第一步、二步都是在能访问外网的机器上操作, 第三步是在不能访问外网机器上操作。
1、检查机器
在操作中发现访问外网的机器本身不能使用yum 安装软件,故需要配置yum安装源。如果可以的,这步可忽略。[root@localhost test]# lsb_release -a LSB Version: :core-4.0-amd64:core-4.0-ia32:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-ia32:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-ia32:printing-4.0-noarch Distributor ID: RedHatEnterpriseServer Description: Red Hat Enterprise Linux Server release 5.7 (Tikanga) Release: 5.7 Codename: Tikanga [root@localhost test]# cd /etc/yum.repos.d/ [root@localhost test]# wget http://mirrors.163.com/.help/CentOS5-Base-163.repo[/code]
中间 wget 所获取的文件,需要将$releasever 修改为 5# CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client. You should use this for CentOS updates # unless you are manually picking other mirrors. # # If the mirrorlist= does not work for you, as a fall back you can try the # remarked out baseurl= line instead. # # [base] name=CentOS-5 - Base - 163.com baseurl=http://mirrors.163.com/centos/5/os/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=os gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5 #released updates [updates] name=CentOS-5 - Updates - 163.com baseurl=http://mirrors.163.com/centos/5/updates/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=updates gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5 #packages used/produced in the build but not released [addons] name=CentOS-5 - Addons - 163.com baseurl=http://mirrors.163.com/centos/5/addons/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=addons gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5 #additional packages that may be useful [extras] name=CentOS-5 - Extras - 163.com baseurl=http://mirrors.163.com/centos/5/extras/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=extras gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-5 - Plus - 163.com baseurl=http://mirrors.163.com/centos/5/centosplus/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=centosplus gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5 #contrib - packages by Centos Users [contrib] name=CentOS-5 - Contrib - 163.com baseurl=http://mirrors.163.com/centos/5/contrib/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=contrib gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
yum clean all 清除原有缓存
yum list 获取yum列表
如果出现列表数据如下这种表示设置成功sqlite-devel.i386 3.3.6-7 base sqlite-devel.x86_64 3.3.6-7 base squashfs-tools.x86_64 3.0-4 base squirrelmail.noarch 1.4.8-21.el5.centos base srptools.x86_64 0.0.4-10.el5 base sssd.x86_64 1.5.1-70.el5 base sssd-client.i386 1.5.1-70.el5 base sssd-client.x86_64 1.5.1-70.el5 base sssd-tools.x86_64 1.5.1-70.el5 base2、安装squid
前面准备好yum命令, 可以直接在线安装yum install squid
安装完成后, cd /etc/squid/ 目下, 修改squid.conf 文件中的内容,修改之前, 可以先备份该文件:cp squid.conf squid.conf_bak
然后找到 文件中的 http_access deny all 将其修改为 http_access allow all 表示所有用户都可以访问这个代理,
还有找到 http_port 3128 修改为 http_port 192.168.3.171:3128 这里的IP及端口是 squid的代理IP及端口,
该IP是能访问外网机器的IP地址,如果是本机,则可以不用修改该地址, 下面启动squid 代理[root@localhost squid]# squid -k parse [root@localhost squid]# [root@localhost squid]# [root@localhost squid]# squid -z 2014/07/22 14:43:01| Creating Swap Directories [root@localhost squid]# [root@localhost squid]# [root@localhost squid]# service squid start Starting squid: [ OK ] [root@localhost squid]# [root@localhost squid]# [root@localhost squid]# [root@localhost squid]# netstat -nltp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN 4341/portmap tcp 0 0 0.0.0.0:3128 0.0.0.0:* LISTEN 22862/(squid) tcp 0 0 0.0.0.0:792 0.0.0.0:* LISTEN 4426/rpc.statd3、配置不能访问外网的机器代理
在其他有需要访问外网机器上设置其访问外部网络的代理机器export http_proxy=http://192.168.3.171:3128
这样就可以让不能访问外部网络的机器通过可以访问外网的机器做为代理访问到外部网络,来方便安装一些软件,
命令等操作。
