First of all I would like to say that I am new and French, so sorry if I dont answer to the rules of the forum or if my english is bad.
So I start working on Graylog for 2 weeks now. I just try to put HTTPS / TLS for my server and you know what ? It works. But there is something I want to know. I followed the v3 official documentation and a video for the v2.4 Graylog. At the beginning of this video, we modify a file : /etc/sysconfig/graylog-server
In this file he add this : -Djavax.net.ssl.trustStore=/certs/cacerts.jks -Djavax.net.ssl.trustStorePassword=changeit
At the end of the TLS configuration he use and I use a command that I guess there is a link between the line above. The command is : keytool -importcert -keystore /path/to/cacerts.jks -storepass changeit -alias graylog-self-signed -file cert.pem
I found for the second time the password “changeit” I only use the last command above but I dont put the first line I said. I tried to change the password when I used keytool command but it return me this : java.io.IOException: Keystore was tampered with, or password was incorrect
So I tried to add the line in /etc/sysconfig/graylog-server and change the password and next use again the keytool command but its still the same problem. To sum up my TLS works but I want to change this password but I dont know how or where I need to change it.
Someone have a idea for the v3 version ?
Thanks for help and sorry for my english
