  1. Decide what accounts are going to be needed. Assume the account 'cal' 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>, 'slac'. For this example, I will assume that the home directory for the 'cal' account is '/home/cal', and the home directory for the 'iepm' account is '/home/iepm'. For the sake of consistency beteween monitoring systems, the account 'iepm' with '/home/iepm' is strongly recommended.
  2. The monitoring host has a name. This is referred to as '<fully qualified monitoring host name>'.
  3. 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.caltech.ul-org
    • iepm-bw.cern.ch
    • iepm-bw.bnl.org
    • iepm-bw.snv.ul-org
    • iepm-bw.fzk.de
  4. If the account mysql:mysql has not been allocated, allocate it by:
    Code Block
    groupadd -g 20000 mysql
    useradd -u 20000 -g mysql mysql
    
  5. Decide on the directory structure for the mysql data base and the monitoring code. It is best to have the mysql data base on a separate physical disk from the system disk, but if this is not possible, use '/home/iepm/mysql' as the base. Make the mysql directory.
    Code Block
    mkdir /home/iepm/mysql
    chown mysql:mysql /home/iepm/mysql
    
  6. Create a configuration file for /etc/my.cnf which MySQL will use when you install the database.
    Code Block
    [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
    
  7. If mysql is already running, it is running with the 'test' database. Kill the mysql daemons.
  8. Restart MySQL with 'mysqld_safe&'. This will restart the MySQL server with the configuration file /etc/my.cnf.
  9. Create the data base by executing 'mysql_install_db'.
  10. Change the ownership of '/home/iepm/mysql' by the command chown 'chown -R mysql:mysql /home/iepm/mysql'.
  11. Set the database root password with 'mysqladmin -u root password "new password" '.
  12. 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:slac' replaced with 'slac' replaced by the appropirate group for the 'iepm' account.
    Code Block
    # 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.
    mkdir /home/iepm/mysql/data
    chown iepm:slac /home/iepm/mysql/data
    # the logs directory contain the log files from each process
    mkdir /home/iepm/mysql/logs
    chown iepm:slac /home/iepm/mysql/logs
    # the pids from the daemons are stored here
    mkdir /home/iepm/mysql/pids
    chown iepm:slac /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:slac /home/iepm/mysql/data
    chown \-R iepm:slac /home/iepm/mysql/logs
    chown \-R iepm:slac /home/iepm/mysql/keepalives
    chown \-R iepm:slac /home/iepm/mysql/pids
    
  13. 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:
    Code Block
    mkdir /home/iepm/public_html
    mkdir /home/iepm/public_html/<aliasname>
    chown -R iepm:<account> /home/iepm/public_html
    
  14. Create a link to this area from /var/www/html
    Code Block
    ln -s /home/iepm/public_html/<aliasname> /var/www/html/<aliasname>
    
  15. IEPM-BW requires a simple configuration file, '/etc/iepm.cnf'. The contents of /etc/iepm.cnf should contain:
    Code Block
    # 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;
