Apache download

  • Linux CentOS, RedHat 
    # yum install httpd
  • Linux Debian, Ubuntu 
    # apt-get install httpd

Apache configuration

Apache start / restart

    Command depends on Apache version, one of these should work: 
    # apachectl restart
# /opt/freeware/apache/sbin/apachectl restart
# /etc/init.d/httpd restart
# service apache2 restart
    If you have firewall enabled then enable LPAR2RRD communication by: 
    # firewall-cmd --add-service=http --permanent
# firewall-cmd --add-service=https --permanent
# firewall-cmd --add-port=8162/tcp --permanent

# firewall-cmd --reload

Test web pages

    Point your web browser to http://<your lpar2rrd host>/lpar2rrd/ as soon as you configure LPAR2RRD
    Do not forget to ensure that Apache starts after the OS reboot (there must be a starting script in /etc/rc.... )

Apache configuration per platform and version

  • Apache 2.4+ generally


    Configure httpd.conf, it might be in different locations (depends of distribution)
    • /etc/httpd/httpd.conf
    • /etc/httpd/conf/httpd.conf
    • /etc/opt/freeware/apache/httpd.conf (AIX)
    • /opt/freeware/etc/httpd/httpd.conf (AIX)
    • /opt/freeware/etc/httpd/conf/httpd.conf (AIX)
    • /etc/apache2/apache2.conf

    1. Verify alias_module and cgi_module is loaded (uncommented it, the path can be different) 
      LoadModule alias_module /opt/freeware/lib/httpd/modules/mod_alias.so
LoadModule cgi_module /opt/freeware/lib/httpd/modules/mod_cgi.so
    2. cgi_module could depend on mpm_prefork_module like here.
      Allow it as well (uncomment it) and disable mpm_worker_module, mpm_event_module 
      LoadModule mpm_prefork_module /opt/freeware/lib/httpd/modules/mod_mpm_prefork.so
# LoadModule mpm_worker_module /opt/freeware/lib/httpd/modules/mod_mpm_worker.so

<IfModule mpm_prefork_module>
     LoadModule cgi_module /opt/freeware/lib/httpd/modules/mod_cgi.so
</IfModule>
    3. Append this at the end of httpd.conf 
      AddHandler cgi-script .sh
Alias /lpar2rrd  "/home/lpar2rrd/lpar2rrd/www/"
<Directory "/home/lpar2rrd/lpar2rrd/www/">

  • SELinux changes


    You need to disable the SELinux service protection to be able to utilize basic web services.
    You must do it in case you get "(13)Permission denied:" in Apache error_log.
    You have 2 options:

    • Disable SELinux only for Apache 
      Step 1. Query for the Boolean value you need to change:
# getsebool -a | grep httpd_dis
  httpd_disable_trans --> off

Step 2. Disable the SELinux protection:
# setsebool -P httpd_disable_trans=1

Step 3. Verify that the Boolean has changed:
# getsebool -a | grep httpd_dis
  httpd_disable_trans --> on
    • Globally disable SELinux 
      # setenforce Permissive
# vi /etc/sysconfig/selinux
  SELINUX=disabled
Oracle DB monitoring schema
LPAR2RRD obtains data through SQL (SQL*Plus). Oracle client must be installed on LPAR2RRD server.
Monitoring implementation does not require any Oracle licensed features like Oracle Diagnostics Pack or Oracle Tuning Pack .
LPAR2RRD requires a database user with the following view only permissions to collect monitoring data:
  • create session
  • select rights on specific sys.* tables

Oracle Instant Client and SQL*Plus installation

Oracle Instant Client and SQL Plus are used for collecting information from an Oracle DB instance.
Oracle DB user is needed with sufficient privileges.
Version compatibility: OIC 19c supports Oracle DB versions 11.2.0.4 and newer.
Oracle Instant Client (OIC) can be deployed from a ZIP file or installed as an RPM package.
Installation steps are performed under root account

  • Linux: libaio prerequisite Skip this step if you are using XoruX Virtual Appliance
    # yum -y install libaio.x86_64
  • Linux CentOS8/RHEL8: libnsl.so.1 might not have been in the OS present, install it: 
    # dnf install libnsl.x86_64
  • Installation form ZIP files (Linux and AIX)
    • AIX: note that Oracle Client packages do not work on AIX 6.1, AIX 7.1 and 7.2 are fine.

    • Download ZIP packages from Oracle Download website Linux x86-64, AIX
      OIC basic: instantclient-basic-linux.x64-19.6.0.0.0dbru.zip
      SQL*Plus: instantclient-sqlplus-linux.x64-19.6.0.0.0dbru.zip

      Create /opt/oracle directory and unzip 
      # umask 022
# mkdir /opt/oracle
# cd /opt/oracle
# unzip /<download_dir>/instantclient-basic-linux.x64-19.6.0.0.0dbru.zip
# unzip /<download_dir>/instantclient-sqlplus-linux.x64-19.6.0.0.0dbru.zip
      ZIP files will be unpacked into /opt/oracle/instantclient_<version>

    • ldconfig (Linux) 
      # echo "/opt/oracle/instantclient_<version>" > /etc/ld.so.conf.d/oracle-instantclient.conf
# ldconfig
  • RPM installation - Linux
  • AIX: missing iocp
    You may get the following err when running sqlplus on AIX.
    # cd /opt/oracle/instantclient_<version>
# export LIBPATH=`pwd`

Connectivity check

Allow access from the LPAR2RRD host to Oracle DB host.
Make sure you are using correct port.
Default port for Oracle DB sessions is 1521.

Check connectivity:
$ perl /home/lpar2rrd/lpar2rrd/bin/conntest.pl 192.168.1.1 1521
  Connection to "192.168.1.1" on port "1521" is ok

Attach Oracle Databases

  • Oracle environment
    Set Oracle environment variables in etc/lpar2rrd.cfg, modify existing setup 
    # Oracle DB client setup
# Adjust ORACLE_HOME & ORACLE_BASE as necessary, "instantclient_X" is only example
# Do not use ORACLE_HOME variable as part of ORACLE_HOME, use always full path!
  ORACLE_BASE=/opt/oracle
  ORACLE_HOME=/opt/oracle/instantclient_XY
    Note ORACLE_HOME must be directory where sqlplus binary is, like in this example when it is in /usr/lib/oracle/19.6/client64/bin/sqlplus 
    ORACLE_BASE=/usr/lib/oracle
ORACLE_HOME=/usr/lib/oracle/19.6/client64/bin
    There can be a problem when sqlplus is in "bin" subdir as such ORACLE_HOME do not have to acceptable for Oracle client.
    Either use ORACLE_HOME without "bin" and copy/symlink sqlplus to ORACLE_HOME or upgrade to LPAR2RRD 7.04+ (release in Dec 2020) where it is fixed (you do not need to put "bin" into ORACLE_HOME)

  • LPAR2RRD UI ➡ Settings icon ➡ Oracle DB --> ➡ New :
    Oracle DB configuration

    Oracle service: to list Oracle service use this cmd on the server where DB is running: lsnrctl status
    Make sure that connection test passes without errors or warnings.

  • Number of attached Oracle RAC instances is limited to 1 in the Free edition.
    However you can attach Oracle RAC nodes even as stand-alone instances if you reach the limitation, there is no limit for attaching of Oracle stand-alone DB instances.

  • Make sure cron jobs for Oracle DB are in place (upgrade script might do it for you automatically)
    Skip this step if you install the Virtual Appliance - it is already taken care of. 
    $ crontab -l | grep "load_oracledb.sh"
$
    Add following lines to crontab if necessary 
    $ crontab -e

# Oracle DB support
0,5,10,15,20,25,30,35,40,45,50,55 * * * *  /home/lpar2rrd/lpar2rrd/load_oracledb.sh > /home/lpar2rrd/lpar2rrd/load_oracledb.out 2>&1
  • Wait 30 minutes and then go to the web UI: http://<your web server>/lpar2rrd/
    Use Ctrl-F5 to refresh the web browser cache.


Skip it in case of configuring Virtual Appliance

Install LPAR2RRD server

  • Download the latest LPAR2RRD server
    Upgrade your already running LPAR2RRD instance.

  • Install it: 
    # su - lpar2rrd
$ tar xvf lpar2rrd-7.XX.tar
$ cd lpar2rrd-7.XX
$ ./install.sh
$ cd /home/lpar2rrd/lpar2rrd
  • Schedule to run it from lpar2rrd crontab (it might already exist there)
    $ crontab -l | grep load.sh
$
    Add if it does not exist as above 
    $ crontab -e

# LPAR2RRD UI
0 * * * * /home/lpar2rrd/lpar2rrd/load.sh > /home/lpar2rrd/lpar2rrd/load.out 2>&1
    Assure there is just one such entry in crontab.

  • You might need to add lpar2rrd user into /var/adm/cron/cron.allow if crontab command fails
    Allow it for lpar2rrd user as root user. 
    # echo "lpar2rrd" >> /var/adm/cron/cron.allow
  • Assure you have a cron jobs for Oracle DB in place (upgrade script might do it automatically) Skip it on the Virtual Appliance, it is already there. 
    $ crontab -l | grep "load_oracledb.sh"
