• Common error messages and solutions when installing ESET Remote Administrator 6.x on Linux Operating Systems

For more details about installation of ESET Remote Administrator 6.x, please refer to the following sections of the ESET Remote Administrator User Guide:

• Component installation on Linux
• Supported Linux distributions

The installer log of ESET Remote Administrator Server (ERA Server) may be useful for troubleshooting and reporting to ESET technical support. The log file is located at:

/var/log/eset/RemoteAdministrator/EraServerInstaller.log

Error message

Checking database connection ... failure
Error: Admin connection not working. Unable to continue

Solution

1. Verify the presence of your database server (in this example, MySQL is used) on the server and whether database server is running or not:
   
   service mysql status
   
   or
   
   systemctl status mysql
   
   Note: For Red Hat-based distributions and ERA Appliance the MySQL service name is mysqld.
2. Verify that the ODBC driver is installed on the server. If not, install it:
   
   apt-get install unixodbc libmyodbc (Debian, Ubuntu distributions)
   yum install mysql-connector-odbc (CentOS, Red-Hat, Fedora distributions)
   zypper install myodbc-unixodbc (OpenSUSE distributions)
3. Verify the proper configuration of MySQL ODBC driver in /etc/odbcinst.ini.

Error message

Checking database connection ... failure
Error: Database does not support big blocks of data. Unable to continue. Please reconfigure database first.

Solution

1. Add the following content in the [mysqld] section of the MySQL configuration file (usually located in /etc/my.cnf or /etc/mysql/my.cnf):
   
   [mysqld]
   max_allowed_packet=33M
   • Restart the MySQL service when possible:
     
     service mysql restart
     
     or
     
     systemctl restart mysql

Error message

Checking certificate password ... failed
Error checking peer certificate password: NOT_REGULAR_FILE

Solution

Before installing ESET Remote Administrator Agent (ERA Agent), create a new certificate. Also, verify whether you point to the correct location of the certificate (—cert-path= installation parameter).

Error message

When deploying era.war, you may encounter the following tomcat error messages (located in /var/log/tomcat/catalina.DATE.log):

SEVERE: Exception fixing docBase for context [/era]
java.util.zip.ZipException: error in opening zip file

SEVERE: Error waiting for multi-thread deployment of WAR files to complete

Solution

1. Make sure the openjdk package is installed on the server. Always use the latest officially released version of Java (ESET Remote Administrator Web Console requires Java version 7 or later):
   
   apt-get install openjdk-7-jdk (Debian, Ubuntu distributions)
   yum install java-1.8.0-openjdk (Red-Hat, Fedora distributions)
2. Redeploy era.war into the tomcat folder (on some systems the folder name is tomcat7):
   
   cp era.war /var/lib/tomcat/webapps/

Error message
