nagios监控windows及linux从而实现飞信报警

nagios主要功能是实现报警yum环境搭建:[root@localhost~]#mount/dev/cdrom/mnt/cdrom/mount:blockdevice/dev/cdromiswrite-protected,mountingread-only[root@localhost~]#vim/etc/yum.repos.d/rhel-debuginfo.repo[rhel-server]name=RedHatEnterpriseLinuxserverbaseurl=file:///mnt/cdrom/Serverenabled=1gpgcheck=1gpgkey=file:///mnt/cdrom/RPM-GPG-KEY-redhat-release安装步骤安装lamp环境yuminstallmysqlmysql-develhttpdphpphp-gdphp-mbstring测试lamp环境创建一个组nagcmd[root@localhostnagios-3.2.1]#groupaddnagcmd创建一个账号nagios[root@localhostnagios-3.2.1]#useradd-mnagios加入组[root@localhostnagios-3.2.1]#usermod-a-Gnagcmdnagios将apache账号也添加进来[root@localhostnagios-3.2.1]#usermod-a-Gnagcmdapache解压缩cdnagios-cn-3.2.3配置./configure--with-command-group=nagcmd--enable-event-broker或者./configure--with-command-group=nagcmd--prefix=/usr/local/nagios--sysconfdir=/etc/nagios--enable-event-brokerroot@localhostnagios-3.2.1]#makeall[root@localhostnagios-3.2.1]#makeinstall（-Thisinstallstheinitscriptin/etc/rc.d/init.d）makeinstall-commandmode-Thisinstallsandconfigurespermissionsonthedirectoryforholdingtheexternalcommandfilemakeinstall-config-Thisinstallssampleconfigfilesin/usr/local/nagios/etc进入nagios目录cd/usr/local/nagios/在http服务器的配置目录（conf.d）下形成nagiosweb程序cdnagios-cn-3.2.3makeinstall-webconf创建一个登陆nagiosweb程序的用户这个账号在以后通过web登陆nagios认证时使用htpasswd-c/usr/local/nagios/etc/htpasswd.usersnagiosadmin启动apacheservicehttpdstartchkconfighttpdon安装nagios插件./configure（perfix=/usr/local/nagios）--with-nagios-user=nagios--with-nagios-group=nagios或者./configure--with-nagios-user=nagios--with-nagios-group=nagiosmakemakeinstall将nagios服务加入chkconfig管理之类chkconfig--addnagioschkconfig--addnagios检查nagios的配置文件的语法是否正确/usr/local/nagios/bin/nagios-v/usr/local/nagios/etc/nagios.cfg可以将/usr/local/nagios/bin加入命令搜索路径中vim.bashrc..bashrc重新读取环境文件可以将/usr/local/nagios/etc/nagios.cfg设置为一个连接ln-s/usr/local/nagios/etc/nagios.cfg/etc/nagios.cfg检查语法nagios-v/etc/nagios.cfg启动nagios服务启动httpd服务编辑vim/usr/local/nagios/etc/nagios.cfg注释36行#cfg_file=/usr/local/nagios/etc/objects/localhost.cfg重启nagios会报错，原因，是无可监控打开该文件中的其他主机比如windows39cfg_file=/usr/local/nagios/etc/objects/windows.cfg重启服务windows检测客户端配置Snmp161Nsclienrt12489check_ntNrpe5666naclient改变里面的ns.ini然后从其windows上的ncclient在nagios服务器上，更改object下的window。dfg定义重启nagios服务
