4 Installing the RUEI Software

This chapter describes the procedure for installing the Apache Web server and RUEI software. The procedure for upgrading an existing RUEI 4.5.x installation to release 5.0 is also described. The post-installation configuration procedure is described in Chapter 6, "Configuring RUEI".

4.1 Obtaining the RUEI Software

The RUEI software is available from the Oracle E-Delivery Web site ( Select the following media pack criteria:

4.2 Unpacking the RUEI Software

Copy the downloaded RUEI zip file to /root directory on the server, and unzip it. Use the following commands:

cd /root

The following directories are created which contain the software needed to complete the RUEI installation:

4.3 Generic Installation Tasks

All steps described in this section must be performed regardless of your planned installation (that is, a Reporter with local database, a Reporter with remote database, or a Collector).

4.3.1 The RUEI Configuration File

If you are planning an installation using the default installation location and users, you can use the default settings in the /etc/ruei.conf file. If you are not planning to use the default installation directories, operating system users and groups, it is recommended that you carefully review the settings in this configuration file and adapt them to your needs. All components in your RUEI environment (such as the remote database and Collectors) require the same global ruei.conf configuration file. The following settings are specified:

Table 4-1 RUEI Settings.

Setting DescriptionFoot 1  Default value

RUEI_HOMEFootref 2

Home directory of the RUEI software.



Directory for RUEI data files.



The RUEI operating system user.



The RUEI operating system group.



The database instance name.



The database user name.



The database connect string.


Footnote 1 Be aware that all variables specified in this table are the defaults used throughout this guide, and can be modified as required.

Footnote 2 The directory name cannot exceed 50 characters in length.

Footnote 3 The directory name cannot exceed 8 characters in length.

Footnote 4 The directory name cannot exceed 30 characters in length.

Footnote 5 The directory name cannot exceed 255 characters in length.

There is no need to change the settings for JAVA_HOME and INSTANTCLIENT_DIR if you intend to use the software contained on the RUEI distribution pack.

  1. Create the moniforce group and user. The home directory of moniforce should be set to /var/opt/ruei, with read permissions for group members.

    /usr/sbin/groupadd moniforce
    /usr/sbin/useradd moniforce -g moniforce -d /var/opt/ruei
    chmod -R 750 /var/opt/ruei
    chown -R moniforce:moniforce /var/opt/ruei
  2. An example of the configuration file is included in the RUEI distribution pack. Ensure the file is readable by the RUEI_USER (default moniforce) user by issuing the following commands:

    cp /root/RUEI/extra/ruei.conf /etc/
    chmod 644 /etc/ruei.conf
    chown moniforce:moniforce /etc/ruei.conf

In case of a remote database installation, the ruei.conf file needs to be identical with that of the Reporter system.

4.3.2 Installing Java

For both Reporter and Collector systems you need to install the Java Runtime Environment (JRE). Java is bundled within the RUEI distribution pack.

  1. Issue the following commands:

    cd /root/RUEI/Java
    chmod +x ./jre-1_5_0_18-linux-amd64-rpm.bin

    Note you are prompted to accept the Java licence agreement. You cannot continue until you have done so.

  2. This installs the necessary Java software in the directory /usr/java/jre1.5.0_18. To make the install directory version independent, create a more generic symlink using the following command:

    ln -s /usr/java/jre1.5.0_18 /usr/java/jre

4.4 Remote Collector Installation

This section can be skipped for Reporter or remote database servers.

Logon to the Collector system as the root user, and do the following:

  1. The RUEI file and directory locations are fixed. Therefore, it is necessary to use the exact directory name described below. Create the RUEI application root directory using the following command:

    mkdir -p /opt/ruei
  2. Change to the RUEI root directory and run the script using the following commands:

    cd /root/RUEI/51
    chmod +x
    ./ collector
  3. In addition to the actions described above, you need to configure the network interfaces. This is fully described in Section 4.6, "Configuring the Network Interface". Moreover, you also need to setup a passwordless remote login from the Reporter system to the newly created Collector system. The necessary configuration steps are described in Section 4.11, "Configuring Reporter Communication (Split-Server Setup Only)".

4.5 Reporter Installation

This section describes the procedure for installing the required components for a Reporter system. These include the Apache Web server, the Oracle database Instant Client, and the Zend Optimizer.

4.5.1 Installing the Apache Web Server and PHP

This section describes the installation and configuration of the Apache Web server, and the components that use it. PHP Configuration

  1. Ensure that the Web server starts automatically after re-boot by issuing the following command:

    /sbin/chkconfig httpd on
  2. Edit the /etc/sysconfig/httpd file to include the following line at the bottom of the file:

    source /etc/ruei.conf
  3. Create the following settings in the /etc/php.d/ruei.ini file:

    session.gc_maxlifetime = 14400
    memory_limit = 96M
    upload_max_filesize = 128M
    post_max_size = 128M Avoiding rsvg Warnings

RUEI uses rsvg for graph generation. In order to avoid warnings about a missing directory, create the empty .gnome2 directory using the following command:

mkdir -p /var/www/.gnome2

4.5.2 Installing the Oracle Database Instant Client

Install the Oracle database Instant Client and SQLplus extension with the following commands as the root user:

cd /root/RUEI/IC
rpm -Uhv oracle-instantclient11.1-basic-*.rpm
rpm -Uhv oracle-instantclient11.1-sqlplus-*.rpm

4.5.3 Installing the php-oci8 Module

Install the php-oci8 module (this is part of the RUEI distribution set) using the following commands:

cd /root/RUEI/PHP
rpm -Uhv php-oci8-11gR1-*

4.5.4 Installing the Zend Optimizer

Go to the directory containing the Zend Optimizer code, unpack the tar file, and run the Zend optimizer installer. Read the license agreement. You will not be able to proceed until you have accepted the license terms. Accept all default settings, and allow the installer to restart the Apache Web server. Issue the following commands:

cd /root/RUEI/ZendOptimizer
tar zxvf ZendOptimizer-3.3.3-linux-glibc23-x86_64.tar.gz
cd ZendOptimizer-3.3.3-linux-glibc23-x86_64


If you upgrade your system packages (for example, using Yum), this can overwrite changes you previously made to the /etc/php.ini file. Therefore, you should be prepared to re-install the Zend Optimizer. When doing so, ensure the Zend Optimizer installer indicates the location of the php.ini file as /etc/php.ini and not /usr/local/Zend/etc/php.ini.

Additional Information

It is recommended you add the Zend configuration lines created in the /etc/php.ini file to the RUEI-specific PHP configuration file /etc/php.d/ruei.ini to prevent upgrade issues. If you performed a default installation of the Zend Optimizer, this involves copying the following lines:



4.5.5 Creating the RUEI Database Instance

The RUEI database can reside either locally (that is, on the Reporter server) or on a remote database server. In this section you will create the database instance required for RUEI, and generate the "connection data" required for the Reporter to connect to this database instance.

You will need the following scripts to be present on the system where the database instance (RUEI_DB_INST) will be created:

  • ~/ creates the database instance, Oracle wallet and database connect files.

  • ~/ a hardware and environment check utility, and is automatically invoked by The script can also be used as a stand-alone troubleshooting utility. A complete description of the script, refer to Appendix A, "The Script".

The four "connection data" files created during the procedure described in this section are as follows:

  • cwallet.sso

  • ewallet.p12

  • sqlnet.ora

  • tnsnames.ora

The RUEI configuration file (/etc/ruei.conf) also needs to be present on the database server and configured as described in Section 4.3.1, "The RUEI Configuration File".

Do the following:

  1. Copy the ~/ and ~/ scripts to the server on which you intend to run the database instance, and make them executable for the oracle user. These scripts can be found in the RUEI distribution zip (/root/RUEI/51).

  2. Review the settings in the /etc/ruei.conf file to match your needs as described in Section 4.3.1, "The RUEI Configuration File".

  3. Logon to the database server as the oracle user on the database server, and set the ORACLE_HOME environment variable. You need to run the script as the oracle user. This script creates the RUEI_DB_INST database, but only after a number hardware and software environment checks have been performed. The actual checks performed depend on the system type you are currently installing.

    The script prompts you for the RUEI database user password, and the password used to protect the Oracle wallet. Once the wallet password is stored in a secure location, the RUEI application can login to the database automatically. The script also creates the "connection data" files for you now.

    If you run the script for a combined Reporter/Database server, all files are placed automatically in the correct location. In case of a remote database, a separate .tar file is generated, and you will need to perform the extra step 4.

    Issue the following commands:

    chmod +x
    export ORACLE_HOME=/u01/app/oracle/product/11.1.0/db_1

    If you ran the above commands on a combined Reporter/Database server you can skip step 4 and proceed to step 5.

  4. This step only applies when using a remote database.

    In the case of a Reporter system using a remote database, you will need to copy the generated /tmp/ruei-database-configuration.tar file in step 3 from the database server to the Reporter system. The /tmp/ruei-database-configuration.tar file must be extracted on Reporter server in the directory /var/opt/ruei (RUEI_DATA). The permissions of the files need to be set so that the specified RUEI_USER (moniforce) can use them.

    Copy the generated .tar file, which holds connection data files to the Reporter system. Logon to the Reporter server and extract the .tar file using the following commands:

    cd /var/opt/ruei
    tar xvf path-to-tar-file/ruei/database-configuration.tar
    chown moniforce:moniforce cwallet.sso ewallet.p12 sqlnet.ora tnsnames.ora
  5. Because logging of the database can consume a large amount of disk space, it is recommended you install a clean-up script to avoid the usage of unnecessary disk space. Copy the (example) script to the oracle user directory and activate it via cron using the following commands:

    mkdir -p /home/oracle/bin
    cp /root/RUEI/extra/ /home/oracle/bin
    chmod +x /home/oracle/bin/
    su - oracle -c 'echo "10 0 * * * /home/oracle/bin/" | crontab'

4.5.6 Installation of the Reporter Software

  1. The RUEI directory locations are flexible. Therefore, it is necessary to use the exact directory name described as configured in the /etc/ruei.conf file. Create the RUEI application root directory using the following command:

    mkdir -p /opt/ruei


    The specified RUEI_HOME and RUEI_DATA directories must have 750 permissions defined for them.
  2. Make the apache and moniforce members of two additional groups using the following commands:

    /usr/sbin/usermod -aG moniforce apache
    /usr/sbin/usermod -aG uucp apache
    /usr/sbin/usermod -aG uucp moniforce
  3. Go to the directory which holds the RUEI software, and install the RUEI packages. You can specify reporter or collector to the script depending on the required installation:

    cd /root/RUEI/51
    chmod +x
    ./ reporter
  4. Re-start the Apache Web server using the following command:

    /sbin/service httpd restart
  5. Verify that the RUEI software was correctly installed by issuing the following command:

    ./ postinstall
  6. As the moniforce user, set the RUEI Administration password to enable logging onto the RUEI interface with the following commands:

    su - moniforce

    You are prompted to enter and confirm the password.


    When defining the Administrator password, bear the following in mind:
    • The password must have at least eight characters, and contain at least one non-alphanumeric character (such as $, @, &, and !).

    • The initial password must be changed within seven days.

    • The user name and password are case sensitive.

4.6 Configuring the Network Interface

This section is only relevant to Reporter and Collector systems.

Make the monitoring network interface up status permanent (after a reboot) by setting the ONBOOT parameter of the capturing interfaces to yes in the interface configuration files. The network interfaces configuration can be found in /etc/sysconfig/network-scripts/ifcfg-ethX (where X represents the necessary network interface). Alternatively, use the graphical utility system-config-network to set the appropriate interfaces to "activate device when computer starts".

4.7 Enabling Multibyte Fonts (Optional, but Recommended)

This section is only relevant to the Reporter system.

For PDF generation with multibyte character content, additional fonts need to be enabled. These fonts need to be made available to Java. Use the following command to copy (or move) the RUEI-installed fonts to the appropriate Java directory:

cp /opt/ruei/gui/include/bi_publisher/fonts/* \

4.8 Mail (MTA) Configuration (Optional, Reporter Only)

This section is only relevant to the Reporter system.

RUEI assumes a working local MTA for sending PDF reports and E-mail alerts. By default, Enterprise Linux uses the Sendmail MTA. By default, Sendmail will deliver the E-mail directly to the destination MTA. If this behavior is not according to your needs or policies, sending mail via a SmartHost (relay) might be an alternative. To configure a SmartHost in Sendmail, do the following:

  1. Install the Sendmail configuration utility by issuing the following command:

    rpm -Uhv sendmail-cf-8.13.8-2.el5.x86_64.rpm
  2. Find the line which contains the Smart Host setting in /etc/mail/ Modify the SMART_HOST setting to your needs. For example:

    define('SMART_HOST', 'my.example')dnl
  3. Generate the new configuration into a new by executing the following command:

    make -C /etc/mail
  4. Restart Sendmail. For example:

    /etc/init.d/sendmail restart 


Extensive information about the configuration of the Sendmail MTA is available at

4.9 SNMP (Reporter Only)

You can download the RUEI MIB definition file through the Reporter interface. This definition file can be added to the SNMP manager. The procedure for downloading the MIB file is described in the Oracle Real User Experience Insight User's Guide.

4.10 Configuring Automatic Browser Redirection (Optional)

This section is only relevant to Reporter systems with a remote Collector.

To have the browser automatically redirected to the correct RUEI path, create the file /var/www/html/index.html with the following content:

                   <meta http-equiv="REFRESH" content="0;URL=/ruei/">

4.11 Configuring Reporter Communication (Split-Server Setup Only)

This section is only relevant to a Reporter system with remote Collector(s).

A password-less SSH connection must be setup between the Moniforce user from the Reporter system to each Collector system. Do the following:

  1. Logon to the Reporter server as root. Issue the following commands:

    su - moniforcessh-keygen -P ""

    Press Enter to accept the defaults.

  2. Logon as root on each of the Collector systems. Issue the following commands:

    su - moniforcecd ~/.sshssh root@Reporter cat /var/opt/ruei/.ssh/ >> authorized_keys 

    (you will need to specify the Reporter system root password)

    chmod 600 authorized_keys
  3. Check that it is now possible to execute a remote command (as moniforce user) on the Reporter system without using a password. For example:

    • Logon as root on the Reporter server.

    • Logon as moniforce user: su - moniforce.

    • Execute a remote pwd command: ssh Collector pwd.

    • Enter yes to the question "Are you sure you want to continue connecting (yes/no)?".

    • The command should return /var/opt/ruei.

  4. The above steps must be performed for each Collector!


    If the connection between the Reporter and the Collector(s) has not been correctly configured, you will receive an authorization error when you try to register the remote Collector.

4.12 Verifying Successful Installation of RUEI

On completion of the Initial Setup Wizard (described in Section 6.2, "Performing Initial RUEI Configuration"), you can verify your installation by selecting System, the Status. All system indicators should report OK. Note Status notification will indicate "Unknown" because no system alerts have yet been configured. This is fully described in the Oracle Real User Experience Insight User's Guide.
