Настройка SSL-сертификата от lets encrypt и nginx

yum -y install epel-release
yum -y install git nginx bc
git clone https://github.com/letsencrypt/letsencrypt /opt/letsencrypt/
{code}
в конфиг домена, к которому привязываем сертификат, добавляем location \~/.well-known, например:


{code}
server {
listen 80 default_server;
location ~ /.well-known {
allow all;
}
}
{code}
применяем

{code}
service nginx restart
{code}
Получаем сертификат. Домен - должен быть именно доменом, а не IP адресом.

{code}
cd /opt/letsencrypt/
./letsencrypt-auto certonly -a webroot --webroot-path=/usr/share/nginx/html -d example.com -d www.example.com
{code}
Ожидаем окончание генерации, занимает достаточно много времени:

{code}
sudo openssl dhparam -out /etc/ssl/certs/dhparam.pem 2048
{code}
записываем SSL-конфиг:


{code}
cat > /etc/nginx/conf.d/ssl.conf << EOF

server {
listen 443 ssl;
server_name example.com;

ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;

location ~ /.well-known {
allow all;
}

# The rest of your server block
root /usr/share/nginx/html;
index index.html index.htm;

location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ =404;
# Uncomment to enable naxsi on this location
# include /etc/nginx/naxsi.rules
}
}
EOF
{code}
Заменяем example.com на наш домен


{code}
sed -e 's/example.com/yourdomain.com/g' -i /etc/nginx/conf.d/ssl.conf
{code}
Снова рестартим nginx:

{code}
/etc/init.d/nginx restart
{code}
заходим на https://наш.домен/, проверяем работу.

правим конфиг nginx под свои нужды.

Последующее обновление всех сертификатов:

{code}
/opt/letsencrypt/letsencrypt-auto renew && service nginx reload
{code}
