ThunderCache - Desde a Instalação até a Configuração Final! Por BillGates
Vai ai mais uma dica,eu ja estava usando para testar e esta ok...
"Peguei com o colega ED"
Limpeza da memoria no proxy.
Abaixo segue o script e também um anexo do mesmo:
Código :
#!/bin/sh
#
# Salve este script no diretório /etc/cron.hourly e dê permissão
# de execução a ele. Desse modo a cada hora sera verificada se a
# porcentagem de memória utilizada pelo sistema atingiu o valor definido
# na variável 'percent'. Caso positivo, o script informará ao kernel
# que este deverá alterar o valor da opção 'drop_caches' para 3.
#
# Mais detalhes: 'man proc' -> /proc/sys/vm/drop_caches.
PATH="/bin:/usr/bin:/usr/local/bin"
# Porcentagem máxima de uso da memória, antes de executar a limpeza:
# Obs.: [B]Altere conforme sua necessidade[/B].
percent=[B]80[/B]
# Quantidade de memória RAM no sistema:
ramtotal=`grep -F "MemTotal:" < /proc/meminfo | awk '{print $2}'`
# Quantidade de RAM livre:
ramlivre=`grep -F "MemFree:" < /proc/meminfo | awk '{print $2}'`
# RAM utilizada pelo sistema:
ramusada=`expr $ramtotal - $ramlivre`
# Porcentagem de RAM utilizada pelo sistema:
putil=`expr $ramusada \* 100 / $ramtotal`
# Checando porcentagem:
if [ $putil -gt $percent ]
then
# Sincronizando os dados cacheados na memória com o(s) disco(s):
sync
# 'Dropando' cache:
echo 3 > /proc/sys/vm/drop_caches
else
# Remove-se as variáveis da memória e finaliza-se o script:
unset percent ramtotal ramlivre ramusada putil
exit $?
fi # Fim
Da forma como esta o script,de hora em hora ele ira rodar automaticamente,e caso a memoria estiver 80% ou mais em uso,ele ira limpar...
ThunderCache - Desde a Instalação até a Configuração Final! Por BillGates
Isso ai Arlin,vou começar agora um loadbalance usando o modo pcc,creio que poderiamos através do modo pcc configurar o seguinte cenário:
Ex:
5 Links
2 Links destinados a porta 80
1 Link destinado a ser default
1 Link destinado a redirecionar vídeos e outros
1 Link destinado a redireconar as portas https,messengers e outros
Entao 2 links seriam destinados a participar do modo pcc,ficando assim:
1º Cliente a conectar vai para o Link-1,2º Cliente a conectar vai para o Link-2,3º Cliente a conectar vai para o Link-1,4º Cliente a conectar vai para o Link-2 e assim por diante...
Dessa forma poderiamos balancear a carga de navegação (80).Para os que usam apenas links ADSL seria muito bom,pois o upload e conexões simultâneas seriam muito bem divididos.
E ainda teria links de apoio para segurar outros serviços...
Vou iniciar uns testes aqui,qualquer coisa posto os resultados mais tarde...
Instalando Sarg pra gerar relatorios do squid
Bom aproveitando pra terminar o tutorial acho que faltou falar do SARG que interpreta e gera relatorios do squid
pois como eu e muitos esta seguindo o belissimo tutorial do amigo bill gates fica aqui pra quem quiser gerar os relatorios do Squid assim como os do thunder que é gerado mediante IPproxy/thunder.conf e ver visualmente as economias dos arquivos então porque não ver as pagians gravadas pelo squid do mesmo geito IPproxy/squid-reports
bom vamos as configurações que são bem simples
apt-get update
apr-get install sarg
abra o sarg.conf que se encontra em /etc/squid/sarg.conf
e confirure desta forma

depois de instalado abra o com o squid.conf o do tutorial do bill gates que se encontra na pagina 3 e localize essas duas linhas #access_log /var/log/squid/access.log
#access_log /var/log/squid/error.log
e descomente as mesmas despois disso
de o comando squid -k reconfigure
feito isso pra ver os relatorios do SARG é só digitar o IPdoseuproxy/squid-reports ex. 192.168.6.2/squid-reports
