概要
Before installing Automation Suite, it is good practice to validate the installation prerequisites and infrastructure readiness. You can use the validateUiPathASReadiness.sh
script to evaluate your environment and generate a summary before performing the installation.
Validation | Description |
---|---|
Hardware requirements | Validates that each machine in the cluster meets the hardware requirements. The check takes into account the following aspects: server, agent, or tainted node; online or offline system; single-node evaluation profile or multi-node HA-ready production profile. |
Disk partitioning and configuration | Validates that you properly partitioned and configured the disk. The check takes into account the following aspects: server or agent node; online or offline system; primary or secondary server node. |
SQL Server connectivity | Validates the connectivity to the configured SQL Server and database. The check takes into account the following aspects: connectivity to the SQL Server host (endpoint) on a given endpoint; connectivity to the principal database if create_db is set to true ;create database ( dbcreator ) permissions if create_db is set to true ;create schema ( db_ddladmin ), read (db_datareader ), and write (db_datawriter ) permissions;connectivity to the database when create_db is set to false ;special requirements for each service. For instance, for Insights, the script checks the columnstore index, json support, and whether SQL Server compatibility level is >= 130;connectivity to the database and SQL Server with integrated authentication. |
Server certificate | Checks that the server certificate you provided is valid. The check takes into account the following aspects: the certificate file format is .pem , i.e. Base64-encoded DER certificate;the private key length is at least 2048; Extended Key Usage and TLS Web Server Authentication, required for accessing Automation Suite on iOS devices; Subject Alternative Name for all the required DNS entries; server certificate and private key match; the CA bundle you provided is actually the issuer of the server certificate; the certificate validity is more than 30 days. |
Token-signing certificate | Checks that the token-signing certificate you provided is valid. The check takes into account the following aspects: the certificate is in pfx format;the password for decrypting the certificate is valid; the certificate validity is more than 30 days. |
Proxy | Validates that you properly configure the proxy. The check takes into account the following aspects:https_proxy , http_proxy , and no_proxy are set as environment variables on the machine;the proxy server is reachable. |
Connectivity | Validates that all machines can connect to each other, that all the required URLs are on the firewall allowlist, and more. The check takes into account the following aspects: the FQDN of Automation Suite and the FQDN of all the other subdomains are resolvable from the machine; in an online setup, all the external URLs are reachable from the machine; all servers, agents, and tainted nodes can connect to each other on the required ports; the outbound connections (URLs) are resolvable via all the nameservers present in /etc/resolve.conf ;if any of the URLs is not resolvable via all the nameservers, then at least one nameserver can resolve all the URLs; either the TCP or UDP protocol is allowed; fixed_rke_address is set to port 9345 and 6443 ;a response is issued when a call is made to the FQDN on port 443 . |
System services | Validates that system services are properly configured. The check takes into account the following aspects:nm-cloud-setup.service , nm-cloud-setup.timer , firewalld are disabled;iscsi-initiator-utils is installed and enabled;auditd is properly configured for --backlog_wait_time set as 1 ;logrotate is properly configured. |
Software requirements | Validates that all the required software is installed. If some software is not installed, the install-uipath.sh installer attempts to install it. |
スクリプトを使用してインストールの前提条件を検証する

オフライン インストール
オフライン インストールの場合は、この手順をインターネットと、Automation Suite がデプロイされるエアギャップ マシンの両方にアクセスできるマシンで実行する必要があります。オンラインのマシンから、最初のターゲット マシンにファイルをコピーします。
前提条件スクリプトはインストーラーとともに sf-installer.zip
というアーカイブにパッケージ化されており、サポート ツールはオフライン専用の sf-infra.tar.gz
としてバンドルされています。これらのファイルは、Automation Suite をインストールするすべてのマシンについてレポートを生成するのに必要です。
