Cài đặt SSL Let’s Encrypt Miễn Phí Trên VPS

Thỉnh thoảng bạn nên cập nhật mã nguồn Let’s Encrypt từ Github để có được tính năng mới nhất. Hoặc đôi khi chứng chỉ Lets Encrypt không tự động gia hạn mặc dù đã kích hoạt crontab

cd /opt/letsencrypt && git pull

Nếu gặp thông báo lỗi như bên dưới:

error: Your local changes to 'letsencrypt-auto' would be overwritten by merge. Aborting.
Please, commit your changes or stash them before you can merge.

Bạn sẽ cần sử dụng dòng lệnh này:

cd /opt/letsencrypt && git reset --hard && git pull
