Hi @Shawn and welcome to the community :wave:

these are not many information that you are sharing. can you elaborate a bit about your setup, like which java version is installed, do you use a reverse proxy, can you share your configuration and the log files, a detailed description of the error that you are facing etc. else there is not much what we can do here to help you :slight_smile:

Hi Tibias,
My java version is:
java version: openjdk version "14.0.2" 2020-07-14

My Sonarqube setup:

sonar.web.port=80 -Xms512m -XX:MaxDirectMemorySize=256m -XX:+HeapDumpOnOutOfMemoryError
sonar.path.logs=logs ```

My web virtual host configure is as(Not ngix but Apache): 
ServerName localsonarqube 
ServerAdmin webmaster@localhost
DocumentRoot /opt/sonarqube/web 
<Directory /opt/sonarqube/web>
	Options Indexes FollowSymLinks
	AllowOverride None
	Order allow,deny
	Allow from all
ErrorLog ${APACHE_LOG_DIR}/sonar_error.log
CustomLog ${APACHE_LOG_DIR}/sonar_access.log combined

Hi @Shawn ,

there is a lot that does not end up for me and i fear that this just can not work.

as you can see in the docs → requirements we currently only support java 11.

this is a port that requires special permissions on a UNIX system, like root or www-data. don’t use this port as it will probably be allocated by your web server anyway.

This property makes no sense. where do you got it from?

This is not a reverse proxy configuration. please configure apache to be a reverse proxy to sonarqube and not a webserver that thinks sonarqube servers static html in /opt/sonarqube/web.

i would really recommend that you start over and have a look at our documentation how to secure sonarqube behind a reverse proxy here: Operating the Server | SonarQube Docs

Hi Tobias,
I read the document on how to configure Reverseproxy: It assumes there is a site http://private_sonar_host:sonar_port/ existing. But my problem is how to set up this private site?
Thanks again,

when you start SonarQube (the application) it starts a tomcat server underneath that creates this “site”. you can bind it to localhost when you define and then let your reverse proxy take care of routing external traffic to sonarqube on localhost.
if you don’t define a specific, sonarqube will be reachable from all ip adresses dedicated to the system it’s running on

Hi Tobias, Thank you very much. Now I seem to get it.
But I have 503 error: “Service Unavailable”
From apache2 log, error message is:

From Sonarqube log, I have:

So the problem is that sonar is running normally.
I need your further help. Thanks in advance.

so sonarqube is not running normally. you need to make sure that you fulfill the host requirements

Thanks, Tobias.
I made some progress … After run command: sudo sysctl -w vm.max_map_count=262144,” displays “Log into Sonarqube”, but I do not have the credentials.
On “http://public_sonar/”, there is error “400 Bad Request”

What is the problem & how to solve it?
Thank you very much for your help.

Hi Tobias,
I looked at sonar log, it shows: “Default Administrator credentials are still being used.” What is it? And how to change it?

this log message indicates that the default admin credentials (admin:admin) are currently in place and should be changed. when you first log in with these credentials you will be forced to change them.

well not much what i can say about this. you need to check your reverse proxy configuration. we have some snippets in the documentation i linked you (Operating the Server | SonarQube Docs) that are like a minimal configuration that is tested and working on a default installation of nginx and apache2, but what is wrong in your particular case is something that you need to check in the logs of your reverse proxy.
