nagios+centreon監控構建

發布時間：2020-05-31 00:44:59 來源：網絡閱讀：3881 作者：神雕奇俠欄目：移動開發

監控系統是運維人員的一個重要工具，熟悉其的構建與應用必不可少。nagios與centreon的搭

配是開源軟件最佳選擇。現在將我的構建與應用過程記錄如下。

一.環境預安裝

1.獲取主軟件包

wget http://jaist.dl.sourceforge.net/project/nagios/nagios-3.x/nagios-3.5.0/nagios-3.5.0.tar.gz
wget http://download.centreon.com/centreon/centreon-2.4.2.tar.gz
wget http://nchc.dl.sourceforge.net/project/nagiosplug/nagiosplug/1.4.16/nagios-plugins-1.4.16.tar.gz
wget http://nchc.dl.sourceforge.net/project/nagios/ndoutils-1.x/ndoutils-1.5.2/ndoutils-1.5.2.tar.gz
wget http://svn.centreon.com/trunk/ndoutils-patch/ndoutils1.5.2_light.patch
wget http://nchc.dl.sourceforge.net/project/nagios/nrpe-2.x/nrpe-2.14/nrpe-2.14.tar.gz

2.安裝第三方源

[root@localhost ~]# wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-1.el6.rf.i686.rpm
[root@localhost ~]#rpm -ivh rpmforge-release-0.5.2-1.el6.rf.i686.rpm

如果不安裝第三方源會導致相關軟件包不能安裝，進而導致主安裝出現相關問題。

3.安裝相關軟件包

安裝apache

[root@localhost ~]# yum -y install httpd
[root@localhost ~]# usermod -U apache
[root@localhost ~]# service httpd start

[root@localhost ~]# yum install mysql-devel openssl-devel mysql-server
[root@localhost ~]# service mysqld start
[root@localhost ~]# mysqladmin -u root password '123456'

在/etc/my.conf中的[mysqld]加入

innodb_file_per_table=1

否則在web安裝第七步時會有提示。

安裝php
[root@localhost ~]# yum -y install php php-mysql php-gd php-ldap php-xml php-mbstring
[root@localhost ~]# yum -y install gd fontconfig-devel libjpeg-devel libpng-devel gd-devel perl-GD

RRDTools
[root@localhost ~]# yum -y install rrdtool perl-rrdtool

安裝perl
[root@localhost ~]# yum -y install perl-Config-IniFiles perl-DBI perl-DBD-MySQL

安裝SNMP
[root@localhost ~]# yum -y install perl-Crypt-DES perl-Digest-SHA1 perl-Digest-HMAC net-snmp-utils
[root@localhost ~]# yum -y install perl-Socket6 perl-IO-Socket-INET6 net-snmp net-snmp-libs php-snmp dmidecode lm_sensors perl-Net-SNMP net-snmp-perl

安裝PEAR
[root@localhost ~]# yum -y install php-pear
[root@localhost ~]# pear channel-update pear.php.net
[root@localhost ~]# pear install --force PEAR-1.9.1
[root@localhost ~]# pear upgrade-all

二. 主軟件包安裝

nagios主要監控系統與網絡信息，同時監控遠程與本地主機及相關服務，還提供信息異常功能

1.安裝nagios

添加相關用戶及組

[root@localhost ~]# useradd -m nagios
[root@localhost ~]# passwd nagios
更改用戶 nagios 的密碼。
新的密碼：
無效的密碼：過于簡單化/系統化
無效的密碼：過于簡單
重新輸入新的密碼：
passwd：所有的身份驗證令牌已經成功更新。
[root@localhost ~]# groupadd nagcmd
[root@localhost ~]# usermod -G nagios,nagcmd nagios
[root@localhost ~]# usermod -G nagios,nagcmd apache

安裝nagios

[root@localhost monitor]# tar -zxvf nagios-3.5.0.tar.gz
[root@localhost nagios]# ./configure --prefix=/usr/local/nagios --with-command-group=nagcmd --enable-nanosleep --enable-event-broker --enable-embedded-perl
[root@localhost nagios]# make all
[root@localhost nagios]# make install
[root@localhost nagios]# make install-init
[root@localhost nagios]# make install-commandmode
[root@localhost nagios]# make install-config
[root@localhost nagios]# /etc/init.d/nagios start

nagios如果少了其插件，將什么也做不了，其功能主要通過插件來完成的。

2.nagios-pluigns安裝

[root@localhost monitor]# tar -zxvf nagios-plugins-1.4.16.tar.gz
[root@localhost nagios-plugins-1.4.16]# ./configure --with-nagios-user=nagios --with-nagios-group=nagios --with-openssl=/usr/bin/openssl --enable-perl-modules
[root@localhost nagios-plugins-1.4.16]# make && make install

3.ndoutils安裝

ndoutils主要將相關數據存儲到數據庫，ndoutils非常重要。

[root@localhost ndoutils-1.5.2]# tar -zxvf ndoutils-1.5.2.tar.gz
[root@localhost ndoutils-1.5.2]# patch -p1 -N < ndoutils1.5.2_light.patch
[root@localhost ndoutils-1.5.2]# ./configure --prefix=/usr/local/nagios/ --enable-mysql --with-ndo2db-user=nagios --with-ndo2db-group=nagios
[root@localhost ndoutils-1.5.2]# make && make install
[root@localhost ndoutils-1.5.2]# cp daemon-init /etc/init.d/ndo2db
[root@localhost ndoutils-1.5.2]# chmod 755 /etc/init.d/ndo2db
[root@localhost ndoutils-1.5.2]# cp config/ndo2db.cfg-sample /usr/local/nagios/etc/ndo2db.cfg
[root@localhost ndoutils-1.5.2]# /etc/init.d/ndoutils start

4.centreon安裝

centreon以web方式展現給用戶，通過第三方軟件實現對網絡，應用程序，主機的監控。

注：如下安裝過程只做參考，其不是第一次安裝，與第一次安裝可能有所不同，第一次安裝時會更新相關模塊。

文本安裝

[root@localhost monitor]# tar -zxvf centreon-2.4.2.tar.gz

[root@localhost centreon-2.4.2]# ./install.sh -i

web安裝

(1)centreon的歡迎界面

(2)檢查依賴關系

(3)配置nagios信息

(4)配置ndoutils模塊

(5)配置admin用戶

(6)配置數據庫信息

(7)安裝

(8)安裝完成

nagios+centreon監控構建

5.服務器端nrpe安裝

nrpe是nagios組件，能夠執行遠程主機的本地檢測腳本，監控運行狀態。

[root@localhost monitor]# tar -zxvf nrpe-2.14.tar.gz
[root@localhost nrpe-2.14]# ./configure
[root@localhost nrpe-2.14]# make all && make install

服務器端檢測錯誤

[root@nodes01 nrpe-2.12]# /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1
CHECK_NRPE: Error - Could not complete SSL handshake

在/usr/local/nagios/etc/nrpe.cfg加入

allowed_hosts=127.0.0.1,192.168.4.213

[root@nodes01 nrpe-2.12]# /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1
NRPE v2.12
[root@nodes01 nrpe-2.12]# /usr/local/nagios/libexec/check_nrpe -H 192.168.4.213
NRPE v2.12

三.后續登錄錯誤

1.錯誤信息

nagios+centreon監控構建

2.日志信息

25/4/2013 18:36:01 - 25/4/2013 18:36:1 - DBI connect('database=centreon_storage;host=localhost:3306','centreon',...) failed: Access denied for user 'centreon'@'localhost' to database 'centreon_storage' at /usr/local/centreon/bin/logAnalyser line 596

3.解決方法

mysql> grant all on centreon.* to centreon@localhost identified by '123456';
Query OK, 0 rows affected (0.07 sec)

mysql> grant all on centreon_status.* to centreon@localhost identified by '123456';
Query OK, 0 rows affected (0.00 sec)

mysql> grant all on centreon_storage.* to centreon@localhost identified by '123456';
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.06 sec)

成功頁面如下

nagios+centreon監控構建

四.檢查重新生成配置文件

(1)檢查main.cfg的配置

nagios+centreon監控構建

(2)檢查ndo2db.cfg的配置

nagios+centreon監控構建

(3)檢查ndomod.cfg的配置

nagios+centreon監控構建

(4)生成nagios配置文件

nagios+centreon監控構建

web頁面重啟完成后，查看nagios相關日志

[root@localhost ~]# tail -f /usr/local/nagios/var/nagios.log | grep ndomod
[1366898324] ndomod: Successfully connected to data sink. 122 queued items to flush.
[1366898324] ndomod: Successfully flushed 122 queued items to data sink.

如果有以上信息代表成功，因為ndoutils是nagios與centreon的紐帶，必須保證其正常運行。

centreon的服務器端已經配置完成，對于其被監控主機上也安裝nagios-plugins和nrpe軟件包，這里就不再重復，centreon的應用配置及漢化后續再出。
