Install the bootstrap utility. This can be downloaded from the GitHub repository.
curl https://raw.githubusercontent.com/apisnetworks/apnscp-bootstrapper/master/bootstrap.sh | bash
This arms apnscp with a 15 day license (60 day for development releases). If you have purchased a license via my.apnscp.com, then the license may be provided at install by providing the token:
curl https://raw.githubusercontent.com/apisnetworks/apnscp-bootstrapper/master/bootstrap.sh | bash -s - <api token>
Before the bootstrap utility kicks off stage 2, you are given an opportunity to pause to edit variables. This is optional, but will allow you to immediately configure SSL. These values can be changed later with
config_set in the panel.
Bootstrapper is an idempotent tool to continuously update and correct your server. If things drift, Bootstrapper is designed to provide the minimal set of enforcing changes to make your server work. You will always have free rein of your server as long as it doesn't impede upon the responsibility of apnscp.
Bootstrapping takes between 60 - 120 minutes depending upon provider capacity. Generally lower figures indicate a less oversold provider, but times can change as clients are housed on the server. Once installed, be sure to log out of the server and log back in or load a new shell with the correct apnscp environment,
exec $SHELL -i
Recommended configuration settings
Bootstrapper can run without any changes to
/root/apnscp-vars.yml. The following changes are recommended to make setup seamless. These settings are configured when the bootstrap utility pauses:
- apnscp_admin_email: (email address) used to set besthe admin contact. Also notified when apnscp is installed (FQDN required). This email address is used as your Let's Encrypt admin contact.
- ssl_hostnames: (list or string) hostnames that resolve to this server that should be considered for Let's Encrypt SSL issuance.
- has_low_memory: (true/false) disables auxiliary services for 2 GB instances. See low-memory mode below.
- user_daemons: (true/false) opens up ports 40000-49999/tcp + udp on the server for accounts that want to run a service. If you're running strictly PHP/Node/Python/Ruby services, turn this off for added security.
- mail_enabled: (true/false) if using GMail or a third-party email provider disables IMAP/POP3 + ESMTPA. Mail can still originate from the server (PHP mail()), but blocks ingress.
- passenger_enabled: (true/false) disable building Passenger + accompanying Ruby/Python interpreters if running a purely PHP mix. Node/npm/yarn is still available, but can't serve websites.
- mysqld_per_account_innodb: (true/false) places tables + data in an aggregate InnoDB pool for higher performance or per account for resource enforcement. An account over quota can cause a cyclic crash in MySQL/MariaDB 5.0+ on recovery. You have been warned. Ensure Argos is setup if enabled.
- data_center_mode: (true/false) ensure all resources that apnscp can account for are accounted. Also enables the pernicious bastard
Setting FQDN for SSL/Email
All servers should have a fully-qualified domain name (FQDN). Failure to have one will cause email to fail, including the installation notice. Moreover, Let's Encrypt will fail issuance. A FQDN must at least contain 1 dot:
- ✅ apnscp.com
- ✅ cdn.bootstrap.org
- ✅ x.y.z.abc.co.uk
- ❌ centos-s-1vcpu-2gb-nyc1-01 (no period/dot)
Set your hostname with,
hostnamectl set-hostname MYHOSTNAME
Where MYHOSTNAME is your hostname for the machine. For consistency reasons, it is required that this hostname resolves to the IP address of the machine and vice-versa with FCrDNS. Check with your DNS provider to establish this relationship.
Once apnscp is setup it can be reconfigured anytime with,
config_set net.hostname MYHOSTNAME
SSL will automatically reissue as well as impacted services restart.
In the event of failure, Bootstrapper can be easily restarted from the command-line,
cd /usr/local/apnscp/resources/playbooks ansible-playbook bootstrap.yml
Network connectivity is a common failure that can be caused by transient errors either in DNS resolution, which is unreliable by UDP protocol design, or network congestion. Network tasks use a built-in retry/wait algorithm to reduce the risk of failure - up to 3 retries with a 5 second wait in between attempts.

The above fragment failed to download a repository off GitHub indicating possible DNS issues with the resolver configured on the machine. Replace the configured resolver with a reliable public DNS resolver (Google, Level3, Cloudflare) by editing
/etc/resolv.conf. Remove all instances of
nameserver and change the DNS timeout which defaults at 5 seconds. When using multiple nameservers,
rotate in the
options directive will round-robin resolvers to distribute lookups across all nameservers.
List of public DNS servers
# Generated by NetworkManager search apisnetworks.com nameserver 184.108.40.206 nameserver 220.127.116.11

Domains that have a properly qualified FQDN will receive notification once apnscp is installed. If not, the admin username/password/contact can be reconfigured at anytime using apnscp's API helper.
cpcmd auth_change_username NEWUSER cpcmd auth_change_password NEWPASSWORD cpcmd common_set_email NEW@EMAIL.COM
Setting all 3 will allow you to login to your new panel at http://IPADDRESS:2082/. If SSL has been setup, or you can trust a bespoke certificate, then use https://IPADDRESS:2083/. When logging in as admin, leave the domain field blank.
Adding your first domain
After logging into the panel as admin, visit Nexus. Services can be reconfigured within Nexus or from the command-line.
AddDomain creates a site from command-line. Multiple parameters can be provided to alter the services assigned to an account. Nexus within the Administrative panel is a frontend for this utility.
admin_add_site is the backend API call for this command-line utility.
AddDomain -c siteinfo,domain=mydomain.com -c siteinfo,admin_user=myadmin
Creates a new domain named mydomain.com with an administrative user myadmin. The email address defaults to firstname.lastname@example.org and password is randomly generated.
Domains may be edited by clicking the SELECT button in Nexus.
EditDomain is a helper to change account state without removing it. You can toggle services and make changes in-place in a non-destructive manner. More advanced usage is available in the blog post, Working with CLI helpers.
Rename domain A simple, common situation is to alter the primary domain of an account. Simply changing the domain attribute under the siteinfo service will accomplish this.
EditDomain -c siteinfo,domain=newdomain.com mydomain.com
Changing password Changing the password is another common operation:
EditDomain -c auth,tpasswd=newpasswd site12
Logging into services
apnscp uses username@domain notation to log into all services. This allows for multiple domains to share the same username without conflict. The only restriction is that the primary account username must be unique.
Unless the domain is explicitly required, such as when logging into the control panel or accessing MySQL remotely use
# to join the username + domain. For example, when logging into SSH as user
example.com, all are acceptable variations of ssh:
ssh -l email@example.com bar.com ssh firstname.lastname@example.org@bar.com ssh -l foo#bar.com bar.com ssh email@example.com
This can be further simplified by creating a file called
~/.sshwith the following lines,
Host bar HostName bar.com User foo#bar.com
ssh bar will login to "bar.com" using the login "foo#bar.com".
As a second example, consider FTP. With the username
myadmin + domain
mydomain.com, the following configuration will allow access to the FTP server using explicit SSL (FTPES).
SFTP is supported if SSH is enabled for the account. ftp.
apnscp can be configured to automatically update itself every night using
cpcmd config_set apnscp.nightly-update 1
Alternatively apnscp can be updated manually with
upcp. Playbooks can be run unconditionally using
upcp -b or
upcp -a if
resources/playbooks has changed since last update.
