【移動(dòng)應(yīng)用開發(fā)技術(shù)】Nagios的搭建

前些天搭建了一個(gè)Cacti上線后運(yùn)行的不錯(cuò)監(jiān)控服務(wù)器的實(shí)時(shí)運(yùn)行狀態(tài)也配置了報(bào)警郵件接收等功能后，心情大好。去論壇里溜達(dá)一圈后好多人都說Nagios不錯(cuò)功能上比Cacti還要強(qiáng)上不少呢，于似乎就開始了Nagios研究?；巳斓臅r(shí)候研究Nagios的架構(gòu)。今天開始著手開動(dòng)了;1、首先Nagios搭建的準(zhǔn)備工作很多，LAMP架構(gòu)得搭建吧；2、LAMP搭建之前記得把SElinux與Iptables關(guān)了啊，不要在后面給自己創(chuàng)造麻煩；一、搭建LAMP環(huán)境；(1)、所需要安裝依賴包我在這里就Yum了，沒有rpm一個(gè)一個(gè)的安裝原因你懂得，在這里我搭建的系統(tǒng)環(huán)境是CentOS-5.9-x86_64；我一直喜歡用CentoS那是因?yàn)橐蕾嚢膯栴}好解決啊。RedHat要也想像CentoS那樣方便解決依賴包的問題的話得先把本地的rpm包與第三方的依賴包整合到一起然后在統(tǒng)一搭建Yum源庫的，好了費(fèi)話不說了要不然該挨噴了。[root@Nagios~]#yum-yinstallperlgdgd-devellibpnglibpng-devellibjpeglibjpeg-develzlibzlib-develpcre-develgccgcc-c++makecmakeautoconfopensslopenssl-develncurses-develpatchlibxml2libxml2-develcurl-developenldapopenldap-devellibeventlibevent-develbisoniculibicu-devellibtoolreadline-develnet-snmp-develbzip2-develfreetype-develvim(2)、apache安裝；安裝http[root@Nagios~]#tar-zxfhttpd-2.2.22.tar.gz[root@Nagios~]#cdhttpd-2.2.22[root@Nagioshttpd-2.2.22]#./configure--prefix=/usr/local/apache--enable-so--enable-sl--enable-cgi--enable-rewrite--with-zlib--with-pcre[root@Nagioshttpd-2.2.22]#make&&makeinstallApache安裝完成了下面我來起動(dòng)一下;[root@Nagioshttpd-2.2.22]#/usr/local/apache/bin/apachectlstart起動(dòng)了要是不放心的話在看看apache是否在動(dòng)行；[root@Nagioshttpd-2.2.22]#psaux|grephttpd
