nagios+mysql+ndo2db安装与配置

 

1、首先需要安装ndoutils以将nagios的数据能导入到mysql数据库中。确认系统是否安装DBI和DBD-mysql。

#安装DBI-1.616.tar.gz

    tar xvzf DBI-1.616.tar.gz
    cd DBI-1.616
    perl Makefile.PL
    make
    make install

#安装DBD-mysql-4.018.tar.gz

    tar xvzf DBD-mysql-4.018.tar.gz
    cd DBD-mysql-4.018
    perl Makefile.PL --libs="-L/usr/local/mysql/lib/mysql -lmysqlclient -L/usr/lib -lz " --cflags=-I/usr/local/mysql/include/mysql --mysql_config=/usr/local/mysql/bin/mysql_config --testhost=127.0.0.1 --testsocket=/usr/local/mysql/tmp/mysql.sock --testdb=nagios --testuser=nagios --testpassword=15851678235
    make
    make install

#安装ndoutils

链接数据库
ln -s /usr/local/mysql/include/* /usr/include/mysql
ln -s /usr/local/mysql/lib/* /usr/lib/
ldconfig -v


tar xvzf ndoutils-1.4b7.tar.gz

cd ndoutils-1.4b7

./configure --enable-mysql

make

#复制文件到nagios目录，并设置属主。
cd src

cp ndomod-3x.o ndo2db-3x log2ndo file2sock /usr/local/nagios/bin

chown nagios:nagcmd /usr/local/nagios/bin/*

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

chown nagios:nagcmd /usr/local/nagios/etc/*

cd ../db

#创建数据库nagios,并导入数据库。
/usr/local/mysql/bin/mysql -uroot -p

create database nagios;

grant select,update,insert,delete on nagios.* to nagios@localhost identified BY '123456';

flush privileges;

use nagios;

source /root/nagios/ndoutils-1.4b7/db/mysql/mysql.sql;

vim /usr/local/nagios/etc/ndo2db.cfg

修改其中的
db_user=
db_pass=
db_name=
ndo2db_user=
ndo2db_group=
其余按实际情况修改

vim /usr/local/nagios/etc/nagios.cfg

#　复制下面内容粘贴到/usr/local/nagios/etc/nagios.cfg配置文件的#broker_module＝...下面。

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

#　修改/usr/local/nagios/etc/nagios.cfg配置文件下面参数的值为-1（一般默认如此）。

event_broker_options=-1

启动ndoutils

cp -rp ndo2db-3x ndo2db

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

出现错误：
1、/usr/local/nagios/bin/ndo2db: error while loading shared libraries: libmysqlclient.so.15: cannot open shared object file: No such file or directory
解决办法：cd /etc/ld.so.conf.d/
         touch mysql.conf
     vim mysql.conf输入：
     /usr/lib/mysql/
     保存退出
加载：ldconfig -v
重新运行OK。
2、查看nagios日志，发现：ndomod: Still unable to connect to data sink.  291071 items lost, 5000 queued items to flush.错误，看来还是有点小问题。

解决办法：重新启动ndo2db就可以了~，如果无法启动，删除ndo2db.sock，再重新启动。
