Sobre o Ubuntu

Para começar a atualização do Ubuntu do sistema, primeiro precisamos atualizar a lista de índice de pacotes. Abra o terminal e digite:

sudo apt update

Podemos instalar a atualização para todos os pacotes de uma só vez: A forma a seguir vai atualizar todas as versões dos pacotes instalados, sem remover pacotes.

sudo apt upgrade

Tudo feito. Seu sistema Ubuntu agora está totalmente atualizado.

Durante a atualização inicial do sistema, alguns dos pacotes podem se tornar obsoletos e, portanto, não são mais necessários. Para remover todos os pacotes desnecessários, execute:

sudo apt autoremove

Para analise do Kernel


Para analise da Bios

sudo dmidecode -t bios

UFW ( Uncomplicated Firewall ) é um firewall padrão no Ubuntu 18.04 Bionic Beaver Linux.

Por padrão, o UFW está desativado. Você pode verificar o status do seu firewall executando o seguinte comando:

sudo ufw status

Para habilitar a execução do firewall:

sudo ufw enable

Visualizar erros do servidor

No terminal pode ser o comando para a visualização do log de erro do servidor

tail -f /var/log/apache2/error.log


telnet 3306 # mysql

telnet localhost 27017 # mongodb

curl --connect-timeout 10 --silent --show-error

Monitorando MySQL

Na necessidade de acessar o MySQL Client e ver os processos

mysql -h '' -u root -p

show processlist;

ou melhor ainda

mysqladmin -u root -p -i 1 processlist

mysql config

mysql -h '' -P '3306' -u 'root' -p'12345' -e "SHOW GLOBAL VARIABLES LIKE 'innodb_buffer_pool_size';"

mysql --help

sudo echo "innodb_buffer_pool_size = 8M" >> /etc/mysql/mysql.conf.d/mysqld.cnf

sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf

cat /etc/mysql/mysql.conf.d/mysqld.cnf

sudo systemctl status mysql
sudo systemctl restart mysql

mysql -h '' -P '3306' -u 'root' -p'12345' -e "SHOW GLOBAL VARIABLES LIKE 'innodb_buffer_pool_size';"

Recursively fix bad file permissions

A common suggestion is to use which means:

755 for directories: full control for the user, and everyone else can traverse directories.

644 for files: read-write permissions for the user, and read-only for everyone else.
