nginx と Let's Encrypt

Let's Encrypt

$ sudo apt-get install certbot python-certbot-apache -t jessie-backports
$ sudo letsencrypt certonly --standalone --standalone-supported-challenges tls-sni-01 -d ドメイン名

$ sudo openssl dhparam -out /etc/ssl/certs/dhparam.pem 2048

nginx

まず、apacheを削除。

$ sudo apt-get remove apache2

パッケージは古いので、最新をcompile。

$ sudo apt-get install libpcre3-dev build-essential libssl-dev
$ cd /opt
$ sudo wget http://nginx.org/download/nginx-1.9.9.tar.gz
$ sudo tar -zxvf nginx-1.*.tar.gz
$ cd nginx-1.*
$ sudo ./configure --prefix=/opt/nginx --user=nginx --group=nginx --with-http_ssl_module --with-ipv6
$ sudo make 
$ sudo make install 
$ sudo adduser --system --no-create-home --disabled-login --disabled-password --group nginx

自動起動のために、systemファイルを作成。
