如果是在 centos 7 的環境
一般是從官網下載的 ELK 套件(RPM)
安裝好就能動, 需要改動的設定不多
如果是要套用以前的設定, 如 logstash, 常常會有自訂的設定或引用
記得參考路徑要改正確, 不然會一直起不來, 但又沒法看出設定上的錯誤
——————————————————————————–
另外, GeoIP 在 logsatsh 2.x版是用 GeoIP的 version 1 (dat)
到了 logstash 5.x 版以後, 已支援 GeoIP 的 veresion 2 (mmdb)
也記得要改一下參考路徑, 不過好在其他的設定是不用動的(例如, country_code2, longitude, latitude…)

2.x 常用的 head, kopf 的 es plugins 也要不能用
5.x 有建議使用 cerebro (kopf 的新名稱)

環境
1. 目錄 01-src 為資料來源
2. 目錄 02-dst 為資料備份
3. 目錄 03-bak 為備份過程中, 因備份動作產生的增刪檔案暫存區
情境一
[說明] 當 01-src 裡面有檔案被刪除時, 02-dst 在備份時也跟著要刪除同一檔案時, 會將被刪除的檔案, 利動到 03-bak
[指令]
rsync -av --delete ./01-src/ ./02-dst --backup --backup-dir=../03-bak
[結論] backup-dir 若不特別指定路徑的話, 就會被02-dst這個目錄做為當前目錄, 以我們的範例而言, 就是要用兩個點來退到上一層目錄去

REF: https://askubuntu.com/questions/760952/slow-shutdown-on-ubuntu-16-04-lts-stopping-thermal-daemon-running-fit-make-remo
I have got the same Problem. It occurred after clean install Ubuntu 16.04. Finally I figured out, after lots of troubleshooting, that (after disable the Ubuntu boot splash screen) a certain stop-job was running that made the shutdown slow. (Thanks to Alex!) Then I got this error report:
a stop job is running for make remote cups printers available locally
Then I tried this:
sudo systemctl stop cups-browsed.service
sudo systemctl disable cups-browsed.service
To verify:
sudo systemctl status cups-browsed
sudo systemctl is-enabled cups-browsed
and it finally worked! Shutdown was now as good and fast as ever. (You can find this troubleshooting on: “The Annoying Cups Browsed” at the ec-cwang´s Blog!)
