8. /usr/local/squid 쓰기 가능한지 체크 

구성

1. /usr/local/squid/etc/squid.conf 아래와 같이 대체
   (참조 : http://www.squid-cache.org/Versions/v3/3.0/cfgman/ )
   
   cache_store_log none

1. Replace all references of with the hostname of the server you wish to proxy.
2. Replace all references of with the port name that your jazz server listens upon.
3. Replace all references of with the hostname of your proxy machine.
4. Replace all references of with the port of your proxy machine.
5. Replace all references of with the amount of RAM that you want to allocate to squid's caching.  This must be less than the available memory on the machine. 
6. Replace all references of  in MBytes with the amount of diskspace you want ot allocate to squid.  This must be less than the available disk space in "/usr/local/squid/var/cache".

2. server.pem과 privkey.pem 파일을 /usr/local/squid/etc 아래로 복사
• 인증서 만들기
1. openssl req -new -keyform PEM -x509 -out server.pem
2. openssl rsa -in privkey.pem -out privkey.pem.new
3. cp privkey.pem.new privkey.pem
4. cp server.pem /usr/local/squid/etc/
5. cp privkey.pem /usr/local/squid/etc/
3. cd /usr/local/squid/sbin
4. 캐시 디렉토리(/usr/local/squid/var/cache) 구조화/초기화 실행 :
   
   @Ubuntu
   sudo touch /var/log/cache.log /var/log/access.log
   sudo chown proxy /var/log/cache.log /var/log/access.log
   @Ubuntu
   
   sudo su proxy
   ./squid -z(참조 : http://manpages.ubuntu.com/manpages/dapper/en/man8/squid.8.html )
5. 프락시서버 데몬 실행 :
   sudo ./squid

If things are not working properly, check the var/logs/cache.log for errors
you will see TCP_HIT and TCP_MISS logging in the access.log which will indicate whether or not the cache is being hit
