所以選用centos 7 來架設 Squid Proxy 正向代理的服務
需求:
(a)允許 https 的 SSL Proxy 功能
(b)假設指定只有 來自 11.11.22.22/32 與 11.11.11.0/24 的 IP 範圍才可以使用,不在IP白名單的使用密碼驗證
(c)隱藏使用者真實IP
(一)安裝步驟:
# yum install -y squid httpd-tools
(二)備份原squid.conf檔,並且貼上以下所有內容取代原本的
# mv /etc/squid/squid.conf /etc/squid/squid.conf.bak
# vi /etc/squid/squid.conf
QUOTE:
# Example rule allowing access from your local networks.(三) 建立密碼檔
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 squid_user proxy_auth REQUIRE

via off
follow_x_forwarded_for deny all
request_header_access X-Forwarded-For deny all
# And finally deny all other access to this proxy
#http_access deny all
http_access allow all
第一次建立帳號 =>
# mkdir /etc/squid/auth/
# htpasswd -c /etc/squid/auth/passwd adj
之後建立帳號或修改密碼
# htpasswd /etc/squid/auth/passwd adj2
第一次啟動與設定自動啟動
# systemctl restart squid.service
# systemctl enable squid.service
(四)驗證測試
外部測試方式:
# curl --proxy proxy.adj.com.tw:3128 https://www.google.com
外部測試方式(需要帳密的情況下):
# curl -U adj:adj --proxy proxy.adj.com.tw:3128 ifconfig.me
這樣就可以囉~~
