一、系统环境 操作系统：CentOS release 6.5 Squid版本：squid-3.1.10-20.el6_5.3.x86_64 SELINUX=disabled HTTP Service: stoped 二、安装Squid服务 2.1 检查squid软件是否安装 # rpm -qa|grep squid 2.2 如果未安装，则使用yum 方式安装 # yum -y install squid 2.3 设置开机自启动 # chkconfig --level 35 squid on //在3、5级别上自动运行squid服务 三、squid服务器的配置文件说明 squid 的主配置文件是 /etc/squid/squid.conf，所有squid的设定都是在这个文件里配置 http_port 3128 //设置监听的IP与端口号 cache_mem 64 MB //额外提供给squid使用的内存，squid的内存总占用为 X * 10+15+“cache_mem”，其中X为squid的cache占用的容量（以GB为单位）， //比如下面的cache大小是100M，即0.1GB，则内存总占用为0.1*10+15+64=80M，推荐大小为物理内存的1/3-1/2或更多。 maximum_object_size 4 MB //设置squid磁盘缓存最大文件，超过4M的文件不保存到硬盘 minimum_object_size 0 KB //设置squid磁盘缓存最小文件 maximum_object_size_in_memory 4096 KB //设置squid内存缓存最大文件，超过4M的文件不保存到内存 cache_dir ufs /var/spool/squid 100 16 256 //定义squid的cache存放路径 、cache目录容量（单位M）、一级缓存目录数量、二级缓存目录数量 logformat combined %>a %ui %un [%tl] "%rm %ru HTTP/%rv" %Hs %<st "%{Referer}>h" "%{User-Agent}>h" %ss:%sh //log文件日志格式 access_log /var/log/squid/access.log combined //log文件存放路径和日志格式 cache_log /var/log/squid/cache.log //设置缓存日志 logfile_rotate 60 //log轮循 60天 cache_swap_high 95 //cache目录使用量大于95%时，开始清理旧的 cachecache_swap_low 90 //cache目录清理到90%时停止。 acl localnet src 192.168.1.0/24 //定义本地网段 http_access allow localnet //允许本地网段使用 http_access deny all //拒绝所有 visible_hostname squid.david.dev //主机名 cache_mgr mchina_tang@qq.com //管理员邮箱 四、普通代理服务 4.1 编辑squid 主配置文件/etc/squid/squid.conf # # 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 # And finally deny all other access to this proxy http_access allow all # Squid normally listens to port 3128 http_port 3128 # We recommend you to use at least the following line. hierarchy_stoplist cgi-bin ? cache_mem 512 MB # Uncomment and adjust the following to add a disk cache directory. cache_dir ufs /var/spool/squid 20480 16 256 cache_log /var/log/squid/cache.log cache_access_log /var/log/squid/access.log cache_store_log /var/log/squid/store.log visible_hostname 192.168.3.34 cache_mgr ops@xuexibao.cn # 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 4.2 初始化 # squid –z 4.3 防火墙配置 用编辑器打开/etc/sysconfig/iptables ，添加开放端口 -A INPUT -m state --state NEW -m tcp -p tcp --dport 3128 -j ACCEPT [root@localhost ~]# service iptables restart 4.4启动Squid # /etc/init.d/squid start 五、在路由器中映射本机IP至端口的固定IP，测试代理服务 （编辑：甘南站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
