There are several steps to install the server.
Step 1. Open the command line on the server. Then, run the following command:
curl -fsSL -o get_elma365.sh https://dl.elma365.com/standard/master/install.sh && chmod +x get_elma365.sh && ./get_elma365.sh
You can increase the installation timeout if necessary. Set the value for 120 minutes, for example.
TIMEOUT=120m ./get_elma365.sh
Step 2. Enter the Administrator password (root).
Step 3. Enter base-URL – local domain name or the server IP address. ELMA365 will be available at this IP address.
Step 4. Enter the main administrator login (email).
Step 5. Enter the main administrator password.
Next, you can set up an smtp server for email messaging. Skip this step if you want to configure the smtp server later. You can find it in the Administration workspace.
Step 6. Set up an smtp server:
- SMTP host. Enter the server address according to your email server settings. For example, smtp.gmail.com.
- SMTP port. Enter the connection port according to your email server settings. For example, 465.
- Select the SSL. For example, TLS.
- From address. Specify the address you want to use to send messages.
- SMTP password. Specify the server password.
The installation process takes up 10-15 minutes. If the program is installed successfully, the following message will appear: ELMA365 successfully installed. Visit http:/.... [Step 3 server IP address].
The installation log files are located in /var/log/elma365/install.log. If you are experiencing problems installing ELMA365, consult the log files to troubleshoot the installation.
