二、ndoutils 安装：

1、mysql安装（若未安装）

#apt-get install mysql-servermysql-client

2.DBI安装（若未安装）

#cd
/usr/local

# wgethttp://www.cpan.org/modules/by-module/DBI/DBI-1.625.tar.gz

#tar zxvf DBI-1.625.tar.gz

# cd DBI-1.625

# perl Makefile.PL

#make

# make test

# make install

3.DBD安装（若未安装）

#cd/usr/local

# wgethttp://www.cpan.org/modules/by-module/DBD/DBD-mysql-4.023.tar.gz

#tar -zxvf DBD-mysql-4.023.tar.gz

# cd DBD-mysql-4.023

# perlMakefile.PL

假设此时报错。找不到mysql_config，则先安装libmysqlclient-dev。输入以下这行命令：

# apt-get installlibmysqlclient-dev

之后再运行 #perl Makefile.PL


# make

# make install# perl Makefile.PL

4、NDOUtils安装

#cd /usr/local

#wgethttp://sourceforge.net/projects/nagios/files/ndoutils-1.x/ndoutils-1.4b7/ndoutils-1.4b7.tar.gz

# tarzxvf ndoutils-1.4b7.tar.gz

# cd ndoutils-1.4b7

#./configure--prefix=/usr/local/nagios --enable-mysql --disable-pgsqlLDFLAGS=-L/opt/mysql/lib --with-mysql-inc=/opt/mysql/include/mysql--with-mysql-lib=/opt/mysql/lib/mysql

# make

复制文件

1. cp./src/ndomod-3x.o /usr/local/nagios/bin
   

2. cp./src/ndo2db-3x /usr/local/nagios/bin
   

3. cp./src/log2ndo /usr/local/nagios/bin
   

4. cp./src/file2sock /usr/local/nagios/bin
   

5. chown nagios:nagios/usr/local/nagios/bin/*

拷贝配置文件

1. cp./config/ndo* /usr/local/nagios/etc/
   

2. chown nagios:nagios/usr/local/nagios/etc/*

5、为NDOUtils创建数据库

#mysql -u root -p

Enterpassword:
这里输入登录password：root。

mysql>create database nagios;

mysql> GRANTSELECT,INSERT,UPDATE,DELETE ON nagios.* TO nagios@localhostIDENTIFIED BY '123456';

mysql> flush privileges;

mysql>\q

生成ndoutils所须要的数据库

#cd db

# ./installdb -u root -p root -h localhost -d nagios

提示Done。登录mysql能够看到有59张表。：

#mysql -u root -p

Enterpassword
root

mysql>use nagios

Readingtable information for completion of table and column names

Youcan turn off this feature to get a quicker startup with -A

Databasechanged

mysql>show tables;

59rows in set (0.00 sec)
（安装正确）

6、编辑配置文件

选择，插入，更新。删除数nagios据库用户权限。

# vi/usr/local/nagios/etc/ndo2db.cfg

//安装完毕时提示的数据库的用户和用户组。#代表凝视。

ndo2db_user=nagios

ndo2db_group=nagios

#socket_type=unix

socket_type=tcp

db_user=root //
在前面的#./installdb -u root -p root -h localhost -d nagios中指定的

db_pass=root

# vi/usr/local/nagios/etc/nagios.cfg

#复制以下内容粘贴到#broker_module＝...以下。

# 注意broker_module=和config_file是在一行上

broker_module=/usr/local/nagios/bin/ndomod-3x.oconfig_file=/usr/local/nagios/etc/ndomod.cfg

此外。确保/usr/local/nagios/etc/nagios.cfg中有例如以下行出现。否则，请自行加入

event_broker_options=-1//为Nagios开启eventbroker

# vi/usr/local/nagios/etc/ndomod.cfg

#output_type=file

output_type=tcpsocket

#output_type=unixsocket

#output=/usr/local/nagios/var/ndo.dat

output=127.0.0.1

#output=/usr/local/nagios/var/ndo.sock

7、启动ndo2db

启动ndo2db

#/usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg

假设提示
couldnot bind socket: address already in use 则删除
ndo.sock：

rm/usr/local/nagios/var/ndo.sock

设置开机启动（）

vim/etc/rc.local

在 exit0
之前增加下面内容：

/usr/local/nagios/bin/ndo2db-3x-c /usr/local/nagios/etc/ndo2db.cfg

重新启动ndo2db 的方法：

psaux |grep ndo2db 找到该进程

nagios17539 0.0 0.0 10308 592 ?

Ss 15:52 0:00/usr/local/nagios/bin/ndo2db-3x -c/usr/local/nagios/etc/ndo2db.cfg

nagios 17585 0.6 0.2 19528 1560 ?S 15:52 0:17 /usr/local/nagios/bin/ndo2db-3x -c/usr/local/nagios/etc/ndo2db.cfg

nagios 17586 0.1 0.2 19528 1560 ?S 15:52 0:05 /usr/local/nagios/bin/ndo2db-3x -c/usr/local/nagios/etc/ndo2db.cfg

root 18436 0.0 0.1 4588 800 pts/3S+ 16:39 0:00 grep --color=auto ndo2db



kill pid 号如17539 和17585

8.重新启动动nagios

检查配置文件正确性

#/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

重新启动nagios

#service nagios restart

普通情况下到此已完毕安装，能够去数据库里看下记录有无添加

9、检查安装是否正确

#tail -20 /usr/local/nagios/var/nagios.log

[1227766166] ndomod: NDOMOD1.4b7 (10-31-2007) Copyright (c) 2005-2007 Ethan Galstad(nagios@nagios.org)

[1227766166] Finished daemonizing… (NewPID=18848)



表示正常。

假设有问题。解决之后，每次都要重新启动ndo2db和nagios。
