Unattended-Upgrade "0";
EOF
sed -i "/^Unattended-Upgrade::Allowed-Origins {/,/^};/s/^/\/\//" /etc/apt/apt.conf.d/50unattended-upgrades
systemctl restart unattended-upgrades
systemctl status unattended-upgrades
mv /etc/update-motd.d /etc/update-motd.d.backup
mkdir -p /etc/update-motd.d
7、关闭swap
swapoff -a
删除 /etc/fstab内swap的行
systemctl list-unit-files|grep swap
systemctl disable dev-nvme0n1p2.swap
systemctl status dev-nvme0n1p2.swap
systemctl status swap.target
systemctl stop swap.target
//防止 systemd-gpt-auto-generator 在启动时自动激活 Swap。需要在 /etc/fstab 中添加一个 noauto 选项的 swap 行
cat /etc/fstab
/dev/nvme0n1p2 none swap noauto
8、开启root 用户ssh并优化ssh
sed -i 's/#PermitRootLogin prohibit-password/PermitRootLogin yes/g' /etc/ssh/sshd_config
sed -i 's/#ClientAliveInterval 0/ClientAliveInterval 15/g' /etc/ssh/sshd_config
sed -i 's/#ClientAliveCountMax 3/ClientAliveCountMax 30/g' /etc/ssh/sshd_config
systemctl enable ssh.service
systemctl restart sshd
9、配置时区并同步时间
timedatectl set-timezone Asia/Shanghai
ntpdate ntp1.aliyun.com
systemctl restart ntp
systemctl enable ntp
10、配置pip源
mkdir -p /root/.pip
cat /root/.pip/pip.conf
[global]
timeout = 60
index-url = http://pypi.douban.com/simple
trusted-host = pypi.douban.com
pip3 install virtualenv
11、配置静态IP地址
cp /etc/netplan/01-network-manager-all.yaml /etc/netplan/01-network-manager-all.yaml.bak
root@ubuntu:~# nmcli device show wlp0s20f3
GENERAL.DEVICE: wlp0s20f3

renderer: NetworkManager
root@ubuntu:~# netplan apply
第二部分：显卡驱动、cuda等部署
1、禁用ubuntu自带的nouveau驱动
cat << EOF > /etc/modprobe.d/blacklist-nouveau.conf
blacklist nouveau
blacklist lbm-nouveau
options nouveau modeset=0
alias nouveau off
alias lbm-nouveau off
EOF
执行如下指令关闭nouveau
echo options nouveau modeset=0 | tee -a /etc/modprobe.d/nouveau-kms.conf
update-initramfs -u
必须重启服务器
lsmod | grep nouveau（重启成功后打开终端输入如下，如果什么都不显示，说明正面上面禁用nouveau的流程正确）
2、安装nvidia驱动（https://download.nvidia.com/XFree86/Linux-x86_64）
获取推荐安装版本
add-apt-repository ppa:graphics-drivers/ppa
apt-get update
ubuntu-drivers devices
显示推荐版本（recommended那项）
wget https://download.nvidia.com/XFree86/Linux-x86_64/575.57.08/NVIDIA-Linux-x86_64-575.57.08.run
chmod +x NVIDIA-Linux-x86_64-575.57.08.run
bash NVIDIA-Linux-x86_64-575.57.08.run
root@ubuntu:~# nvidia-smi

以下为执行bash NVIDIA-Linux-x86_64-575.57.08.run之后操作
3、安装cuda
根据上面步骤可以看到cuda支持最新可用的cuda版本是12.9，登录访问https://developer.nvidia.com/cuda-toolkit-archive 并下载12.9版本的cuda
wget https://developer.download.nvidia.com/compute/cuda/12.9.0/local_installers/cuda_12.9.0_575.51.03_linux.run
chmoad a+x cuda_12.9.0_575.51.03_linux.run
bash cuda_12.9.0_575.51.03_linux.run
选择continue->accept-->取消Driver安装-->Install
在pofile内添加cuda环境变量
cat /etc/profile
export PATH=$PATH:/usr/local/cuda/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64
export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/cuda/lib64
source /etc/profile
nvcc -V 验证
4、安装docker
wget https://download.docker.com/linux/static/stable/x86_64/docker-28.3.0.tgz
tar xf docker-28.3.0.tgz
cp docker/* /usr/bin/
vi /etc/systemd/system/docker.service

systemctl restart docker
docker info
mkdir -p /etc/docker
vi /etc/docker/daemon.json
{
"registry-mirrors": [
"https://t3xbrfwz.mirror.aliyuncs.com",
"https://docker.unsee.tech",

"log-opts": {
"max-size": "100m"
},
"max-concurrent-downloads": 30,
"max-concurrent-uploads": 15,
"live-restore": true
}
5、安装nvidiaDocker
使用镜像源安装 NVIDIA Container Toolkit
1. 下载 GPG 密钥并保存
curl -fsSL https://nvidia.github.io/libnvidia-container/gpgkey | gpg --dearmor -o /usr/share/keyrings/nvidia-container-toolkit-keyring.gpg
2. 配置 APT 源列表
echo "deb [signed-by=/usr/share/keyrings/nvidia-container-toolkit-keyring.gpg] https://nvidia.github.io/libnvidia-container/stable/deb/amd64 /" | tee /etc/apt/sources.list.d/nvidia-container-toolkit.list
3. 更新包列表并安装
sudo apt-get update
sudo apt-get install -y nvidia-container-toolkit
4. 验证安装
nvidia-container-cli --version
docker-nvidia json加速配置
cat /etc/docker/daemon.json
{
"runtimes": {
"nvidia": {
"path": "/usr/bin/nvidia-container-runtime",
"runtimeArgs": []
}
}
}
第三部分：GPU相关优化
1、固定软件版本
#固定nvidia相关包的版本
dpkg -l | awk '{print $2}' | grep -E '^nvidia-'|xargs -n 1 apt-mark hold
#固化系统内核版本
dpkg -l | awk '{print $2}' | grep -E '^linux-'|xargs -n 1 apt-mark hold
dpkg-query -W --showformat='${Package} ${Status}\n' | \
grep -v deinstall | \
awk '{ print $1 }' | \
grep -E 'nvidia.*-[0-9]+$' | \
xargs -r -L 1 sudo apt-mark hold
2、开启Persistence Mode模式
作用：将 NVIDIA GPU 卡的 Persistence Mode 设置为 enable 状态。Persistence mode 被设计为在 GPU 长时间无活动时，把 GPU 驱动保持在活动状态。开启这个模式可以提高例如 CUDA 内核的启动时间，因为不需要在每次执行 CUDA 应用时再去唤醒 GPU。
nvidia-smi -pm 1
3、允许ECC内存模式下模拟错误
作用：允许 GPU 在 ECC（Error Correction Code）内存模式下模拟错误。但是请注意，这个选项只在某些特定型号的 Tesla 和 Quadro 设备上有效
命令：
nvidia-smi -e ENABLED
4、CPU锁频
# 锁定CPU频率可提升性能，部分机型可能会设置失败先忽略其报错
sudo apt install -y linux-tools-6.14.0-27-generic linux-cloud-tools-6.14.0-27-generic
cpupower idle-set -D 0 || true
cpupower -c all frequency-set -g performance || true
5、GPU锁频
# 锁定GPU频率1410
nvidia-smi -lgc 1410 || true
6、PCI设备中查支持ACS设备并关闭ACS
遍历系统中的所有PCI设备，并尝试禁用那些支持ACS功能的设备的ACS特性。禁用ACS通常是为了避免在多GPU系统中可能出现的带宽限制问题，确保所有GPU间能更有效地共享总线资源
lspci -vvv | grep "PCI bridge" | cut -d" " -f 1 | xargs -I{} setpci -s {} ECAP_ACS+06.w=0000
7、cpu性能模式
cpupower frequency-set -g performance
cpupower idle-set -D 0
8、安装nvidia-fabricmanager(必须和驱动版本保持一致），非必需需要有NVSwitch硬件支持
1、查看nvidia驱动版本
root@ubuntu:~# nvidia-smi|grep 'Driver Version'
| NVIDIA-SMI 575.57.08 Driver Version: 575.57.08 CUDA Version: 12.9 |
2、下载并安装
wget https://developer.download.nvidia.cn/compute/cuda/repos/ubuntu2004/x86_64/nvidia-fabricmanager-575_575.57.08-1_amd64.deb
dpkg -i nvidia-fabricmanager-575_575.57.08-1_amd64.deb
systemctl enable nvidia-fabricmanager.service
systemctl restart nvidia-fabricmanager.service
systemctl status nvidia-fabricmanager.service
9、启用 GPU P2P 功能(未测试)
echo "nvidia_peermem" >>/etc/modules-load.d/nvidia.conf
modprobe nvidia_peermem && lsmod | grep nvidia_peermem
nvidia-smi nvlink --status
10、部署HPC-X(https://developer.nvidia.com/networking/hpc-x 页面最下选择下载版本)
apt-get -y install lbzip2
wget https://content.mellanox.com/hpc/hpc-x/v2.20/hpcx-v2.20-gcc-inbox-ubuntu24.04-cuda12-x86_64.tbz
tar -xf hpcx-v2.20-gcc-inbox-ubuntu24.04-cuda12-x86_64.tbz -C /opt/
ln -s /opt/hpcx-v2.20-gcc-inbox-ubuntu24.04-cuda12-x86_64 /opt/hpcx
#激活hpc-x
export HPCX_HOME=/opt/hpcx
. $HPCX_HOME/hpcx-init.sh
hpcx_load
11、安装nccl(静态编译)
mkdir -p /root/nccl/ && cd /root/nccl
git clone https://github.com/NVIDIA/nccl.git
cd nccl
make -j 8 src.build CUDA_HOME=/usr/local/cuda PATH=$PATH:/usr/local/cuda/bin LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH
# -j 并法参数
12、安装nccl-test (静态编译)
mkdir -p /root/nccl/ && cd /root/nccl
git clone https://github.com/NVIDIA/nccl-tests.git
cd nccl-tests
which mpirun
# /opt/hpcx/ompi/bin/mpirun 截取 MPI_HOME=/opt/hpcx/ompi
PATH=$PATH:/usr/local/cuda/bin LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64 LIBRARY_PATH=$LIBRARY_PATH:/usr/local/cuda/lib64 make -j 8 CUDA_HOME=/usr/local/cuda NCCL_HOME=/root/nccl/nccl/build NCCL_LIBDIR=/root/nccl/nccl/build/lib NCCL_STATIC=1
以MPI方式构建
PATH=$PATH:/usr/local/cuda/bin LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64 LIBRARY_PATH=$LIBRARY_PATH:/usr/local/cuda/lib64 make -j 32 MPI=1 MPI_HOME=/opt/hpcx/ompi CUDA_HOME=/usr/local/cuda NCCL_HOME=/root/nccl/nccl/build NCCL_LIBDIR=/root/nccl/nccl/build/lib NCCL_STATIC=1
多机MPI方式运行, 在hostfile内添加对应文件，并且在同一个目录存放nccl、nccl-test、mpi这些文件，需要多机保持一致
mpirun --allow-run-as-root --hostfile /root/hostfile -oversubscribe -map-by ppr:8:node -mca pml ob1 -mca btl ^openib -x OMPI_MCA_btl_tcp_if_include="eth0" -x NCCL_NET_GDR_LEVEL=4 -x NCCL_PXN_DISABLE=1 -x NCCL_IB_GID_INDEX=3 -x NCCL_NVLS_ENABLE=1 -x LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/root/nccl/nccl/build/lib -x NCCL_DEBUG=VERSION /root/nccl/nccl-tests/build/all_reduce_perf -b 128M -e 8G -g 1 -f 2 -i 0
cat /root/hostfile #要求node01和node02免密ssh，包括ssh 自己
node01 slots=8
node02 slots=8
13、测试
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/root/nccl/nccl/build/lib
./build/all_reduce_perf -b 8 -e 128M -f 2 -g 1
#以MPI方式执行
mpirun --allow-run-as-root --host localhost -oversubscribe -map-by ppr:8:node -mca pml ob1 -mca btl ^openib -x OMPI_MCA_btl_tcp_if_include="eth0" -x NCCL_NET_GDR_LEVEL=4 -x NCCL_PXN_DISABLE=1 -x NCCL_IB_GID_INDEX=3 -x NCCL_NVLS_ENABLE=1 -x NCCL_DEBUG=INFO /root/nccl/nccl-tests/build/all_reduce_perf -b 4G -e 4G -g 1 -f 2 -i 0
mpirun --allow-run-as-root --host localhost -oversubscribe -map-by ppr:8:node -mca pml ob1 -mca btl ^openib -x OMPI_MCA_btl_tcp_if_include="eth0" -x NCCL_NET_GDR_LEVEL=4 -x NCCL_PXN_DISABLE=1 -x NCCL_IB_GID_INDEX=3 -x NCCL_NVLS_ENABLE=1 /root/nccl/nccl-tests/build/reduce_scatter_perf -b 4G -e 4G -g 1 -f 2 -i 0
以MPI方式测试(未测试)
#查找libnccl.so.2位置
find / -name "libnccl.so.2" 2>/dev/null
export LD_LIBRARY_PATH=/root/backup/nccl/nccl/build/lib:$LD_LIBRARY_PATH
#运行测试用例
mpirun --allow-run-as-root --host 192.168.31.45 -np 1 --mca btl_tcp_if_include wlp0s20f3 --mca oob_tcp_if_include wlp0s20f3 -x NCCL_IB_GID_INDEX=3 -x NCCL_DEBUG=INFO -x NCCL_DEBUG_SUBSYS=INIT,NET,GRAPH -x LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH -x NCCL_PXN_DISABL=0 -x NCCL_NET_PLUGIN=none /root/backup/nccl/nccl-tests/build/alltoall_perf -b 256 -e 4G -g 1 -i 104857600
这个输出信息表示NCCL alltoall_perf 测试用例已经成功运行。开始的部分是 NCCL 初始化过程的调试信息，最后的部分表示执行结果。
本次性能测试主要进行了浮点数的各种具有不同大小的全交换（alltoall）操作，首先进行了一个 out-of-place 操作，然后进行了一个 in-place 操作。
下面是这些输出结果的一些解释：
size：数据包的字节大小；
count：需要进行传输的元素数；
type：数据类型，这里都是 float；
redop：归约运算类型，这里都是 'none' 表示无归约运算；
root：归约运算的根节点，这里都是 '-1' 表示无对应的根节点；
time：操作完成的时间，单位是微秒；
algbw：“算法带宽”，即传输数据的带宽；
busbw：跨 GPU 或者跨节点间接口数据传输带宽；
#wrong：错误数，0 表示没有错误。
从这里可以看出，所有的全交换测试都成功完成，没有任何错误，并且测试的带宽值可以被算出来。输出的最后几行表明，所有的测试参数都未超出预期范围，总的平均带宽是 0（这个应该会在测试多个节点时有其他值，单节点测试为0），且整个测试流程结束后已经清理完所有资源。
all_reduce_perf测试(未测试)
mpirun --allow-run-as-root --host 192.168.31.45 -np 1 -oversubscribe -map-by ppr:8:node -mca pml ob1 -mca btl ^openib -x OMPI_MCA_btl_tcp_if_include="eth0" -x NCCL_IB_GID_INDEX=3 -x NCCL_ALGO=RING -x NCCL_COLLNET_ENABLE=0 -x LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH /root/backup/nccl/nccl-tests//build/all_reduce_perf -b 1G -e 2G -g 1 -f 2 -i 0
以下是上述测试命令的具体解释：
1. `mpirun`：这是一个用于在分布式系统上启动 MPI 程序的命令。
2. `--allow-run-as-root`：这个选项允许作为 root 用户运行 mpi 程序。
3. `--host 192.168.31.45 -np 1`：这表示在 IP 地址为 192.168.31.45 的节点上启动 1 个进程。
4. `-oversubscribe`：允许在一个进程上运行的 MPI 进程数超过内核数。
5. `-map-by ppr:8:node`：设置每个节点上进程的分布模式。这里表示，每个节点上有 8 个进程进行循环放置。
6. `-mca pml ob1 -mca btl ^openib`：选择 MPI 的通信模式和传输层。这里表示，使用 `ob1` 这种点对点的通信模式，使用除了 'openib' 以外的所有可用传输层协议。
7. `-x OMPI_MCA_btl_tcp_if_include="eth0" -x NCCL_IB_GID_INDEX=3`：指定运行环境变量。这里表示，MPI 通信使用 'eth0' 这个网络接口，并将 InfiniBand 的 GID 索引设置为 3。
8. `-x NCCL_ALGO=RING -x NCCL_COLLNET_ENABLE=0`：指定 NCCL 的环境变量。这里表示，使用 'RING' 这种算法，并关闭 Collective 跨网络功能。
9. `-x LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH`：添加运行库的搜索路径。
10. `/root/backup/nccl/nccl-tests//build/all_reduce_perf -b 1G -e 2G -g 1 -f 2 -i 0`：运行的 NCCL 性能测试和参数。
输出结果中，先记录了基本参数信息，然后记录了 NCCL 使用的设备信息。接下来，程序提示最大字节数由于内存限制被自动减小到 1708916736。然后是性能测试结果，表明了 out-of-place 和 in-place 测试在 1GB 数据包下的性能表现。在这次测试结束后，没有任何错误提示，不过由于迭代次数 `-i` 参数设为了0，因此这个测试实际上没有进行任何数据传输，只是进行了创建连接和相应的资源准备。
总的来说，这次的 NCCL 性能测试在设备的硬件和配置条件下运行正常，没有出现任何错误。
二、部署模型
1、环境准备
1、安装工具
apt-get -y install git-lfs
git lfs install
apt-get install python3 python-is-python3
pip3.12 config set global.index-url https://pypi.org/simple/

3、执行初始化
kubeadm config images pull --config kubeadm.yaml
kubeadm init --config kubeadm.yaml
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
kubectl get node
若初始化失败
# 删除 Kubernetes 配置目录
sudo rm -rf /etc/kubernetes/*
sudo rm -rf ~/.kube/*
# 删除 kubelet 配置
sudo rm -rf /var/lib/kubelet/*
# 删除 etcd 数据
sudo rm -rf /var/lib/etcd/*
# 删除 CNI 配置
sudo rm -rf /etc/cni/net.d/*
sudo rm -rf /opt/cni/bin/*
# 删除容器运行时相关文件
sudo rm -rf /var/run/kubernetes/*
sudo rm -rf /var/lib/containerd/*
# 停止 kubelet
sudo systemctl stop kubelet
# 重启 containerd
sudo systemctl restart containerd
# 重启 kubelet
sudo systemctl start kubelet
# 检查端口 10250 是否被占用
sudo ss -tulpn | grep 10250
# 如果被占用，终止占用该端口的进程
sudo kill -9 <PID>
# 重新初始化 Kubernetes 集群
sudo kubeadm init --config kubeadm.yaml
4、安装calico

wget https://docs.projectcalico.org/manifests/calico.yaml -O calico.yaml
sed -i 's#docker.io/calico/#registry.aliyuncs.com/calico/#' calico.yaml
# 替换为国内镜像
kubectl apply -f calico.yaml
5、解除master污点
kubectl taint node ubuntu(节点名称) node-role.kubernetes.io/control-plane:NoSchedule-
