Installing Amplia on Oracle Linux
To install an on-premises instance of Amplia on Oracle Linux, follow the steps below. For other platforms, click here.
Tip
Before you start, make sure you have completed the steps outlined on Planning before installation
Prerequisites
- Oracle Linux 7.x
- PKI SDK license (in Base64 format)
- Web PKI license (Base64/binary format) -- only needed if users will issue certificates on their computers (web issuing procedure)
- DNS entries previously created for:
- Dashboard access (see Dashboard domain)
- CRL publishing (see Access domains)
- Connection string to a previously created SQL Server or PostgreSQL database
Install the ASP.NET Core Runtime 3.1
Important
These instructions assume you are logged in as root. If you are not, run sudo su - before continuing!
Register the Microsoft key and package repository (this only needs to be done once per machine), then install the ASP.NET Core runtime package:
rpm -Uvh https://packages.microsoft.com/config/rhel/7/packages-microsoft-prod.rpm
yum install aspnetcore-runtime-3.1
To test the installation, run:
dotnet --list-runtimes
The expected output is similar to:
Microsoft.AspNetCore.App 3.1.x [/usr/share/dotnet/shared/Microsoft.AspNetCore.App]
Microsoft.NETCore.App 3.1.x [/usr/share/dotnet/shared/Microsoft.NETCore.App]
Tip
For alternative ways to install the ASP.NET Core Runtime, see this page
Install Amplia
Note
Some steps use the nano command, which might not be installed on your system. Feel free to replace the command by vi or install nano with yum install nano
Create a local user to run the Amplia server:
mkdir /var/amplia
useradd --system --home-dir /var/amplia amplia
chown amplia:amplia /var/amplia
Create the site folder, download and extract the binaries:
Note
To test the next version of Amplia, currently in Release Candidate stage, replace amplia-x.y.z.tar.gz on the following commands
with amplia-4.9.0-rc05.tar.gz. Beware: Release Candidate versions are not production-ready and thus should only be installed on staging or test environments!
mkdir /usr/share/amplia
curl -O https://cdn.lacunasoftware.com/amplia/amplia-4.8.0.tar.gz
tar xzf amplia-4.8.0.tar.gz -C /usr/share/amplia
chmod -R a=,u+rwX,go+rX /usr/share/amplia
Note
Site binaries can be read by any user and can only be changed by root users. This means that the application user (amplia) can read but not change the files, which is intentional.
Create the configuration file from the given template:
mkdir /etc/amplia
cp /usr/share/amplia/config-templates/linux/appsettings.conf /etc/amplia/
chown -R root:amplia /etc/amplia
chmod -R a=,u+rwX,g+rX /etc/amplia
Note
Configuration files can only be read by members of the amplia group and can only be changed by the root user. This is important to protect sensitive data stored on the configuration files from unauthorized access.
Configure Amplia
Edit the configuration file to configure your Amplia instance:
nano /etc/amplia/appsettings.conf
On the [General] section, to fill the EncryptionKey setting generate a 256-bit key to encrypt sensitive data stored on the database:
openssl rand -base64 32
Also on the [General] section, to fill the RootPasswordHash setting choose a strong password for root access to the dashboard and hash it:
dotnet /usr/share/amplia/Lacuna.Amplia.Site.dll -- hash-root-pass
Note
If you wish to enable user management, leave the RootPasswordHash setting blank and follow the steps on Configure OpenID Connect instead
Fill the remaining settings according to the instructions on the configuration file.
Set up a daemon
Create the service definition file:
touch /etc/systemd/system/amplia.service
nano /etc/systemd/system/amplia.service
Enter the following:
[Unit]
Description=Amplia
[Service]
WorkingDirectory=/usr/share/amplia
ExecStart=/usr/bin/dotnet Lacuna.Amplia.Site.dll
Restart=always
RestartSec=10
KillSignal=SIGINT
SyslogIdentifier=amplia
User=amplia
Environment=ASPNETCORE_ENVIRONMENT=Linux
Environment=DOTNET_PRINT_TELEMETRY_MESSAGE=false
[Install]
WantedBy=multi-user.target
Save the file, then enable the service and start it:
systemctl enable amplia
systemctl start amplia
systemctl status amplia
The expected output is similar to:
* amplia.service - Amplia
Loaded: loaded (/etc/systemd/system/amplia.service; enabled; vendor preset: enabled)
Active: active (running) since Sun 2019-07-07 05:50:04 UTC; 4min 22s ago
Main PID: 10960 (dotnet)
Tasks: 31 (limit: 2319)
CGroup: /system.slice/amplia.service
└─10960 /usr/bin/dotnet Lacuna.Amplia.Site.dll
...
Dec 04 12:45:08 server.patorum.com amplia[32562]: Hosting environment: Production
Dec 04 12:45:08 server.patorum.com amplia[32562]: Content root path: /usr/share/amplia
Dec 04 12:45:08 server.patorum.com amplia[32562]: Now listening on: http://localhost:5000
Dec 04 12:45:08 server.patorum.com amplia[32562]: Application started. Press Ctrl+C to shut down.
Hint: Some lines were ellipsized, use -l to show in full.
If necessary, restart the service: systemctl restart amplia
To test that the Amplia server is running, run:
curl http://localhost:5000/api/system/info
The expected output is something like:
{"productName":"Lacuna Amplia","productVersion":"4.x.x","spaVersion":"...","timestamp":"..."}
Set up a reverse proxy server
Note
If you prefer to use Apache instead of Nginx, see this article.
Install Nginx (if not already installed):
rpm -Uvh http://nginx.org/packages/rhel/7/noarch/RPMS/nginx-release-rhel-7-0.el7.ngx.noarch.rpm
yum install nginx
systemctl enable nginx.service
systemctl start nginx.service
Test that Nginx is running:
curl -I http://localhost/
Check the first lines of the output, which should be similar to:
HTTP/1.1 200 OK
Server: nginx/...
...
Disable the default Nginx site:
rm /etc/nginx/conf.d/default.conf
Create a site configuration file for Amplia:
touch /etc/nginx/conf.d/amplia.conf
nano /etc/nginx/conf.d/amplia.conf
Enter the following, replacing the dashboard domain on the server_name entry (see Dashboard domain):
server {
listen 80;
server_name localhost ca.patorum.com;
location / {
proxy_pass http://localhost:5000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
Tip
Ideally, your site configuration should contain the entries ssl_certificate and ssl_certificate_key with a valid SSL certificate. This configuration is outside of the scope of these instructions.
Allow Nginx to access the Amplia service:
setsebool -P httpd_can_network_connect on
Test the Nginx configuration and reload it:
nginx -t
nginx -s reload
Test the site:
curl http://localhost/api/system/info
Allow HTTP and HTTPS traffic to your system (if not already allowed):
firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --zone=public --add-port=443/tcp --permanent
firewall-cmd --reload
