The following instructions must be performed as root

• Decide what accounts are going to be needed. Assume the account 'cyrus' will have root privileges and be used for operations requiring root. Assume that the monitoring will run under the non-root access account 'iepm'. Both, for purposes of this documentation are assumed to be in group <account group>, iepm. For this example, I will assume that the home directory for the 'cyrus' account is /home/cyrus, and the home directory for the 'iepm' account is /home/iepm. For the sake of consistency between monitoring systems, the account 'iepm' with /home/iepm is strongly recommended.
  Download the complete package and place the source code in the directory /home/iepm/v3src
• The monitoring host has a name. This is referred to as <fully qualified monitoring host name>. e.g. iepm-ncp.ncp.edu.pk or iepm-bw.slac.stanford.edu
• The monitoring host should be given an <aliasname> that starts with 'iepm-bw'. The idea is to hide the real name of the node, but provide it with a name that can recognize its place in the world. This is important. Examples include:

  iepm-bw.twaren.net iepm-bw.cern.ch iepm-bw.snv.ul-org iepm-bw.fzk.de

• If the account mysql:mysql has not been allocated, allocate it by using the following commands:

  groupadd -g 20000 mysql useradd -u 20000 -g mysql mysql

  Normally the account is created itself along with the installation of mysql.

• Make the mysql directory '/home/iepm/mysql'.

  mkdir /home/iepm/mysql chown mysql:mysql /home/iepm/mysql

• Create a configuration file for /etc/my.cnf which MySQL will use when you install the database. Copy the following contents in to my.cnf.

  [mysqld] datadir=/home/iepm/mysql socket=/home/iepm/mysql/mysql.sock port=3306 [mysqld_safe] datadir=/home/iepm/mysql socket=/home/iepm/mysql/mysql.sock port=3306 [mysql.server] datadir=/home/iepm/mysql socket=/home/iepm/mysql/mysql.sock port=3306 [client] socket=/home/iepm/mysql/mysql.sock port=3306

• If mysql is already running, it is running with the 'test' database. Kill the mysql daemons.
  Restart MySQL with mysqld_safe &. This will restart the MySQL server with the configuration file /etc/my.cnf.
• Create the data base by executing mysql_install_db.
• Change the ownership of /home/iepm/mysql by the command chown chown -R mysql:mysql /home/iepm/mysql.
• Set the database root password with the following command.

  mysqladmin -u root password <new password>

• You are now ready to create the directories with /home/iepm/mysql that must be owned by the iepm account. These directories are used by the iepm monitoring to track the state of the monitoring system. Execute the following commands with 'iepm:iepm' with 'iepm' replaced by the appropriate group for the 'iepm' account. i.e. it would be iepm:< youraccountgroup> in your case.

  # The data directory is where the results from the probes are stored. # These files are picked up by the 'load-datad' daemon and put into the database tables. mkdir /home/iepm/mysql/data chown iepm:iepm /home/iepm/mysql/data # the logs directory contain the log files from each process mkdir /home/iepm/mysql/logs chown iepm:iepm /home/iepm/mysql/logs # The pids from the daemons are stored here mkdir /home/iepm/mysql/pids chown iepm:iepm /home/iepm/mysql/pids # The files in the keepalives directory are used by the monitoring software to ascertain that # the daemons are running mkdir /home/iepm/mysql/keepalives # prime the pump with: touch /home/iepm/mysql/keepalives/traced.alive touch /home/iepm/mysql/keepalives/pingd.alive touch /home/iepm/mysql/keepalives/bw-synched.alive touch /home/iepm/mysql/keepalives/pathchirpd.alive touch /home/iepm/mysql/keepalives/load-datad.alive touch /home/iepm/mysql/keepalives/load-scheduled.alive touch /home/iepm/mysql/keepalives/owpingd.alive # set the permissions so that the iepm account can access them chown -R iepm:iepm /home/iepm/mysql/data chown -R iepm:iepm /home/iepm/mysql/logs chown -R iepm:iepm /home/iepm/mysql/keepalives chown -R iepm:iepm /home/iepm/mysql/pids

• The output from the analysis and reports must go into a directory which is writeable by the 'iepm' account. Generally this is '/home/iepm/public_html'. Make this directory with by using the commands:

  mkdir /home/iepm/public_html mkdir /home/iepm/public_html/<aliasname> chown -R iepm:<account> /home/iepm/public_html

  Where <account> is the account your UNIX id is under. For example, for 'cyrus:iepm' <account> would be replaced by iepm.
• Create a link to this area from /var/www/html as your document root of apache will be /var/www/html.

  ln -s /home/iepm/public_html/<aliasname> /var/www/html/<aliasname>

• IEPM-BW requires a simple configuration file, '/etc/iepm.cnf'. Create the file by the command

  mkdir /etc/iepm.cnf

  Copy the following contents into the file and make the required changes.

  # required iepm configuration parameters # /etc/iepm.conf dataBase = "iepm" dataBaseHost = "<fully qualified monitoring host name>" dataBaseDir = "/home/iepm/mysql" iepmSrcDir = "/home/iepm/v3src" updateAcct = "iepm" acctGroup = "<account group>" readAcct = "readonly" # This is provided as the monitoring host and database host could be # different machines. # It is not advisable for them to be different. In monitoring a network, # one should avoid using the network for the monitoriong control and data # logging. monHost = "<fully qualified monitoring host name>"; aliasName = "<aliasname>"; monHostip = "<monitoring host ip address>"; mysqlport = 3306; #Connie Logg 5/12/04 cal@slac.stanford.edu <- configurator's name and date please

  An example iepm.cnf file is below to help you in changing parameters specific to your site.

  #required iepm configuration parameters # /etc/iepm.conf dataBase = "iepm" dataBaseHost = "iepm-ncp.ncp.edu.pk" dataBaseDir = "/home/iepm/mysql" iepmSrcDir = "/home/iepm/v3src" updateAcct = "iepm" acctGroup = "iepm" readAcct = "readonly" # This is provided as the monitoring host and database host could be different machines # It is not advisable for them to be different. In monitoring a network, one should avoid using the # network for the monitoriong control and data logging. monHost = "iepm-ncp.ncp.edu.pk"; aliasName = "iepm-ncp.ncp.edu.pk"; monHostip = "202.83.167.108"; mysqlport = 3306;
