– 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 $ARG1$ARG1 -c $ARG2$ARG2 -p $ARG3$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
