将Nagios监控信息存入Mysql

qq489498494

　　一、NDOUtils安装需求：
　　nagios：安装方法：http://www.cnblogs.com/Richardzhu/p/3340638.html
　　mysql：源码安装方法：http://www.cnblogs.com/Richardzhu/p/3220883.html
　　DBI和DBD-mysql安装方法如下：



shell> perl -MCPAN -e shell
cpan> install DBI
cpan> install DBD::mysql
　　二、关联mysql头文件和库：
　　不做关联可能在config或make时出错



ln -s /app/mysql/include/* /usr/include/
ln -s /app/mysql/lib/* /usr/lib/
echo '/usr/lib' >> /etc/ld.so.conf
ldconfig -v
　　三、安装nodutils：



tar zxvf ndoutils-1.4b7.tar.gz
cd ndoutils-1.4b7
./configure --prefix=/usr/local/nagios --enable-mysql --disable-pgsql LDFLAGS=-L/app/mysql/lib --with-mysql-inc=/app/mysql/include/mysql --with-mysql-lib=/app/mysql/lib/mysql
make
　　四、拷贝文件：



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/*
　　五、拷贝配置文件：



cp ./config/ndo* /usr/local/nagios/etc/
chown nagios:nagios /usr/local/nagios/etc/*
　　六、创建ndo的mysql数据库及用户



CREATE DATABASE `nagios` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
GRANT select,insert,update,delete ON nagios.* TO nagios@localhost identified by 'nagios';
FLUSH PRIVILEGES ;
　　七、导入数据库结构



cd ./db/
./installdb -u root -p 123456 -h localhost -d nagios
　　如果这里root没有密码的话需要进行修改。
八、修改配置文件



vim /usr/local/nagios/etc/ndo2db.cfg
db_user=nagios
db_pass=nagios
socket_type=tcp
vim /usr/local/nagios/etc/nagios.cfg
broker_module=/usr/local/nagios/bin/ndomod-3x.o config_file=/usr/local/nagios/etc/ndomod.cfg
vim /usr/local/nagios/etc/ndomod.cfg
output_type=file
output=/usr/local/nagios/var/ndo.dat
　　九、启动ndo2db



/usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg
　　十、重启nagios



/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
service nagios restart
　　十一、检查安装是否正确
　　tail -f /usr/local/nagios/var/nagios.log
　　涉及的错误：
　　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。 alter table nagios.nagios_configfilevariables drop key instance_id; alter table nagios.nagios_configfilevariables add index (instance_id, configfile_id, varname);
　　tcp连接Mysql /usr/local/nagios/bin/file2sock -s /usr/local/nagios/var/ndo.dat -d localhost -t tcp -p 5668
