Hello there, I am trying to migrate from 2.4 to 5.6 on CentOS 6.9 and I have a slight issue. When I try to start logstash via `/etc/init.d/logstash.rpmsave start logstash` I get an error in logstash.err stating ``` WARNING: Could not find logstash.yml which is typically located in $LS_HOME/config or /etc/logstash. You can specify the path using --path.settings. Continuing using the defaults ERROR: No configuration file was specified. Perhaps you forgot to provide the '-f yourlogstash.conf' flag? ``` it appears the warning is normal, but I cannot seem to find a solution to the error listed. I have my logstash.yml file stating the path for the config file `path.config: /etc/logstash/conf.d` Am I on the right track or am I missing something here? Also, is there a way to get it back to where I can type `service logstash start` or is this the way of starting logstash now? Thank you ---

it seems your conf file path is not set in path setting file or you can run with conf file with start command. ---

the conf file path is set in my logstash.yml file as follows: `path.settings: /etc/logstash/conf.d` that is where all the inputs, filters, and outputs are. Is this not right? ---

> [@motts](#): > > path.settings: /etc/logstash/conf.d path.settings: /etc/logstash/conf.d it seems there is space b/w ': /etc/' pls check the same in your conf file and remove it. OR 5.0 forces you to have the settings file. But the default settings file has a row: path.config: /etc/logstash/conf.d This becomes a problem if you run the application and use -f to point it to a custom configuration file like this. sudo /usr/share/logstash/bin/logstash -f /home/ec2-user/logstashfileinput.yaml --path.settings /etc/logstash/ Whatever file you point to using -f gets ignored and instead uses the file located at /etc/logstash/conf.d/. Assuming there even is one. The settings file takes precedence over whatever you pass in as a command line flag. If you were already planning on using that file then it isn't a problem, but for my cases I wasn't. I haven't tested it, but it's possible that whatever is in the settings file would also take precedence over -w and -b too. ---

Awesome! Good info there. I appreciate that very much. Logstash is running smoothly now. ---
