1、编译源码

# tar -zxf squid-3.5.23.tar.gz

# cd squid-3.5.23

# ./configure --prefix=/usr/local/squid

# make && make install

2、编辑配置文件

/usr/local/squid/etc # cat squid.conf | grep -v "^#" | grep -v "^$"

cache_peer 192.168.1.100 parent 8099 0 no-query

http_access allow all

never_direct allow all

http_access allow all

http_port 3128

cache_dir ufs /usr/local/squid/var/cache/squid 100 16 256

cache_access_log /usr/local/squid/var/logs/access.log

cache_log /var/squid/cache.log

coredump_dir /usr/local/squid/var/cache/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

配置说明：

cache_peer 192.168.1.100 parent 8099 0 no-query # 配置的上一层代理 IP是192.168.1.100 端口号是8099

http_access allow all #允许所有的用户通过代理进行http访问，在3.0版本之前还需要在这条配置之前添加一行acl all src 0.0.0.0/0.0.0.0，但是3.0版本后默认有了这条配置

never_direct allow all #所有请求转至上层代理

3、生成日志文件

# mkdir /var/squid

# touch /var/squid/cache.log

# chmod 777 /var/squid/cache.log

/usr/local # chmod -R 777 squid

4、重建缓存并启动服务

/usr/local/squid/sbin # ./squid -z

/usr/local/squid/sbin # 2017/03/07 16:07:33 kid1| Set Current Directory to /usr/local/squid/var/cache/squid
