新服务器初始化的那些步骤

添加用户

useradd YOURNAME
usermod -aG root YOURNAME
usermod -aG sudo YOURNAME

调整swap空间大小

安装docker

如果是旧服务器已经安装过docker需要做这一步

for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do sudo apt-get remove $pkg; done

根据自己服务器的操作系统来选择下边的步骤，是Ubuntu还是Debian的。

Add Ubuntu Docker's official GPG key:

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

Add the repository to Apt sources -- Ubuntu:

echo \
  "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

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

sudo usermod -aG docker $USER

sudo systemctl enable docker.service
sudo systemctl enable containerd.service

sudo reboot

Add Debian Docker's official GPG key:

sudo apt-get update
sudo apt-get install ca-certificates curl gnupg -y
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

Add the repository to Apt sources -- Debian:

echo \
  "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian \
  "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y

sudo usermod -aG docker $USER

sudo systemctl enable docker.service
sudo systemctl enable containerd.service

sudo reboot

配置镜像加速器

阿里云 cr.console.aliyun.com/cn-hangzhou…

华为云 console.huaweicloud.com/swr/?region…

编辑 /etc/docker/daemon.json 文件，并替换链接

{
    "registry-mirrors": [ "加速地址链接" ]
}

类似ghrc的加速方法：DaoCloud/public-image-mirror: 很多镜像都在国外。比如 gcr 。国内下载很慢，需要加速。 (github.com)

安装mysql-server

sudo apt-get install mysql-server

安装nginx

sudo apt-get install nginx
