Berikut ini adalah beberapa perintah yang dapat Anda lakukan untuk melihat performansi squid proxy server anda. Perintah ini dapat anda buat dalam bentuk file berextensi ".sh" dan letakkan di direktori /usr/sbin, sehingga anda tidak perlu menghapalkan syntax2 tersebut. Cukup membantu untuk para network administrator atau teknisi.

1. Perintah pertama

squidclient -h localhost -p 8080 mgr:info

Sesuaikan port 8080 dengan port squid Anda.
Hasilnya:

    HTTP/1.0 200 OK

Selamat Mencoba Dan Semoga Berhasil :D 

Oke kali ini, sesuai judul, saya mau posting sdikit informasi, tentang Perbedaan Squid dan Lusca, Oke. Berikut kira-kira perbedaan berdasarkan beberapa jenis.

Berdasarkan Package nya, Perbedaannya adalah:

    lusca : menggunakan perl versi perl squid v.perl-5.12.3 Lusca perl-5.10.1.
    squid : menggunakan ldap  sedangkan lusca tidak menggunakan

Nah berdasarkan kelebihan dan kekurangannya:

    squid : Termnasuk masih bahan mentah kalau untuk cache proxy, belum di tunning dsb.
    Lusca : kalo buat cache lusca sudah berbentuk barang jadi artinya tinggal pakai langsung jalan, Atau bisa disebut juga versi modding dari squid itu sendiri

Sedikit informasi saja, mungkin dari sobat ada yang ingin menambahkan, silahkan postkan di komentar di bawah ini. Terima Kasih. Semoga Bermanfaat.

Squid LUSCA adalah squid yang mampu menyimpan cache video selain menyimpan cache web biasa. Setelah anda menginstal ubuntu server, langkah selanjutnya adalah dengan mengupgrade ubuntu kita dan menginstal squid+LUSCA.

Setelah login ke ubuntu server dengan memakai hak akses login dan pasword admin anda, kita masuk ke direktori root dengan mengetikan :

#sudo su

kemudian masukan kembali username dan pasword anda. setelah masuk ke root directori, selanjutnya ikuti langkah-langkah berikut dengan mengetikan di console ubuntu anda.

# sudo apt-get update
# sudo apt-get install squid
# sudo apt-get install squid squidclient squid-cgi
# sudo apt-get install gcc
# sudo apt-get install build-essential
# sudo apt-get install sharutils
# sudo apt-get install ccze
# sudo apt-get install libzip-dev
# sudo apt-get install automake1.9

Mungkin membutuhkan banyak waktu sampai update dan proses instal diatas selesai, dan tergantung kecepatan internet anda.
Setelah proses selesai kemudian download LUSCA dengan cara mengetikan di console ubuntu anda :

#wget http://lusca-cache.googlecode.com/files/LUSCA_HEAD-r14756.tar.gz

Extract LUSCA yang telah di download tadi :

#tar xvf LUSCA_HEAD-r14756.tar.gz

Masuk ke direktori LUSCA :

#cd LUSCA_HEAD-r14756

Sebelum mengompile LUSCA, lakukan perintah dibawah ini :

#./bootstrap.sh

Mengompile LUSCA, copas perintah dibawah ini :

./configure --prefix=/usr --exec_prefix=/usr --bindir=/usr/sbin --sbindir=/usr/sbin --libexecdir=/usr/lib/squid
--sysconfdir=/etc/squid \
--localstatedir=/var/spool/squid --datadir=/usr/share/squid --enable-http-gzip --enable-async-io=24 --with-aufs-threads=24
--with-pthreads --enable-storeio=aufs \
--enable-linux-netfilter --enable-arp-acl --enable-epoll --enable-removal-policies=heap --with-aio --with-dl --enable-snmp \
--enable-delay-pools --enable-htcp --enable-cache-digests --disable-unlinkd --enable-large-cache-files --with-large-files \
--enable-err-languages=English --enable-default-err-language=English --with-maxfd=65536

Setelah proses compile selesai, lakukan peritah dibawah :

# make
# make install

Setelah proses diatas selesai, berarti anda sudah berhasil menginstal squid+LUSCA di ubuntu server anda. tetapi sebelum mengaktifkan squid lusca anda, ada hal-hal yang harus di edit:

1. Copy squid.conf dan storeurl.pl ke folder /etc/squid dalam ubuntu server anda.
2. Edit squid.conf dan sesuaikan dengan jaringan anda
3. edit Aufs di file squid.conf anda

Dalam mengupload atau mengcopikan file squid.conf dan mengeditnya, ada berbagai cara diantaranya yaitu dengan cara remote ubuntu kita dengan memakai winscp dan putty. Supaya file-file dalam folder /etc/squid di ubuntu anda bisa di copas dan di edit, kita harus memberikan permission dulu pada folder dan file tersebut stop dulu squid anda dengan cara :

#sudo /etc/init.d/squid stop

Berikan permision pada folder dan file di /etc/squid :

#chmod 777 /etc/squid
#chmod 777 /etc/squid/squid.conf
#chmod 777 /etc/squid/storeurl.pl

Selanjutnya copas file-file yang dibutuhkan yang telah di download tadi kedalam folder /etc/squid yang ada didalam ubuntu server anda kemudian edit squid.conf dan sesuaikan dengan jaringan anda. Jangan lupa edit juga aufs yang ada di squid.conf. perhitungan ufs disesuaikan dengan besarnya ukuran masing-masing cache yang anda gunakan. cara perhitungan aufs adalah :

(((x / y) / 256) / 256) * 2
x=besarnya partisi untuk /cache dalam KB
z=Number of directories per first level directory

Contoh :

Apabila cache kita berukuran 30Gb=30000000Kb
30,000,000 / 13 = 2307692.3 / 256 = 19014.5 / 256 = 35.2 * 2 = 70
Jadi angka buat L1nya adalah 70. berarti setingan aufs pada squid.conf anda adalah :

cache_dir aufs 30000 70 256

Setelah selesai mengedit squid.conf langkah selanjutnya adalah memberikan permission kepada partisi hardisk cache yang kita pakai, yaitu dengan cara:

#chown proxy:proxy /cache1
#chown proxy:proxy /cache2
#chown proxy:proxy /cache3
#chown proxy:proxy /var/log/squid/access.log
#chown proxy:proxy /etc/squid/storeurl.pl
#chmod 777 /cache1
#chmod 777 /cache2
#chmod 777 /cache3
#squid -f /etc/squid/squid.conf –z

Restart squid ada

#sudo /etc/init.d/squid restart

Kemudian PC sobat :

#reboot
