centos 安装cacti监控

CentOS 6下Cacti搭建文档

安装依赖关系

yum -y install  mysql-devel httpd php php-pdo php-snmp php-mysql lm_sensors net-snmp net-snmp-utils net-snmp-libs rrdtool rrdtool-devel perl-PlRPC perl-DBI perl-rrdtool perl-DBD-MySQL

http配置

alias /cacti /home/op/cacti/
<Directory /home/op/cacti/>
Options Indexes
AllowOverride AuthConfig Options
Order allow,deny
Allow from all
</Directory>

1.安装需要的库文件

yum -y install zlib freetype libjpeg fontconfig gd libxml2 php-gd http 

2. 安装RRDTool

   yum -y install rrdtool

3. 安装snmp支持工具

   yum -y install net-snmp net-snmp-utils

   启动snmpd服务并且加入启动列表

   service snmpd start

   chkconfig snmpd on

4.安装cacti

下载

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

配置

解压并放到/home/op

tar xzf cacti-0.8.8h.tar.gz

mv cacti-0.8.8h cacti

（注：最好重命名cacti-0.8.8h文件夹为cacti 便于访问。）

编辑CentOS cacti配置文件，连接MySQL服务的用户名，密码，端口等。

cd /home/op

vi cacti/include/config.php

$database_type = "mysql";

$database_default = "cacti";

$database_hostname = "192.168.100.52";

$database_username = "cacti";

$database_password = "cacti";

$database_port = "3306″;

添加计划任务(使cacti每5分钟获得一次数据)
添加一个cacti的用户并添加cron任务:

useradd cacti

su cacti

crontab -e

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

更改属组
把cacti网站目录所属组改为cacti

su root

chgrp -R cacti /home/op/cacti

chown -R cacti /home/op/cacti/rra

chown -R cacti /home/op/cacti/log

chown -R cacti /home/op/cacti/poller.php

5 数据库配置

登录

/home/xiaohe/mysql/bin/mysql -uroot -p

重启命令

/home/xiaohe/superctl restart mysql

创建cacti数据库

msyql>create database cacti;

导入cacti.sql

/home/xiaohe/mysql/bin/mysql -uroot -p cacti < /home/op/cacti/cacti.sql

有密码的输入密码,没密码的直接回车
应用

mysql> use cacti

授权

mysql> grant all on cacti.* to cacti@localhost identified by 'cacti';
       grant select,insert,update,delete on cacti.* to cacti@192.168.100.52 identified by 'cacti' with grant option; 

刷新

mysql> flush privileges;
mysql> exit

snmp 配置

com2sec notConfigUser  192.168.100.52       public
group   notConfigGroup v1           notConfigUser
group   notConfigGroup v2c           notConfigUser
view    systemview    included   .1.3.6.1.2.1.1
view    systemview    included   .1.3.6.1.2.1.25.1.1
access  notConfigGroup ""      any       noauth    exact  mib2 none none
view all    included  .1                               80
view mib2   included  .iso.org.dod.internet.mgmt.mib-2 fc
syslocation 天上人间 (edit /etc/snmp/snmpd.conf)
syscontact Root <root@localhost> (configure /etc/snmp/snmp.local.conf)
dontLogTCPWrappersConnects yes

记得重启snmp和httpd

WEB登陆cacti

http://ip/cacti


（这里如果出现"403 forbidden"的错误,请把selinux关闭）
（cacti 默认密码无法登陆 cd /var/lib/php/  chmod 777 session/）
 打开网页—>next—>选择new install,使用一路回车法.完成的用户名为: admin 密码为: admin (初次登陆成功会提示更改密码)

监控客户端配置

yum -y install net-snmp
mv /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf.bak
/etc/init.d/snmpd restart

服务端

将服务端的配置文件拷贝到客户端
scp /etc/snmp/snmpd.conf root@192.168.100.63:/etc/snmp/

测试是否成功
nc -vuz 192.168.100.55 161



chkconfig snmpd on
/etc/init.d/snmpd restart
