cacti安装成功了，下载一个npc插件来套用nagios，nagios要用ndoutils和cacti连接。

主要安装ndoutils出现的问题。

启动ndoutils时出错：

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

错误提示：

Support for the specified database server is either not yet supported, or was not found on your system

原因：mysql的库文件没有被加载，编译是时注意:

checking for linker flags for loadable modules... -shared
checking for mysql_config... /usr/bin/mysql_config
checking for mysql_init in -lmysqlclient... yes
MySQL library and include file(s) were found!
configure: creating ./config.status
config.status: creating Makefile
config.status: creating src/Makefile
config.status: creating docs/docbook/en-en/Makefile
config.status: creating subst
config.status: creating include/config.h
config.status: include/config.h is unchanged

以上蓝色部分是否都有。

解决方法：

yum安装的mysql

./configure --enable-mysql

编译安装的mysql

./configure --enable-mysql --with-mysql=/usr/local/mysql ### mysql 路径

把库文件做软连接

ln -s /usr/local/mysql/lib/* /usr/lib/

ln -s /usr/local/mysql/include/* /usr/include/

echo "/usr/lib" > /etc/ld.so.config

ldconfig -v

编译安装不是亲测的。

就可以启动了，

启动后还是不现实

查看日志：

tail -30 /var/log/message

错误：

nagios ndo2db-3x: Error: mysql_query() failed for 'INSERT INTO nagios_configfilevariablesSET instance_id='1', configfile_id='3', varname='cfg_file', varvalue='/usr/local/nagios//etc/objects/localhost\.cfg

解决方法：

登录mysql

输入以下信息：

alter table nagios.nagios_configfilevariablesdrop key instance_id;alter table nagios.nagios_configfilevariables add index (instance_id, configfile_id, varname);

重启naigos后还是不显示，

在看日志又出现：

localhost ndo2db-3x: mysql_error: 'Unknown column 'long_output' in 'fieldlist''
解决方法：

ALTER TABLE npc_eventhandlers ADD long_output TEXT NOT NULL DEFAULT '' AFTER output;
ALTER TABLE npc_hostchecks ADD long_output TEXT NOT NULL DEFAULT '' AFTER output;
ALTER TABLE npc_hoststatus ADD long_output TEXT NOT NULL DEFAULT '' AFTER output;
ALTER TABLE npc_notifications ADD long_output TEXT NOT NULL DEFAULT '' AFTER output;
ALTER TABLE npc_servicechecks ADD long_output TEXT NOT NULL DEFAULT '' AFTER output;
ALTER TABLE npc_servicestatus ADD long_output TEXT NOT NULL DEFAULT '' AFTER output;
ALTER TABLE npc_statehistory ADD long_output TEXT NOT NULL DEFAULT '' AFTERo utput;
ALTER TABLE npc_systemcommands ADD long_output TEXT NOT NULL DEFAULT '' AFTER output;

把以上内容写入naigos.sql

运行：

mysql -u root -p nagios < naigos.sql

输入密码：

再重启naigos。

终于出现了内容：

以上是个人整理。详细内容请看：
