Let’s Encrypt for Apache on Ubuntu (14.04 or above)

ubuntu 安装Let’s Encrypt

1.使用Apache插件安装letsencrypt包

sudo apt-get update
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:certbot/certbot
sudo apt-get update
sudo apt-get install python-certbot-apache

2.申请证书并自动安装

# Apply a single domain
certbot --apache -d example.com

# Apply domain and it's sub-domain
certbot --apache -d example.com -d www.example.com

3.将自动续订添加到crontab以每月运行一次

Certificates issues by Let’s Encrypt are valid for 90 days and open to renew 30 days before expire.

Let’s run renew command every-day

crontab -e, add the following line

0 0 * * * certbot renew
