squid2.6-setup

开始squid的安装配置：

wget

#useradd squid
#groupadd squid

#tar zxvf squid-3.0.STABLE2.tar.gz
#cd squid-3.0.STABLE2
#./configure --prefix=/date/squid/squid --disable-carp --with-aufs-threads=32 --with-pthreads --enable-storeio='ufs,aufs,coss,null' --enable-disk-io='AIO,Blocking' --enable-removal-policies='heap,lru' --disable-wccp --enable-kill-parent-hack --disable-snmp --disable-poll --disable-select --enable-auth=basic --with-aio --disable-ident-lookup --with-filedescriptors=65536
#make
#make install

可能需要创建一些文件 这些都是配置文件中需要调用的（这个要注意文件的属主和权限）
#cd /date/squid/squid/var/logs/
#touch cache.log
#chmod 755 cache.log
#chown squid:squid cache.log
#touch page_zs_access_log
#chmod 755 page_zs_access_log
#chown squid:squid page_zs_access_log

#cd /date/squid/etc/

测试：
/date/squid/sbin/squid -z
/date/squid/sbin/squid -NCd1

start/stop
/date/squid/sbin/squid -sD
/date/squid/sbin/squid -k shutdown

可以根据这个测试命令用来验证squid.conf的语法和配置
/date/squid/sbin/squid -k parse

 

[root@web1 ~]# netstat -antup|grep 3128

可以查看下命中率及其他相关信息
