Cacti 설치

cacti는 RRDTool의 데이터베이스를 이용하여 웹에서 시스템 상황을 데이터값으로 저장하고 시간이 흐른 뒤

저장된 데이터를 분석하여 웹상으로 보여주는 모니터링 시스템이다.

cacti는 php를 기반으로 하므로 php가 설치되어 있어야하며, CentOS 설치부터 따라하셨다면 설치가 될 것이다.



STEP 1.

Cacti 다운 받는다.

[root@Cacti download]# pwd
/download
[root@Cacti download]# lftpget http://www.cacti.net/downloads/cacti-0.8.7c.tar.gz


다운 받은 Cacti 파일을 압축을 푼다.

[root@Cacti download]# tar xvfz cacti-0.8.7c.tar.gz

STEP 2.

Cacti 데이터 파일을 저장하기 위해 mysql에 데이터베이스를 생성한다.

[root@Cacti cacti-0.8.7c]# mysqladmin create cacti -u root -p
Enter password:
[root@Cacti cacti-0.8.7c]#


Cacti 데이터베이스에 필요한 테이블과 기본 데이터 생성하기

[root@Cacti cacti-0.8.7c]# mysql cacti < cacti.sql -u root -p
Enter password:
[root@Cacti cacti-0.8.7c]#



Cacti 데이터베이스 접근권한을 설정한다.

[root@Cacti cacti-0.8.7c]# mysql mysql -u root -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 6
Server version: 5.0.75-log Source distribution

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY '여기에 패스워드를 입력';
Query OK, 0 rows affected (0.05 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql>


mysql 권한 설정 후 권한 재설정 사항을 적용하기 위해서 flush privilesges; 명령어를 수행한 것이다.

위의 기본제공되는 cacti.sql 파일을 mysql에 저장하였다. 저장된 mysql 데이터 베이스를 아래와 같이 확인 해 본다.

mysql> show databases;

| mysql              |
| test               |
+--------------------+
4 rows in set (0.01 sec)

mysql> quit
Bye
[root@Cacti cacti-0.8.7c]#




STEP 3.

기본 데이터 베이스를 확인한 다음 Cacti의 접속 환경설정 php 파일을 수정한다.

[root@Cacti cacti-0.8.7c]# vi include/config.php

*/

/* make sure these values refect your actual database/host/user/password */
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cactiuser";
$database_password = "cactiuser";
$database_port = "3306";

/* Default session name - Session name must contain alpha characters */
#$cacti_session_name = "Cacti";

?>

아래와 같이 수정했다.

<?php

?>




데이터파일과 로그파일이 저장될 디렉토리의 퍼미션을 변경한다.

[root@Cacti cacti-0.8.7c]# chmod 777 rra log
[root@Cacti cacti-0.8.7c]#




웹서버 디렉토리 안에 cacti 디렉토리를 심볼릭링크를 건다.

[root@Cacti cacti-0.8.7c]# ln -s /download/cacti-0.8.7c /usr/local/server/apache/htdocs/cacti
[root@Cacti cacti-0.8.7c]#




STEP 4.

RRDtool을 설치해야 한다. 필자가 써 놓은 RRDtool 설치를 보고 RRDtool을 먼저 설치한다.




STEP 5.

웹브라우저를 이용하여 cacti 링크를 걸어둔 URL로 접속 한다.
