squid 透明代理配置过程 -- CentOS

[5 squid]# rpm -qa |grep squid

    squid-2.5.STABLE14-1.4E

    [root@centos45 squid]# service squid start

    在未设置squid.conf状况下出现错误"/var/spool/squid....."

    [root@centos45 squid]# vi squid.conf

    http_port 3128

    icp_prot 3130

    cache_dir ufs /var/spool/squid 100 16 256

    cache_access_log /var/log/squid/access.log

    cache_log /var/log/squid/cache.logcache_store_log /var/log/squid/store.log

    pid_filename /var/run/squid.pid

    #auth_param basic children 5

    #auth_param basic realm Squid proxy-caching web server

    #auth_param basic credentialsttl 2 hours

    http_access allow all

    cache_effective_user squid

    cache_effective_group squid

    [root@centos45 etc]# su -l squid -c "/usr/sbin/squid -D"

    [root@centos45 etc]# ll /usr/sbin/squid

    -rwxr-xr-x 1 root root 654724 May 5 08:13 /usr/sbin/squid

    [root@centos45 etc]# /usr/sbin/squid -D     这一步虽然不能启动squid，但可以侦察错误，不检测DNS，有一定副助作用
