我已经在我的 centos vps 服务器上设置了 squid，并且我尝试通过我的 windows 计算机连接到它，但是我在所有网站上都收到以下错误：
等待 google.com
代理服务器没有响应
我按照以下教程设置了 squid：
我的 squid 配置文件：
#
# Recommended minimum configuration:
#
acl manager proto cache_object
acl localhost src 127.0.0.1/32 ::1
acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1
# 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 SSL_ports port 443
acl Safe_ports port 80 # http
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 488 # gss-http
acl Safe_ports port 591 # filemaker
acl Safe_ports port 777 # multiling http
acl CONNECT method CONNECT
#
# Recommended minimum Access Permission configuration:
#
# Only allow cachemgr access from localhost
http_access allow manager localhost
http_access deny manager
# Deny requests to certain unsafe ports
http_access deny !Safe_ports
# Deny CONNECT to other than secure SSL ports
http_access deny CONNECT !SSL_ports
# 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 localnet
http_access allow localhost
http_access allow all
# And finally deny all other access to this proxy
# http_access deny all
# Squid normally listens to port 3128
http_port 3128
# We recommend you to use at least the following line.
hierarchy_stoplist cgi-bin ?
# 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
visible_hostname myproxy
谢谢。

netstat -nltap | grep LIS 输出：
tcp 0 0 0.0.0.0:22 0.0.0.0:* ESTABLISHED 1112/sshd
tcp 0 0 :::22 :::* LISTEN 933/sshd
tcp 0 0 :::3128 :::* LISTEN 1279/(squid)
tcp 0 0 ::1:25 :::* LISTEN 1010/master
答案1
除了日志之外，还要检查其他一些东西
- 本地防火墙（iptables）
- squid 是否正在监听其他服务器可以访问的外部 IP？
netstat -nltap | grep LIS - （如 1），使用 nc 或 telnet 验证您是否可以从客户端访问默认值
squid port 3128。telnet squidserver 3128，有任何回应吗？
答案2
如果端口被阻止：
iptables -I INPUT -p tcp -m state --state NEW -m tcp --dport 3128 -j ACCEPT
iptables-save > /etc/sysconfig/iptables
我从 Bitrix Virtual Appliance 中得到了这个想法：
