   • 网络协议监控(PING、SNMP等)
   • 日志文件监控
   • 数据库监控
   • 中间件监控(如JMX)
   • 云资源监控

2. 通知警报

   • 支持多种通知方式(邮件、短信、脚本执行等)
   • 支持基于阈值的警报触发
   • 支持多级别的通知escalation

3. 集中管理

   • 提供基于Web的管理界面
   • 支持分布式监控环境的中央管理
   • 支持LDAP/AD用户认证

4. 扩展性

   • 提供插件架构,支持自定义插件扩展

Nagios 核心是开源免费的,但其公司 Nagios Enterprises 也提供了商业版本和支持服务。Nagios 被广泛应用于各种规模的企业网络监控,是事实上的网络监控标准之一。

LTMP 环境安装

关于 LTMP 环境中的 Tengine 安装，请参考：在 ubuntu 22.04 中，通过源码编译安装 LTMP 中的 Tengine 服务（不支持 Lua 脚本语言）

关于 nagios 虚拟主机的配置如下：

server {
    listen 80;
    server_name _;

    # nginx 自带的 http_auth_request_module 认证模块，安装时需要编进去。可以使用 nginx -V 查看是否有该参数
    auth_basic "Nagios Access";
    auth_basic_user_file /usr/local/nagios/etc/.htpassword;

    location / {
        root /usr/local/nagios/share;
        index index.php;
    }

    location ~ \.php$ {
        root           /usr/local/nagios/share;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
    
    location /nagios {
      alias /usr/local/nagios/share;
    }
    location /cgi-bin/images {
      alias /usr/local/nagios/share/images;
    }
    location /cgi-bin/stylesheets {
      alias /usr/local/nagios/share/stylesheets;
    }
    location /cgi-bin {
      alias /usr/local/nagios/sbin;
    }
   location ~ .*\.(cgi|pl)?$ {
      gzip off;
      root /usr/local/nagios/sbin;
      rewrite ^/nagios/cgi-bin/(.*)\.cgi /$1.cgi break;
      fastcgi_pass unix:/usr/local/nginx/logs/perl-fcgi.sock;
      fastcgi_param SCRIPT_FILENAME /usr/local/nagios/sbin$fastcgi_script_name;
      fastcgi_index index.cgi;
      fastcgi_param REMOTE_USER $remote_user;
      fastcgi_param HTTP_ACCEPT_LANGUAGE en_US;
      include fastcgi_params;
      fastcgi_read_timeout 60;
    }
}

需要注意的是： 运行 nginx 的用户（ps aux|egrep ‘worker process’）必须和下面运行 start_perl_cgi.sh 中定义的用户一致，否则在 nginx 的错误日志中会出现 connect() to unix:/usr/local/nginx/logs/perl-fcgi.sock failed (13: Permission denied) 问题，进而影响 nagios web 端显示不正常的情况！！！

关于 LTMP 环境中的 MariaDB 安装，请参考：在 ubuntu 22.04 中，通过二进制安装 MariaDB 服务

这里不需要创建数据库信息！

关于 LTMP 环境中的 PHP 安装，请参考：在 ubuntu 22.04 中，通过源码编译安装 LNMP 中的 PHP 环境

        }
    }
}

在 /usr/local/nignx/ 目录下创建 start_perl_cgi.sh 文件，内容如下

#!/bin/bash
#set -x
dir=/usr/local/nginx/
   
stop ()
{
  #pkill  -f  $dir/perl-fcgi.pl
  kill $(cat $dir/logs/perl-fcgi.pid)
  rm $dir/logs/perl-fcgi.pid 2>/dev/null
  rm $dir/logs/perl-fcgi.sock 2>/dev/null
  echo "stop perl-fcgi done"
}
   
start ()
{
  rm $dir/now_start_perl_fcgi.sh 2>/dev/null
    
  chown nginx.nginx $dir/logs
  echo "$dir/perl-fcgi.pl -l $dir/logs/perl-fcgi.log -pid $dir/logs/perl-fcgi.pid -S $dir/logs/perl-fcgi.sock" >>$dir/now_start_perl_fcgi.sh
    
  chown nginx.nginx $dir/now_start_perl_fcgi.sh
  chmod u+x $dir/now_start_perl_fcgi.sh
    
  sudo -u nginx $dir/now_start_perl_fcgi.sh
  echo "start perl-fcgi done"
}
   
case $1 in
  stop)
    stop
    ;;
  start)
    start
    ;;
  restart)
    stop
    start
    ;;
esac

2.赋予两个脚本可执行权限：

chmod +x /usr/local/nginx/{perl-fcgi.pl,start_perl_cgi.sh}

3.启动 perl-cgi:

root@instance-2UkeKOzr:/usr/local/nginx# ./start_perl_cgi.sh start
start perl-fcgi done

4.确保在 nginx 日志目录 /usr/local/nginx/logs/ 目录下有生成 perl-fcgi.sock、perl-fcgi.log 以及 perl-fcgi.pid 三个文件：

root@instance-2UkeKOzr:/usr/local/nginx# ls -al logs/ |egrep -i perl
-rw-rw-r--  1 nginx nginx     581 May 11 07:32 perl-fcgi.log
-rw-rw-r--  1 nginx nginx       6 May 11 07:32 perl-fcgi.pid
srwxrwxr-x  1 nginx nginx       0 May 11 07:32 perl-fcgi.sock

nagios 安装

1.添加运行 nagios 系统用户：

useradd -s /sbin/nologin nagios

2.点击这里下载 Nagios Core 到服务器的 /usr/local/src/ 目录下：

wget -O /usr/local/src/nagios-4.5.2.tar.gz https://go.nagios.org/get-core/4-5-2/nagios-4.5.2.tar.gz

3.将下载的源码文件解压到下载目录

tar -zxf /usr/local/src/nagios-4.5.2.tar.gz -C /usr/local/src/

4.进入解压目录：

cd /usr/local/src/nagios-4.5.2

5.配置 ./configure 参数：

./configure --prefix=/usr/local/nagios  --with-nagios-user=nagios --with-nagios-group=nagios  --with-command-user=nagios --with-command-group=nagios

6.接下来，依次执行 make、make test、make install、make install-daemoninit、make install-init、make install-commandmode 以及 make install-config,如下：

makemake testmake installmake install-daemoninitmake install-initmake install-initmake install-configmake make install-webconf

执行 make :

root@instance-2UkeKOzr:/usr/local/src/nagios-4.5.2# make all 
d ./base && make
make[1]: Entering directory '/usr/local/src/nagios-4.5.2/base'
gcc -Wall -I.. -I. -I../lib -I../include  -I../include -I..  -g -O2 -I/usr/include/krb5 -I/usr/local/openssl/include -DHAVE_CONFIG_H -DNSCORE -c -o nagios.o ./nagios.c
... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... 
*** Compile finished ***

If the main program and CGIs compiled without any errors, you
can continue with testing or installing Nagios as follows (type
'make' without any arguments for a list of all possible options):

  make test
     - This runs the test suite

  make install
     - This installs the main program, CGIs, and HTML files

  make install-init
     - This installs the init script in /lib/systemd/system

  make install-daemoninit
     - This will initialize the init script
       in /lib/systemd/system

  make install-groups-users
     - This adds the users and groups if they do not exist

  make install-commandmode
     - This installs and configures permissions on the
       directory for holding the external command file

  make install-config
     - This installs *SAMPLE* config files in /usr/local/nagios/etc
       You'll have to modify these sample files before you can
       use Nagios.  Read the HTML documentation for more info
       on doing this.  Pay particular attention to the docs on
       object configuration files, as they determine what/how
       things get monitored!

  make install-webconf
     - This installs the Apache config file for the Nagios
       web interface

  make install-exfoliation
     - This installs the Exfoliation theme for the Nagios
       web interface

  make install-classicui
     - This installs the classic theme for the Nagios
       web interface


*** Support Notes *******************************************

If you have questions about configuring or running Nagios,
please make sure that you:

     - Look at the sample config files
     - Read the documentation on the Nagios Library at:
           https://library.nagios.com

before you post a question to one of the mailing lists.

执行 make test

1.在执行 make test 命令之前，先将 nagion 解压目录所属主和组都修改为 nagios, 否则执行 make test 会遇到 Error: Unable to write to check_result_path ('/usr/local/src/nagios-4.5.2/t/var/spool/checkresults') - Permission denied 的错误：

chown -R nagios:nagios /usr/local/src/nagios-4.5.2

2.在执行 make test

root@instance-2UkeKOzr:/usr/local/src/nagios-4.5.2# make test
cd ./base && make

Remember, these are *SAMPLE* config files.  You'll need to read
the documentation for more information on how to actually define
services, hosts, etc. to fit your particular needs.

最后，如果你使用的 Apache 作为 web 服务，则还需要执行 make install-webconf

Nagios web 端安装

1.(在没有安装 apache的 htpasswd 命令情况下 )打开网址 https://tool.oschina.net/htpasswd 生成帐号密码，然后将其复制；

2.在 nagios 安装目录 /usr/local/nagios/etc/ 下创建 .htpassword 的文件，将上面生成的账号密码内容复制粘贴到该文件中：

leazhi:$apr1$fcvOen3f$u1LdZ/UKrg33MowLbIJWd0

3.打开浏览器，输入服务器IP，然后输入上面的账号密码，访问 nagios 主页，如图：

nagios 配置

1.备份 /usr/local/nagios/etc/cgi.cfg 文件：

cp /usr/local/nagios/etc/cgi.cfg{,.bak}

2.授权 nagios web 端用户访问，否则 nagios 认证用户登陆后，无法访问到 nagios 监控内容：

sed -i 's/nagiosadmin/nagiosadmin,leazhi/g' /usr/local/nagios/etc/cgi.cfg

3.将 nagios 目录所属主和组都修改为 nagios ：

chown -R nagios:nagios /usr/local/nagios/

4.重启下 nagios:

systemctl restart nagios.service

Nagios Plugins 安装

1.点击这里下载 Nagios Plugins 到服务器的 /usr/local/src/ 目录下：

wget -O /usr/local/src/nagios-plugins-2.4.10.tar.gz https://nagios-plugins.org/download/nagios-plugins-2.4.10.tar.gz

2.将其解压至下载目录：

tar -zxf /usr/local/src/nagios-plugins-2.4.10.tar.gz -C /usr/local/src/

3.进入解压目录：

cd /usr/local/src/nagios-plugins-2.4.10

4.配置 ./configure 参数：

./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios

5.执行 make && make install 进行编译安装

make && make install

NRPE 安装

1.点击这里下载 NRPE 源码包 到服务器的 /usr/local/src/ 目录下：

wget -O /usr/local/src/nrpe-4.0.2.tar.gz https://github.com/NagiosEnterprises/nrpe/releases/download/nrpe-4.0.2/nrpe-4.0.2.tar.gz

2.将下载的源码文件解压到下载目录：

tar -zxf /usr/local/src/nrpe-4.0.2.tar.gz -C /usr/local/src/

3.进入解压目录：

cd /usr/local/src/nrpe-4.0.2/

4.配置 ./configure 参数：

root@instance-2UkeKOzr:/usr/local/src/nrpe-4.0.2# ./configure --prefix=/usr/local/nrpe 
checking for a BSD-compatible install... /usr/bin/install -c
checking what the operating system is ... linux
... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... 
*** Configuration summary for nrpe 4.0.2 2020-03-09 ***:

 General Options:
 -------------------------
 NRPE port:    5666
 NRPE user:    nagios
 NRPE group:   nagios
 Nagios user:  nagios
 Nagios group: nagios


Review the options above for accuracy.  If they look okay,
type 'make all' to compile the NRPE daemon and client
or type 'make' to get a list of make options.

也可以使用 make 命令列出 make 参数对应的功能：

root@instance-2UkeKOzr:/usr/local/src/nrpe-4.0.2# make

Please enter make [option] where [option] is one of:

     all                  builds nrpe and check_nrpe
     nrpe                 builds nrpe only
     check_nrpe           builds check_nrpe only
     install-groups-users add the users and groups if they do not exist
     install              install nrpe and check_nrpe
     install-plugin       install the check_nrpe plugin
     install-daemon       install the nrpe daemon
     install-config       install the nrpe configuration file
     install-inetd        install the startup files for inetd, launchd, etc.
     install-init         install the startup files for init, systemd, etc.

5.接下来依次执行 make all、make install、make install-plugin、make install-config 以及 make install-init：

make allmake installmake install-pluginmake install-configmake install-init

执行 make all:

root@instance-2UkeKOzr:/usr/local/src/nrpe-4.0.2# make all
cd ./src/; make
make[1]: Entering directory '/usr/local/src/nrpe-4.0.2/src'
