linux安装cacti

一、环境准备

1、安装epel扩展源

[[email protected] ~]# yum install -y epel-release

2、搭建lamp环境

[[email protected] ~]

# yum install -y  httpd php php-mysql mysql mysql-server mysql-devel php-gd  libjpeg libjpeg-devel libpng-devel

[[email protected] ~]# /etc/init.d/httpd start

正在启动 httpd： [确定]

[[email protected] ~]# /etc/init.d/mysqld start

初始化 MySQL 数据库： Installing MySQL system tables...

OK

Filling help tables...

OK

To start mysqld at boot time you have to copy

support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !

To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'

/usr/bin/mysqladmin -u root -h cacti password 'new-password'

Alternatively you can run:

/usr/bin/mysql_secure_installation

which will also give you the option of removing the test

databases and anonymous user created by default. This is

strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

cd /usr ; /usr/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

cd /usr/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/bin/mysqlbug script!

[确定]

正在启动 mysqld： [确定]

3、安装cacti监控主机

[[email protected] ~]

# yum install -y cacti  net-snmp  net-snmp-utils  rrdtool net-snmp-devel net-snmp-libs lm-sensors php-xml zlib libpng freetype cairo-devel pango-devel gd

[[email protected] ~]# /etc/init.d/snmpd start

正在启动 snmpd： [确定]

[[email protected] ~]# mysql -u root

Welcome to the MySQL monitor. Commands end with ; or \g.

Your MySQL connection id is 4

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> create database cacti;

mysql> grant all on cacti.* to 'cactiuser'@'localhost' identified by 'cactiuser';

Query OK, 0 rows affected (0.00 sec)

mysql> exit

Bye

[[email protected] ~]# mysql -u root cacti < /usr/share/doc/cacti-0.8.8b/cacti.sql

[[email protected] ~]# vim /usr/share/cacti/include/config.php

$database_type = "mysql";

$database_default = "cacti";

$database_hostname = "localhost";

$database_username = "cactiuser";

$database_password = "cactiuser";

$database_port = "3306";

$database_ssl = false;

[[email protected] ~]# vim /etc/httpd/conf.d/cacti.conf

Deny from all 修改为 Allow from all

[[email protected] ~]# /etc/init.d/httpd restart

停止 httpd： [确定]

正在启动 httpd： [确定]

4、通过浏览器访问

如果访问不了，请检查主机的iptables和selinux

图：一

图：二

图：三

到了登陆，默认的账号为admin，密码为admin

图：四

登陆之后，系统会强制用户更改密码

图：五

图：六

点击graphs-Default Tree-Host Localhost，进入系统监控界面

图：七

我们看到监控界面，没有出图，设置一下出图

[[email protected] ~]# /usr/bin/php /usr/share/cacti/poller.php

OK u:0.00 s:0.00 r:0.00

OK u:0.00 s:0.00 r:0.01

OK u:0.00 s:0.00 r:0.03

OK u:0.00 s:0.00 r:0.05

OK u:0.00 s:0.00 r:0.08

[[email protected] ~]# crontab -e

# 让命令每5分钟执行一次

*/5 * * * * /usr/bin/php /usr/share/cacti/poller.php > /dev/null 2>&1

我们在刷新一下，图就出来了

图：八

数据需要等待一会儿，才能出来

接下来我们添加被监控的主机

# 在被监控的主机上安装

[[email protected] ~]# yum install -y net-snmp lm_sensors

[[email protected] ~]# vim /etc/snmp/snmpd.conf

#syslocation Unknown (edit /etc/snmp/snmpd.conf)

syslocation 192.168.1.118

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

access notConfigGroup "" any noauth exact all none none

view all    included  .1                               80    去掉注释符“

#”

[[email protected] ~]# /etc/init.d/snmpd start

正在启动 snmpd： [确定]

依次点击console -> Devices -> add,添加主机

开始添加被监控主机的信息，填写完毕，点击Create

创建完毕，看是否通信正常，创建完主机，创建要监控的项目点击 Create Graphs for this Host，

根据需要，去选择要监控的项目

监控项目添加完毕，将主机添加到监控主干线上，点击左侧Graph Trees

点击Add，添加被监控的主机

类型选择Host，再选择要添加的主机

添加完毕，点击Save

到主界面查看，是否添加成功，最好在监控服务器上刷新一下

[[email protected] ~]# /usr/bin/php /usr/share/cacti/poller.php --force

OK u:0.00 s:0.00 r:0.00

OK u:0.00 s:0.00 r:0.01

OK u:0.00 s:0.00 r:0.03

OK u:0.00 s:0.00 r:0.05

OK u:0.00 s:0.00 r:0.08

OK u:0.00 s:0.00 r:0.09

cacti监控主机执行/usr/bin/php /usr/share/cacti/poller.php --force报错解决

解决方法：

现在再次执行就不会报错了

如果报这个错

解决方法：

cacti检测找不到网卡解决方法：

功夫不负有心人，终于各种测试，找到了昨晚试验没出现的网卡；
方法如下：
前面的所有步骤和铭哥论坛帖子一样。web里面的配置也一样。后面找到的配置不需要修改；（按照配置修改后会提示snmp error错误）
只需要在客户机（你要监控的机器）修改配置文件：
[[email protected] ~]# vi /etc/snmp/snmpd.conf

view systemview included .1.3.6.1.2.1.1
修改为:
view systemview included .1.3.6.1.2.1

然后重启snmpd服务；
[[email protected] ~]# /etc/init.d/snmpd restart

在web监控里面添加
linux安装cacti

类型选择Graph Types: SNMP - Interface Statistics 就看到你客户机的网卡了。点击create。保存。
linux安装cacti

在Graphs中就可以看到添加的网卡流量信息了；
