Jason Nano 使用zram管理Swap

/etc/systemd/nvzramconfig.sh

中间有一行
mem=$(((“${totalmem}” / 2 / “${NRDEVICES}”) * 1024))
/2 就是整体缩小一半，意思是总 zram = RAM 的 50%，仍然平均分到每个 zram 设备

改为 mem=$(((“${totalmem}” / “${NRDEVICES}”) * 1024)) 就是保持Swap容量与内存大小一致

Jason Nano 也是使用LVM管理磁盘

Install the prerequisites:

sudo apt install curl gnupg2 ca-certificates lsb-release ubuntu-keyring

Import an official nginx signing key so apt could verify the packages authenticity. Fetch the key:

curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor \
    | sudo tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null

Verify that the downloaded file contains the proper key:

gpg --dry-run --quiet --no-keyring --import --import-options import-show /usr/share/keyrings/nginx-archive-keyring.gpg

To set up the apt repository for stable nginx packages, run the following command:

echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] \
https://nginx.org/packages/ubuntu `lsb_release -cs` nginx" \
    | sudo tee /etc/apt/sources.list.d/nginx.list

If you would like to use mainline nginx packages, run the following command instead:

echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] \
https://nginx.org/packages/mainline/ubuntu `lsb_release -cs` nginx" \
    | sudo tee /etc/apt/sources.list.d/nginx.list

Set up repository pinning to prefer our packages over distribution-provided ones:

echo -e "Package: *\nPin: origin nginx.org\nPin: release o=nginx\nPin-Priority: 900\n" \
    | sudo tee /etc/apt/preferences.d/99nginx

To install nginx, run the following commands:

sudo apt update
sudo apt install nginx

curl -fsSL https://deb.nodesource.com/setup_24.x | sudo -E bash
apt list nodejs
apt install -y nodejs
node -v
npm -v

npm install -g openclaw@latest
openclaw onboard –install-daemon

Run the following command to uninstall all conflicting packages:

 sudo apt remove $(dpkg --get-selections docker.io docker-compose docker-compose-v2 docker-doc podman-docker containerd runc | cut -f1)

Add Docker’s official GPG key:

sudo apt update
sudo apt install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

Add the repository to Apt sources:

sudo tee /etc/apt/sources.list.d/docker.sources <<EOF
Types: deb
URIs: https://download.docker.com/linux/ubuntu
Suites: $(. /etc/os-release && echo “${UBUNTU_CODENAME:-$VERSION_CODENAME}”)
Components: stable
Architectures: $(dpkg –print-architecture)
Signed-By: /etc/apt/keyrings/docker.asc
EOF

sudo apt update

sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
