CentOS 6.4 x64 Cacti 监控安装配置

Cacti 监控安装配置

 

环境：

 

安装Cacti 的服务器

 

Linux 6.4 x64

 

ip 10.8.8.11

 

 

一： 配置iptables , selinux

 

 

vi /etc/sysconfig/iptables

 

-------------------------------------------------------------------------

 

# Firewall configuration written by system-config-firewall

# Manual customization of this file is not recommended.

*filter

:INPUT ACCEPT [0:0]

:FORWARD ACCEPT [0:0]

:OUTPUT ACCEPT [0:0]

-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

-A INPUT -p icmp -j ACCEPT

-A INPUT -i lo -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT

-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 tcp -p tcp --dport 161 -j ACCEPT

-A INPUT -j REJECT --reject-with icmp-host-prohibited

-A FORWARD -j REJECT --reject-with icmp-host-prohibited

COMMIT

 

--------------------------------------------------------------------------

 

 

vi /etc/selinux/config

 

--------------------------------------------------------------------------

 

# This file controls the state of SELinux on the system.

# SELINUX= can take one of these three values:

#     enforcing - SELinux security policy is enforced.

#     permissive - SELinux prints warnings instead of enforcing.

#     disabled - No SELinux policy is loaded.

SELINUX=disabled

# SELINUXTYPE= can take one of these two values:

#     targeted - Targeted processes are protected,

#     mls - Multi Level Security protection.

SELINUXTYPE=targeted

 

--------------------------------------------------------------------------

 

 

 

reboot   重启服务器

 

 

 

二：安装配置WEB环境

 

lnmp 一键安装...省略....

 

 

 

 

 

三：安装配置Cacti Web服务

 

安装rrdtool、net-snmp以及相关依赖包

 

rrdtool  下载  :  http://oss.oetiker.ch/rrdtool/

 

 

yum install rrdtool net-snmp rrdtool-devel net-snmp-devel net-snmp-utils net-snmp-python net-snmp-perl lm_sensors-devel 

 

file-devel rpm-devel file intltool libart_lgpl libart_lgpl-devel elfutils pango-devel* cairo-devel* mysql-devel 

 

Mod_auth_mysql php-mysql cairo dejavu-fonts-common.noarch dejavu-lgc-sans-mono-fonts.noarch dejavu-sans-mono-

 

fonts.noarch fontpackages-filesystem.noarch libXft libXrender libthai pango pixman perl-rrdtool net-snmp net-snmp-utils 

 

tcp_wrappers-devel

 

 

chkconfig snmpd on  设置snmpd 开机启动

 

service snmpd start  启动snmpd服务

 

 

1. 下载Cactic 0.8.8a

 

wget http://www.cacti.net/downloads/cacti-0.8.8a.tar.gz

 

tar zxvf cacti-0.8.8a.tar.gz

 

cd cacti-0.8.8a

 

mkdir -p /opt/htdocs/cacti

 

cp -r * /opt/htdocs/cacti

 

chown upload:upload /opt/htdocs/cacti -R

 

chmod 700 /opt/htdocs/cacti -R

 

 

2. 设置Cacti 数据库

 

登陆mysql 

/opt/local/mysql/bin/mysql -uroot -p123456

 

创建数据库

create database cactidb;

 

创建数据库用户

insert into mysql.user(Host,User,Password) values('localhost','cactiuser',password('123456'));

 

授权用户cactiuser对数据库cactidb完全访问

grant all on cactidb.* to 'cactiuser'@'%' identified by '123456' with grant option;

 

设置生效

flush privileges;

 

use cactidb

 

导入cacti数据库文件

source /opt/htdocs/cacti/cacti.sql

 

exit

 

 

 

3. 配置Cacti 文件

 

vi /opt/htdocs/cacti/include/config.php

 

-----------------------------------------------------------------------------------------

 

*/

 

/* make sure these values refect your actual database/host/user/password */

$database_type = "mysql";

$database_default = "cactidb";

$database_hostname = "localhost";

$database_username = "cactiuser";

$database_password = "123456";

$database_port = "3306";

$database_ssl = false;

 

/*

   Edit this to point to the default URL of your Cacti install

   ex: if your cacti install as at http://serverip/cacti/ this

   would be set to /cacti/

*/

//$url_path = "/cacti/";

 

/* Default session name - Session name must contain alpha characters */

//$cacti_session_name = "Cacti";

 

?>

 

---------------------------------------------------------------------------------------------

 

 

 

配置完成以后.在浏览器输入 10.8.8.11

 

 

 

 

 

Please select the type of installation

选择New install

点Next，出现下面界面

 

 

 

登陆. 用户名密码都为 admin

 

如上提示，第一次登陆以后，会提示修改密码

 

 

 

设置定时采集

 

crontab -e

 

每5分钟采集一次

 

*/5 * * * * php   /opt/htdocs/cacti/poller.php

 

 

 

四，配置监控机 Windows 7

 

监控Windows 需要 安装snmp 协议 (简单网络管理协议)

 

 

在控制面板中找到“卸载程序”

在弹出的窗口中单击“打开或关闭Windows功能”

 

 

勾选弹出窗口中的“简单网络管理协议（SNMP）”项后单击“确定”并根据提示完成安装即可

 

 

 

完成SNMP服务的安装后，右键单击“计算机”选择“管理”

 

 

在弹出的“计算机管理”窗口中左侧导航栏中找到“服务”，并在右侧找到“SNMP Service”项

 

 

 

 

鼠标双击“SNMP Service”选项，在弹出的窗口中切换到“安全”选项卡中，如上图添加“接受的社区名称”和接收那些主机发出的SNMP数据包。

 

 

 

 

 

---------------------------------------------------------------------------------

2. 添加Linux 主机的监控

 

在Linux 下安装 snmp 服务

  

yum -y install net-snmp

 

设置开机自动启动 snmp服务

 

chkconfig snmpd on

 

启动 snmp 服务

 

service snmpd start

 

 

配置 snmp 服务

 

cd /etc/snmp/

 

mv snmpd.conf

 

vi snmpd.conf   修改下面内容

-------------------------------------------------------------

#       sec.name  source          community

com2sec notConfigUser  default       public

                 更改为

com2sec notConfigUser  10.8.8.11       public

 

------------------------------------------------------------------

 

 

-------------------------------------------------------------------------------

 

####

# Finally, grant the group read-only access to the systemview view.

 

#       group          context sec.model sec.level prefix read   write  notif

access  notConfigGroup ""      any       noauth    exact  systemview none none

 

将 systmview 更改为 all

 

-----------------------------------------------------------------------------------

 

 

 

------------------------------------------------------------------------------------

##           incl/excl subtree                          mask

#view all    included  .1                               80

 

去掉 #view 的注释

 

------------------------------------------------------------------------------------

 

 

 

成功以后会显示如下信息！

 

 

 

最后为主机添加图形

 

 

错误.1  不显示..

解决办法：

Console -> Data Source -> 选择没有图像的数据源 -> Turn On Data Source Debug MTurnode

复制到 Catic 安装主机 执行.

执行后会生成rrd文件

Data Source Debug 下面的 复制...
