利用時間完成，採手動的方式來進行後續的設定工作
在 /root 目錄下放置 README 檔案，說明設定的步驟！
# cat /root/README
# 底下請以 root 身份執行
# Java 設定
# /opt/opennms/bin/runjava -s
#
# PostgreSQL Server初始化資料庫
# /usr/bin/postgresql-setup initdb
# sed -i ‘/^host/s/…..$/md5/’ /var/lib/pgsql/data/pg_hba.conf[@more@]#
# 重新啟動 PostgreSQL Server
# systemctl enable postgresql.service
# systemctl restart postgresql.service
#
# PostgreSQL Server 資料庫設定帳號及密碼
# sudo -u postgres psql -c “CREATE USER opennms WITH PASSWORD ‘密碼’;”
# sudo -u postgres psql -c “CREATE DATABASE opennms;”
# sudo -u postgres psql -c “GRANT ALL PRIVILEGES ON DATABASE opennms to opennms;”
#
# OpenNMS 資料庫帳號及密碼設定
# sed -i -e ‘s/password=”opennms”/password=”密碼”/’ -e ‘s/password=””/password=”密碼”/’ -e ‘s/user-name=”postgres”/user-name=”opennms”/’ /opt/opennms/etc/opennms-datasources.xml
#
# 初始化 OpenNMS
# /opt/opennms/bin/install -dis
#
# RRD 設定
# sed -i ‘/MultithreadedJniRrdStrategy/s/^#org/org/’ /opt/opennms/etc/rrd-configuration.properties
# sed -i ‘/rrd2/s/^#opennms/opennms/’ /opt/opennms/etc/rrd-configuration.properties
# sed -i ‘/rrd2/s/^#org/org/’ /opt/opennms/etc/rrd-configuration.properties
#
# OpenNMS 啟動並設定開機時啟動
# systemctl enable opennms.service
# systemctl start opennms.service
執行紅字部分的指令
如果碰到 SELinux 的問題，可以先試著關掉！
# sed -i ‘s/^(SELINUX=).*$/1”disabled/’ /etc/selinux/config
# sync;sync;sync;reboot
如果要取消 OpenNMS 自動更新
# sed -i ‘/gpgcheck/aenable=0’ /etc/yum.repos.d/opennms-repo-stable-rhel7.repo
反之
# sed -i ‘s/enable=0/enable=1/’ /etc/yum.repos.d/opennms-repo-stable-rhel7.repo
