Linux下代理服务器配置

1.安装squid

[root@localhost ~]# yum install squid -y

安装:
  squid.x86_64 7:3.5.20-12.el7.x86_64.rpm                                                                                                      

依赖安装:
  libecap.x86_64 0:1.0.0-1.el7.x86_64.rpm
  perl-Digest-1.17-245.el7.noarch.rpm 
  perl-Digest-MD5-2.52-3.el7.x86_64.rpm    
  squid-migration-script-3.5.20-12.el7.x86_64.rpm

2.修改配置文件

[root@localhost ~]# vim /etc/squid/squid.conf
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

http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
http_access allow localhost manager
http_access deny manager
http_access allow localnet
http_access allow localhost
http_access deny all
http_port 3128

coredump_dir /var/spool/squid
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

主要是设置端口

http_access deny all
http_port 3128

3.启动服务

[root@localhost ~]# systemctl start squid

查看监听的端口：

[root@localhost cvechecker]# netstat -ntl 
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State      
tcp        0      0 0.0.0.0:3306            0.0.0.0:*               LISTEN     
tcp        0      0 0.0.0.0:111             0.0.0.0:*               LISTEN     
tcp        0      0 192.168.122.1:53        0.0.0.0:*               LISTEN     
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN     
tcp        0      0 127.0.0.1:631           0.0.0.0:*               LISTEN     
tcp        0      0 127.0.0.1:25            0.0.0.0:*               LISTEN     
tcp6       0      0 :::111                  :::*                    LISTEN     
tcp6       0      0 :::22                   :::*                    LISTEN     
tcp6       0      0 ::1:631                 :::*                    LISTEN     
tcp6       0      0 :::3128                 :::*                    LISTEN     
tcp6       0      0 ::1:25                  :::*                    LISTEN

可以看到3128端口已经启动

4.关闭防火墙

[root@localhost ~]# systemctl stop firewalld

5.客户端设置

在客户机终端输入：

export http_proxy=http://192.168.13.114:3128

这样就完成了代理，客户机就可以通过本机实现代理上网了
