SETTING CACHE SQUID

SETTING CACHE SQUID


Membuat cache dan perhitungan CACHE squid di linux

Cache direktory bisa di buat dengan cara membuat direktori langsung pada partisi yg ada,bisa jg dibuat dengan cara membuat 1 partisi tersendiri untuk cache tersebut.
Buat dengan cara berikut :

1. Masuk ke terminal->pindah ke mode super users->ENTER
2. setelah itu pidah direktory ke root ( / )
3. ketik mkdir cache1->Enter
4. lalu ubah permision file chmod 777 -R cache1
5. lalu lakukan editing pada squid anda : pico /etc/squid/squid.conf
6. Lakukan Perhitungan cache seperti dibawah ini :
1. Gunakan 80% atau kurang dari setiap kapasitas cache direktori
yang telah kita siapkan. Jika kita mengeset ukuran cache_dir
melebihi nilai ini, maka kita akan dapat melihat penurunan performansi squid.
2. Untuk menentukan jumlah subdirektori pertama yang akan dibuat,
dapat menggunakan rumus ini:
x= Ukuran cache dir dalam KB (misal 6GB=~6,000,000KB)
y= Average object size (gunakan saja 13KB)
z= Jumlah subdirektori pertama = (((x / y) / 256) / 256) * 2 = # direktori
Sebagai contoh, misal saya menggunakan 6 GB dari untuk /cache
(setelah disisihkan 80% nya), maka:
6,000,000 / 13 = 461538.5 / 256 = 1802.9 / 256 = 7 * 2 = 14
maka baris cache_dir akan menjadi seperti ini: cache_dir ufs 6000 14 256
9,000,000 / 13 = 461538.5 / 256 = 2704.3 / 256 = 10.56 * 2 = ~ 22
maka baris cache_dir akan menjadi seperti ini: cache_dir ufs 9000 22 256
12,000,000 / 13 = 923077 / 256 = 3605.8 / 256 = 14.08 * 2 = ~ 28
maka baris cache_dir akan menjadi seperti ini: cache_dir ufs 12000 28 256

Cara Install Squid Proxy Server di Ubuntu Server 10.10 dan 10.04

Cara Install Squid Proxy Server di Ubuntu Server 10.10 dan 10.04

Saya anggap anda sudah paham cara install ubuntu server 10.10 atau 10.04.

Berikut konfigurasi partisi harddisk di ubuntu server dengan ukuran HDD 80GB:
1. /boot -----> 1Gb ext4 Boot Flag on
2. / ------> 3Gb ext4
3. /usr -----> 5Gb ext4
4. /var -----> 5Gb ext4
5. swap -----> 2Gb (2 x RAM di PC)
6. /cache -----> 50Gb ReiserFS (intel) atau BTRFS (AMD)
7. /home ------> sisanya jika ada

Langka-langkah:
1. Login ubuntu dengan putty
2. Jika belum membuat user root, ketik "sudo su", masukkan password ubuntu kamu, kemudian ketik "passwd" dan isikan password baru untuk root.
3. Silahkan copas sintak di bawah melalui putty:
sudo apt-get update
sudo apt-get install squid
sudo apt-get install squid squidclient squid-cgi
sudo apt-get install ccze
4. Stop squid-nya dengan perintah:
"squid stop" atau "/etc/init.d/squid stop" atau "service squid stop" jika tidak mau restart dulu PC-nya.
5. Edit squid.conf memakai winscp atau dengan perintah:
nano /etc/squid/squid.conf
Kemudian Copy-Paste isi squid.conf di bawah ini (sebelumnya backup dulu squid.conf yang asli:

 Kode di atas lebih baik copy dulu ke notepad.

6. Stop lagi squid-nya dengan perintah:
"squid stop" atau "/etc/init.d/squid stop" atau "service squid stop" jika tidak mau restart dulu PC-nya.
7. Memberikan permission, ketik pada putty:
chown -R proxy.proxy /cache
chown proxy.proxy /var/log/squid/access.log 
8. Membuat swap, ketik pada putty:
squid -f /etc/squid/squid.conf -z
atau
squid -z
 9. Restart squid-nya:
"squid restart" atau "service squid restart" atau "/etc/init.d/squid restart", jika tidak bisa restart PC-nya.
10. Buka www.whatismyip.com, jika berhasil akan tertera keterangan IP public dengan proxy detected squid 2.7 stable.

Semoga anda bisa dan berhasil. Selamat mencoba.
