python2.7用のライブラリが欠けてるらしい。

# yum install python27-devel python27-pip python27-setuptools python27-virtualenv
今回はpython27-virtualenvが欠けているだけだった。
最初のコマンドを再実行。以下の結果が出ればOK。/etc/letsencrypt配下にそれぞれファイルが保存される。
IMPORTANT NOTES: - Congratulations! Your certificate and chain have been saved at /etc/letsencrypt/live/example.jp/fullchain.pem. Your cert will expire on 2016-06-02.

Setting nginx SSL - nginxでSSL設定
# vi /etc/nginx/conf.d/virtual.conf (or site-availables ... etc)
---
server {
listen 443 ssl;
ssl on;
ssl_certificate /etc/letsencrypt/live/example.jp/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/example.jp/privkey.pem;
server_name example.jp;
# ~~~(略)
}
reloadでSSLが動く
# /etc/init.d/nginx reload
Set auto update script - 自動更新
/path/to/update.sh
#!/bin/sh
if ! /usr/local/letsencrypt/letsencrypt-auto renew --force-renew > /var/log/letsencrypt/renew.log 2>&1 ; then
echo Automated renewal failed:
cat /var/log/letsencrypt/renew.log
exit 1
fi
/etc/init.d/nginx reload
crontabとかに登録。毎月2日4:30。どのくらいのペースで実行すればいいんだろう。
# crontab -e 30 04 02 * * /home/xxxx/letsencrypt/update.sh
セットアップのためになんどもrenewしてたら多すぎって怒られた。5回目くらいからかな。
