這段時(shí)間在2臺(tái)虛擬機(jī)上分別通過(guò)CentOS5.8和RHEL6.0安裝nagios的客戶端,CentOS一切順利。但是,RHEL不斷給我制造麻煩。前幾天在RHEL環(huán)境yum安裝mysql遇到問(wèn)題,耽誤2天時(shí)間。昨晚又因?yàn)樵赗HEL上安裝dos2unix命令,昨晚加上今天下午又折騰1個(gè)小時(shí)。
今天凌晨通過(guò)下載軟件包,編譯安裝始終報(bào)錯(cuò)。今天下午在百度搜索yum安裝這個(gè)命令,也不怎么得要領(lǐng)。于是又嘗試直接通過(guò)yum指定“dos2unix*”(執(zhí)行“yum -y install dos2unix*”命令),沒(méi)想到,竟然安裝成功,后面的測(cè)試也沒(méi)有問(wèn)題。
昨晚折騰到0:40,實(shí)在不想睡得太晚。雖然有些不甘心,但還是收拾收拾準(zhǔn)備就寢。那時(shí)候,就又開(kāi)始猶豫:到底要不要堅(jiān)持繼續(xù)在RHEL上安裝nagios客戶端。即使次日把dos2unix命令成功安裝,后面可能還會(huì)遇到其它問(wèn)題。但是,轉(zhuǎn)念再想:發(fā)現(xiàn)問(wèn)題,解決問(wèn)題的過(guò)程,正是自己提高的過(guò)程。畢竟,工作基本落實(shí),不再為生計(jì)擔(dān)心。再花些時(shí)間解決這類小問(wèn)題,應(yīng)該也沒(méi)什么大不了的。
況且,linux本身就是各類小知識(shí)的繁雜集合。如果小問(wèn)題都不能處理,大問(wèn)題遇到的時(shí)候,更抓瞎。
為什么RHEL6沒(méi)有dos2unix這個(gè)命令呢?是我當(dāng)初在安裝系統(tǒng)的時(shí)候沒(méi)有選擇好軟件包的原因嗎?天知道……
----------------------------------------開(kāi)始說(shuō)正事----------------------------------------------
[root@nagios_client02 nagios]# dos2unix /usr/local/nagios/libexec/check_memory.pl

[root@nagios_client02 nagios]# dos2unix /usr/local/nagios/libexec/check_iostat
-bash: dos2unix: command not found
[root@nagios_client02 nagios]# cd ..
執(zhí)行dos2unix命令,提示命令沒(méi)有找到。可能是dos2unix在RHEL環(huán)境沒(méi)有安裝。
在百度搜索安裝dos2unix命令,根據(jù)文檔:“http://blog.csdn.net/bluewhale1/article/details/8074978——dos2unix命令找不到怎么辦”操作。
