OpenNMS 是一套 OpenSource 的網路管理軟體，可以利用 Ping 及 SNMP 的方式來偵測網路設備或服務的啟動狀態。

[@more@]
下載 OpenNMS 套件庫 rpm
# wget http://yum.opennms.org/repofiles/opennms-repo-stable-rhel6.noarch.rpm
進行安裝
# rpm -Uvh opennms-repo-stable-rhel6.noarch.rpm
安裝 PostgreSQL 資料庫
# yum install postgresql postgresql-server
PostgreSQL 初始化資料庫
# service postgresql initdb
正在初始化資料庫： [ 確定 ]
啟動 PostgreSQL Server
# service postgresql start
正在啟動 postgresql 服務： [ 確定 ]
如果沒有先初始化資料庫，而直接啟動，則會出現下面的錯誤訊息
# service postgresql start
/var/lib/pgsql/data is missing. Use “service postgresql initdb” to initialize the cluster first.
[失敗]
設定開機時啟動
# chkconfig –level 3 postgresql on
先備份設定檔，再進行修改
# cp /var/lib/pgsql/data/pg_hba.conf /var/lib/pgsql/data/pg_hba.conf.$(date +%F)
將 70 行後的 ident 取代成 trust
# sed -i ’70,$s/ident/trust/’ /var/lib/pgsql/data/pg_hba.conf
重新啟動 PostgreSQL Server
# service postgresql restart
正在停止 postgresql 服務： [ 確定 ]
正在啟動 postgresql 服務： [ 確定 ]
檢查是否有正常啟動 PostgreSQL Server
# netstat -antulp | grep 5432
tcp 0 0 127.0.0.1:5432 0.0.0.0:* LISTEN 8092/postmaster
tcp 0 0 ::1:5432 :::* LISTEN 8092/postmaster
安裝 Oracle Java JDK
Oracle Java JDK 下載網頁：
http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
# rpm -ivh jdk-7u45-linux-x64.rpm
進行 Oracle Java JDK 設定
# alternatives –install /usr/bin/java java /usr/java/jdk1.7.0_45/bin/java 100
# alternatives –set java /usr/java/jdk1.7.0_45/bin/java
# echo ‘export JAVA_HOME=/usr/java/jdk1.7.0_45’ >> /etc/profile
# echo ‘export PATH=$PATH:$JAVA_HOME/bin’ >> /etc/profile
# echo ‘export CLASSPATH=$JAVA_HOME/jre/lib/ext:$JAVA_HOME/lib/tools.jar’ >> /etc/profile
# source /etc/profile
檢查 Java 版本
# java -version
java version “1.7.0_45”
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)
安裝 OpenNMS
# yum -y install opennms opennms-plugins opennms-remote-poller mib2opennms iplike
*** Installation complete. You must still run the installer at
*** $OPENNMS_HOME/bin/install to be sure your database is up
*** to date before you start OpenNMS. See the install guide at
*** http://www.opennms.org/wiki/Installation:RPM and the
*** release notes for details.
設定 OpenNMS 環境變數
# export OPENNMS_HOME=/opt/opennms
# echo ‘export PATH=$PATH:$OPENNMS_HOME/bin’ >> /etc/profile
設定 OpenNMS 使用的 Java
# /opt/opennms/bin/runjava -S /usr/java/latest/bin/java
runjava: checking specified JRE: “/usr/java/latest/bin/java”…
runjava: specified JRE is good.
runjava: value of “/usr/java/latest/bin/java” stored in configuration file
# $OPENNMS_HOME/bin/runjava -s
runjava: Looking for an appropriate JRE…
runjava: Checking for an appropriate JRE in JAVA_HOME…
runjava: found: “/usr/java/jdk1.7.0_45/bin/java” is an appropriate JRE
runjava: value of “/usr/java/jdk1.7.0_45/bin/java” stored in configuration file
建立 OpenNMS 需要的資料庫
# $OPENNMS_HOME/bin/install -dis
最後會出現
Upgrade completed successfully!
啟動 OpenNMS
# service opennms start
Starting OpenNMS: Started OpenNMS, but it has not finished starting up
[失敗]
設定開機時啟動
# chkconfig –level 3 opennms on
雖然最後的訊息出現失敗，但有正常執行
# netstat -antulp | grep 8980
tcp 0 0 :::8980 :::* LISTEN 8956/java
tcp 0 0 :::18980 :::* LISTEN 8956/java
如果不放心，可以檢查 log 檔的訊息
# cat /opt/opennms/logs/daemon/output.log
[DEBUG] System property ‘opennms.library.jicmp’ set to ‘/usr/lib64/libjicmp.so. Attempting to load jicmp library from this location.
[INFO] Successfully loaded jicmp library.
[DEBUG] System property ‘opennms.library.jicmp6’ set to ‘/usr/lib64/libjicmp6.so. Attempting to load jicmp6 library from this location.
[INFO] Successfully loaded jicmp6 library.
