systemctl restart nagios ============================================================================================= nagios server －－－－》 nagios client 10.1.1.2 10.1.1.3 我们把监控的服务分为公共和私有 公共(public)：如ssh,http,ftp,mysql等。监控本地或远程的公共服务，都可以直接配置 私有(private)：如load,users,disk usage等。监控本地私有服务直接配置就好，监控远程私有服务，需要服务和被监控端安装nrpe 例：监控远程服务器的普通服务（公共服务）。如ssh,http,ftp，mysql等 如：我的被监控端IP为10.1.1.3 1.在nagios服务器的主配置文件里加上10.1.1.3的主机配置文件 # vim /etc/nagios/nagios.cfg cfg_file=/etc/nagios/objects/10.1.1.3.cfg 2，创建这个10.1.1.3.cfg # vim /etc/nagios/objects/10.1.1.3.cfg define host{ use linux-server host_name 10.1.1.3 --主机名，最好/etc/hosts里对应好IP，我这里没有做，就直接写IP alias 10.1.1.3 --显示到web上的名字 address 10.1.1.3 --实际被监控主机IP } define hostgroup{ hostgroup_name remote linux-servers --这里我定义了一个新组，不能和localhost.cfg里的组同名，会冲突 alias remote Linux Servers members 10.1.1.3 } --下面是公共服务，这里我只写了四个，你可以自行增加 define service{ use local-service host_name 10.1.1.3 service_description PING check_command check_ping!100.0,20%!500.0,60% } define service{ use local-service host_name 10.1.1.3 service_description SSH check_command check_ssh } define service{ use local-service host_name 10.1.1.3 service_description HTTP check_command check_http } define service{ use local-service host_name 10.1.1.3 service_description FTP check_command check_ftp!1!3 } # nagios -v /etc/nagios/nagios.cfg # systemctl restart nagios ========================================================================== 例:监控远程的私有服务 10.1.1.2 10.1.1.3 nagios监控端 被监控linux check_disk check_nrpe －－－－－－－－－ check_nrpe check_swap SSL传输 check_load等 第一大步:nagios监控端上的操作 1,确认有如下的命令，如果没有，则yum install nagios-plugins-nrpe /usr/lib64/nagios/plugins/check_nrpe 2，增加check_nrpe命令到commands.conf文件里 # vim /etc/nagios/objects/commands.cfg define command{ command_name check_nrpe command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ } --c参数后接command， 也就说check_nrpe可以调用别的check命令 3，在nagios服务器上对10.1.1.3的配置文件增加远程私有服务 # vim /etc/nagios/objects/10.1.1.3.cfg define service{ use local-service host_name 10.1.1.3 service_description Current Users check_command check_nrpe!check_remote_users } --check_remote_users就是check_nrpe的C参数要调用的命令，此命令在nagios服务器上的commands.cfg里是不存在，它会在后面的步骤中加到被监控端 # systemctl restart nagios 4,用下面的命令做测试，但现在是会报对方5666端口拒绝(因为被监控端还没有安装配置) # /usr/lib64/nagios/plugins/check_nrpe -H 10.1.1.3 -c check_remote_users connect to address 10.1.1.3 port 5666: Connection refused connect to host 10.1.1.3 port 5666: Connection refused 第二大步:nagios被监控端上的操作 1,安装nrpe和其它监控命令包(需要本地,centos163,epel源) # yum install nrpe nagios-plugins-users 2,修改nrpe主配置文件 # vim /etc/nagios/nrpe.cfg allowed_hosts=10.1.1.2 --把默认的127.0.0.1改成nagios服务器的ip command[check_remote_users]=/usr/lib64/nagios/plugins/check_users -w 5 -c 10 --修改或增加这一行，主要是定义一个叫check_remote_users的命令（和服务器那边的配置对应) 3,启动服务，并检查5666端口是否开启 # systemctl restart nrpe # systemctl status nrpe # systemctl enable nrpe # lsof -i:5666 第三大步:回到nagios服务器端测试 再次使用下面的命令，就可以监控到远程的实际登录用户数了 # /usr/lib64/nagios/plugins/check_nrpe -H 10.1.1.3 -c check_remote_users USERS WARNING - 9 users currently logged in |users=9;5;10;0 最后，清firefox缓存，在firefox查看远程监控也正确了 ============================================================================= 练习:监控远程/分区，/boot分区,swap,cpu load等 ============================================================================= 邮件报警验证: 1,确认你至少有一个service为crital状态 2,保证nagios服务器能上公网，还有确认有mail命令了 3,# vim /etc/nagios/objects/contacts.cfg email [email protected]126.com --改成你的一个公网测试邮箱 4,# systemctl restart nagios 如果你想做成免费手机短信通知，可以使用类似139邮箱这种(有邮件到达就短信通知的功能)的邮箱 现在有智能手机就方便多了，直接报警邮件发给外部一个邮箱，然后在你的手机上下载对应邮箱的app软件就ok了 现在nagios官方直接都有手机客户端管理软件 ============================================================================= nagios图表插件一: nagiosgraph-1.4.4.tar.gz --此软件包最后的版本是2011年出的，目前在centos7测试过不兼容 以下这份文档是在rhel6.5上成功的文件（仅做参考) tar xf nagiosgraph-1.4.4.tar.gz -C /usr/src cd /usr/src/nagiosgraph-1.4.4 [[email protected] nagiosgraph-1.4.4]# ./install.pl --check-prereq checking required PERL modules Carp...1.11 CGI...3.51 Data::Dumper...2.124 File::Basename...2.77 File::Find...1.14 MIME::Base64...3.08 POSIX...1.17 RRDs... ***FAIL*** --没有rrd,就算你在rhel6上yum install *rrd* 再来测试也是fail Time::HiRes...1.9721 checking optional PERL modules GD...fail --没有gd,yum install *gd* 也不能搞定 checking nagios installation found nagios at /usr/local/nagios/bin/nagios checking web server installation found apache at /usr/sbin/httpd 安装gd tar xf libgd-2.1.0.tar.gz -C /usr/src/ cd /usr/src/libgd-2.1.0/ ./configure ;make ;make install echo /usr/local/lib >> /etc/ld.so.conf ldconfig tar xf GD-2.56.tar.gz -C /usr/src/ cd /usr/src/GD-2.56/ perl Build.PL ./Build ./Build install ldconfig 安装rrdtool #

vim /etc/nagios/objects/commands.cfg define command{ command_name process-service-perfdata-file command_line /bin/mv /usr/local/pnp4nagios/var/service-perfdata /usr/local/pnp4nagios/var/spool/service-perfdata.$TIMET$ } define command{ command_name process-host-perfdata-file command_line /bin/mv /usr/local/pnp4nagios/var/host-perfdata /usr/local/pnp4nagios/var/spool/host-perfdata.$TIMET$ } 第五步:启动npcd(我们现在使用的是bulk模式和npcd,一共五种模式，具体参考官档说明) # systemctl start npcd # chkconfig npcd on 第六步:定义模版，在templates.cfg子配置文件里最后空白地方复制粘贴下面的一段 # vim /etc/nagios/objects/templates.cfg define host { name hosts-pnp register 0 action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=_HOST_ } define service { name service-pnp register 0 action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$ } 第七步:apache的子配置文件修改（因为这个源码版对应的语法为apache2.2，而我们centos7.3上用的是apache2.4，所以需要改一下；还有就是我们的nagios使用的是rpm版，所以验证文件路径也改一下) # vim /etc/httpd/conf.d/pnp4nagios.conf Require all granted --把Order allow,deny\nAllow from all这两行删除，换成这句 AuthUserFile /etc/nagios/passwd --验证文件路径也改成这个 # systemctl restart httpd # systemctl enable httpd 第八步:把所有需要加图表功能的hosts和services加上图表需要的templates(hosts-pnp和service-php) # vim /etc/nagios/objects/localhost.cfg # vim /etc/nagios/objects/10.1.1.3.cfg --这两个配置里的hosts和services都可以加，效果如下示例: define host{ use linux-server,hosts-pnp --如这里加上hosts-pnp模版 host_name localhost alias localhost address 127.0.0.1 } define service{ use local-service,service-pnp --如这里加上service-pnp模版 service_description PING check_command check_ping!100.0,20%!500.0,60% } # nagios -v /etc/nagios/nagios.cfg # systemctl restart nagios 第九步:使用firefox访问测试 访问后，加了图表模版的hosts或services会有一个明显的图表图标，点进去，第一次会提示删除下面文件，删除后再点进去就ok了 # rm -rf /usr/local/pnp4nagios/share/install.php
