在mysql服务器上部署nagios监控工具的具体方法
1，nagios安装
复制代码代码示例:
[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
复制代码代码示例:
[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
复制代码代码示例:
[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
复制代码代码示例:
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
复制代码代码示例:
[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
复制代码代码示例:
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
复制代码代码示例:
service nrpe status
8，检查
复制代码代码示例:
shell> vim /etc/nagios/nrpe.cfg
(责任编辑：IT)command[check_disk]=/usr/lib/nagios/plugins/check_disk -w 20% -c 10% -p /dev/sda shell> fdisk -l shell> service nrpe restart |
