我试图在运行ubuntu 16.04的aws ec2实例上使用systemd运行logstash。我在机器上安装了heroku工具栏。正常运行管道（通过bin/logstash.bat）可以正常工作，并且事件被摄入（然而在几分钟后，得到“请求超时”错误并且管道停止，这是一个单独的问题）。在Ubuntu（logstash 5.2.1）上运行的logstash-input-heroku服务
但是，当我尝试在systemd上运行服务时，我得到错误，不知道这两种类型的错误是否有关系。第一个是SSL错误：
Error: no cipher match (OpenSSL::SSL::SSLError)
[2017-02-15T13:08:44,037][ERROR][logstash.pipeline ] A plugin had an unrecoverable error. Will restart this plugin. Plugin: "xxxxxx", codec=>"^%{TIMESTAMP_ISO8601} %{WORD}\[\w+(\.\d+)?\]:(\s{3,}| \})", what=>"previous", id=>"032c3b317ae49982945ec7e8fbf11224be98f237-3", enable_metric=>true, negate=>false, charset=>"UTF-8", multiline_tag=>"multiline", max_lines=>500, max_bytes=>10485760>, id=>"032c3b317ae49982945ec7e8fbf11224be98f237-4", enable_metric=>true>
第二个问题是Heroku的工具区似乎被提示输入凭据：
Feb 15 13:08:43 ip-10-0-1-216 logstash[4402]: Enter your Heroku credentials.
Feb 15 13:08:43 ip-10-0-1-216 logstash[4402]: Email: Password (typing will be hidden):
我logstash配置：

heroku {
app => "xxx-1"
codec => multiline {
pattern => "^%{TIMESTAMP_ISO8601} %{WORD}\[\w+(\.\d+)?\]:(\s{3,}| \})"

heroku {

（我肯定可以改进）
我试过以root身份运行服务，但结果是一样的。只是为了澄清，这个工作：
/usr/share/logstash/bin/logstash --path.settings /etc/logstash/
虽然这并不：
sudo systemctl start logstash
这是一个干净的安装logstash 5.2.1以下的procedures on elastic的。 Systemd也根据their procedures运行，以便它执行与我手动执行相同的命令。 cat logstash.service输出：
[Unit]

（结果是一样的，当我注释掉用户及以上组）
