nagios+pnp4nagios+nagiosql

                                 Nagios+PNP4nagios+Nagiosql

1.首先安装下面的包：

yum install  libjpeg-devel libpng-devel pango* libart_lgpl-devel pango-devel* cairo-devel* libxml2-devel libjpeg-devel libpng-devel php-gd gd-devel perl-GD libtoul-ltdl-devel rrdtool-perl perl-devel perl-ExtUtils-Embed perl-Time-HiRes yum groupinstall "Development Tools" libjpeg-devel libpng-devel pango* libart_lgpl-devel pango-devel* cairo-devel* libxml2-devel libjpeg-devel libpng-devel php-gd gd-devel perl-GD libtoul-ltdl-devel rrdtool-perl perl-devel perl-ExtUtils-Embed perl-Time-HiRes

2.接着我们再安装下面的包

yum install httpd gd gd-devel php php-mysql mysql-devel  mysql mysql-server gcc glibc glibc-common

注：原机器有的包，可以通过rpm -qa|grep 包名 检查下，如有上述包的可以不装。

3.添加nagios运行所需的用户和组

groupadd nagcmd

useradd -G nagcmd nagios

passwd nagios

4.把apache也添加到nagcmd的组里

usermod-a -G nagcmd apache

5.编译安装nagios

tar -zxvf nagios-3.5.1.tar.gz

./configure --with-command-group=nagcmd --enable-event-broker

*** Configuration summary for nagios 3.5.1 08-30-2013 ***:

make install#安装

*** Main program, CGIs and HTML files installed ***

You can continue with installing Nagios as follows (type 'make'
without any arguments for a list of all possible options):

  make install-init
     - This installs the init script in /etc/rc.d/init.d

  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

make[1]: Leaving directory `/usr/local/src/nagios'

make install-init#安装开机启动脚本

cp -rf contrib/exfoliation/stylesheets/* /usr/local/nagios/share/stylesheets
cp -rf contrib/exfoliation/images/* /usr/local/nagios/share/images

6.关闭 selinux

6.1编辑配置文件#永久生效，需要重启机器

vim /etc/sysconfig/selinux

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled#把这行的改成disabled
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

6.2写进内核，立即生效，重启机器后会失效

setenforce 0

7.创建密码认证文件

htpasswd -c/usr/local/nagios/etc/htpasswd.users nagiosadmin#创建用于web的登录的文件

注：该命令的执行要到安装的nagios的目录下，这里是/usr/local/nagios

[root@localhost nagios]# htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
New password:
Re-type new password:
Adding password for user nagiosadmin

8. 启动服务

service httpd start

9.把nagios加入服务

chkconfig --add nagios#加为服务

chkconfig nagios on#设为开机启动

10.安装nagios-plugins

 tar -zxvf nagios-plugins-1.4.15.tar.gz#解压文件

./configure--with-nagios-user=nagios --with-nagios-group=nagios #配置nagios插件

--with-apt-get-command:
              --with-ping6-command: /bin/ping6 -n -U -w %d -c %d %s
               --with-ping-command: /bin/ping -n -U -w %d -c %d %s

                     --with-cgiurl: /nagios/cgi-bin
               --with-trusted-path: /bin:/sbin:/usr/bin:/usr/sbin
                   --enable-libtap: no

make&&make install#编译安装

/usr/bin/install -c -o nagios -g nagios 'check_breeze' '/usr/local/nagios/libexec/check_breeze'
 /usr/bin/install -c -o nagios -g nagios 'check_disk_smb' '/usr/local/nagios/libexec/check_disk_smb'
 /usr/bin/install -c -o nagios -g nagios 'check_flexlm' '/usr/local/nagios/libexec/check_flexlm'
 /usr/bin/install -c -o nagios -g nagios 'check_ircd' '/usr/local/nagios/libexec/check_ircd'

 /usr/bin/install -c -o nagios -g nagios 'utils.pm' '/usr/local/nagios/libexec/utils.pm'

装完/usr/local/nagios/libexec目录下应该有下面的一些插件

[root@localhost libexec]# ls
check_apt      check_disk_smb  check_ide_smart     check_mailq        check_nt        check_pop      check_ssh    check_wave
check_breeze   check_dns       check_ifoperstatus  check_mrtg         check_ntp       check_procs    check_ssmtp  negate

check_disk     check_icmp      check_log           check_nntps        check_ping      check_spop     check_users

11.登录nagios界面

注：要关闭主机防火墙，或者在防火墙中开放主机web的访问端口。

在浏览器中输入http://服务器IP/nagios,输入nagiosadmin,和刚才设置的密码。

安装成功。

12.安装nrpe#nagios监控远程的机器必须用nrpe,所以我们这边装nrpe这个插件，要说的一点是nagios服务器只需装nrpe 插件，不需要装nrpe demon也就是守护进程。并且nrpe不需要启动服务的。

tar -zxvf nrpe-2.15.tar.gz

./configure --with-nrpe-user=nagios \

> --with-nrpe-group=nagios \

> --with-nagios-user=nagios \

> --with-nagios-group=nagios \

> --enable-command-args \#改命令必须加，需要使用nrpe后面加参数

> --enable-ssl

*** Configuration summary for nrpe 2.15 09-06-2013 ***:

 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.

make all

*** Compile finished ***

If the NRPE daemon and client compiled without any errors, you
can continue with the installation or upgrade process.

Read the PDF documentation (NRPE.pdf) for information on the next
steps you should take to complete the installation or upgrade.

make install-plugin

[root@localhost nrpe-2.15]# make install-plugin
cd ./src/ && make install-plugin
make[1]: Entering directory `/usr/local/src/nrpe-2.15/src'
/usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/libexec
/usr/bin/install -c -m 775 -o nagios -g nagios check_nrpe /usr/local/nagios/libexec
make[1]: Leaving directory `/usr/local/src/nrpe-2.15/src'

在本地主机测试远程的服务

[root@localhost libexec]# ./check_nrpe -H192.168.1.10

NRPE v2.15#测试成功

注意：监控端（服务器）的nrpe可以不启动服务，5666的端口不可以被占用。防火墙打开的话要开放5666端口的访问。nrpe通信双方的版本要一样的。监控客户机的nrpe要以守护进程的方式启动。

13.安装pnp4nagios是一个基于php和perl，用rrdtool将nagios采集的数据绘制图表的工具，

所以这里我们来安装rrdtool。

tar -xzf rrdtool-1.4.8.tar.gz 

cd rrdtool-1.4.8

./configure --prefix=/usr/local/rrdtool

config is DONE!

-rwxr-xr-x 1 root root 295195 10月 28 18:33 rrdupdate

14.安装pnpnagios

tar -zxvf pnp4nagios-0.6.25.tar.gz

./configure --with-nagios-user=nagios --with-nagios-group=nagios --with-rrdtool=/usr/local/rrdtool/bin/rrdtool#加上rrdtool的路径

*** Configuration summary for pnp4nagios-0.6.25 03-01-2015 ***

  General Options:
  -------------------------         -------------------

  -------------------------         -------------------
  HTML URL:                         http://localhost/pnp4nagios
  Apache Config File:               /etc/httpd/conf.d/pnp4nagios.conf

  Review the options above for accuracy.  If they look okay,
  type 'make all' to compile.

 make all

*** Compile finished ***

  make install
     - This installs the main program and HTML files

  make fullinstall
     - This installs the main program, runlevel scripts, config and HTML files

Enjoy.

make install#普通安装

*** Main program, Scripts and HTML files installed ***

Please run 'make install-webconf' to install the
web configuration file

Please run 'make install-config' to install sample
configuration files

Please run 'make install-init' if you want to use

make[1]: Leaving directory `/usr/local/src/pnp4nagios-0.6.25/scripts'

注意：也可以在上面的配置完的选项中直接make fullinstall

15. 进入到pnp4nagios的目录/usr/local/pnp4nagios/etc中，把相关后缀带sample文件变更成无sample后缀

  例如：mvweb_traffic.cfg-sample web_traffic.cfg

16.配置Ｎagios来启用PNP4nagios

pnp4nagios有五种工作模式，常用的有三种

如下图所示：

16.1.Synchronous Mode

nagios.cfg 文件里改

process_performance_data=1

enable_environment_macros=1

service_perfdata_command=process-service-perfdata

host_perfdata_command=process-host-perfdata

command.cfg文件里改

define command {
       command_name    process-service-perfdata
       command_line    /usr/bin/perl /usr/local/pnp4nagios/libexec/process_perfdata.pl
}

define command {
       command_name    process-host-perfdata
       command_line    /usr/bin/perl /usr/local/pnp4nagios/libexec/process_perfdata.pl -d HOSTPERFDATA

}

注：template.cfg和定义的host.cfg里要把添加的主机模板和服务模板都加进去。这里我先介绍下几种模式。具体的模板和主机的改法我会在下面介绍。

16.2.Bulk Mode

nagios.cfg里改

注意：下面的改法，可以在原本注释的文件里去掉注释，也可以直接复制过来加在文件的最后面。

 process_performance_data=1

#
# service performance data
#
service_perfdata_file=/usr/local/pnp4nagios/var/service-perfdata
service_perfdata_file_template=DATATYPE::SERVICEPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tSERVICEDESC::$SERVICEDESC$\tSERVICEPERFDATA::$SERVICEPERFDATA$\tSERVICECHECKCOMMAND::$SERVICECHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$\tSERVICESTATE::$SERVICESTATE$\tSERVICESTATETYPE::$SERVICESTATETYPE$
service_perfdata_file_mode=a
service_perfdata_file_processing_interval=15
service_perfdata_file_processing_command=process-service-perfdata-file

#
# host performance data starting with Nagios 3.0
#
host_perfdata_file=/usr/local/pnp4nagios/var/host-perfdata
host_perfdata_file_template=DATATYPE::HOSTPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tHOSTPERFDATA::$HOSTPERFDATA$\tHOSTCHECKCOMMAND::$HOSTCHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$
host_perfdata_file_mode=a
host_perfdata_file_processing_interval=15
host_perfdata_file_processing_command=process-host-perfdata-file

commands.cfg里改

define command{
       command_name    process-service-perfdata-file
       command_line    /usr/local/pnp4nagios/libexec/process_perfdata.pl --bulk=/usr/local/pnp4nagios/var/service-perfdata
}

define command{
       command_name    process-host-perfdata-file
       command_line    /usr/local/pnp4nagios/libexec/process_perfdata.pl --bulk=/usr/local/pnp4nagios/var/host-perfdata
}

16.3.Bulk Mode with NPCD

process_performance_data=1

#
# service performance data
#
service_perfdata_file=/usr/local/pnp4nagios/var/service-perfdata
service_perfdata_file_template=DATATYPE::SERVICEPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tSERVICEDESC::$SERVICEDESC$\tSERVICEPERFDATA::$SERVICEPERFDATA$\tSERVICECHECKCOMMAND::$SERVICECHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$\tSERVICESTATE::$SERVICESTATE$\tSERVICESTATETYPE::$SERVICESTATETYPE$
service_perfdata_file_mode=a
service_perfdata_file_processing_interval=15
service_perfdata_file_processing_command=process-service-perfdata-file

#
# host performance data starting with Nagios 3.0
#
host_perfdata_file=/usr/local/pnp4nagios/var/host-perfdata
host_perfdata_file_template=DATATYPE::HOSTPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tHOSTPERFDATA::$HOSTPERFDATA$\tHOSTCHECKCOMMAND::$HOSTCHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$
host_perfdata_file_mode=a
host_perfdata_file_processing_interval=15
host_perfdata_file_processing_command=process-host-perfdata-file

command.cfg更改

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.$TIMET$
}

npcd启动方式： /usr/local/pnp4nagios/bin/npcd -d -f /usr/local/pnp4nagios/etc/npcd.cfg

16.4.Bulk Mode with NPCD and npcdmod

16.5.Gearman Mode

这两种模式就先不介绍了，一般用不到。想了解的话，详见官网：https://docs.pnp4nagios.org/pnp-0.6/config

pnp4nagios有很多种工作模式，这里我们选用Bulk模式，这里先把pnp4nagios执行数据收集的文件拷贝到nagios的libexec下，方便统一命令的执行路径．

cp/usr/local/pnp4nagios/libexec/process_perfdata.pl /usr/local/nagios/libexec/

 

其实在/usr/local/pnp4nagios/etc下的nagios.cfg的文件里已经有了对bulk等模式的定义，我们打开nagios.cfg的文件看看。注意：是在/usr/local/pnp4nagios/etc下的nagios.cfg

#
# Bulk / NPCD mode
#

process_performance_data=1

# *** the template definition differs from the one in the original nagios.cfg
#
service_perfdata_file=/usr/local/pnp4nagios/var/service-perfdata
service_perfdata_file_template=DATATYPE::SERVICEPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tSERVICEDESC::$SERVICEDESC$\tSERVICEPERFDATA::$SERVICEPERFDATA$\tSERVICECHECKCOMMAND::$SERVICECHECKCOMMAND$\tHOSTSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$\tSERVICESTATE::$SERVICESTATE$\tSERVICESTATETYPE::$SERVICESTATETYPE$
service_perfdata_file_mode=a
service_perfdata_file_processing_interval=15
service_perfdata_file_processing_command=process-service-perfdata-file

# *** the template definition differs from the one in the original nagios.cfg
#
host_perfdata_file=/usr/local/pnp4nagios/var/host-perfdata
host_perfdata_file_template=DATATYPE::HOSTPERFDATA\tTIMET::$TIMET$\tHOSTNAME::$HOSTNAME$\tHOSTPERFDATA::$HOSTPERFDATA$\tHOSTCHECKCOMMAND::$HOSTCHECKCOMMAND$\tHO
STSTATE::$HOSTSTATE$\tHOSTSTATETYPE::$HOSTSTATETYPE$
host_perfdata_file_mode=a
host_perfdata_file_processing_interval=15
host_perfdata_file_processing_command=process-host-perfdata-file

然后修改 /usr/local/nagios/etc/commands.cfg文件，修改命令如下

注意：这两个命令可以定义到配置文件的最下面，把本来机器上带的# 'process-host-perfdata' command definition 注释掉

#
# Bulk mode
#
#define command {
#       command_name    process-service-perfdata-file
#       command_line    /usr/local/pnp4nagios/libexec/process_perfdata.pl --bulk /usr/local/pnp4nagios/var/service-perfdata
#}

#define command {
#       command_name    process-host-perfdata-file
#       command_line    /usr/local/pnp4nagios/libexec/process_perfdata.pl --bulk /usr/local/pnp4nagios/var/host-perfdata
#}

然后修改/usr/local/nagios/etc/templates.cfg文件

define host {
   name       host-pnp    action_url    /pnp4nagios/index.php/graphhost=$HOSTNAME$&srv=_HOST_'rel='/pnp4nagios/index.php/popup?host=$HOSTNAME$&srv=_HOST_

   process_perf_data  1
   register   0

}

define service { 
  name       srv-pnp 
action_url       /pnp4nagios/index.php/graphhost=$HOSTNAME$&srv=$SERVICEDESC$'rel='/pnp4nagios/index.php/popup?host=$HOSTNAME$&srv=$SERVICEDESC$

  process_perf_data  1
   register   0
}

注意：要把process_perf_data  1加进去。

然后修改需要的主机这里以/usr/local/nagios/etc/localhost.cfg

这里我就简单的举几个例子。

# Define a host for the local machine

define host{
        use                     linux-server,host-pnp #加上模板           ; Name of host template to use
                                                        ; This host definition will inherit all variables that are defined
                                                        ; in (or inherited by) the linux-server host template definition.
        host_name               localhost
        alias                   localhost
        address                 127.0.0.1
        }

# Define a service to "ping" the local machine

define service{
        use                             local-service,srv-pnp         ; Name of service template to use
        host_name                       localhost
        service_description             PING
        check_command                   check_ping!100.0,20%!500.0,60%
        }

17.然后添加小太阳模版，镶嵌在nagios页面上

你只需要把鼠标移动到太阳图标上面就会自动弹出图形出来

拷贝status-header.ssi到/usr/local/nagios/share/ssi/目录下面来（这一步很重要，要不然移动到太阳标记上出不来图）到pnp4原安装的目录的Contrib目录下拷贝。

cp status-header.ssi/usr/local/nagios/share/ssi/

18.检查nagios配置并重启服务。

service npcd start

service nagios restart

service httpd restart

效果如下图所示：

已经出图，证明pnp4nagios安装成功！

19.下面我们来安装nagiosql

tar -zxvf nagiosql_311.tar.gz

mv nagiosql /usr/local/nagios/#把解压出来的文件，迁移到/usr/local/nagios/下面

20. 建立nagiosql导出nagios配置文件的目录并修改权限

mkdir -p/etc/nagiosql/{hosts,services,backup/{,hosts,services},import}

chown -R apache:nagios /etc/nagiosql/

chmod -R 755 /etc/nagiosql

chmod 777 /usr/local/nagios/nagiosql/config

21.  Nagios相关文件权限的设定

chown nagios:apache /usr/local/nagios/etc

chown nagios:apache /usr/local/nagios/etc/{nagios.cfg,cgi.cfg}

chown nagios:apache /usr/local/nagios/etc/*

chmod 664 /usr/local/nagios/etc/{nagios.cfg,cgi.cfg}

chmod 775 /usr/local/nagios/etc

 22. 设定nagios二进制文件的权限，以便其能够通过Web程序执行

chown nagios:apache /usr/local/nagios/bin/nagios

chmod 750 /usr/local/nagios/bin/nagios

chown -R apache.nagios /usr/local/nagios/var/spool/

chown nagios:apache /usr/local/nagios/var/rw/nagios.cmd

chmod 660 /usr/local/nagios/var/rw/nagios.cmd

23. 为apache添加nagiosQL虚拟目录
vim /etc/httpd/conf.d/nagios.conf 最后增加如下内容：

Alias /nagiosQL "/usr/local/nagios/nagiosql"

<Directory "/usr/local/nagios/nagiosql">

# SSLRequireSSL

Options None

AllowOverride None

Order allow,deny

Allow from all

</Directory>

24. 建立nagiosql安装文件

 touch /usr/local/nagios/nagiosql/install/ENABLE_INSTALLER

25.  重启httpd服务

   service httpd restart

26.会看见出现nagiosql管理界面

进去把页面设置为中文。

27.  登入管理界面

（1）.管理域，配置对一些域的参数。

           

（2）工具－导入数据 右边会列出一些配置文件，选择导入即可。
导入只是把配置文件内容导入到Mysql数据库，而使用其配置文件时，是一个个cfg文件，所以下面要进行写入过程，写完并检查写入文件。

（3）检查配置并重启nagios

（4）写入之后就可以看到相应的cfg文件了，查看写入是否成功

ll /etc/nagiosql

(5) 修改nagios的配置文件，将原有以cfg_file开头项全部注释掉，加入面新写入的配置文件

加入新的配置文件路径
cfg_dir=/etc/nagiosql/hosts/
cfg_dir=/etc/nagiosql/services/
cfg_file=/etc/nagiosql/commands.cfg
cfg_file=/etc/nagiosql/contactgroups.cfg
cfg_file=/etc/nagiosql/contacts.cfg
cfg_file=/etc/nagiosql/contacttemplates.cfg
cfg_file=/etc/nagiosql/hostdependencies.cfg
cfg_file=/etc/nagiosql/hostescalations.cfg
cfg_file=/etc/nagiosql/hostextinfo.cfg
cfg_file=/etc/nagiosql/hostgroups.cfg
cfg_file=/etc/nagiosql/hosttemplates.cfg
cfg_file=/etc/nagiosql/servicedependencies.cfg
cfg_file=/etc/nagiosql/serviceescalations.cfg
cfg_file=/etc/nagiosql/serviceextinfo.cfg
cfg_file=/etc/nagiosql/servicegroups.cfg
cfg_file=/etc/nagiosql/servicetemplates.cfg
cfg_file=/etc/nagiosql/timeperiods.cfg

(6)  定义要监控的命令

例如：nrpe

(7) 添加要监控的主机。

（8）添加要监控的服务

注意：主机的模板要加上host-pnp,服务的模板srv-pnp都要加上。监控端命令行配置的命令，要与被监控端的nrpe.cfg配置的文件一致。

（9） 重启nagios,看看显示效果。

先要导入配置：

然后点 “工具”-"nagios控制“再执行下图所示的几个步骤：

(10) 执行完，会有下图所示的效果：

(11)添加监控mysql数据库服务

mysql> create database nagdb defaultCHARSET=utf8;

Query OK, 1 row affected(0.01 sec)

 

mysql> grant select on nagdb.* to 'nagios'@'%';

Query OK, 0 rows affected (0.00 sec)

 

mysql> update mysql.user set password =password('nagios') where user='nagios';

Query OK, 2 rows affected (0.00 sec)

Rows matched: 2  Changed: 2 Warnings: 0

 

mysql> flush privileges;

Query OK, 0 rows affected (0.00 sec)

 

mysql> quit

Bye

[root@localhost libexec]# ./check_mysql -H127.0.0.1 -u nagios -d nagdb -p nagios;

Uptime: 150 Threads: 1  Questions: 8  Slow queries: 0  Opens: 15 Flush tables: 1  Open tables:8  Queries per second avg: 0.53

然后定义监控的命令

定义要监控的主机和服务

导入定义好的数据

按照以下的几个步骤：写入检测数据、写入其他数据、检查配置文件、重启nagios

检测效果：

（12） 添加告警邮件设置：

   先定义联系人

    再定义需监控的主机

   再定义需监控的服务

   检查服务也设置一下

主机的检查也设置下

然后重启一下nagios服务
