参考此文档 http://blog.csdn.net/xtdhqdhq/article/details/19197635(Nagios监控服务端与客户端的安装)
假设监控机:192.168.0.10 server1
被监控机:192.168.0.11 server2
此处简要的说明注意的几个点:
在server2上:
1、修改nrpe.cfg
监控主机的nagios是通过调用被监控机的nrpe来获取信息,那么我们先在被监控机的nrpe配置上添加要搜索的信息,也就是一些命令,然后nagios就通过nrpe调用这些命令来获取信息。这些命令是在nrpe.cfg文件中定义:
command[check_mysql_status]=/usr/local/nagios/libexec/check_mysql -H localhost -u nagios -p nagios -P 3306
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
3、测试下面命令是否能执行
/usr/local/nagios/libexec/check_mysql -H localhost -u nagios -p nagios -P 3306
在server1 上:
1、配置nagios监控主机的配置文件
/usr/local/nagios/etc/nagios.cfg
cfg_file=/usr/local/nagios/etc/objects/commands.cfg #nagios可调用的监控命令
cfg_file=/usr/local/nagios/etc/objects/contacts.cfg #联系人配置
cfg_file=/usr/local/nagios/etc/objects/timeperiods.cfg #监控时间配置
cfg_file=/usr/local/nagios/etc/objects/templates.cfg #模板配置
cfg_dir=/usr/local/nagios/etc/servers #新添加的目录,把需要添加的主机文件放进去,就不必在这里一行行添加
cfg_file=/usr/local/nagios/etc/objects/hostgroups.cfg #新添加,主机组配置
cfg_file=/usr/local/nagios/etc/objects/localhost.cfg #本地信息监迭
2、利用nrpe监控server2主机的本地信息
3、添加被监控机
创建server2的cfg文件在
/usr/local/nagios/etc/servers目录下,并修改其
cp /usr/local/nagios/etc/objects/localhost.cfg /usr/local/nagios/etc/servers/192.168.0.11.cfg
nano 192.168.0.11.cfg
# HOST DEFINITION # Define a host for the local machine define host{ use linux-server ; Name of host template to use ; This host definition will inherit all variables that are defined ; in (or inherited by) the linux-server host template definition. host_name 192.168.0.11 alias linux-server 11 address 192.168.0.11 } define service{ use local-service ; Name of service template to use host_name 192.168.0.11 service_description MySQL check_command check_nrpe!check_mysql_status # notifications_enabled 0 }
4、创建hostgroups.cfg
注释掉localhost 中的hostgroup ,在此文件中同意定义
nano hostgroups.cfg
###############################################################################
###############################################################################
# HOST GROUP DEFINITION
###############################################################################
###############################################################################
# Define an optional hostgroup for Linux machines
define hostgroup{
hostgroup_name linux-servers ; The name of the hostgroup
alias Linux Servers ; Long name of the group
members localhost ; Comma separated list of hosts that belong to this group
}
define hostgroup{
hostgroup_name linux-servers-jk ; The name of the hostgroup
alias Linux Servers Jk ; Long name of the group
members 192.168.0.11 ; Comma separated list of hosts that belong to this group
}
5、重启nagios
service nagios reload
