nagios简单安装配置

----------Server端安装设置----------1.安装前的依赖检查,否则yum安装相应的组件###[root@UnixHot ~]# rpm -q httpd php gcc glibc glibc-common gd gd-devel2.创建nagios账户和组[root@UnixHot src]# useradd -m nagios[root@UnixHot src]#groupadd nagcmd[root@UnixHot src]# usermod -a -G nagcmd nagios[root@UnixHot src]#usermod -a -G nagcmd apache3.编译及安装(该处用到上步创建的助记词和组)###[root@UnixHot src]# tar xvf nagios-3.2.0.tar.gz[root@UnixHot src]# cd nagios-3.2.0[root@UnixHot nagios-3.2.0]# less Makefile[root@UnixHot nagios-3.2.0]# ./configure --with-command-group=nagcmd --with-nagios-user=nagios --with-nagios-group=nagios[root@UnixHot nagios-3.2.0]# make all[root@UnixHot nagios-3.2.0]# make install[root@UnixHot nagios-3.2.0]# make install-init （生成init启动脚本）[root@UnixHot nagios-3.2.0]# make install-config （生成一些模板配置文件）[root@UnixHot nagios-3.2.0]# make install-commandmode （设置相应的权限）[root@UnixHot nagios-3.2.0]# make install-webconf （生成Apache配置文件nagios.conf）4.为Nagios设置Web验证的密码。

(注意第一次添加用户用-c选项，以后再添加千万别在用这个选项了，会覆盖以前的所有用户的，这点之时在《RHCE考前冲刺》我已经讲过了。

)[root@UnixHot nagios-3.2.0]# htpasswd -c /usr/local/nagios/etc/ers nagiosadmin5.设置Nagios的开机启动###[root@UnixHot ~]# chkconfig --add nagios[root@UnixHot ~]# chkconfig nagios on6.修改SELinuxchcon -R -t httpd_sys_content_t /usr/local/nagios/sbin/chcon -R -t httpd_sys_content_t /usr/local/nagios/share/7.安装Nagios的插件nagios-plugin 插件是Nagios扩展功能的强大武器，一般好的软件，都支持插件扩展，你可以根据实际的应用，自己开发插件。

[root@UnixHot src]# tar xvf nagios-plugins-1.4.13.tar.gz[root@UnixHot src]# cd nagios-plugins-1.4.13[root@UnixHot nagios-plugins-1.4.13]# ./configure --prefix=/usr/local/nagios--with-nagios-user=nagios --with-nagios-group=nagios[root@UnixHot nagios-plugins-1.4.13]# make && make install8.1配置检测主机是否存活 ###配置文件概述如果安装上面的步骤，安装完成后，配置文件在安装时放在了/usr/local/nagios/etc/目录下[root@UnixHot ~]# cd /usr/local/nagios/etc8.2主配置文件nagios.cfg的配置。

主配置文件的内容很多，对于这个版本，我们需要修改和添加的主要是对象配置文件###即：cfg_file=<file_name>cfg_file=/usr/local/nagios/etc/objects/commands.cfg （命令定义文件）cfg_file=/usr/local/nagios/etc/objects/contacts.cfg （联系人信息定义文件）cfg_file=/usr/local/nagios/etc/objects/contactgroups.cfg （添加此行联系人组定义文件）cfg_file=/usr/local/nagios/etc/objects/hosts.cfg （添加此行主机定义文件）cfg_file=/usr/local/nagios/etc/objects/hostgroups.cfg （添加此行主机组定义文件）cfg_file=/usr/local/nagios/etc/objects/services.cfg （添加此行服务定义文件）cfg_file=/usr/local/nagios/etc/objects/timeperiods.cfg （时间周期定义文件）cfg_file=/usr/local/nagios/etc/objects/templates.cfg# Definitions for monitoring the local (Linux) host#cfg_file=/usr/local/nagios/etc/objects/localhost.cfg （注释掉此行）8.3主机定义文件的配置,在后面追加不同主机，更改主机名及IP即可###[root@UnixHot etc]# vi objects/hosts.cfgdefine host{host_name Nagios-Serveralias Nagios Serveraddress 192.168.0.206check_command check-host-alivecheck_interval 5retry_interval 1max_check_attempts 5check_period 24x7process_perf_data 0retain_nonstatus_information 0contact_groups sagroupnotification_interval 30notification_period 24x7notification_options d,u,r}8.4主机组定义文件的配置,把上步设定的主机加到最后一行,这里现在有四台###[root@UnixHot etc]# vi objects/hostgroups.cfgdefine hostgroup {hostgroup_name System-Adminalias system Admin membersNagios-Server,Oracle-Server,Java-Server,MySQL-Server}8.5服务定义文件的配置(注意:一台Linux主机配有四个选项,其他的网络设备如交换机等高定第一个即可)###define service {host_name Nagios-Serverservice_description check-host-alivecheck_period 24x7max_check_attempts 4normal_check_interval 3retry_check_interval 2contact_groups sagroupnotification_interval 10notification_period 24x7notification_options w,u,c,rcheck_command check-host-alive}define service {host_name Nagios-Serverservice_description check-userscheck_period 24x7max_check_attempts 4normal_check_interval 3retry_check_interval 2contact_groups sagroupnotification_interval 10notification_period 24x7notification_options w,u,c,rcheck_command check_nrpe!check_users}define service {host_name Nagios-Serverservice_description check-loadcheck_period 24x7max_check_attempts 4normal_check_interval 3retry_check_interval 2contact_groups sagroupnotification_interval 10notification_period 24x7notification_options w,u,c,rcheck_command check_nrpe!check_load}define service {host_name Nagios-Serverservice_description check-total-procscheck_period 24x7max_check_attempts 4normal_check_interval 3retry_check_interval 2contact_groups sagroupnotification_interval 10notification_period 24x7notification_options w,u,c,rcheck_command check_nrpe!check_total_procs}###以下的三个服务是针对windows系统的###define service {host_name Web-Serverservice_descriptionCheck-Memory check_period 24x7max_check_attempts 4normal_check_interval 3retry_check_interval 2contact_groups sagroupnotification_interval 10notification_period 24x7notification_options w,u,c,rcheck_command check_nt!MEMUSE!-w 80 -c 90}define service {host_name Web-Serverservice_descriptionCheck-Disk-Ccheck_period 24x7max_check_attempts 4normal_check_interval 3retry_check_interval 2contact_groups sagroupnotification_interval 10notification_period 24x7notification_options w,u,c,rcheck_command check_nt!USEDDISKSPACE!-l c -w 80 -c 90}define service {host_name Web-Serverservice_description Check-Disk-Dcheck_period 24x7max_check_attempts 4normal_check_interval 3retry_check_interval 2contact_groups sagroupnotification_interval 10notification_period 24x7notification_options w,u,c,rcheck_command check_nt!USEDDISKSPACE!-l d -w 80 -c 90}8.6联系人定义文件的配置###[root@UnixHot etc]# vi objects/contact.cfgdefine contact{contact_name nagiosadminuse generic-contactalias Nagios Adminservice_notification_period 24x7host_notification_period 24x7service_notification_options w,u,c,rhost_notification_options d,u,rservice_notification_commandsnotify-service-by-email 这个命令在command.cfg中定义host_notification_commands notify-host-by-email 这个命令在command.cfg中定义email 13717514****@}8.7联系组定义文件配置###[root@UnixHot etc]# vi objects/contactgroups.cfgdefine contactgroup {contactgroup_name sagroupalias system administratorgroup members nagiosadmin}8.8修改目录的所有者###[root@UnixHot etc]# chown -R nagios:nagios objects/8.9检测配置文件是否正确[root@UnixHot etc]# /usr/local/nagios/bin/nagios -v/usr/local/nagios/etc/nagios.cfgTotal Warnings: 0 Total Errors: 0 如果都是0说明配置成功了，如果有错误，好好检查一下。
