MySQL 服务器部署 Nagios 监控

— 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
