1.NDOUtils安装需求：
Nagios正确安装运行，版本>=2.0安装目录：/usr/local/nagios
MySQL正确安装并运行，我用的是二进制安装包，安装目录：/usr/local/mysql
2.安装
下载安装包：http://www.nagios.org/download/
# 确认DBD-mysql包安装，如没有安装，请先安装。
# 如果DBI包没安装DBD-mysql前需要先安装DBI包
tar xzvf DBI-1.605.tar.gz
cd DBI-1.605
perl Makefile.PL
make
make install
tar xzvf DBD-mysql-3.0008.tar.gz
cd DBD-mysql-3.0008

# 做好MySQL库文件lib和include文件的连接（这点很重要）。

tar xzvf ndoutils-1.4b7.tar.gz
cd ndoutils-1.4b7

# 我的Nagios是3.0.5，所以拷贝的是ndomod-3x.o、ndo2db-3x，如果你的是2.X.x请拷贝ndomod-2x.o、ndo2db-2x

cd ../db
# 创建数据库，使用root用户，密码是baihe.com

# 拷贝配置文件

# 启动ndo2db

3.如何用NDOUtils将多个Nagios实例的性能数据写入一个数据库？
配置方法类似于上面的单实例单数据库模式，只是在装第二个实例时省去安装DB一步，并需要修改/usr/local/nagios/etc/ndomod.cfg中的实例名。
实例名默认为instance_name=default，如果有多个实例必需修改成不同的实例名。
如：instance_name=nagios1
注意修改/usr/local/nagios/etc/ndo2db.cfg中数据库连接的相关配置。

=====
启动ndo2db
/usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg
========================
对于不同Nagios版本，NDOUtils有不同的启动程序，ndo2db-2x对应Nagios的2.X版本，ndo2db-3x对应Nagios的3.X版本，
我安装时Nagios3.0.3版，所以选用ndo2db-3x。
# cd /usr/local/nagios/bin
# ./ndo2db-3x -c ../etc/ndo2db.cfg
运行上述命令启动NDOUtils，查看后台日志看是否有问题。
注意，如果要停止ndo2db-3x进程，再使用kill命令杀掉对应的进程号后，还必须删除
/usr/local/nagios/var下的ndo.sock，
否则下次NDOUtils不能正常启动。
- Download the NDOUtils
wget http://prdownloads.sourceforge.net/sourceforge/nagios/ndoutils-1.4b8.tar.gz
- Install MySQL lib
yum install mysql-devel
- Compile
tar zxvf ndoutils-1.4b8.tar.gz -C /tmp cd /tmp/ndoutils-1.4b8 ./configure --with-mysql-libs=/usr/lib/mysql make
- Probably need to remove "mysql" in the include line of a certain source file, in case make reports error.
- Install
cd src cp ndomod-3x.o ndo2db-3x log2ndo file2sock /usr/local/nagios/bin/
- Create database
GRANT ALL PRIVILEGES ON nagios.* TO 'nagios'@'localhost' identified by "123456";
- Initialize database
cd ../db ./installdb -u nagios -p 123456s -h localhost -d nagios
- Configure NDO
cd ../config # copy the lines related NDO3.x in nagios.cfg to /usr/local/nagios/etc cp ndo2db.cfg ndomod.cfg /usr/local/nagios/etc # Modify /usr/local/nagios/etc/ndo2db.cfg, change the database connection info
- Start the service
/usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg /etc/init.d/nagios reload
