3. Simple Steps for establishing the distributed Nagios + ndoutils + MySQL environment (provided that the independent environments work normally)V) set a centrally managed database to allow Nagios users to log on to and operate the database from other hosts. W) modify the ndo2db configuration files respectively. CFG: db_host, db_name, db_user, db_passx) modify the ndomod configuration files respectively. CFG field: instance_namey) Restart ndo2dbz) Restart nagiosaa) test whether data in MySQL has been distinguished by different instances. If yes, OK
