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：
# 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

make
make install
tar xzvf DBD-mysql-3.0008.tar.gz

##############这里要说明下启动ndo2db那步骤我没做,修改了ndo2db.cfg,ndomod.cfg里面的相关socket type选项及数据库相关项,
之后直接service nagios restart,如果做的话出现错误提示请看下面解决办法###########
关于启动ndo出现错误提示：
1. 如果启动后出现错误：Could not bind socket: Address already in use
解决解决办法是将/usr/local/nagios/var/ndo.sock删除，停止ndo的时候这个文件不会被删除，可以自己写个启动脚本将这个文件删
除后在启动ndo。
2. 启动ndo后在日志中出现：nagios ndo2db-3x: Error: mysql_query() failed for 'INSERT INTO nagios_configfilevariables
SET instance_id='1', configfile_id='3', varname='cfg_file', varvalue='/usr/local/nagios//etc/objects/localhost\.cfg
解决办法是使用：mysql -uroot --password="canada" -h192.168.1.97 -e "alter table nagios.nagios_configfilevariables
drop key instance_id;alter table nagios.nagios_configfilevariables add index (instance_id, configfile_id, varname);
需要修改表结构。
关于出现mysql相关(DBD,perl)错误提示:
1. 如在make 阶段出错
(1)类、、、、make: *** [dbdimp.o] 错误 1
多半是库文件的问题，（--cflags=-I/usr/local/mysql/include/mysq 细查，少个“y"
（2）类 LD_RUN_PATH="/usr/lib/mysql:/lib:/usr/lib" gcc
-o blib/arch/auto/DBD/mysql/mysql.so -shared
-L/usr/local/lib dbdimp.o mysql.o -L/usr/lib/mysql
-lmysqlclient -lm -L/usr/lib/gcc-lib/i386-redhat-linux/2.96
-lgcc -lz
/usr/bin/ld: cannot find[b] -lz[/b]
collect2: ld returned 1 exit status
make: *** [blib/arch/auto/DBD/mysql/mysql.so] Error 1
与压缩包有关。可用 ldconfig -p | grep libz
ldconfig -p | grep libgz
查找，如有并指定路径！否则安装 libz-devel／ibgz-devel／zlib-devel／ gzlib-devel
2. 在make test 阶段出错:
(1)类: install_driver(mysql) failed: [b]Can't load[/b]
