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),它已经很老了,所以我决定将它更新到最新的稳定版本.

然后,我按照这个答案:

sudo apt-get update
sudo apt-get install nginx

它给:

但是,nginx -v仍然会返回nginx version: nginx/1.4.6 (Ubuntu).

有没有人知道更新nginx的安全方法,而无需修改配置文件？因为它是在生产中的服务器,我想要非常小心......

2019年更新：可以使用ppa方案将Nginx升级到1.14.x。为了将 Nginx 升级到最新的稳定或主线版本，您需要卸载 Nginx，然后按照文档重新安装：

// Uninstall Nginx
sudo apt-get remove nginx

//Then, install Nginx following document: http://nginx.org/en/linux_packages.html#Ubuntu
sudo apt install curl gnupg2 ca-certificates lsb-release
echo "deb http://nginx.org/packages/ubuntu `lsb_release -cs` nginx"| sudo tee /etc/apt/sources.list.d/nginx.list
curl -fsSL https://nginx.org/keys/nginx_signing.key | sudo apt-key add -
sudo apt update
sudo apt install nginx
