nagios 安装和配置（含有nrpe结束）所有 （两）
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
[*] cp./src/ndomod-3x.o /usr/local/nagios/bin
[*] cp./src/ndo2db-3x /usr/local/nagios/bin
[*] cp./src/log2ndo /usr/local/nagios/bin
[*] cp./src/file2sock /usr/local/nagios/bin
[*] chown nagios:nagios/usr/local/nagios/bin/*
拷贝配置文件
[*] cp./config/ndo* /usr/local/nagios/etc/
[*] 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
ndomod: NDOMOD1.4b7 (10-31-2007) Copyright (c) 2005-2007 Ethan Galstad(nagios@nagios.org)
ndomod: Successfully connected to data sink. 0 queued items toflush.
Event broker module‘/usr/local/nagios/bin/ndomod-3x.o’ initializedsuccessfully.

表示正常。
假设有问题。解决之后，每次都要重新启动ndo2db和nagios。
