}（只留一个servergroup）
/usr/local/nagios/bin/nagios-v /usr/local/nagios/etc/nagios.cfg检查语法错误
/etc/init.d/nagios restart
用nagios监控另外一台主机上的mysql
Server27 上yum install mysql-server
/etc/init.d/mysqld restart

Cd/usr/local/nagios/etc/objects/
Vi commands.cfg 更改如下：
#’check_mysql’command definition
Define command{

/usr/local/nagios/bin/nagios-v/usr/local/nagios/etc/nagios.cfg检查语法错误
/etc/init.d/nagiosreload
Vi contacts.cfg 设置监控的内容出现错误时email通知的地址
Definecontact{
Contact_name nagiosadmin
Use generic-contact
Alias NagiosAdmin
Email yakexi007@westos.org
}
/etc/init.d/nagios reload
nagios安装好后，网页访问出现如下错误：
无权查看任何主机的信息。
请检查HTTP服务器关于该CGI的访问权限设置。
解决办法：
vi /usr/local/nagios/etc/cgi.cfg
将use_authentication的值改为0.
use_authentication=0
然后重启nagios服务
service nagios restart
还有可能：
配置文件中的hostname和service_description使用了中文。
建议hostname和service_description 不要使用中文

Mailyakexi007@westos.org发送测试邮件
在/usr/locl/nagios/var/ 查看nagios的日志nagios.log
用nagios监控其他主机的磁盘，用户，根分区等要在所要监控的织机上安装nagios的插件

Vi /etc/xinetd.d/nrpe更改如下：
吧only-from =192.168.0.196 改成这样
Vi/etc/services 更改如下:
nrpe 5666/tcp添加这一行让xinetd接听nrpe的端口
/etc/init.d/xinetd start
Netstat-natple|grep5666
Cd/usr/local/nagios/etc/
Vim nrpe.cfg 更改如下：
更改这行如command=/usr/local/nagios/libexec/check_disk-w 20%-c10% -p/
/etc/init.d/xinetd restart
在server96上也安装nrpe
Tarzxf nrpe-2.14.tar.gz
Cd nrpe-2.14
./configure
Make all
Makeinstall-plugin
Cd/usr/local/nagios/libexec/
./check_nrpe -H 192.168.0.127
如果出现NRPEV2.14则配置成功
./check_nrpe-H 192.168.0.127 -c check_disk
./check_nrpe -H 192.168.0.127-ccheck_users
Cd /usr/local/nagios/etc/objects/
Vi commands.cfg添加
Definecommand{
Command_name check_nrpe
Command_line $USER1$/check_nrpe-H $HOSTADDRESS$-c$ARG1$
}
Viservices.cfg添加
Define servicegroup{
Servicegroup_name 系统负荷检查
Alias 系统负荷
Members server96.example.com,进程总数,server96.example.com,登录用户数,server96.example.com,交换空间利用率,server27.example.com,根分区,server27.example.com,登录用户数,server27.example.com,系统负荷
}
Defineservice{
Use local-service
Host_name server27.example.com
Service_description更分区
Check_command check_nrpe!check_disk
}
Define service{
Use local-service
Host_name server27.example.com
Service_description 登录用户数
Check_command check_nrpe!check_users
}
Defineservice{
Use local-service
Host_name server27.example.com
Service_description 系统负荷
Check_command check_nrpe!check_load
}
/usr/local/nagios/bin/nagios-v /usr/locals/nagios/etc/nagios.cfg
/etc/init.d/nagios reload 这样就可以在图形中监控另外一台主机的根分区，登录用户等信息了。
