Cacti Monitoring Server configuration tutorial (based on centos+nginx+mysql+php Environment building)

Install centos web panel
Specific cases:
LAN has two hosts, a Linux, a Windows, now need to configure a cacti monitoring server to monitor the two hosts
Environment Description:
1. Linux Host
Operating system: CentOS 6.2
IP Address: 192.168.21.164
Subnet Mask: 255.255.255.0
Gateway: 192.168.21.2
dns:8.8.8.8 8.8.4.4

Centos web panel
2. Windows host
Operating system: Windows Server 2003
IP Address: 192.168.21.130
Subnet Mask: 255.255.255.0
Gateway: 192.168.21.2
dns:8.8.8.8 8.8.4.4

Install centos web panel on centos 7
3, need to configure the Cacti monitoring server
Operating system: CentOS 6.2
IP Address: 192.168.21.169
Subnet Mask: 255.255.255.0
Gateway: 192.168.21.2
dns:8.8.8.8 8.8.4.4
Tutorial Start:
First, install the configuration Cacti monitoring Server
1. Installation system: Please refer to
CentOS 6.2 Installation (Super detailed illustrated tutorial): http://www.osyunwei.com/archives/1537.html
2, set the IP address, gateway, DNS: please refer to
CentOS 6.0 Set IP address, gateway, dns:http://www.osyunwei.com/archives/423.html
Note: The CentOS 6.2 IP address, gateway, DNS settings are identical to CentOS 6.0

Virtualmin vs centos web panel
3, configure the firewall, start 80 ports, 3306 ports, 161 ports
Vi/etc/sysconfig/iptables
-A input-m state--state new-m tcp-p TCP--dport 80-j ACCEPT
-A input-m state--state new-m tcp-p TCP--dport 3306-j ACCEPT
-A input-m state--state new-m udp-p UDP--dport 161-j ACCEPT
Special Note: Many netizens add these two rules to the last line of the firewall configuration, causing the firewall to fail to start, the correct one should be added to the default 22 port under this rule
After adding the firewall rules as follows: centos web panel tutorial

Click Next and the following screen appears

Each option below is [Ok:file FOUND], which indicates that the configuration file path is all correct
Click Finish, the login screen appears

At this point, the Cacti Monitoring Server installation is complete
Second, configure the monitored host
1. Configuring Windows Host
Description: To monitor a Windows host using cacti, SNMP (Simple Network Management Protocol) needs to be installed on the monitored host

The following installation configures SNMP

Start-Settings-Control Panel-Add or Remove Programs-add remove Windows Components

Find the management and monitoring tools, tick the front, tick in the point details: Simple Network Management Protocol (SNMP), then OK, next

System operation and maintenance www.osyunwei.com warm reminder: qihang01 original content copyright, reproduced please indicate the source and the original link

Start the installation until the installation is complete (note: You will be prompted to insert the Windows system CD during the installation process, which needs to be prepared in advance.) )

Start-run, enter services.msc OK, open service management

Locate the SNMP Service option, double-click Open, switch to security options, click Add under Accept community name, and the SNMP services configuration appears

Group permissions: Read-only

Group Name: Public

Finally determined

Check: Accept SNMP packets from these hosts, add the following points, enter the IP address of the cacti monitoring host in the hostname, IP, or IPX addresses

Enter here: 192.168.21.169, finally, apply, OK.

Finally, restart the Windows system, and the monitored Windows Host settings are complete.
2. Configure the Linux host

Note: To use cacti to monitor a Linux host, you need to install NET-SNMP and other related packages on the monitored host;

Also need to open firewall UDP161 port

(1), open firewall UDP161 port

Vi/etc/sysconfig/iptables #编辑防火墙配置

-A input-m state--state new-m udp-p UDP--dport 161-j ACCEPT

/etc/init.d/iptables Restart #重启防火墙使配置生效

(2), install NET-SNMP (here the Yum command using CentOS is installed online)

Yum-y Install NET-SNMP

Chkconfig snmpd on #设置开机启动

Service SNMPD Start #启动snmpd

(2), configuring SNMP

Cp/etc/snmp/snmpd.conf/etc/snmp/snmpd.confbak #备份配置文件

Vi/etc/snmp/snmpd.conf #编辑, modify to the following content

1	com2sec notConfigUser  192.168.21.169       public

2	access  notConfigGroup ""any       noauth    exact  all  none none

3	view all    included  .1                               80

Netstat-nlup |grep ": 161" #检查snmp服务器是否运行, a similar output appears, indicating that SNMP is operating properly

UDP 0 0 0.0.0.0:161 0.0.0.0:* 2765/snmpd

At this point, the monitored Linux host settings are complete.
Iii. setting up the Cacti Monitoring server to monitor Windows and Linux hosts

1. Adding monitoring to Windows hosts

Management-devices, click Add in the upper-right corner, adding the host

The relevant options are described in detail:

Description: Description

Hostname: Host name, IP address of the host to monitor, here is 192.168.21.130

Host Template: Hosting templates, selecting Windows 2000/xp Host

Monitor host: The back tick indicates enable

SNMP COMMUNITY:SNMP community Name, be sure to be the same as the SNMP community name set before Windows host, otherwise the monitoring fails, this is public

SNMP PORT:SNMP Port, default is 161

Other options default to

Finally, click Save and the following interface will appear

Click Create Graphs for this host: Add graphics to this console, select the check box on the right for the object you want to monitor,

Click Create To add

Note that the last item, select a graphics type, 32-bit host select In/out Bytes; 64-bit host select In/out Bytes (64-bit)

The following interface appears, and then click Add

Click on the graphs Monitor in the navigation bar above to enter the monitoring interface,

Select the host we just added, you can already see the graph of monitoring, but this time there is no data, data acquisition is 5 minutes polling

Wait a few minutes, refresh, you will see the following interface, this time the monitoring data has been.

Windows Host monitoring Settings complete

2. Adding monitoring to Linux hosts

Add the same method as Windows

Note: Hostname: Host name fill in Linux host ip,host template host templates select Local Linux machine

System operation and maintenance www.osyunwei.com warm reminder: qihang01 original content copyright, reproduced please indicate the source and the original link

Add the last point, and then click Create Graphs for this host to add graphics to the

Select the right check box for the object you want to monitor, click Add

The following interface appears, then click Create To add

Then click on the Graphs Monitor in the navigation bar above, go to the Monitoring screen, select the Linux host you just added,

Also wait a few minutes, you will see the following monitoring data

Linux Host Monitoring Setup Complete
