1，准备工作：Solaris10，squid-2.6.STABLE13
2，开始安装和配置：

1) 查看和修改最大连接数：
  #ulimit -a
core file size       (blocks, -c) unlimited
data seg size       (kbytes, -d) unlimited
file size          (blocks, -f) unlimited
open files                   (-n) 65536
pipe size       (512 bytes, -p) 10
stack size          (kbytes, -s) 8480
cpu time          (seconds, -t) unlimited
max user processes          (-u) 8485
virtual memory       (kbytes, -v) unlimited

修改：vi /usr/include/sys/types.h

#define FD_SETSIZE 10240
#ifndef _SYS_TYPES_H
#define _SYS_TYPES_H

2）将squid软件解压和安装到制定目录：
./configure --prefix=/usr/local/squid --disable-internal-dns --enable-useragent-log --enable-referer-log（可以看到连接数已经修改为10240）
make；make install；
3）在squid.conf文件里修改配置：
vi /usr/local/squid/etc/squid.conf

增加和修改的部分：
http_port 80 accel vhost
hierarchy_stoplist cgi-bin ?
acl QUERY urlpath_regex cgi-bin \?
cache deny QUERY
acl apache rep_header Server ^Apache
broken_vary_encoding allow apache
cache_mem 1024 MB
cache_dir ufs /export/home/squid/cache 4000 16 256
access_log /export/home/squid/logs/access.log squid
cache_log /export/home/squid/logs/cache.log
cache_store_log /export/home/squid/logs/store.log
pid_filename /export/home/squid/logs/squid.pid
cache_dns_program /usr/local/squid/libexec/dnsserver
dns_children 10
hosts_file /etc/hosts
refresh_pattern ^ftp:          1440 20%    10080
refresh_pattern ^gopher:       1440 0%    1440
refresh_pattern .jsp          0    20%    0

coredump_dir /export/home/squid/cache

4)配置hosts文件
#vi /etc/hosts
#
127.0.0.1    localhost
IP                www.abc.com

5）配置/etc/init.d/squid
#!/bin/bash
# squid       This shell script takes care of starting and stopping
#             Squid Internet Object Cache
#
# chkconfig: - 90 25
# description: Squid - Internet Object Cache. Internet object caching is \
#    a way to store requested Internet objects (i.e., data available \
#    via the HTTP, FTP, and gopher protocols) on a system closer to the \
#    requesting site than to the source. Web browsers can then use the \
#    local Squid cache as a proxy HTTP server, reducing access time as \
#    well as bandwidth consumption.
