Chapter 9. Troubleshooting IdM server installation The following sections describe how to gather information about a failing IdM server installation, and how to resolve common installation issues. 9.1. Reviewing IdM server installation error logs When you install an Identity Management (IdM) server, debugging information is appended to the following log files: /var/log/ipaserver-install.log /var/log/httpd/error_log /var/log/dirsrv/slapd- INSTANCE-NAME /access /var/log/dirsrv/slapd- INSTANCE-NAME /errors The last lines of the log files report success or failure, and the ERROR and DEBUG entries provide additional context. To troubleshoot a failing IdM server installation, review the errors at the end of the log files and use this information to resolve any corresponding issues. Prerequisites You must have root privileges to display the contents of IdM log files. Procedure Use the tail command to display the last lines of a log file. The following example displays the last 10 lines of /var/log/ipaserver-install.log . To review a log file interactively, open the end of the log file using the less utility and use the ^ and v arrow keys to navigate. The following example opens the /var/log/ipaserver-install.log file interactively. Gather additional troubleshooting information by repeating this review process with the remaining log files. Additional resources If you are unable to resolve a failing IdM server installation, and you have a Red Hat Technical Support subscription, open a Technical Support case at the Red Hat Customer Portal and provide an sosreport of the server. The sosreport utility collects configuration details, logs and system information from a RHEL system. For more information about the sosreport utility, see the Red Hat Knowledgebase solution What is an sosreport and how to create one in Red Hat Enterprise Linux? . 9.2. Reviewing IdM CA installation errors When you install the Certificate Authority (CA) service on an Identity Management (IdM) server, debugging information is appended to the following locations (in order of recommended priority): Location Description /var/log/pki/pki-ca-spawn. USDTIME_OF_INSTALLATION .log High-level issues and Python traces for the pkispawn installation process journalctl -u pki-tomcatd@pki-tomcat output Errors from the pki-tomcatd@pki-tomcat service /var/log/pki/pki-tomcat/ca/debug. USDDATE .log Large JAVA stacktraces of activity in the core of the Public Key Infrastructure (PKI) product /var/log/pki/pki-tomcat/ca/signedAudit/ca_audit log file Audit log of the PKI product /var/log/pki/pki-tomcat/ca/system /var/log/pki/pki-tomcat/ca/transactions /var/log/pki/pki-tomcat/catalina. USDDATE .log Low-level debug data of certificate operations for service principals, hosts, and other entities that use certificates Note If a full IdM server installation fails while installing the optional CA component, no details about the CA are logged; a message is logged in the /var/log/ipaserver-install.log file indicating that the overall installation process failed. Review the log files listed above for details specific to the CA installation failure. The only exception to this behavior is when you are installing the CA service and the root CA is an external CA. If there is an issue with the certificate from the external CA, errors are logged in /var/log/ipaserver-install.log . To troubleshoot a failing IdM CA installation, review the errors at the end of these log files and use this information to resolve any corresponding issues. Prerequisites You must have root privileges to display the contents of IdM log files. Procedure To review a log file interactively, open the end of the log file using the less utility and use the ^ and v arrow keys to navigate, while searching for ScriptError entries. The following example opens /var/log/pki/pki-ca-spawn. USDTIME_OF_INSTALLATION .log . Gather additional troubleshooting information by repeating this review process with all the log files listed above. Additional resources If you are unable to resolve a failing IdM server installation, and you have a Red Hat Technical Support subscription, open a Technical Support case at the Red Hat Customer Portal and provide an sosreport of the server. The sosreport utility collects configuration details, logs and system information from a RHEL system. For more information about the sosreport utility, see the Red Hat Knowledgebase solution What is an sosreport and how to create one in Red Hat Enterprise Linux? . 9.3. Removing a partial IdM server installation If an IdM server installation fails, some configuration files can be left behind. Additional attempts to install the IdM server fail and the installation script reports that IPA is already configured. Example system with existing partial IdM configuration To resolve this issue, uninstall the partial IdM server configuration and retry the installation process. Prerequisites You must have root privileges. Procedure Uninstall the IdM server software from the host you are trying to configure as an IdM server. If you continue to experience difficulty installing an IdM server because of repeated failed installations, reinstall the operating system. One of the requirements for installing an IdM server is a clean system without any customization. Failed installations may have compromised the integrity of the host by unexpectedly modifying system files. Additional resources For additional details on uninstalling an IdM server, see Uninstalling an IdM server . If installation attempts fail after repeated uninstallation attempts, and you have a Red Hat Technical Support subscription, open a Technical Support case at the Red Hat Customer Portal and provide an sosreport of the server. The sosreport utility collects configuration details, logs and system information from a RHEL system. For more information about the sosreport utility, see the Red Hat Knowledgebase solution What is an sosreport and how to create one in Red Hat Enterprise Linux? . 9.4.
