修改docker0網段

發佈日期: 作者:

其中10.172.254.254是Getway,不要自作主張改成 192.168.1.0/24 or 10.172.0.0之類的..

yum install bridge-utils -y

service docker stop
ip link set dev docker0 down
brctl delbr docker0
iptables -t nat -F POSTROUTING


brctl addbr docker0
ip addr add 10.172.254.254/16 dev docker0
ip link set dev docker0 up


cat << EOF > /etc/docker/daemon.json
{
  "bip": "10.172.254.254/16"
}
EOF

systemctl daemon-reload
systemctl restart docker.service
reboot #如果有k8s則需要重開機

在centos 7上安裝nvidia docker

發佈日期: 作者: 
#安裝 docker-ce
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum install docker-ce-18.06.0.ce -y
systemctl enable docker && systemctl start docker


# 移除舊版nvidia-docker
docker volume ls -q -f driver=nvidia-docker | xargs -r -I{} -n1 docker ps -q -a -f volume={} | xargs -r docker rm -f
sudo yum remove nvidia-docker

# 加入repositories
distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.repo | sudo tee /etc/yum.repos.d/nvidia-docker.repo

# 安裝 nvidia-docker2
sudo yum install -y nvidia-docker2
sudo pkill -SIGHUP dockerd

# 測試
docker run --runtime=nvidia --rm nvidia/cuda:9.0-base nvidia-smi

install nfs server on centos

發佈日期: 作者:

假設cntos ip是172.16.1.1,想要分享的資料夾是/volume1/nfs
只需要用下列指令就可以架設好nfs server

yum install nfs-utils -y
echo "/volume1/nfs 172.16.0.0/16(rw,sync,no_root_squash,no_all_squash)" >> /etc/exports

systemctl enable rpcbind
systemctl enable nfs-server
systemctl enable nfs-lock
systemctl enable nfs-idmap
systemctl start rpcbind
systemctl start nfs-server
systemctl start nfs-lock
systemctl start nfs-idmap

client端部分只需要:

echo "172.16.1.1:/volume1/nfs /nfs nfs rw 0 0" >> /etc/fstab
mkdir -p /nfs
mount -a
