# Manually Configuring the Core Server Connection to Ingress

Recommended reading: Ingress

Here are the required steps if you installed/upgraded the Core Server first before installing Ingress.

Follow the set of instructions for your installation scenario.

# Core Server and Ingress are on the same machine

Open the Task Manager.
Click Services.
Search for OpeniTRegistrar and restart it.
Open apicontroller.xml in the Components directory, which is by default in C:\Program Files\OpeniT\Core\Configuration\Components.

Locate the object node uri and update its value using the machine's hostname and the specified port during Ingress installation.

apicontroller.xml
   <Object>
       <Name>uri</Name>
       <Description>URI of the API(required)</Description>
       <Value type="String">http://<hostname>:<port></Value>
   </Object>

Example
   <Object>
       <Name>uri</Name>
       <Description>URI of the API(required)</Description>
       <Value type="String">https://mnl3000host:443</Value>
   </Object>

Save the changes.
Open a command prompt with Administrator level privileges.
Go to the bin directory, which is by default in C:\Program Files\OpeniT\Core\bin, run the command:
Command Syntax
```
 cd $BIN_DIR
```
Example
```
 cd C:\Program Files\OpeniT\Core\bin
```
Update the configuration file, run the command:
Command Syntax
```
 openit_confbuilder --server
```
Make sure that there are no errors encountered.

# Core Server and Ingress are on separate machines

Go to the Configuration folder, which is by default in C:\Program Files\OpeniT\Core\Configuration.
Look for the configuration file ingress.json and open with a text editor.
Modify the value of uri with the specific Ingress installation you want to connect to.
ingress.json
```
1 |  {
2 |    "uri": "http://<ingress_hostname>:8080",
3 |    "checkSslValidity": false
4 |  }
```
Save the changes.
Open the Task Manager and restart the OpeniTRegistrar service.
