- Fitila atupa sori ẹrọ ni Debian 9
- LAMP Stack Fi sori ẹrọ ni Ubuntu 16.04 LTS
Igbesẹ 1: Fi sori ẹrọ ati Tunto Awọn ohun pataki fun Cacti
1. Ni Debian 9, ṣii akojọ faili awọn orisun fun ṣiṣatunkọ ati ṣafikun awọn idasi ati awọn ibi ipamọ ti kii ṣe ọfẹ si faili naa nipa yiyipada awọn ila wọnyi:
# nano /etc/apt/sources.list
Ṣafikun awọn ila atẹle si faili Source.list.
deb http://ftp.ro.debian.org/debian/ stretch main contrib non-free deb-src http://ftp.ro.debian.org/debian/ stretch main deb http://security.debian.org/debian-security stretch/updates main contrib non-free deb-src http://security.debian.org/debian-security stretch/updates main
2. Lẹhinna, rii daju lati ṣe imudojuiwọn eto nipa ipinfunni aṣẹ isalẹ.
# apt update # apt upgrade
3. Ninu akopọ LAMP rẹ rii daju pe awọn amugbooro PHP wọnyi wa ninu eto naa.
# apt install php7.0-snmp php7.0-xml php7.0-mbstring php7.0-json php7.0-gd php7.0-gmp php7.0-zip php7.0-ldap php7.0-mcrypt
4. Itele, satunkọ faili iṣeto PHP ki o yi eto agbegbe aago pada lati baamu ipo ti ara olupin rẹ, nipa ipinfunni aṣẹ isalẹ.
# echo "date.timezone = Europe/Bucharest" >> /etc/php/7.0/apache2/php.ini
5. Nigbamii, wọle si MariaDB tabi ibi ipamọ data MySQL lati fifi sori akopọ LAMP rẹ ki o ṣẹda ipilẹ data fun fifi Cacti sii nipa fifun awọn ofin wọnyi.
Rọpo orukọ ibi ipamọ data cacti, olumulo ati ọrọ igbaniwọle lati baamu awọn atunto tirẹ ati yan ọrọ igbaniwọle ti o lagbara fun ibi ipamọ data cacti.
# mysql -u root -p mysql> create database cacti; mysql> grant all on cacti.* to 'cactiuser'@'localhost' identified by 'password1'; mysql> flush privileges; mysql> exit
6. Pẹlupẹlu, ṣe agbejade awọn ofin isalẹ lati gba olumulo cacti yan awọn igbanilaaye si eto MySQL data.timezone nipa ipinfunni awọn ofin isalẹ.
# mysql -u root -p mysql < /usr/share/mysql/mysql_test_data_timezone.sql # mysql -u root -p -e 'grant select on mysql.time_zone_name to [email '
7. Itele, ṣii faili iṣeto ni olupin MySQL ki o ṣafikun awọn ila wọnyi ni ipari faili naa.
# nano /etc/mysql/mariadb.conf.d/50-server.cnf [For MariaDB] # nano /etc/mysql/mysql.conf.d/mysqld.cnf [For MySQL]
Ṣafikun awọn ila wọnyi si opin faili 50-server.cnf tabi faili mysqld.cnf.
max_heap_table_size = 98M tmp_table_size = 64M join_buffer_size = 64M innodb_buffer_pool_size = 485M innodb_doublewrite = off innodb_flush_log_at_timeout = 3 innodb_read_io_threads = 32 innodb_write_io_threads = 16
Fun ibi ipamọ data MariaDB tun ṣafikun laini atẹle si opin faili 50-server.cnf:
innodb_additional_mem_pool_size = 80M
8. Lakotan, tun bẹrẹ MySQL ati awọn iṣẹ Apache lati lo gbogbo awọn eto ati ṣayẹwo ipo awọn iṣẹ mejeeji nipasẹ ipinfunni awọn ofin wọnyi.
# systemctl restart mysql apache2 # systemctl status mysql apache2
Igbese 2: Gbaa lati ayelujara ati Mura Fifi sori Cacti
9. Bẹrẹ fi sori ẹrọ Cacti lati awọn orisun nipasẹ gbigba lati ayelujara ati yiyo ẹya tuntun ti iwe akọọlẹ Cacti ati daakọ gbogbo awọn faili iyọkuro si gbongbo iwe wẹẹbu Apache, nipa ipinfunni awọn ofin wọnyi.
# wget https://www.cacti.net/downloads/cacti-latest.tar.gz # tar xfz cacti-latest.tar.gz # cp -rf cacti-1.1.27/* /var/www/html/
10. Yọ faili index.html lati/var/www/html liana, ṣẹda faili log Cacti ki o fun Afun pẹlu fifun awọn igbanilaaye si ọna gbongbo wẹẹbu.
# rm /var/www/html/index.html # touch /var/www/html/log/cacti.log # chown -R www-data:www-data /var/www/html/
11. Itele, satunkọ faili iṣeto cacti ki o yipada awọn ila wọnyi bi o ṣe han ninu apẹẹrẹ isalẹ.
# nano /var/www/html/include/config.php
Ayẹwo faili Cacti config.php. Rọpo orukọ data data cacti, olumulo ati ọrọ igbaniwọle ni ibamu.
$database_type = 'mysql'; $database_default = 'cacti'; $database_hostname = 'localhost'; $database_username = 'cactiuser'; $database_password = 'password1; $database_port = '3306'; $database_ssl = false; $url_path = '/';
12. Nigbamii, ṣafikun ibi ipamọ data cacti pẹlu iwe afọwọkọ cacti.sql lati/var/www/html/liana nipa ipinfunni aṣẹ isalẹ.
# mysql -u cactiuser cacti -p < /var/www/html/cacti.sql
13. Nisisiyi fi diẹ ninu awọn orisun sii, bi ẹrọ Cacti ṣe n gba data awọn ẹrọ nipasẹ ilana SNMP ati ṣafihan awọn aworan nipasẹ lilo RRDtool. Fi gbogbo wọn sii nipa fifun pipaṣẹ atẹle.
# apt install snmp snmpd snmp-mibs-downloader rrdtool
14. Ṣayẹwo ti iṣẹ SNMP ba wa ni oke ati ṣiṣe nipasẹ tun bẹrẹ daemon snmpd nipasẹ ipinfunni aṣẹ isalẹ. Tun ṣayẹwo ipo daemon snmpd ati awọn ibudo ṣiṣi rẹ.
# systemctl restart snmpd.service # systemctl status snmpd.service # ss -tulpn| grep snmp
Igbesẹ 3: Gbaa lati ayelujara ati Fi Cacti-Spine sii
15. Cacti-Spine jẹ rirọpo kikọ C ti a fiweranṣẹ fun oludibo cmd.php aiyipada. Cacti-Spine pese akoko ipaniyan yiyara. Lati ṣajọ talaka ti Cacti-Spine lati awọn orisun fi sori ẹrọ awọn igbẹkẹle ti o nilo ni isalẹ ninu eto rẹ.

16. Lẹhin ti o ti fi awọn igbẹkẹle ti o wa loke sii, ṣe igbasilẹ ẹya tuntun ti iwe-akọọlẹ Cacti-Spine, fa jade tarball ati ṣajọ ọpa-ẹhin cacti nipasẹ ipinfunni awọn atẹle awọn ofin wọnyi.
# wget https://www.cacti.net/downloads/spine/cacti-spine-latest.tar.gz # tar xfz cacti-spine-latest.tar.gz # cd cacti-spine-1.1.27/
17. Ṣajọ ati fi Cacti-Spine sori ẹrọ lati awọn orisun nipa ipinfunni awọn ofin wọnyi.

19. Nisisiyi, satunkọ faili iṣeto Cacti Spine ati ṣafikun orukọ ibi ipamọ data cacti, aṣàmúlò ati ọrọ igbaniwọle si faili Spine conf bi a ti ṣe apejuwe ninu apẹẹrẹ isalẹ.

Igbesẹ 4: Oṣo Oluṣeto Fifi sori Cacti
20. Lati fi Cacti sii, ṣii ẹrọ lilọ kiri ayelujara kan ki o lilö kiri si adirẹsi IP eto rẹ tabi orukọ ìkápá ni URL atẹle.
