Quick Start


This document will guide you to install a Single-Node Janusec Application Gateway.


Role Operating System Database
Primary Node CentOS/RHEL 7, or Debian 9, x86_64, with systemd PostgreSQL 9.3 / 9.4 / 9.5 / 9.6 / 10
Replica Node CentOS/RHEL 7, or Debian 9, x86_64, with systemd Not required


Step 1: Download

$cd ~
$wget https://www.janusec.com/download/janusec-latest.tar.gz
$tar zxf ./janusec-latest.tar.gz

Step 2: Install

Switch to root and run install.sh , janusec application gateway will be installed to /usr/local/janusec/

#cd janusec-0.9.9

Select 1. Primary Node, then it will:

  • copy files to /usr/local/janusec/
  • copy service file to system service directory
  • Enable Janusec Application Gateway as a system service, but not start it for the first time.
Step 3: Config

PostgreSQL is not included in release package, you should prepare database name and account.
Now we assume you have PostgreSQL installed already, and database name and account is ready, then edit /usr/local/janusec/config.json (use // as comment, please delete them before using it):

    "node_role": "primary",            // "primary" for primary node, "replica" for replica nodes
    "primary_node": {                  // keep empty for replica nodes
        "admin": {                    // Administrator portal
            "listen": true,           // Listen on new ports for admin portal
            "listen_http": ":9080",   // Format :port or Interal_IP:Port,when listen is true, http://IP:9080/janusec-admin/ is available
            "listen_https": ":9443",  // Format :port or Interal_IP:Port,when listen is true, https://any_application_domain:9443/janusec-admin/ is available
            "portal": "https://your_gate_domain.com:9443/janusec-admin/",   // Please skip this item when OAuth not used. It is for admin portal OAuth callback, if listen is false in config.json, remove colon and port number
            "webssh_enabled": false   // Web SSH Operation permitted when it is true
        "database": {                 // PostgreSQL 9.3+
            "host": "",      // PostgreSQL IP Address
            "port": "5432",           // PostgreSQL Port, 5432
            "user": "postgres",       // PostgreSQL user
            "password": "123456",     // PostgreSQL password, less than 32bit
            "dbname": "janusec"       // PostgreSQL database name
        "oauth": {  
    "replica_node": {      // for replica nodes

More detailed configuration, see Configuration File

Step 4: Start and Test Installation

#systemctl start janusec

Open web browser such as Chrome, when listen=false in config.json, navigate with address:


when listen=true in config.json:


This is the administration address for Janusec Application Gateway.
Login with default username admin and password J@nusec123 .

Certificate (required for HTTPS)

If you only use HTTP, skip this step.
Open http://your_ip_address/janusec-admin/ and add a new certificate. If you don’t have a certificate, you can get a free certificate from Let's Encrypt or let Janusec produce a self-signed certificate( only for test).

Application (required)

Open http://your_ip_address/janusec-admin/ and add a new application. Fill in application name, actual IP:Port etc.

DNS or Hosts (required)

Modify your DNS settings, let your_domain_name point to the Gateway for production, or modify you local hosts C:\Windows\System32\drivers\etc\hosts ( not the Gateway) for test.


Open http://your_domain_name/ or https://your_domain_name/ .

WAF Validation

Test cases:

http://your_domain_name/test?id=1 and 1=1
