三、实验目的：
四、实验过程：
[root@node2 /]# tar xvf DBI-1.609.tar.gz -C /usr/src
[root@node2 /]# cd /usr/src/DBI-1.609/
[root@node2 DBI-1.609]# perl Makefile.PL
[root@node2 DBI-1.609]#make && make install
[root@node2 /]# tar xvf DBD-mysql-4.014.tar.gz -C /usr/src
[root@node2 src]# cd DBD-mysql-4.014/
[root@node2 DBD-mysql-4.014]# perl Makefile.PL –mysql_config=/usr/local/mysql/bin –with-mysql=/usr/local/mysql
[root@node2 DBD-mysql-4.014]# make && make install
3.Ndoutils安装：
[root@node3 mysql]# ln -s /usr/local/mysql/include/* /usr/include/
[root@node3 mysql]# ln -s /usr/local/mysql/lib/* /usr/lib
[root@node3 /]#cd /usr/src/ndoutils-1.4b9/
[root@node3 src]# ./configure –prefix=/usr/local/nagios –enable-mysql –disable-pgsql LDFLAGS=-L/usr/local/mysql/lib/mysql –with-mysql-lib=/usr/local/mysql/lib/mysql –with-mysql=/usr/local/mysql
[root@node3 src]#make
[root@node3 src]# cd /usr/src/ndoutils-1.4b9/src/
[root@node3 src]# cp ndo2db-3x ndo2db-2x file2sock log2ndo /usr/local/nagios/bin/
[root@node3 config]# cp ndo2db.cfg-sample /usr/local/nagios/etc/ndo2db.cfg
[root@node3 config]# cp ndomod.cfg-sample /usr/local/nagios/etc/ndomod.cfg
[root@node3 bin]# mysql5

[root@node3 ndoutils-1.4b9]# cd db
[root@node3 db]# ./installdb -u ndouser -p ndouser -h localhost -d ndodb

添加以下两句，第二句如果没有才加上去，默认是有的。
[root@node3 etc]# /usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg
和属于我们的风景。一起吃早餐，
