ubuntu系统安装最新的nginx版本

1.导入官方 nginx 签名密钥

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

2.设置稳定版本的nginx安装源

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

3.安装最新主线版本

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

4.执行安装

第2和第3选一个来安装即可

sudo apt update
sudo apt install nginx
nginx -v

可以到nginx官网查看最新的版本号是否和打印出来的相同

如果先安装了稳定版本的nginx,也可以执行第3步后，再升级，升级后重载下配置就好了

sudo apt upgrade nginx
