內(nèi)外網(wǎng)環(huán)境，做了網(wǎng)絡(luò)隔離，只有一臺機器能夠訪問外網(wǎng)。
故在該機器上配置代理服務(wù)器，進(jìn)行代理轉(zhuǎn)發(fā)。
之前使用Nginx,但是發(fā)現(xiàn)nginx支持不了https的請求 (強行支持也行，需要裝一些額外包，源碼編譯，沒必要折騰）

這里記錄下一個Squid的快速配置安裝

安裝

可以采用多種方式安裝。裝好后，一般在/usr/sbin/squid 默認(rèn)配置文件是：/etc/squid/squid.conf

yum install squid

修改配置文件

如果沒有root權(quán)限，建議就在自己的目錄建一個squid.conf
copy一個下面的demo。 （這個是從默認(rèn)的/etc/squid/squid.conf里面復(fù)制出來的。）

一般情況下只需要修改下，
服務(wù)端口 http_port： 10000
日志文件路徑之類的。

如果沒有root權(quán)限，記得把里面的log路徑，pid路徑修改下。

#
# Recommended minimum configuration:
#

# Squid normally listens to port 3128
http_port 10000  

# 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:
#
# 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

# 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 localnet
http_access allow localhost

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



# 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
cache_mem 32 MB
cache_dir aufs /home/wxadmin/app/squid/cache/ 1024 16 256
access_log /home/wxadmin/app/squid/log/access.log
cache_log  /home/wxadmin/app/squid/log/cache.log
pid_filename /home/wxadmin/app/squid/squid.pid

#
# 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

初始化/啟動/停止

squid需要進(jìn)行初始化才能使用。
-f 參數(shù)指定自定義配置文件。
一些常用命令。

#初始化
/usr/sbin/squid -f /home/wxadmin/app/squid/squid.conf -z
# 開始
/usr/sbin/squid -f /home/wxadmin/app/squid/squid.conf start
# 重啟
/usr/sbin/squid -f /home/wxadmin/app/squid/squid.conf restart
# 關(guān)閉
/usr/sbin/squid -f /home/wxadmin/app/squid/squid.conf -k shutdown

檢查

檢查端口,是否10000端口在服務(wù)。

netstat -lnp

檢查是否配置成功

curl -x 127.0.0.1:10000 https://www.baidu.com
