2、swordnagios（设置密码）2.修改安装文件夹权限chownnagios.nagios/usr/local/nagios一、安装nagios主程序tar-zxvfnagios-3.0.6.tar.gzcdnagios-3.0.6./configure–prefix=/usr/local/nagios–with-command-group=nagiosmakeallmakeinstallmakeinstall-initmakeinstall-configmakeinstall-commandmodels/usr/local/nagios(

3、查看是否有etc、bin、sbin、share、var、libexec这六个目录，如果有，表示安装成功)cd..二、安装nagios-plugins插件1、tar-zxvfnagios-plugins-1.4.9.tar.gzcdnagios-plugins-1.4.9./configure--prefix=/usr/local/nagios--with-nagios-user-nagios--with-nagios-group=nagiosmakemakeinstallls/usr/local/nagios/libexec(会显示很多插件)

4、2、将apache的运行用户加到nagios组里面从httpd.conf中过滤出当前的apache运行用户：grep^User/etc/httpd/conf/httpd.confUserapache（返回值）我的是apache,下面将这个用户加入nagios组usermod-Gnagiosapache3、修改apache配置文件vi/etc/httpd/conf/httpd.confshift+g跳至文件最后，并加入如下内容：#settingfornagios20090325#settingbybbs.linuxtone.orgScriptA

7、l/nagios/etc/htpasswdmchNewpassword:(输入monitorapp)Re-typenewpassword:(再输入一次monitorapp)Addingpasswordforusermch查看访问账号文件的内容：less/usr/local/nagios/etc/htpasswdmch:1fP3yU3wSwRH6前面是用户名mch,后面是加密后的密码ctrl+z退出5、修改cgi.cfg文件编辑cgi.cfg文件，将开始建立的用户名mch添加到里面，允许该账户通过web登陆（如果有多个登陆账号，在后面用,号隔开

8、）。vi/usr/local/nagios/etc/cgi.cfgauthorized_for_system_information=nagiosadmin,mch
