Mở đầu

Zabbix là gì?

Zabbix là một phần mềm doanh nghiệp mã nguồn mở giám sát các mạng và ứng dụng, được tạo ra bởi Alexei Vladishev và được công bố lần đầu tiên vào năm 2001. Nó được thiết kế để giúp admin mạng giám sát và theo dõi tình trạng của các dịch vụ mạng, máy chủ và phần cứng mạng khác một cách thông minh nhằm đảm bảo hệ thống luôn luôn được ổn định. – Theo Wikipedia

Trong bài lab, ta sẽ triển khai cài đặt từ source, rất cơ động để triển khai trên nhiều hệ điều hành khác nhau (centos, ubuntu, debian…).
zabbix monitoring system - hướng dẫn cài đặt zabbix

 

Các thành phần của zabbix bào gồm:

  • Zabbix Server
  • Zabbix frontend (chạy trên webserver LEMP hoặc LAMP)

Nếu bạn nào đã thạo cài webserver thì có thể bỏ qua bước cài đặt này, còn trong bài viết chúng ta sẽ cài đặt mọi thứ từ đầu.

Chuẩn bị hệ thống:

Vmware image: CENTOS 6.9, IP: 192.168.32.142

Hướng dẫn cài đặt zabbix server

Cấu hình tối thiểu để cài zabbix:

Name Platform CPU/Memory Database Monitored hosts
Small CentOS Virtual Appliance InnoDB 100
Medium CentOS 2 CPU cores/2GB MySQL InnoDB 500
Large RedHat Enterprise Linux 4 CPU cores/8GB RAID10 MySQL InnoDB or PostgreSQL >1000
Very large RedHat Enterprise Linux 8 CPU cores/16GB Fast RAID10 MySQL InnoDB or PostgreSQL >10000

Bước 1: cài đặt webserver.

Trong ví dụ, ta sẽ cài dặt webserver apache, PHP5.6 và MySql 5.6

Cài đặt MySql 5.6

wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm
wget https://dev.mysql.com/get/mysql57-community-release-el6-11.noarch.rpm
rpm -ivh mysql57-community-release-el6-11.noarch.rpm
rpm -ivh epel-release-latest-6.noarch.rpm

Cài đặt MySql thông qua yum:

yum install mysql-community-server mysql-community-devel

Chạy MySQL:

service mysql start
mysql_secure_installation

Cài đặt PHP 5.6

Mặc định, trên centos 6 chỉ có thể cài php5.3 qua yum, để cài php5.6 ta phải sử dụng repository khác.

Cài đặt PHP 5.6 qua yum:

yum install php php-cli php-common php-devel php-pear php-fpm php-gd php-bcmath php-mbstring php-xml php-mysql php-xmlwriter php-ldap

Cài đặt apache HTTP server:

yum install httpd httpd-devel

Cấu hình lại thông số php trong file /etc/php.ini cho phù hợp với yêu cầu của zabbix:

sed -i 's/^max_execution_time.*/max_execution_time=300/' /etc/php.ini
sed -i 's/^max_input_time.*/max_input_time=300/' /etc/php.ini
sed -i 's/^post_max_size.*/post_max_size=32M/' /etc/php.ini
sed -i 's/^upload_max_filesize.*/upload_max_filesize=16M/' /etc/php.ini
sed -i "s/^\;date.timezone.*/date.timezone=\'Asia\/Bangkok\'/" /etc/php.ini
sed -i "s/^\;always_populate_raw_post_data.*/always_populate_raw_post_data=-1/" /etc/php.ini

Đổi port mặc định của webserver để tăng bảo mật:

sed -i "s/^\Listen.*/Listen 8889/" /etc/httpd/conf/httpd.conf
echo "ServerName 127.0.0.1" >> /etc/httpd/conf/httpd.conf

Khởi chạy web server:

service httpd start

Kiểm tra web server & PHP đã chạy chưa:

echo "<?php phpinfo(); ?>" > /var/www/html/info.php
curl -I localhost:8889/info.php
HTTP/1.1 200 OK
Date: Thu, 09 Nov 2017 09:47:57 GMT
Server: Apache/2.2.15 (CentOS)
X-Powered-By: PHP/5.6.31
Connection: close
Content-Type: text/html; charset=UTF-8

Bước 2: Cài đặt zabbix server & zabbix agent

Tải source Zabbix:

Các phiên bản Zabbix có thể tại tại:
https://sourceforge.net/projects/zabbix/files/
Tải Bản mới nhất: 3.4.2:
https://sourceforge.net/projects/zabbix/files/ZABBIX%20Latest%20Stable/3.4.2/zabbix-3.4.2.tar.gz

cd /usr/local/src/
wget https://sourceforge.net/projects/zabbix/files/ZABBIX%20Latest%20Stable/3.4.2/zabbix-3.4.2.tar.gz

Xả nén bộ cài:

tar -xzvf zabbix-3.4.2.tar.gz

Cài đặt Cơ sở dữ liệu cho Zabbix

* Tạo CSDL zabbix:

# mysql -u root -p
create database zabbix character set utf8 collate utf8_bin;
grant all privileges on zabbix.* to zabbix@localhost identified by '123456';
flush privileges;
Enter password:

Bye

* Import cấu trúc CSDL của zabbix :

cd /usr/local/src/zabbix-3.4.2/database/mysql/
mysql -u root -p -D zabbix < schema.sql
mysql -u root -p -D zabbix < images.sql
mysql -u root -p -D zabbix < data.sql

Build Zabbix server và cấu hình:

* Cài đặt các thư viện cần thiết để build source:

# yum install gcc make libxml2-devel net-snmp-devel libcurl-devel libssh2-devel libevent-devel pcre-devel iksemel-devel java-1.8.0-openjdk-devel openldap-devel openssl-devel

* Tiến hành build source:

groupadd zabbix
useradd -g zabbix zabbix
cd /usr/local/src/zabbix-3.4.2
./configure --enable-server --enable-agent --prefix=/usr/local --sysconfdir=/etc/zabbix --enable-java --with-mysql --with-jabber --with-libcurl --with-net-snmp --with-ldap --with-iconv --with-libxml2 --with-openssl
make
make install
chown zabbix:zabbix /var/log/zabbix/
mkdir /var/run/zabbix/
chown zabbix:zabbix /var/run/zabbix/

* Sửa file /etc/zabbix/zabbix_server.conf thành:

LogFileSize=500
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=123456
PidFile=/var/run/zabbix/zabbix_server.pid

* Sửa file /etc/zabbix/zabbix_agentd.conf thành:

* Chạy server & agent:

server zabbix_server start
service zabbix_agentd start

Cài đặt zabbix web frontend:

* Copy frontend source code vào thư mục chứa website:

mkdir /var/www/html/zabbix
cp -a /usr/local/src/zabbix-3.4.2/frontends/php/* /var/www/html/zabbix
chown -R apache:apache /var/www/html/zabbix/

Kết thúc việc cài đặt zabbix, tiếp theo t a sẽ cấu hình zabbix frontend kết nối với zabbix_server

Bước 3: Cấu hình zabbix Frontend.

Truy cập địa chỉ http://192.168.32.142:8889/zabbix

Kết Luận

Qua một bài viết dài, chúng ta đã nắm được cách cài đặt zabbix server và cấu hình client bằng zabbix agent. Nếu bạn nào có nhu cầu tìm hiểu thêm có thể theo dõi thêm một số bài viết sau: cách monitor server windows/linux bằng agent, snmp, cấu hình gửi cảnh báo qua mail, sms.

Với bạn nào “lười” cài đặt từ source code, mình có build 1 script cài đặt tự động trên debian 9: các bạn có thể tham khảo.
