Instalando Zabbix 4.0 no Oracle Linux 7.5
Olá pessoal, eu sou o Bruno Tarnowski e este é meu primeiro artigo no blog.
Trabalho com banco de dados há cerca de 7 anos onde parte deles foram em uma Software House e mais recentemente tenho trabalhado exclusivamente em consultoria de serviços, juntamente com o Franky.
Atualmente meu foco é em Oracle, onde presto consultoria para parceiros da região e diversos clientes, acabo atuando também com SQL Server, MySQL e com algumas demandas de sistemas operacionais Windows e em sua maioria Linux.
Bom, chega de papo e vamos ao que interessa!
Hoje instalaremos o Zabbix Server 4.0 no Oracle Linux 7.5.
O Zabbix é uma ferramenta open-source que pode ser utilizada para monitorar toda sua infra-estrutura, desde aplicações até a camada de banco de dados, redes, protocolo SNMP, imap e outra infinidade de itens.
Para utilização do Zabbix precisamos ter um servidor que coletará os dados dos hospedeiros e em cada hospedeiro um agente que servirá para fazer a comunicação até o servidor. Há outros métodos para coletar os dados, como por exemplo o Zabbix Proxy, mas não entrarei em detalhes, pois sempre haverá um Zabbix Server para receber os dados coletados e este é o foco do artigo de hoje.
Após sua instalação, são coletados dados para o monitoramento de forma contínua e quando alguma anormalidade é detectada, alertas são emitidos visualmente e através de uso de sistemas de comunicação como e-mail e SMS. É possível manter o histórico destes dados coletados configurando retenções em período de tempo e com elas podem ser gerados gráficos e painéis de acompanhamento.
O servidor do Zabbix deve ser obrigatoriamente instalado em sistemas Unix ou Linux.
Pré-requisitos do Zabbix Server 4.0
Primeiramente temos que habilitar o repositório PHP no yum, pois alguns pacotes do Zabbix Server possuem dependência com ele.
Para isso, vamos acessar o arquivo “/etc/yum.repos.d/public-yum-ol7.repo” e alterar o parâmetro “enabled” do repositório “[ol7_developer_php72]” para o valor “1”:
[root@hawkeye ~]# vi /etc/yum.repos.d/public-yum-ol7.repo ... [ol7_developer_php72] name=Oracle Linux $releasever PHP 7.2 Packages for Development and test ($basearch) baseurl=https://yum.oracle.com/repo/OracleLinux/OL7/developer_php72/$basearch/ gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle gpgcheck=1 enabled=1 ...
Em seguida vamos instalar o Apache HTTP Server:

Em seguida vamos instalar o banco de dados que armazenará os dados consumidos pelo Zabbix Server.
O Oracle Linux 7.5 não possui bibliotecas do MySQL (meio estranho, já que o MySQL é da Oracle), então vamos instalar o MariaDB (), que possui praticamente a mesma estrutura de banco de dados e é homologado.

Vamos habilitar o Apache HTTP Server e o MariaDB para iniciarem automaticamente com o boot do SO e em seguida, iniciar o serviço:
[root@hawkeye ~]# systemctl enable httpd Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service. [root@hawkeye ~]# systemctl start httpd [root@hawkeye ~]# systemctl enable mariadb Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service. [root@hawkeye ~]# systemctl start mariadb
É importante efetuarmos algumas configurações nas políticas de segurança do MariaDB, inclusive mudar a senha de root do banco de dados:
[root@hawkeye ~]# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] Y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] Y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] Y
... Success!
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] Y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] Y
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
Instalação e configuração do Zabbix Server 4.0
Vamos importar a chave de criptografia do repositório do Zabbix no nosso servidor para que os arquivos possam verificar a autenticidade e em seguida vamos baixar a versão 4.0 do Zabbix Server para a máquina:

Acontece que o repositório yum já possui a versão 7 e o Zabbix atualmente é homologado até a versão 5.
Para não precisarmos baixar uma versão específica manualmente do PHP e desabilitar o repositório (para não pegar a última versão automaticamente na atualização manual), vamos fazer a instalação do zabbix-web que é recomendada para instalações quando o banco de dados é o PostgreSQL, porém no nosso caso, precisamos apenas que a instalação crie os arquivos de configuração do front-end, pois os pacotes do PHP já foram instalados em passos anteriores.
Nosso único contraponto serão os pacotes adicionais do PostgreSQL que serão instalados, porém não são muitos e não irão impactar no uso comum do ambiente.

Temos que efetuar algumas configurações do PHP no Apache HTTP Server, para ser compatível com as recomendações do Zabbix Server. Se estas configurações estiverem incorretas, ao iniciar o Apache HTTP Server e acessar a página do Zabbix, ele irá reclamar que as configurações não estão de acordo com o mínimo recomendável.
As seguintes configurações devem estar com o valor mínimo recomendado configurado no arquivo “/etc/php.ini”:
[root@hawkeye ~]# vi /etc/php.ini ... php_value max_execution_time 300 php_value memory_limit 128M php_value post_max_size 16M php_value upload_max_filesize 2M php_value max_input_time 300 php_value max_input_vars 10000 php_value always_populate_raw_post_data -1 php_value date.timezone America/Sao_Paulo ...
Vamos recarregar o arquivo de parâmetros do PHP no Apache HTTP Server para utilizar as novas configurações efetuadas:
[root@hawkeye ~]# systemctl reload httpd
Agora iremos efetuar a configuração do banco de dados para o Zabbix Server:
[root@hawkeye ~]# mysql -u root -p Enter password: Welcome to the MariaDB monitor. Commands end with ; or g. Your MariaDB connection id is 10 Server version: 5.5.60-MariaDB MariaDB Server Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others. Type 'help;' or 'h' for help.

Em seguida vamos importar os dados iniciais para o database do Zabbix Server:
[root@hawkeye ~]# zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix Enter password:
Vamos verificar o novo database criado e as suas tabelas:

Neste momento precisamos ajustar os parâmetros de configuração entre a instância do Zabbix Server e o banco de dados criado.
Os parâmetros DBHost e DBPassword devem ser descomentados e definidos no arquivo “/etc/zabbix/zabbix_server.conf”:
[root@hawkeye ~]# vi /etc/zabbix/zabbix_server.conf
Se você está com o firewall ativo nesta máquina, é necessário criar uma exceção para o serviço HTTP e abrir as duas portas que serão utilizadas pelo Zabbix Server:
[root@hawkeye ~]# firewall-cmd --permanent --add-service=http success [root@hawkeye ~]# firewall-cmd --permanent --add-port=10051/tcp success [root@hawkeye ~]# firewall-cmd --permanent --add-port=10050/tcp success [root@hawkeye ~]# firewall-cmd --reload success
Vamos desabilitar o SELinux dinamicamente:
[root@hawkeye ~]# setenforce permissive
E em seguida vamos alterá-lo no arquivo de configurações para que quando houver um novo boot ele não habilite novamente.
Para isto vamos alterar o parâmetro “SELINUX” no arquivo “/etc/selinux/config” para “permissive”:
[root@hawkeye ~]# vi /etc/selinux/config # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=permissive # SELINUXTYPE= can take one of three two values: # targeted - Targeted processes are protected, # minimum - Modification of targeted policy. Only selected processes are protected. # mls - Multi Level Security protection. SELINUXTYPE=targeted
Agora vamos habilitar o serviço do Zabbix Server para iniciar no boot:
[root@hawkeye ~]# systemctl enable zabbix-server
Em seguida iniciá-lo:
[root@hawkeye ~]# systemctl start zabbix-server
Verificamos se o serviço iniciou corretamente:
[root@hawkeye ~]# systemctl status zabbix-server

Como podemos ver acima, o serviço está “Active: active (running)”.
Vamos também habilitar o Zabbix Agent para iniciar automaticamente com o boot do servidor. Ele que fará a coleta dos dados do próprio Zabbix Server.
[root@hawkeye tmp]# systemctl enable zabbix-agent Created symlink from /etc/systemd/system/multi-user.target.wants/zabbix-agent.service to /usr/lib/systemd/system/zabbix-agent.service.
Agora iniciamos e verificamos se está executando corretamente:
[root@hawkeye tmp]# systemctl start zabbix-agent
[root@hawkeye tmp]# systemctl status zabbix-agent
