NDOUtils将Nagios监控信息存入MySQL

admin · 发表于 2018-6-25 00:11:37

使用NDOUtils将Nagios监控信息存入MySQL
1.NDOUtils安装需求
nagios
mysql
cpan DBI #非必需
cpan DBD::mysql #非必需
2.关联mysql头文件和库
不做关联可能在config或make时出错
ln -s /opt/mysql/include/* /usr/include/
ln -s /opt/mysql/lib/* /usr/lib/
echo ‘/usr/lib’ >> /etc/ld.so.conf
ldconfig -v
3.安装ndoutils
http://sourceforge.net/project/showfiles.php?group_id=26589
wget -c http://nchc.dl.sourceforge.net/s ... outils-1.4b7.tar.gz
tar zxvf ndoutils-1.4b7.tar.gz
cd ndoutils-1.4b7
./configure –prefix=/usr/local/nagios –enable-mysql –disable-pgsql LDFLAGS=-L/opt/mysql/lib –with-mysql-inc=/opt/mysql/include/mysql –with-mysql-lib=/opt/mysql/lib/mysql
*config时使用以下mysql参数
–with-mysql-inc=/opt/mysql/include –with-mysql-lib=/opt/mysql/lib
#config成功
#make出错
*config时使用以下mysql参数
–with-mysql-inc=/opt/mysql/include/mysql –with-mysql-lib=/opt/mysql/lib/mysql
#config出错
#make成功并生成文件
#启动ndo2db会出错
*没有LDFLAGS=-L/opt/mysql/lib
<del datetime="2009-05-27T06:58:24+00:00">LDFLAGS=-L/opt/mysql/lib </del>
#ndo2db不能导入到数据库
相关错误
In file included from io.c:10:
../include/config.h:261:25: mysql/mysql.h: 没有那个文件或目录
../include/config.h:262:26: mysql/errmsg.h: 没有那个文件或目录
make[1]: *** [io.o] 错误 1
checking for mysql/mysql.h… no

*** MySQL include file could not be located… **********************

You chose to compile NDBXT with MySQL support, but I was unable to
locate on your system. If the include file is
installed, use the –with-mysql-inc argument to specify the location
of the MySQL include file.
make
ll ./src
看看是否有以下文件
ndo2db-2x
ndo2db-3x
ndomod-2x.o
ndomod-3x.o
4.拷贝文件
# 我的Nagios是3.0.6,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
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/*
5.拷贝配置文件
cp ./config/ndo* /usr/local/nagios/etc/
chown nagios:nagios /usr/local/nagios/etc/*
6.创建ndo的mysql 数据库及用户
CREATEDATABASE`nagios`DEFAULTCHARACTERSETutf8COLLATEutf8_general_ci;
GRANT select,insert,update,deleteONnagios.*TOnagiosndo@localhostidentifiedby’password123′;
FLUSH PRIVILEGES;
7.导入数据库结构
使用db/installdb脚本
需要以下支持
cpan DBIcpan DBD::mysql
cd ./db/
./installdb -u root -p 123456 -h localhost -d nagios
用命令导入(其实和用脚本是一回事,也可以用phpmyadmin来导入)
/opt/mysql/bin/mysql -u root -p -D nagios -h localhost < ./db/mysql.sql
输入密码
成功导入59张表
8.修改配置文件
vi /usr/local/nagios/etc/ndo2db.cfg
db_user=nagiosndo
db_pass=password123
vi /usr/local/nagios/etc/nagios.cfg
# 修改下面参数的值为-1(一般默认如此)。
event_broker_options=-1
# 复制下面内容粘贴到#broker_module=…下面。
# 注意broker_module= 和config_file是在一行上
# Uncomment the line below if you’re running Nagios 3.x
broker_module=/usr/local/nagios/bin/ndomod-3x.o config_file=/usr/local/nagios/etc/ndomod.cfg
9.启动ndo2db
/usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg

echo ‘rm -f /usr/local/nagios/var/ndo.sock’ >> /etc/rc.local
echo ‘/usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg’ >> /etc/rc.local
#开机启动
Support for the specified database server is either not yet supported, or was not found on your system.
/usr/local/nagios/bin/ndo2db-3x: error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: No such file or directory
出现以上错误请执行第2步
10.重启动nagios
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
service nagios restart
一般情况下到此已完成安装,可以去数据库里看下记录有无增加
11.检查安装是否正确
tail -20 /usr/local/nagios/var/nagios.log
[1242971625] ndomod: Successfully flushed 80 queued items to data sink.[1242971625] ndomod: Error writing to data sink! Some output may get lost…
貌似有点问题
先改成输出成文件#vi ndomod.cfg
instance_name=default
#output_type=tcpsocket
#output=127.0.0.1

output_type=file
output=/usr/local/nagios/var/ndo.dat
service nagios restart
看看有没有/usr/local/nagios/var/ndo.dat文件,ok,发现文件,说明第一步可以生成文件查看文件内容
cd /usr/local/nagios/var/
head -30 ndo.dat

HELLO
PROTOCOL: 2
AGENT: NDOMOD
AGENTVERSION: 1.4b7
STARTTIME: 1243393299
DISPOSITION: REALTIME
CONNECTION: FILE
CONNECTTYPE: INITIAL
INSTANCENAME: default
STARTDATADUMP

202:
1=300

74=262144
72=ndomod: Error writing to data sink!  Some output may get lost…
999

201:
1=205
2=0
使用file2sock尝试socket方式
../bin/file2sock -s /usr/local/nagios/var/ndo.dat -d /usr/local/nagios/var/ndo.sock -t unix -p 5668
Error while writing to destination socket: Connection reset by peer
尝试tcp方式
vi ndo2db.cfg
#socket_type=unix
socket_type=tcp
重新载入ndo2db
ps aux|grep ndo2db
kill $pid
/usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg

../bin/file2sock -s ndo.dat -d localhost -t tcp -p 5668
Error while writing to destination socket: Connection reset by peer
依然不行,重新编译ndoutils并加上 LDFLAGS=-L/opt/mysql/lib
./configure –prefix=/usr/local/nagios –enable-mysql –disable-pgsql LDFLAGS=-L/opt/mysql/lib –with-mysql-inc=/opt/mysql/include/mysql –with-mysql-lib=/opt/mysql/lib/mysql
make
#再执行一下安装过程后,通过
=================200912-07 更新
tail /var/log/messages

1.DBI的安装
# wget http://www.cpan.org/modules/by-module/DBI/DBI-1.608.tar.gz
# tar zxvf DBI-1.608.tar.gz
# cd DBI-1.608
# perl Makefile.PL
# make
# make test
# make install
2.DBD的安装
# wget http://www.cpan.org/modules/by-module/DBD/DBD-mysql-4.011.tar.gz
# tar -zxvf DBD-mysql-4.011.tar.gz
# cd DBD-mysql-4.011
# perl Makefile.PL --mysql_config=/usr/local/mysql/bin/mysql_config --libs=-L/usr/local/mysql/lib-static -lmysqlclient
# make
# make install

3.关联mysql头文件和库
# ln -s /usr/local/mysql/lib/mysql/* /usr/lib
# ln -s /usr/local/mysql/include/mysql/* /usr/include
# ldconfig -v

4.编译安装NDOUtils
# tar zxf ndoutils-1.4b9.tar.gz
# cd ndoutils-1.4b9
# ./configure --prefix=/usr/local/nagios --enable-mysql --disable-pgsql LDFLAGS=-L/usr/local/mysql/lib --with-mysql-inc=/usr/local/mysql/include/mysql --with-mysql-lib=/usr/local/mysql/lib/mysql

# 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/*

# cp ./config/ndo* /usr/local/nagios/etc/
# chown nagios:nagios /usr/local/nagios/etc/*

5.为NDOUtils创建数据库
# mysql -uroot -p
mysql> create database ndodb;
mysql>grant all on ndodb.* to 'ndouser'@'%' identified by '123456';
mysql> flush privileges;
mysql> /q
生成ndoutils所需要的数据库
# cd db
# ./installdb -u n root -p 123456 -h localhost -d ndodb
也可这样：# /opt/mysql/bin/mysql -u root -p -D nagios -h localhost < ./db/mysql.sql

6.编辑配置文件
# vi /usr/local/nagios/etc/ndo2db.cfg
db_user=nagios
db_pass=123456
# vi /usr/local/nagios/etc/nagios.cfg
# 复制下面内容粘贴到#broker_module＝...下面。
broker_module=/usr/local/nagios/bin/ndomod-3x.o config_file=/usr/local/nagios/etc/ndomod.cfg
此外，请确保您的/usr/local/nagios/etc/nagios.cfg中有如下行出现，否则，请自行添加：
event_broker_options=-1 //为Nagios开启event broker

7启动ndo2db
# /usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg
# echo '/usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg' >> /etc/rc.local

8.重启动nagios
# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
# service nagios restart
检查安装
tail -20 /usr/local/nagios/var/nagios.log

遇到问题：
1.执行 # /usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg
提示错误：Could not bind socket: Address already in use
解决：ps aux|grep ndo2db #没有
查看套接字文件是否存在,删除之
ll /usr/local/nagios/var/ndo.sock
rm /usr/local/nagios/var/ndo.sock
2.#ndo2db数据不能导入到数据库
原因:编译时没有LDFLAGS=-L/opt/mysql/lib
解决:重新编译ndoutils并加上 LDFLAGS=-L/opt/mysql/lib
# ./configure --prefix=/usr/local/nagios --enable-mysql --disable-pgsql LDFLAGS=-L/usr/local/mysql/lib --with-mysql-inc=/usr/local/mysql/include/mysql --with-mysql-lib=/usr/local/mysql/lib/mysql
# make
#再执行一下安装过程后，通过

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

##############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

-lgcc -lz
/usr/bin/ld: cannot find -lz
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: Can't load
