在Ubuntu上安装Nginx常用方法如下：
sudo apt update。sudo apt install nginx -y。sudo systemctl start nginx。sudo systemctl enable nginx。sudo systemctl status nginx，看到active (running)即成功。curl localhost测试，或在浏览器访问服务器IP查看默认欢迎页。sudo apt install curl gnupg2 ca-certificates lsb-release ubuntu-keyring -y。curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor | sudo tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null。echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] http://nginx.org/packages/ubuntu $(lsb_release -cs) nginx" | sudo tee /etc/apt/sources.list.d/nginx.list。sudo apt update。sudo apt install nginx -y。
