linux环境中nagios(nagios core)安装?nagios安装?

需求描述:

　　最近准备给线上生产环境部署监控平台,对各个系统的资源使用状况,服务进行监控,采用nagios core版本进行部署,

　　nagios core是开源版本的软件,是免费的nagios XI是上夜班.

环境信息:

　　操做系统版本:RedHat 7.0 x64

安装过程:

1.将SElinx设置为disabled或者permissive

[root@testvm02 ~]# sed -i 's/SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config

[root@testvm02 ~]# getenforce

Permissive

2.安装依赖的软件包

yum install -y gcc glibc glibc-common wget unzip httpd php gd gd-devel perl postfix

3.下载,上传nagios-core的软件包

下载地址:https://www.nagios.org/downloads/nagios-core/thanks/?skip=1&product_download=nagioscore-source

cd /usr/local/src

wget https://assets.nagios.com/downloads/nagioscore/releases/nagios-4.4.1.tar.gz#_ga=2.110152902.27871981.1533304858-616462593.1533304858

本例安装的版本:

nagios-4.4.1.tar.gz

上传软件到指定的目录中:

4.解压,编译,安装

[root@testvm02 nagios-4.4.1]# tar zxf nagios-4.4.1.tar.gz

[root@testvm02 nagios-4.4.1]# cd nagios-4.4.1

[root@testvm02 nagios-4.4.1]# ./configure

[root@testvm02 nagios-4.4.1]# make all

5.建立用户,用户组

[root@testvm02 nagios-4.4.1]# make install-groups-users

groupadd -r nagios

useradd -g nagios nagios

[root@testvm02 nagios-4.4.1]# usermod -a -G nagios apache

[root@testvm02 nagios-4.4.1]# id nagios

uid=500(nagios) gid=499(nagios) groups=499(nagios)

[root@testvm02 nagios-4.4.1]# id apache

uid=48(apache) gid=48(apache) groups=48(apache),499(nagios

6.建立二进制命令,CGI,html文件

root@testvm02 nagios-4.4.1]# make install

7.安装相关的进程文件(安装启动脚本),增长httpd开机启动,nagios开机启动

[root@testvm02 nagios-4.4.1]# make install-daemoninit

/usr/bin/install -c -m 755 -d -o root -g root /etc/init.d

/usr/bin/install -c -m 755 -o root -g root startup/default-init /etc/init.d/nagios

*** Init script installed ***

[root@testvm02 nagios-4.4.1]# systemctl enable httpd.service

[root@testvm02 nagios-4.4.1]# systemctl list-unit-files  | grep httpd

httpd              0:off    1:off    2:on    3:on    4:on    5:on    6:off

[root@testvm02 nagios-4.4.1]# systemctl list-unit-files  | grep nagios

nagios             0:off    1:off    2:on    3:on    4:on    5:on    6:off

8.安装外部命令文件

[root@testvm02 nagios-4.4.1]# make install-commandmode

/usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/var/rw

chmod g+s /usr/local/nagios/var/rw

*** External command directory configured ***

9.安装配置文件

[root@testvm02 nagios-4.4.1]# make install-config

/usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/etc

/usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/etc/objects

/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/nagios.cfg /usr/local/nagios/etc/nagios.cfg

/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/cgi.cfg /usr/local/nagios/etc/cgi.cfg

/usr/bin/install -c -b -m 660 -o nagios -g nagios sample-config/resource.cfg /usr/local/nagios/etc/resource.cfg

/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/templates.cfg /usr/local/nagios/etc/objects/templates.cfg

/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/commands.cfg /usr/local/nagios/etc/objects/commands.cfg

/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/contacts.cfg /usr/local/nagios/etc/objects/contacts.cfg

/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/timeperiods.cfg /usr/local/nagios/etc/objects/timeperiods.cfg

/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/localhost.cfg /usr/local/nagios/etc/objects/localhost.cfg

/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/windows.cfg /usr/local/nagios/etc/objects/windows.cfg

/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/printer.cfg /usr/local/nagios/etc/objects/printer.cfg

/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/switch.cfg /usr/local/nagios/etc/objects/switch.cfg

*** Config files installed ***

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.

备注:这些都是一些示例配置文件,同时好比nagios.cfg在启动nagios的时候须要使用到.

10.安装apache配置文件即httpd配置文件

[root@testvm02 nagios-4.4.1]# make install-webconf

/usr/bin/install -c -m 644 sample-config/httpd.conf /etc/httpd/conf.d/nagios.conf

if [ 0 -eq 1 ]; then \    ln -s /etc/httpd/conf.d/nagios.conf /etc/apache2/sites-enabled/nagios.conf; \fi

*** Nagios/Apache conf file installed ***

11.配置防火墙或者关闭防火墙

配置容许8端口进入:

iptables -I INPUT -p tcp --destination-port 80 -j ACCEPT

service iptables save

关闭防火墙,关闭开机启动:

service iptables stop

[root@testvm02 nagios-4.4.1]# chkconfig --level 2345 iptables off

[root@testvm02 nagios-4.4.1]# chkconfig --list | grep iptables

iptables           0:off    1:off    2:off    3:off    4:off    5:off    6:of

12.建立nagios管理帐号

[root@testvm02 nagios-4.4.1]# htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin

New password:                           #输入新密码

Re-type new password:                   #再次输入密码,进行确认

Adding password for user nagiosadmin

13.启动apache服务,nagios core服务

[root@testvm02 nagios-4.4.1]# service httpd start

[root@testvm02 nagios-4.4.1]# service nagios start

14.经过页面进行访问测试

访问地址:http://192.168.53.25/nagios    输入nagios管理帐号,密码进行登陆.

登陆成功以后,页面以下:

查看Hosts,Services有以下的报错:

备注:以上错误提示,表示没有某些命令,即在/usrlocal/nagios/libexex中灭有命令,须要安装nagios-plugins来安装相应的命令

15.下载,上传nagios-plugins压缩包

软件包:nagios-plugins-2.2.1.tar.gz下载地址: https://www.nagios.org/downloads/nagios-plugins/

cd /usr/local/src

wget https://nagios-plugins.org/download/nagios-plugins-2.2.1.tar.gz#_ga=2.22070264.27871981.1533304858-616462593.1533304858

cd /opt/softwares/;ls -l nagios-plugins*

-rw-r--r--. 1 root root 2728818 Jul 31 12:25 nagios-plugins-2.2.1.tar.gz

16.安装依赖的软件包,解压,编译,安装

yum install -y gcc glibc glibc-common make gettext automake autoconf wget openssl-devel net-snmp net-snmp-utils

 tar zxf nagios-plugins-2.2.1.tar.gz 

 cd nagios-plugins-2.2.1

./configure 

make

make install

备注:插件安装完成

17.从新在nagios页面进行测试,在HOSTS中的localhost的命令菜单中点击."Re-schedule the next check",查看hosts状态

备注:说明命令已经成功,对于services中的检查,也会在必定时间以后,达到调度时间进行状态的修改.

Servies的状态:

18.针对HTTP的检查,在本地的/var/www/html中建立index.html文件就能够解决这个警告

[root@testvm02 libexec]# cd /var/www/html/

[root@testvm02 html]# touch index.html

 配置完成以后,http服务的状态:

到此,全部的nagios-core,nagios-plugins已经安装完成!

nagios core not running 解决

手工方式启动nagios

# /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg（解决）

主要是apache没有开启cgi脚本的缘故

进入apache的主配置文件httpd.conf

#LoadModule cgid_module modules/mod_cgid.so

#LoadModule actions_module modules/mod_actions.so
