文章總結了作者在配置系統(tǒng)服務時的個人經(jīng)驗,包括生成密碼文件、測試密碼文件配置、啟動服務、配置副本（包括無權限控制和權限控制）等步驟,并鼓勵讀者參考和使用腳本之家

安裝

yum install squid -y
yum install httpd-tools -y

生成密碼文件

mkdir /etc/squid3/
#這里密碼是 ceshi 
htpasswd -cd /etc/squid3/passwords ceshi
#回車 自己輸入密碼

測試密碼文件

/usr/lib64/squid/basic_ncsa_auth /etc/squid3/passwords
#輸入賬號跟密碼
ceshi 123456
#提示 OK 代表正確
OK

配置

vim /etc/squid/squid.conf

# 在最后添加

auth_param basic program /usr/lib64/squid/basic_ncsa_auth /etc/squid3/passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated

# 這里是端口號，可以按需修改
# http_port 3128 這樣寫會同時監(jiān)聽ipv6和ipv4的端口，推薦適應下面的配置方法。
http_port 0.0.0.0:3128

啟動服務

# 開啟啟動
systemctl enable squid.service
# 啟動
systemctl start squid.service
# 停止
systemctl stop squid.service
# 重啟
systemctl restart squid.service

配置副本–無權限控制

#
# Recommended minimum configuration:
#

# Example rule allowing access from your local networks.
# Adapt to list your (internal) IP networks from where browsing
# should be allowed
acl localnet src 10.0.0.0/8	# RFC1918 possible internal network
acl localnet src 172.16.0.0/12	# RFC1918 possible internal network
acl localnet src 192.168.0.0/16	# RFC1918 possible internal network
acl localnet src fc00::/7       # RFC 4193 local private network range
acl localnet src fe80::/10      # RFC 4291 link-local (directly plugged) machines

acl Safe_ports port 21		# ftp
acl Safe_ports port 443		# https
acl Safe_ports port 70		# gopher
acl Safe_ports port 210		# wais
acl Safe_ports port 1025-65535	# unregistered ports
acl Safe_ports port 280		# http-mgmt

acl Safe_ports port 591		# filemaker
acl Safe_ports port 777		# multiling http
#acl many_spaces rep_header Disposition -i [k123]
acl CONNECT method CONNECT

#
# Recommended minimum Access Permission configuration:
#
# Deny requests to certain unsafe ports
#http_access allow all !Safe_ports

# Deny CONNECT to other than secure SSL ports
#http_access deny CONNECT !SSL_ports

# Only allow cachemgr access from localhost
http_access allow localhost manager
http_access deny manager

# We strongly recommend the following be uncommented to protect innocent
# web applications running on the proxy server who think the only
# one who can access services on "localhost" is a local user
#http_access deny to_localhost

#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#

# Example rule allowing access from your local networks.
# Adapt localnet in the ACL section to list your (internal) IP networks
# from where browsing should be allowed
#http_access allow all
http_access allow all

auth_param basic program /usr/lib64/squid/basic_ncsa_auth /etc/squid3/passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
#http_access allow authenticated

# And finally deny all other access to this proxy
http_access allow all

# Squid normally listens to port 3128
http_port 0.0.0.0:3128

# Uncomment and adjust the following to add a disk cache directory.
#cache_dir ufs /var/spool/squid 100 16 256

# Leave coredumps in the first cache dir
coredump_dir /var/spool/squid

#
# Add any of your own refresh_pattern entries above these.
#
refresh_pattern ^ftp:		1440	20%	10080
refresh_pattern ^gopher:	1440	0%	1440
refresh_pattern -i (/cgi-bin/|\?) 0	0%	0
refresh_pattern .		0	20%	4320
