Cài cacti trên centos 6 tự động trong 1 nốt nhạc

Cacti là một ứng dụng monitor hệ thống khá tốt với một số tính năng độc đáo.
Bài viết này hướng đẫn cách cài đặt cacti lên centos 6 chỉ với 1 cú enter.
Bắt đầu thôi

1. Chuẩn bị server

Server: Centos 6.x bản 64bit
Ram: 512mb trở lên
HDD: 8GB trở lên.

Note: script cài được cho bản 32 bit, tuy nhiên 1 số plugin 32 bit hiện không tìm thấy nữa :) nên nếu sử dụng 32bit thì chấp nhận thiếu hụt vài tính năng.

2. Cài đặt.

Tạo file /root/cacti_install.sh với nội dung sau:

service httpd restart

Cuối cùng chạy lệnh:

# sh cacti_install.sh



Pha 1 tách cafe rồi ngồi đợi thôi :)




3. Cấu hình cacti:


Sau khi cài đặt xong, truy cập vào địa chỉ : http://IP_server/cacti

Tài khoản mặc định: admin password admin

Bấm Ok để lưu cấu hình.

Vào setting/poller

Chọn poller là spin rồi ấn save

Vậy là xong

Các bước add host vào cacti các bạn tự google nhé :)

Cài đặt zabbix 3.4 trên centos 6 từ mã nguồn

STEP TO SUCCESS!
ZABBIX INSTALLATION FROM SOURCE

Mục tiêu: build zabbix 3.4.2 từ mã nguồn

---------------------------------------------------------
System:
VM: CENTOS 6.9 F, IP: 192.168.32.142
PHP: 5.6
SQL: MYSQL 5.6
---------------------------------------------------------

Vì sao là Centos 6?

Chủ yếu là vì trên centos 7, ubuntu hay debian thì cài thẳng từ repo cho lẹ :). Ở VN mọi người vẫn rất hay dùng centos 6 - vì thói quen thôi.
Hiện trên centos 6 chỉ có thể cài zabbix_agent thông qua yum.
Đây chính là mục đích của bài viết này: Tự build zabbix trên centos 6 (latest release: centos 6.9F).

P1. Install MySql Server

*Install 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

Sửa Nội dung file /etc/yum.repos.d/mysql-community.repo
....
# Enable to use MySQL 5.6
[mysql56-community]
name=MySQL 5.6 Community Server
baseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/6/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

[mysql57-community]
name=MySQL 5.7 Community Server
baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/6/$basearch/
enabled=0
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
....

* Cài đặt MySQL:

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

* Bảo mật MySql:

# service mysql start
# mysql_secure_installation

P2. 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

P3. Cài đặt Cơ sở dữ liệu cho Zabbix

* Tạo CSDL zabbix:

# mysql -u root -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 13
Server version: 5.6.37 MySQL Community Server (GPL)
Copyright (c) 2000, 2017, Oracle and/or its affiliates. All rights reserved.
Oracle is a registered trademark of Oracle Corporation and/or its
affiliates. Other names may be trademarks of their respective
owners.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql> create database zabbix character set utf8 collate utf8_bin;
Query OK, 1 row affected (0.00 sec)
mysql> grant all privileges on zabbix.* to zabbix@localhost identified by '123456';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> quit
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

P4. 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:

LogFile=/var/log/zabbix/zabbix_server.log
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:

# This is a configuration file for Zabbix agent daemon (Unix)
# To get more information about Zabbix, visit http://www.zabbix.com
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=200

* Chạy server & agent:

# server zabbix_server start
# service zabbix_agentd start

P5. Cài đặt Zabbix web Frontend

Chúng ta sẽ sử dụng LAMP stack để chạy web server. Bước trên đã cài MySQL rồi, dưới đây ta cài PHP 5.6 và apache
Trên centos 6 để cài PHP 5.5 trở lên ta dùng remi repo

* Install epel remi repo

# wget https://rpms.remirepo.net/enterprise/remi-release-6.rpm
# rpm -Uvh remi-release-6.rpm epel-release-latest-6.noarch.rpm
# nano /etc/yum.repos.d/remi.repo

=> Sửa Nội dung: /etc/yum.repos.d/remi.repo

...
[remi-php56]
name=Remi's PHP 5.6 RPM repository for Enterprise Linux 6 - $basearch
#baseurl=http://rpms.remirepo.net/enterprise/6/php56/$basearch/
#mirrorlist=https://rpms.remirepo.net/enterprise/6/php56/httpsmirror

# NOTICE: common dependencies are in "remi-safe"
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi
...

* Cài dặt PHP 5.6 bằng lệnh  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 web server:

# yum install httpd httpd-devel

* 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/

* Cấu hình php phù hợp với yêu cầu của Zabbix:

Pre-requisite	Minimum value	Description
PHP version	5.4.0
PHP memory_limit option	128MB	In php.ini: memory_limit = 128M
PHP post_max_size option	16MB	In php.ini: post_max_size = 16M
PHP upload_max_filesize option	2MB	In php.ini: upload_max_filesize = 2M
PHP max_execution_time option	300 seconds (values 0 and -1 are allowed)	In php.ini: max_execution_time = 300
PHP max_input_time option	300 seconds (values 0 and -1 are allowed)	In php.ini: max_input_time = 300
PHP session.auto_start option	must be disabled	In php.ini: session.auto_start = 0
PHP mbstring.func_overload option	must be disabled	In php.ini: mbstring.func_overload = 0
PHP always_populate_raw_post_data option	must be disabled	Required only for PHP versions 5.6.0 or newer. In php.ini: always_populate_raw_post_data = -1
sockets		php-net-socket. Required for user script support.

Có thể sửa trực tiêp trong file /etc/php.ini
Hoặc dùng lệnh:

# 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

Để bảo mật, đổi port chạy của webserver:

# sed -i "s/^\Listen.*/Listen 8889/" /etc/httpd/conf/httpd.conf

* Khởi động apache:

# service httpd start

Tiếp theo cài đặt các thông số trên front-end: Nhập các thông số theo server đã tạo

DB: zabbix
DB Port: 3306
USER: zabbix
Passwod: 123456

Đăng nhập vào zabbix Dashboard

username: Admin
Password: zabbix

Vào phần Configuration/Host và enable host:

vậy là xong!
