聽說一般人對 壹網樂、網樂通、網通樂、通樂網…還是不一定搞得清。 改機在不同時期有不同的改法，現在方便很多了。 以前要會接 TTL-to-COM or TTL-to-USB console 。現在只需照教學步驟就可以改出基本環境來用。 （運氣好的話）一般會卡住的步驟，則需 Linux 相關知識來做判斷解決。幾乎要慘到硬體或 DOM 出問題才需要接 console 看問題出在哪。 把安裝的記錄下來。 一系列的記錄會是使用 sh4twbox 灌 NexNAS-wheezy-sh4twbox092 參考資訊：各取了自己要用到的部份…所以還是再自己整理一份筆記  派樂靈丹 - TWPDA http://www.twpda.com/2013/09/sh4twbox-07.html  橘子老師教學資料庫 http://

參考 http://nagios.sourceforge.net/docs/nrpe/NRPE.pdf http://www.debianhelp.co.uk/nagiospluins.htm 比較： nagios server端：192.168.1.2 ，已在web server根目錄放 index.html 的 nagios server端 client 端：192.168.1.133，web server根目錄沒東西，check_http 正常會回應 403 Forbidden 兩者在 nrpe.cfg 都沒定義  check_http ，但 command-plugins.cfg 有command[check_http] nagios server端： nagiosserver~]# /usr/lib64/nagios/plugins/check_http -H

*被監視端： 從剛裝好完全沒東西的 VM開始… CentOS5.5 用 rpmforge 的來源做 yum 安裝，plugins 是放在 /usr/lib64/nagios/plugins/ yum install nrpe 會安裝 fping nagios-plugins perl-Crypt-DES perl-Net-SNMP /etc/nagios/ 裡只會出現 command-plugins.cfg  nrpe.cfg 兩個檔 /usr/lib64/nagios/plugins/ 會有其它 check項目 修改 /etc/nagios/nrpe.cfg  註解掉 #server_address= allow_hosts= service nrpe restart 之後 *檢查 netstat -at | grep 5666

server 裝好的 localhost CentOS5.5 用 rpmforge 的來源做 yum 安裝，plugins 是放在 /usr/lib64/nagios/plugins/ ...首先 /etc/nagios/nrpe.cfg 裡的 server_address= allow_hosts= 後面跟的 IP 不能用逗點加別的 ip (例如：192.168.2.3,127.0.0.1) 目前先試只定義 server_address 1個 IP allow_hosts 註解掉 iptables 加上   -p tcp -m tcp --dport 5666 -j ACCEPT service nrpe restart 之後 /usr/lib64/nagios/plugins/check_nrpe -H {host}

想新增一項目來看Linux client端的記憶體使用情形（Windows的預設有此項目） 預設沒有此command可處理… 記錄改了多少東東… 實作完…問題在佈署 Client 端(安裝 nagios-nrpe ，nagios-nrpe-plugins) *在 /usr/lib64/nagios/plugins/  新增command用的shell script， 記得chmod 755（權限要跟其它plugin一樣） 實作時用的是下列討論區用的 script： http://serverfault.com/questions/195815/nagios-memory-configuration 另有一版本可參考 http://www.linuxquestions.org/questions/linux-software-2/

起因：看到 check_nt 可以看 Windows Client 的 memory usage ...Linux預設沒有... 由於預設沒有此command可處理，所以開始… 小記：實作記錄見下篇 *在 /usr/lib64/nagios/plugins/  新增command用的shell script， 記得chmod 755（權限要跟其它plugin一樣） *在 /etc/nagios/objects/commands.cfg 新增 command *在 /etc/nagios/nrpe.cfg 新增 command *在 /etc/nagios/objects/對象設定檔.cfg 新增 service 先貼大致用上的 link 做一個 .sh 檔來 check memory ========================================

＊ Windows Client 要安裝的 NSClient++ 新版的 client 會自動加規則到內建的防火牆 但這次遇到 nagios server端的 objects/commands.cfg，  預設 $HOSTADDRESS& -p 這段後面不是 IP，會有"server port is not interger" 之類的訊息 就算 NSClient 的設定檔不刻意設定 port ，也要在 commands.cfg 裡指定“ -p 12489” NSClient++ 安裝時（或事後更改設定檔）設定的密碼 為明碼，在 nagios server端的 objects/commands.cfg  找到(預設應該完全沒有?)  command_line    $

http://blog.xuite.net/jyoutw/xtech/46682931 在所有的網頁中，找出含有某特定字串的檔案。 例如說要找出含有 localhost 字串的檔案，記得 grep 沒有 recursive 的參數，可以搜尋包含子目錄 所以就要利用 find 的功能來協助 # find ./ -type f -name \*.php |xargs grep 'localhost' 用上面的方式連是哪個檔案都會列出來，若用下列的寫法，速度既慢而且也無法得知是哪個檔案有含該字串： # find ./ -type f -name \*.php -exec grep 'localhost' {} \;

在分析 apache log 時最常用的就是 IP 排序+統計，如果三不五時都要把 webalizer 叫出來跑，實在是有點辛苦，所以我們家 J神 就提供了一個簡易的語法，非常精準好用。 cat access.log |awk ‘{print $1}’|sort|uniq -c|sort -rn|head -n 10 這樣子會排出前十名 hit 最高的 IP，結果就會像 2416 123.156.xx.212 601 122.122.xx.101 583 114.38.xx.214 565 218.168.xx.140 526 114.43.xx.250 525 114.41.xx.40 476 218.168.xx.72 449 115.43.xx.154 424 114.42.xx.172 389 218.169.xx.162
