一般出于安全考慮批狱，服務(wù)器組都是只有一臺(tái)服務(wù)器能訪問外網(wǎng)裸准，其他都是以內(nèi)網(wǎng)的形式連接。
如果我們要給內(nèi)網(wǎng)的機(jī)器安裝東西這時(shí)候由于無法訪問到外網(wǎng)而導(dǎo)致失敗赔硫。這時(shí)候我們就需要把能訪問外網(wǎng)的機(jī)器部署成代理服務(wù)器狼速。

一 安裝部署squid
- yum install squid
- cd /etc/squid/
- 備份文件 cp squid.conf squid.conf_bak 備份文件
- 修改 把
http_access deny all修改為http_access allow all

# 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 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 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
#這里把 http_access deny all 修改為 http_access allow all
http_access allow all
# Squid normally listens to port 3128
http_port 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
- 啟動(dòng)squid
squid -k parse
squid -z
service squid start
- 查看squid服務(wù)
netstat -tupln | grep squid
- 查看本機(jī)地址

本地內(nèi)網(wǎng)地址是 192.168.100.3
二 配置內(nèi)網(wǎng)機(jī)器
- 配置臨時(shí)代理地址（重新登錄失效）
export http_proxy="http://192.168.100.3:3128"
- 配置yum代理地址
vi /etc/yum.conf
增加 proxy=http://192.168.100.3:3128
[main]
#配置yum的代理地址。
proxy=http://192.168.100.3:3128
cachedir=/var/cache/yum/$basearch/$releasever
keepcache=0
debuglevel=2
logfile=/var/log/yum.log

# This is the default, if you make this bigger yum won't see if the metadata
# is newer on the remote and so you'll "gain" the bandwidth of not having to
# download the new metadata and "pay" for it by yum not having correct
# information.
# It is esp. important, to have correct metadata, for distributions like
# Fedora which don't keep old packages around. If you don't like this checking
# interupting your command line usage, it's much better to have something
# manually check the metadata once an hour (yum-updatesd will do this).
# metadata_expire=90m
# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d
下面我們就能愉快的安裝各種軟件啦卦停。向胡。。
yum install gcc
yum install cmake
