Cacti+Nagios(二)：安装Cacti

1、设置mysql，创建Cacti数据库和账号12345[root@nagios ~]# mysql -u root -p123456mysql> create database cactidb;mysql> GRANT ALL ON cactidb.* TO cactier@localhost IDENTIFIED BY 123456;

mysql> flush privileges;mysql> quit2、安装rrdtool1[root@nagios ~]# yum -y install rrdtool rrdtool-devel rrdtool-php

3、安装配置snmp12345[root@nagios ~]# yum install -y net-snmp net-snmp-utils net-snmp-libs[root@nagios ~]# vi /etc/snmp/snmpd.conf

可修改community默认密码public[root@nagios ~]# service snmpd restart[root@nagios ~]# chkconfig snmpd on4、下载安装Cacti

1234567[root@nagios ~]# mkdir /home/nagios[root@nagios ~]# cd /home/nagios[root@nagios nagios]# wget http://www.cacti.net/downloads/cacti-0.8.8b.tar.gz

[root@nagios nagios]# tar xzf cacti-0.8.8b.tar.gz[root@nagios nagios]# mv cacti-0.8.8b /var/www/html/cacti

[root@nagios cacti]# cd /var/www/html/cacti[root@nagios cacti]# mysql -uroot -p cactidb < cacti.sql5、配置参数

12345678[root@nagios cacti]# vi /var/www/html/cacti/include/config.php$database_type = “mysql”;$database_default = “cactidb”;

$database_hostname = “localhost”;$database_username = “cactier”;$database_password = “123456”;$database_port = “3306”;

#$url_path = “/cacti/”;6、添加用户、修改权限和属主123456[root@nagios cacti]# useradd cactier[root@nagios cacti]# passwd cactier

#输入密码123456[root@nagios cacti]# usermod -G cactier apache[root@nagios cacti]# chown -R root:root /var/www/html/cacti/

[root@nagios cacti]# chown -R cactier:cactier rra/ log/7、Apache设置12345678910[root@nagios cacti]# vi /etc/httpd/conf/httpd.conf

Options FollowSymLinks MultiViews AllowOverride None Order allow,deny

Allow from all[root@nagios cacti]# vi /etc/php.inidate.timezone=Asia/Shanghai[root@nagios cacti]# service httpd restart

8、添加计划每5分钟更新RRD图形，poller是单线程程序，可以改用支持多线程和分布式的工具spine1234[root@nagios cacti]# crontab -e*/5 * * * * php /var/www/html/cacti/poller.php &> /dev/null

[root@nagios cacti]# service crond restart[root@nagios cacti]# ntpdate 65.55.56.206切换用户,手动执行后在rra目录下生成rrd图形文件

12[root@nagios cacti]# su – cactier[cactier@nagios cacti]# php /var/www/html/cacti/poller.php也可以不执行手动操作，等待5分钟，观察rra目录下是否自动生成rrd文件

9、WEB页面初始化http://localhost/cacti用户名admin 密码admin

10、测试采集数据（1）查看RRD文件中数据123[cactier@nagios cacti]# cd /var/www/html/cacti/rra[cactier@nagios rra]# rrdtool fetch -r 300 localhost_mem_buffers_3.rrd AVERAGE

date +%s
