原创 Linux操作系统 作者:mchdba 时间:2013-05-08 15:08:55 0 删除 编辑


-- ulimit -n 65535
-- 监控nagios客户端强行安装
1,安装
[root@localhost nagios]# ll
总计 768
-rw-r--r-- 1 root root 713389 12-16 12:08 nagios-plugins-1.4.11-1.x86_64.rpm
-rw-r--r-- 1 root root  32706 12-16 12:09 nrpe-2.12-1.x86_64.rpm
-rw-r--r-- 1 root root  18997 12-16 12:08 nrpe-plugin-2.12-1.x86_64.rpm

Shell> rpm -ivh *.rpm --nodeps  --force

 

2,检测
[root@rdb-s108 nagios]# /usr/lib64/nagios/plugins/check_mysql -unagios -P3306 -S -Hlocalhost -ppwdnagios -s/opt/mysql/product/mysql/mysql3306.sock -d test -w 60 -c 100

 

3,加进配置文件里面去
[root@rdb-s108 nagios]# vim /etc/nagios/nrpe.cfg

command[check_mysqlapi]=/usr/lib64/nagios/plugins/check_mysql -unagios -P3306 -S -Hlocalhost -ppwdnagios -s/opt/mysql/product/mysql/mysql3306.sock -d test -w 60 -c 100
加监控主机服务器ip地址
allowed_hosts = 127.0.0.1,192.168.188.110,10.80.98.2

-- 赋予权限
chmod 775 /usr/lib/nagios/plugins/check_mysql
-- 磁盘监控,查看
fdisk -l
Disk /dev/sda: 193.2 GB, 193273528320 bytes
255 heads, 63 sectors/track, 23497 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          13      104391   83  Linux
/dev/sda2              14       23497   188635230   8e  Linux LVM

取 Disk 后面的 /dev/sda 作为磁盘监控

 

4,重启nagios,失败

5,先删除再启动
[root@rdb-s108 bin]# killall nrpe 【】先删除
[root@rdb-s108 local]#  /usr/sbin/nrpe -c /etc/nagios/nrpe.cfg -d
[root@rdb-s108 local]#

 

6,vim "/etc/nagios/nrpe.cfg" 看情况
注释:# command[check_hda1]=/usr/lib/nagios/plugins/check_disk -w 20% -c 10% -p /dev/hda1
打开:#command[check_disk]=/usr/lib/nagios/plugins/check_disk -w $ARG1$ -c $ARG2$ -p $ARG3$

grant SUPER,REPLICATION CLIENT on *.* to nagios@'localhost' identified by 'pwdnagios';

7,检测状况 service nrpe status


8,检查
shell> vim /etc/nagios/nrpe.cfg
command[check_disk]=/usr/lib/nagios/plugins/check_disk -w 20% -c 10% -p /dev/sda
shell> fdisk -l
shell> service nrpe restart
