Cara menghapus cache proxy  

Proxy sebenarnya memiliki mekanisme otomatis untuk penghapusan cache nya jika penuh, tapi suatu saat mungkin dibutuhkan penghapusan cache proxy secara manual, biasanya karena untuk perubahan volume cache oleh admin, atau proxy macet karena ada bad packet yang keburu di cache dan lengket disana.
hal ini akan terasa bila yang mengaksek proxy banyak atau ketika user full (klo diwarnet) akan terasa berat, malah bisa dibilang akses internet lebih cepat tanpa proxy, dan kalo diliah di lognya wadaw banyak banget errornya.
untuk itu makanya sesuatu bangeut (kata syahrini)....

sebenernya sih bisa  singkat penjelasannya, namun inikan untuk pemula jd hanya untuk pemula yang pengennya di tampilkan secara screen shot. (ini yg buat ane males, pake gambar lagi)
cekidot gan......
sebelumnya ane praktek di mesin freebsd. jd configurasi tiap mesin beda yach, syukur klo sama tinggal di copas mentah" (klo bisa pelajari dulu yach, sesuaikan saja).
1. siapkan tool putty dan winscp, klo bisa.  masuk deh sebagai root baik putty maupun winscp
2. matikan squidnya (caranya gimana yach)




3. hapus direktori cache, sesuaikan di conf.inf, contoh posisi ane di     
    /usr/local/etc/squid/squid.conf
 buka file squid.conf anda cari isinya yang seperti ini (pasti beda donk dgn anda)














posisi cachenya ada di  /cache-1 
jadi perintah hapusnya rm –rf /cache-* 

lumayan agak lama yach cache sebesar 25 Giga dihapus menghabiskan waktu 30 menit di mesin p4 celeron dgn memori 1 Giga. krik krik krik..... sing sabar....

nah klo situ mau rubah direktori jadi /cache-2 maka selain dirubah di squid.conf juga dibuat kepemilikannya, caranya gini    
# chown -R proxy:proxy /cache-*  (sekalian ajah ha ha ha pasti binggung).

hapus juga access.log dan cache.log (nanti buat yg baru)
biar gampang buat dulu access.log dan cache.log secara manual (nanti rename lalu buat kepemilikannya jd proxy )<---- ini pake winscp ya.

cara menghapusnya rm –rf /var/log/squid/access.log
cara menghapusnya rm –rf /var/log/squid/cache.log

bila buat lagi file nya di console menjadi (pake putty ini)
touch /var/log/squid/access.log
touch /var/log/squid/cache.log
lalu ubah kepemilikanna
# chown -R proxy:proxy /var/log/squid/*

4. klo udah selesai, kasih perintah" lagi
# squid -z  <= membuat swap squid
# squid -k parse  <= cek konfig squid
# squid -DF         <= perintah menjalankan squid atau
# /usr/local/etc/rc.d/squid.sh start
# sockstat -4      <= perintah untuk melihat berjalan atau tidaknya squid


coba browsing semoga jalan proxynya................... pasti enteng lagi tuh proxy.

di mohon untuk tidak ditelan bulat" copasnya, di coba dan dipelajari.

have nice day
