CentOS 7 PXE Server：192.168.131.241
與 頭城國小資訊組 | 使用 PXE Server 來安裝 Ubuntu Server 16.04.2 相同，底下僅列出不一樣的地方
1. 修改設定檔 /var/lib/tftpboot/pxelinux.cfg/default

3. 處理 SELinux
# restorecon -R -F -v /var/ftp/pub/

4. Client 端以 PXE 網路開機

參考網頁：
Ubuntu 16.04 / Debian 8: Run PXE boot server for automated install – Narrow Escape

CentOS 7 PXE Server：192.168.131.241
1. 下載 Ubuntu Server netboot image 網路開機檔
# wget http://archive.ubuntu.com/ubuntu/ubuntu/dists/xenial/main/installer-amd64/current/images/netboot/netboot.tar.gz -O ubuntu-16.04-netboot.tar.gz

2. 建立目錄
# mkdir /var/lib/tftpboot/ubuntu_server
# mkdir ubuntu-16.04-netboot

3. 解壓縮，並移動到 /var/lib/tftpboot/ubuntu_server 目錄下
# tar zxf ubuntu-16.04-netboot.tar.gz -C ubuntu-16.04-netboot
# mv ubuntu-16.04-netboot/ubuntu-installer /var/lib/tftpboot/ubuntu_server[@more@]
4. 修改設定檔 /var/lib/tftpboot/pxelinux.cfg/default
# vim /var/lib/tftpboot/pxelinux.cfg/default
LABEL Ubuntu Server 16.04.2 x64 FTP Install
MENU LABEL Ubuntu Server 16.04.2 FTP Install
kERNEL /netboot/ubuntu_server/ubuntu-installer/amd64/linux
APPEND initrd=/netboot/ubuntu_server/ubuntu-installer/amd64/initrd.gz url=ftp://192.168.131.241/pub/Ubuntu16042/preseed/ubuntu-server.seed

5. 下載 Ubuntu Server 16.04.2 ISO
# wget http://debian.linux.org.tw/ubuntu-releases/16.04.2/ubuntu-16.04.2-server-amd64.iso

6. 掛載光碟
# mount -o loop ubuntu-16.04.2-server-amd64.iso /mnt

7. 複製檔案到 FTP Server
# mkdir /var/ftp/pub/Ubuntu16042
# cp -a /mnt/* /var/ftp/pub/Ubuntu16042

8. 處理 SELinux
# restorecon -R -F -v /var/lib/tftpboot/
# restorecon -R -F -v /var/ftp/pub/

9. Client 端以 PXE 網路開機

本來一直以為 Debian/Ubuntu 只能透過 LiveCD 來進行客製化，偶然在以下的網站發現 Debian/Ubuntu 也能像 RedHat/CentOS 的 kickstart 一樣，透然編輯文字檔的方式來達成自動安裝的工作。

7. 進行安裝測試
選擇安裝語言


選擇 Auto Install Ubuntu Server

不知道為什麼，要重新再選擇一次 locales

設定 root 密碼

分割硬碟

設定 MySQL Server 管理者密碼

安裝完成，重新啟動

參考網站：
Debian / Ubuntu 安裝 Let’s Encrypt 到 Apache – Linux 技術手札

1. 安裝 Apache Web Server
# apt-get install apache2

2. 啟用 SSL 模組並重新啟動 Apache Web Server
# a2enmod ssl
Considering dependency setenvif for ssl:
Module setenvif already enabled
Considering dependency mime for ssl:
Module mime already enabled
Considering dependency socache_shmcb for ssl:
Enabling module socache_shmcb.
Enabling module ssl.
See /usr/share/doc/apache2/README.Debian.gz on how to configure SSL and create self-signed certificates.
To activate the new configuration, you need to run:
  service apache2 restart

# a2ensite default-ssl.conf
Enabling site default-ssl.
To activate the new configuration, you need to run:
  service apache2 reload

# /etc/init.d/apache2 restart
or
# systemctl restart apache2.service[@more@]3. 安裝 git 套件
# apt-get install git

4. 下載 Let’s Encrypt 的目錄
# cd /usr/local
# git clone https://github.com/letsencrypt/letsencrypt
Cloning into ‘letsencrypt’…

IMPORTANT NOTES:
 – If you lose your account credentials, you can recover through
   e-mails sent to t850008@gmail.com.
 – The following errors were reported by the server:

   Domain: www.test.ilc.edu.tw
   Type:   connection
   Detail: Failed to connect to 192.168.1.1:443 for TLS-SNI-01
   challenge

   To fix these errors, please make sure that your domain name was
   entered correctly and the DNS A record(s) for that domain
   contain(s) the right IP address. Additionally, please check that
   your computer has a publicly routable IP address and that no
   firewalls are preventing the server from communicating with the
   client. If you’re using the webroot plugin, you should also verify
   that you are serving files from the webroot path you provided.
 – Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.

在安裝 Ubuntu Server 16.04.2 出現 無法安裝 busybox-initramfs 的訊息

[@more@]主要的原因是我在使用光碟開機安裝時，選用了中文(繁體)

改用 English 就沒有問題了！

在 Cacti 管理畫面 Console / System Utilities / Technical Support 畫面中，出現的警告訊息：
ERROR: Installed RRDTool version does not match configured version.
Please visit the Configuration Settings and select the correct RRDTool Utility Version.

檢查系統安裝的 RRD Tool 版本，是 1.5.5-4
# dpkg -l | grep rrd
ii  librrd4:amd64                      1.5.5-4                            amd64        time-series data storage and display system (runtime library)
ii  rrdtool                            1.5.5-4                            amd64        time-series data storage and display system (programs)

可是在 Console / Settings / General 頁面中，RRDTool Utility Version 只有 1.0~1.4 版可以選擇

[@more@]解決方式：
參考 Cacti + RRDtool 錯誤訊息 @mini box 迷你盒子 – nidBox親子盒子

參考網頁：
OpenNMS Installation Guide
雜亂的學習筆記本: OpenNMS – OpenNMS 安裝篇(04) – Cassandra 的安裝與 Newts 的設定

根據官方網站上的解釋：
Newts 是基於 Apache Cassandra 的時間序列資料儲存，是一個持久性的策略，可以用來取代 JRobin 或是 RRDtool。

在 Ubuntu 16.04 下安裝
1. 新增 DataStax 套件庫設定檔
# vim /etc/apt/sources.list.d/cassandra.sources.list
deb https://debian.datastax.com/community stable main

2. 安裝 GPG Key
# wget -O – https://debian.datastax.com/debian/repo_key | apt-key add –

3. 更新套件庫
# apt-get update[@more@]
4. 安裝 Cassandra 3.0.x package
# apt-get install dsc30
如果出現下面的錯誤訊息，請下載 python-support 進行安裝
The following packages have unmet dependencies:

5. 設定 OpenNMS Horizon
# cp /usr/share/opennms/etc/opennms.properties /usr/share/opennms/etc/opennms.properties.$(date +%F)
將 false 改為 true
# sed -i ‘/rrd.storeByForeignSource/s/false/true/’ /usr/share/opennms/etc/opennms.properties
取消前面的註解，並將 rrd 改為 newts
# sed -i ‘/^#org.opennms.timeseries/s/#org.opennms.timeseries.strategy=rrd/org.opennms.timeseries.strategy=newts/’ /usr/share/opennms/etc/opennms.properties
取消前面的註解
# sed -i ‘/newts.config.hostname/s/^#org/org/’ /usr/share/opennms/etc/opennms.properties
# sed -i ‘/keyspace/s/^#org/org/’ /usr/share/opennms/etc/opennms.properties
# sed -i ‘/9042/s/^#org/org/’ /usr/share/opennms/etc/opennms.properties

6. 初始化 newts
# /usr/share/opennms/bin/newts init

7. 進行驗證
# cqlsh

8.重新啟動 OpenNMS
# systemctl restart opennms
