[b:08a74b3ab3]首先升级openssl（为了系统更安全）[/b:08a74b3ab3]

[b:08a74b3ab3]修改src/fs/aufs/store_asyncufs.h，使其可以用异步IO写文件，以提高存储速度
将#define ASYNC_WRITE改为1[/b:08a74b3ab3]

make

make install

[b:08a74b3ab3]进入helpers/basic_auth/NCSA，编译出nasa_auth[/b:08a74b3ab3]

[b:08a74b3ab3]创建交换文件[/b:08a74b3ab3]

useradd squid -s /sbin/nologin

mkdir -p /usr/local/squid/var/cache

chown -R squid.squid /usr/local/squid/var

/usr/local/squid/sbin/squid -z

[b:08a74b3ab3]运行squid[/b:08a74b3ab3]

/usr/local/squid/sbin/squid

若使开机自动运行，在/etc/rc.local里添加即可

ljily000 回复于：2005-03-13 12:54:28对每个用户能否绑定一个ip，该用户只能在指定ip的机器上通过squid代理出去。

platinum 回复于：2005-03-13 14:00:35可以用acl控制
也可以结合iptables来实现

wingger 回复于：2005-03-13 18:14:42External ACLs

squid2.5版本，有一个ACL扩展功能ip_user，应该可以满足你的要求

如：可能安装的时候要编译进去
[code:1:2707935133]./configure —enable-external-acl-helpers=ip_user[/code:1:2707935133]

配置时要在squid.conf加入如下一行:

[code:1:2707935133]external_acl_type ip_user_helper %SRC %LOGIN

usr/local/squid/libexec/ip_user -f /usr/local/squid/etc/ip_user.conf

acl AclName external ip_user_helper[/code:1:2707935133]

%SRC 指客户IP地址，%LOGIN指用户名. 在ip_user.conf 中的配置格式如下:

ip_addr[/mask] user|@group|ALL|NONE

例如:

[code:1:2707935133]127.0.0.1 ALL

192.168.1.0/24 bob

10.8.1.0/24  @lusers

172.16.0.0/16  NONE[/code:1:2707935133]

上面的语句意思如下（我就不翻译了）：
This configuration file causes ip_user to return OK for any request coming from 127.0.0.1, for Bob's requests coming from the 192.168.1.0/24 network, for any name in the luser group when the request comes from the 10.8.1.0/24 network, and returns ERR for any request from the 172.16.0.0/16 network. It also returns ERR for any address and username pair that doesn't appear in the list.

:P  :P
[code:1:c478550dd1][code]external_acl_type ip_user_helper %SRC %LOGIN

usr/local/squid/libexec/ip_user -f /usr/local/squid/etc/ip_user.conf

acl AclName external ip_user_helper [/code][/code:1:c478550dd1]

好像差点东西 :P ，

[code:1:c478550dd1]external_acl_type ip_user_helper %SRC %LOGIN
/usr/local/squid/libexec/ip_user_check -f /usr/local/squid/etc/ip_user.conf
acl AclName external ip_user_helper [/code:1:c478550dd1]

找了好半天！ :em06:
