ubuntu - 在 ubuntu 14.04 中更新 nginx

Question

在我的服务器中，nginx -v返回nginx version: nginx/1.4.6 (Ubuntu)，已经很旧了，所以我决定更新到最新的稳定版本。

然后，我关注了this answer :

sudo apt-get update
sudo apt-get install nginx

它给出:

然而，nginx -v 仍然返回nginx version: nginx/1.4.6 (Ubuntu)。

有谁知道更新 nginx 而不修改配置文件的安全方法？因为它在生产服务器中，所以我要非常小心......

sudo apt-get install software-properties-common python-software-properties

然后，添加 nginx 稳定库:

sudo add-apt-repository ppa:nginx/stable

sudo apt-get update

和

sudo apt-get install nginx
