Squid (PROXYサーバ)を動かしてみる
Modified: 15 Jun 2001
"/etc/squid/squid.conf" の変更
最低限、赤いところ（４個所）変更します。
# WELCOME TO SQUID 2
# ------------------
#
# This is the default Squid configuration file. You may wish
# to look at http://cache.is.co.za/squid/ for documentation,
# or the Squid home page (http://squid.nlanr.net/) for the FAQ.
#
# The default Squid config file shows what the defaults for
# various options happen to be. If you don't need to change the
# default, you shouldn't uncomment the line. Doing so may cause
# run-time problems. In some cases "none" refers to no default
# setting at all, whilst in other cases it refers to a valid
# option - the comments for that keyword indicate if this is the
# case.
#
# NETWORK OPTIONS
# ---------------------------------------------------
# TAG: http_port
# The port number where Squid will listen for HTTP client
# requests. Default is 3128, for httpd-accel mode use port 80.
# May be overridden with -a on the command line.
#
# You may specify multiple ports here, but they MUST all be on
# a single line.
#
http_port 3128コメントアウト

# LOGFILE PATHNAMES AND CACHE DIRECTORIES
# ---------------------------------------------------
# TAG: cache_dir
# Usage:
#
# cache_dir Directory-Name Mbytes Level-1 Level2
#
# You can specify multiple cache_dir lines to spread the
# cache among different disk partitions.
#
# 'Directory' is a top-level directory where cache swap
# files will be stored. If you want to use an entire disk
# for caching, then this can be the mount-point directory.
# The directory must exist and be writable by the Squid
# process. Squid will NOT create this directory for you.
#
# If no 'cache_dir' lines are specified, the following
# default will be used: /usr/local/squid/cache.
#
# 'Mbytes' is the amount of disk space (MB) to use under this
# directory. The default is 100 MB. Change this to suit your
# configuration.
#
# 'Level-1' is the number of first-level subdirectories which
# will be created under the 'Directory'. The default is 16.
#
# 'Level-2' is the number of second-level subdirectories which
# will be created under each first-level directory. The default
# is 256.
#
cache_dir ufs /var/spool/squid/cache 100 16 256（（（途中略）））
# TAG: http_access
# Allowing or Denying access based on defined access lists
#
# Access to the HTTP port:
# http_access allow|deny [!]aclname ...
#
# Access to the ICP port:
# icp_access allow|deny [!]aclname ...
#
# NOTE on default values:
#
# If there are no "access" lines present, the default is to allow
# the request.
#
# If none of the "access" lines cause a match, the default is the
# opposite of the last line in the list. If the last line was
# deny, then the default is allow. Conversely, if the last line
# is allow, the default will be deny. For these reasons, it is a
# good idea to have an "deny all" or "allow all" entry at the end
# of your access lists to avoid potential confusion.
#
#Default configuration:
#http_access allow manager localhost
http_access allow all
http_access deny manager
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#
#http_access deny all（（（途中略）））
# ADMINISTRATIVE PARAMETERS
# ----------------------------------------------------
# TAG: cache_mgr
# Email-address of local cache manager who will receive
# mail if the cache dies. The default is "webmaster."
#
#cache_mgr webmaster
# TAG: cache_effective_user
# TAG: cache_effective_group
#
# If the cache is run as root, it will change its effective/real
# UID/GID to the UID/GID specified below. The default is to
# change to UID to nobody and GID to nogroup.
#
# If Squid is not started as root, the default is to keep the
# current UID/GID. Note that if Squid is not started as root then
# you cannot set http_port to a value lower than 1024.
#
cache_effective_user squid
cache_effective_group squid（（（途中略）））
初期化処理をする
# /usr/sbin/squid -z

#"squid.conf" の、"cache_dir" で設定したディレクトリ（/usr/local/squid/cache）の下に、"00", "01", "02", "03", "04", "05", "06", "07", "08", "09", "0A", "0B", "0C", "0D", "0E", "0F" が作られます。
作られたディレクトリの、ユーザ/グループは、nobody/nobody となっています。
"linuxconf" で設定します。
「編集」、「設定」を選択し、以下のように、「詳細」、「プロキシ」を選択し、「手動でプロキシを設定する」にチェックをいれ、「表示」ボタンを押します。
