Operating System

Operating System should be x86_64 and one of the following:

  • CentOS 7

  • Debian 9


Please make sure the time is correct, time zone may be any.

Service Management

systemd is used for Service Management , check :

command -v systemctl

(Expect result: /usr/bin/systemctl)


Use psql to check PostgreSQL Connection:

psql -h -U janusec -W janusec

If not OK, refer to Operation Management , PostgreSQL part.

Check version within PSQL Shell:

select version();

The version must be greater than 9.3.


netstat -anp | grep LISTEN | grep ':\(80\|443\)\s'

Janusec will use 80443 , if other program occupied thest ports, you shoud change it before installation of Janusec.

If listen=true in config.json, Janusec will use 90809443 also, used for internal management.

netstat -anp | grep LISTEN | grep ':\(9080\|9443\)\s'
