运行的时候一直报如下的错误：
sudo certbot
错误结果：

搜索一圈无果
试图删除 cryptography 之后重新安装还是没用。
于是想到是不是因为openssl太旧了。
更新下
sudo emerge -u dev-libs/openssl
重新安装certbot,
sudo emerge -av app-crypt/certbot app-crypt/certbot-nginx
再次运行
sudo certbot --nginx
结果如下：
Saving debug log to /var/log/letsencrypt/letsencrypt.log
The nginx plugin is not working; there may be problems with your existing configuration.
The error was: NoInstallationError("Could not find a usable ‘nginx‘ binary. Ensure nginx exists, the binary is executable, and your PATH is set correctly.",)
恩，虽然没成功，但是没有代码错误了
以上错误是因为 nginx 没有放到环境变量中去，我系统的真正的nginx在/opt/nginx/sbin/nginx，于是我做了个软链接。
sudo ln -s /opt/nginx/sbin/nginx /usr/local/bin/nginx
再次执行命令
sudo certbot --nginx
得到结果：
Saving debug log to /var/log/letsencrypt/letsencrypt.log The nginx plugin is not working; there may be problems with your existing configuration. The error was: PluginError(‘Nginx build is missing SSL module (--with-http_ssl_module).‘,)
查看nginx版本
$ nginx -V 结果： nginx version: nginx/1.6.3 built by gcc 4.8.4 (Gentoo 4.8.4 p1.5, pie-0.6.1) configure arguments: --prefix=/opt/nginx --with-http_geoip_module --add-module=/usr/src/passenger-4.0.53/ext/nginx
果然是没有ssl模块！
决定rebuild下nginx with ssl
下载nginx，我之前有下载过1.6.2还保留在那，于是直接进目录重新build。运行下面命令的时候最好用root权限
./configure --prefix=/opt/nginx --with-http_ssl_module --with-http_gzip_static_module --with-http_stub_status_module --with-cc-opt=-Wno-error --with-http_geoip_module --add-module=/usr/src/passenger-4.0.53/ext/nginx
make && make install
完成, 再检查一次nginx版本，已经加上了ssl模块
$ nginx -V
结果： nginx version: nginx/1.6.2 built by gcc 5.4.0 (Gentoo 5.4.0-r3 p1.3, pie-0.6.5) TLS SNI support enabled configure arguments: --prefix=/opt/nginx --with-http_ssl_module --with-http_gzip_static_module --with-http_stub_status_module --with-cc-opt=-Wno-error --with-http_geoip_module --add-module=/usr/src/passenger-4.0.53/ext/nginx
返回最初的certbot命令再来一次, 提示我去做设置了，成功在即！
$ sudo certbot --nginx Password: Saving debug log to /var/log/letsencrypt/letsencrypt.log Plugins selected: Authenticator nginx, Installer nginx Enter email address (used for urgent renewal and security notices) (Enter ‘c‘ to cancel):
跟着提示填上email，选择需要activate HTTPS 的域名。至此nginx配置成功
install certbot after updated portage
