1.安装数据库软件和其他软件

yum install mariadb-server net-snmp-utils net-snmp-devel policycoreutils-python

2.增加yum源

vi /etc/yum.repo.d/cactiez.repo

[CactiEZ]

name=CactiUsers Cactiez Repo

baseurl=http://mirror.cactiusers.org/RPMS/CentOS/$basearch/

enabled=1

gpgcheck=0

3.安装软件

yum -y install cactiez cactiez-plugin-boost cactiez-plugin-autom8 cactiez-plugin-jqueryskin cactiez-plugin-monitor cactiez-plugin-realtime cactiez-plugin-setup cactiez-plugin-syslog cactiez-plugin-ssl cactiez-plugin-templates cactiez-plugin-watermark cactiez-plugin-thold

4.编辑网站配置文件

vi /var/www/html/include/config.php

$database_type = "mysql";

$database_default = "davidcacti";

$database_hostname = "localhost";

$database_username = "davidcacti";      

$database_password = "123456";

$database_port = "13193";

$database_ssl = false;

$url_path = "/";

5.修改php时区

sed -i '/^;date.timezone/a\date.timezone = PRC' /etc/php.ini

6.启动服务

systemctl start httpd.service

systemctl start mariadb.service

systemctl start snmpd.service

7.配置数据库

mysql -uroot -p

use mysql

CREATE DATABASE `davidcacti` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

CREATE USER 'davidcacti'@'localhost' IDENTIFIED BY '123456';

GRANT ALL PRIVILEGES ON `davidcacti` . * TO 'davidcacti'@'localhost';

GRANT SELECT ON mysql.time_zone_name TO davidcacti@localhost;

use davidcacti

source  /var/www/html/cacti.sql

source  /var/www/html/cacti-changes.sql

8.修改数据库端口

vi /etc/my.cnf.d/server.cnf

[server]

port = 13193

semanage port -a -t mysqld_port_t -p tcp 13193

9.防火墙开启80端口

firewall-cmd --zone=public --add-port=80/tcp --permanent

systemctl restart firewalld

10.登陆网页打开流量图网站

注意开启插件：Autom8,Monitor,Jquerskin,Realtime,Syslog,Thold,Watermark

其他插件千万不要开启，有可能出现故障，导致无法访问，暂时未想好解决方法。

11.开启定期轮询

touch /etc/cron.d/cacti

echo "*/1 * * * * /usr/bin/php /var/www/html/poller.php > /dev/null 2>&1" > /etc/cron.d/cacti

echo "0 1 * * * nice -n 15 /var/www/backup.sh" >> /etc/cron.d/cacti

echo "0 2 * * * echo 3 > /proc/sys/vm/drop_caches" >> /etc/cron.d/cacti
