实验平台:LInux-5.8,yum源已配置好,SeLinux处于关闭状态
- # yum -y install httpd gcc glibc glibc-common gd gd-devel \
- php php-mysql mysql mysql-devel mysql-server
- # groupadd nagcmd
- # useradd -G nagcmd nagios
- # passwd nagios
- # usermod -a -G nagcmd apache
- # tar zxf nagios-3.3.1.tar.gz
- # cd nagios
- # ./configure --with-command-group=nagcmd --enable-event-broker
- ##--sysconfdir=/etc/nagios 自己可以指定nagios的配置文件路径
- ##--with-command-group=nagcmd 使用前面创建的组
- ##--enable-event-broker 为使用NDOutils做准备的
- # make all
- # make install ##安装nagios
- # make install-init ##安装nagios的init脚本,即/etc/rc.d/init.d/nagios
- # make install-commandmode ##安装命令模式
- # make install-config ##安装生成配置文件
- # make install-webconf ##安装web接口的,识别nagios程序位置/usr/local/nagios/share
- ##然后进入/etc/httpd/conf.d,会发现多了nagios.conf文件,为访问
- ##nagios的web页面定义了一个别名,当访问172.16.14.15/nagios时就可
- ##以访问/usr/local/nagios/share的文件了
- # htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
- # service httpd restart
- # tar zxf nagios-plugins-1.4.15.tar.gz
- # cd nagios-plugins-1.4.15
- # ./configure --with-nagios-user=nagios --with-nagios-group=nagios
- # make
- # make install
- (1)把nagios添加为系统服务并将之加入到自动启动服务队列:
- # chkconfig --add nagios
- # chkconfig nagios on
- (2)检查其主配置文件的语法是否正确:
- # /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
- (3)如果上面的语法检查没有问题,接下来就可以正式启动nagios服务了:
- # service nagios start
- current Load:CPU的负载情况,当前显示是Ok的
- Current Users:用户数
- HTTP:显示HTTP服务事物信息的,当前显示WARNING是因为没有提供web页面
- PING:用来ping主机的
- Root Partition:显示根分区信息的
- SSH:显示SSH的状态的
- Swap Usage:显示交换分区使用情况的
- Total Processes:总进程数状态
- 在右上角还有一个各项状态汇总图
- 安装开发包组:
- yum -y groupinstall "Development Libraries" "Development Tools"
- # useradd -s /sbin/nologin nagios
- # tar zxf nagios-plugins-1.4.15.tar.gz

- group=nagios
- # make all
- # make install
- # tar -zxvf nrpe-2.13.tar.gz
- # cd nrpe-2.13.tar.gz
- # ./configure --with-nrpe-user=nagios \ ##添加nrpe用户
- --with-nrpe-group=nagios \ ##nrpe组
- --with-nagios-user=nagios \ ##nagios用户名
- --with-nagios-group=nagios \ ##nagios组名
- --enable-command-args \ ##向命令传递参数的
- --enable-ssl ##默认选项,监控端和被监控端传递信息需要ssl加密
- # make all
- # make install-plugin ##安装插件
- # make install-daemon ##将nrpe安装成守护进程
- # make install-daemon-config ##安装守护进程的配置文件
- # vim /usr/local/nagios/etc/nrpe.conf
- log_facility=daemon ##日志文件的设施
- pid_file=/var/run/nrpe.pid ##pid文件路径,自己可以定义
- server_address=172.16.14.14 ##监听的地址
- server_port=5666 ##端口号
- nrpe_user=nagios ##nrpe用户
- nrpe_group=nagios ##nrpe组名
- allowed_hosts=172.16.14.15 ##定义本机所允许的监控端的IP地址。
- command_timeout=60 ##定义命令的超时时间
