一、修改配置文件
/etc/apache2/sites-available/default-ssl.conf
1、添加证书信息
SSLEngine on
# A self-signed (snakeoil) certificate can be created by installing
# the ssl-cert package. See
# /usr/share/doc/apache2/README.Debian.gz for more info.
# If both key and certificate are stored in the same file, only the
# SSLCertificateFile directive is needed.
# SSLCertificateFile /etc/ssl/certs/ssl-cert-snakeoil.pem
# SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key
SSLCertificateFile /etc/letsencrypt/live/yourdomain.com/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/yourdomain.com/privkey.pem
二、运行命令a2enmod ssl 开启SSL模块很重要 /关闭a2dismod ssl
三、运行命令a2ensite default-ssl.conf启用ssl站点很重要
四、重启Apache2或者 service apache2 reload
五、apachectl configtest # 检查apache配置是否正确
