读取nagios数据库至MySQL

读取NAGIOS数据库至MYSQL

1.DBI的安装
wget http://www.cpan.org/modules/by-module/DBI/DBI-1.625.tar.gz tar xf DBI-1.625.tar.gz
cd DBI-1.625
yum -y install perl-ExtUtils-CBuilder perl-ExtUtils-MakeMaker
perl Makefile.PL
make
make install

2.DBD的安装
wget http://www.cpan.org/modules/by-module/DBD/DBD-mysql-4.023.tar.gz tar xf DBD-mysql-4.023.tar.gz
cd DBD-mysql-4.023
yum -y install mysql mysql-server mysql-devel
/etc/init.d/mysqld start
perl Makefile.PL --testhost=127.0.0.1 --testuser=root --testpassword=123456
make
make install

3.编译安装NDOUtils
wget http://jaist.dl.sourceforge.net/project/nagios/ndoutils-2.x/ndoutils-2.0.0/ndoutils-2.0.0.tar.gz tar xf ndoutils-2.0.0.tar.gz
cd ndoutils-2.0.0
./configure --enable-mysql --disable-pgsql --with-mysql-lib=/usr/lib64/mysql/
make

4.为NDOUtils创建数据库
建立Nagios数据库
Mysql 连接数据库
Create database nagios; 创建Nagios数据库
Grant all on nagios.* to nagios@localhost identified by “nagios”； 授权nagios用户，密码为 Nagios

初始化数据库
cd ndoutils-2.0.0
cd db
mysqladmin -u root password 123456
./installdb -u root -p 123456 -d nagios

5.安装nagios，此处是使用yum安装的。

cp config/ndo2db.cfg-sample /etc/nagios/ndo2db.cfg
cp config/ndomod.cfg-sample /etc/nagios/ndomod.cfg

cp ./src/ndomod-3x.o /usr/sbin/
cp ./src/ndo2db-3x /usr/sbin/
cp ./src/ndo2db‐3x /usr/sbin/ndo2db
cp ./src/log2ndo /usr/sbin/
cp ./src/file2sock /usr/sbin/

chown nagios. /etc/nagios/ -R
chmod 774 /usr/sbin/ndo*
chown nagios. /usr/sbin/ndo*

修改nagios主配置文件
#vim /etc/nagios/nagios.cfg 添加以下内容
check_external_commands=1

mkdir /usr/local/nagios/var/ -p
chown nagios /usr/local/nagios/var/
/usr/sbin/ndo2db -c /etc/nagios/ndo2db.cfg
或者
/usr/sbin/ndo2db-3x -c /etc/nagios/ndo2db.cfg

/etc/init.d/nagios restart
tail -f /var/log/messages
tail -f /var/log/nagios/nagios.log

若有mysql_query() 不能插入的错误，即Id问题。
解决问题：mysql> ALTER TABLE ‘nagios_configfilevariables’ DROP INDEX ‘instance_id’ ,
-> ADD INDEX ‘instance_id’ ( ‘instance_id’ , ‘configfile_id’ );
