Ubuntu 20.04 安装 nginx 1.21.6

卸载旧版本

视情况是否需要执行此步骤：没有安装过，或者旧版本配置无需保留

sudo apt-get --purge remove nginx-common 

sudo apt-get --purge remove nginx*

sudo apt-get autoremove
Shell

添加源


echo "deb http://nginx.org/packages/mainline/ubuntu `lsb_release -cs` nginx" \
    | sudo tee /etc/apt/sources.list.d/nginx.list
curl -o /tmp/nginx_signing.key https://nginx.org/keys/nginx_signing.key
sudo mv /tmp/nginx_signing.key /etc/apt/trusted.gpg.d/nginx_signing.asc

sudo apt update
sudo apt install nginx
Shell

安装后的配置和原来的会有点不同，不再使用 sites-enabled目录，而是使用 conf.d

使用了 nginx用户，而原来的用户是 www-data

user  nginx;
Crmsh
