quid cache（简称为Squid）是一个流行的自由软件（GNU通用公共许可证）的代理服务器和Web缓存服务器。Squid有广泛的用途，从作为网页服务器的前置cache服务器缓存相关请求来提高Web服务器的速度，到为一组人共享网络资源而缓存万维网，域名系统和其他网络搜索，到通过过滤流量帮助网络安全，到局域网通过代理上网。Squid主要设计用于在Unix一类系统运行,下面我们来看看squid3(高命中率)缓存服务器配置教程。 今天对我的varnish进行了下小小的压力测试,40s里的8000并发,没有失败一个,估计还可以承受更大的并发,先不说varnish了,我最近找到个命中率很高的squid的配置文件,当然是squid3.0的配置文件,有需要的可以copy回去自己改. 系统:centos 5.x 需要的软件:squid-3.0.STABLE25.tar.gz 1.下载squid wget http://www.squid-cache.org/Versions/v3/3.0/squid-3.0.STABLE25.tar.gz tar zxf squid-3.0.STABLE25.tar.gz && cd squid-3.0.STABLE25 2.编译squid,代码如下: ./configure --prefix=/usr/local/squid --enable-async-io=100 --with-pthreads --enable-storeio="aufs,diskd,ufs" --enable-removal-policies="heap,lru" --enable-icmp --enable-delay-pools --enable-useragent-log --enable-referer-log --enable-kill-parent-hack --enable-arp-acl --enable-default-err-language=Simplify_Chinese --enable-err-languages="Simplify_Chinese English" --disable-poll --disable-wccp --disable-wccpv2 --disable-ident-lookups --disable-internal-dns --enable-basic-auth-helpers="NCSA" --enable-stacktrace --with-large-files --disable-mempools --with-filedescriptors=65536 --enable-ssl --enable-x-accelerator-var make make install make install-pinger 3.配置squid,代码如下: cp /usr/local/squid/etc/squid.conf /usr/local/squid/etc/squid.conf.old >/usr/local/squid/etc/squid.conf ln -s /usr/local/squid/etc/squid.conf /etc/squid.conf squid.conf里的内容,代码如下: #accel listen port http_port 80 accel vhost vport #accel domain cache_peer xx.xx.xx.xx parent 80 0 no-query originserver no-digest name=a cache_peer_domain a www.phpfensi.com #acl acl manager proto cache_object acl localhost src 127.0.0.1/255.255.255.255 acl SSL_ports port 443 563 acl Safe_ports port 80 # http acl Safe_ports port 8080 acl LanSrc src all acl LanDst dst all acl LanDstDM dstdomain www.phpfensi.com acl CONNECT method CONNECT http_access allow manager localhost http_access deny manager http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access allow LanSrc http_access allow LanDst http_access allow LanDstDM http_access deny all #base visible_hostname www.phpfensi.com cache_mgr rocdk890@gmail.com cache_effective_user squid cache_effective_group squid error_directory /usr/local/squid/share/errors/Simplify_Chinese icon_directory /usr/local/squid/share/icons mime_table /usr/local/squid/etc/mime.conf cache_replacement_policy lru #cache_dir cache_dir aufs /var/cache1 32768 64 64 cache_dir aufs /var/cache2 32768 64 64 cache_mem 2048 MB max_open_disk_fds 0 #maximum_object_size 512 KB #maximum_object_size_in_memory 256 KB maximum_object_size 20 MB maximum_object_size_in_memory 8 MB #keepalived client_persistent_connections off server_persistent_connections on #persistent_request_timeout 60 seconds #memory_pools on #memory_pools_limit 64 MB forwarded_for on log_icp_queries off via off httpd_suppress_version_string off ie_refresh off tcp_recv_bufsize 32 KB #acl webservices rep_header Server -i ^linuxtoneWS ^Apache ^nginx #broken_vary_encoding allow webservices #hidden the squid header #reply_header_access Server deny all #reply_header_access X-Cache deny all #reply_header_access Warning deny all #reply_header_access Expires deny all #reply_header_access Cache-Control deny all #reply_header_access age deny all #reply_header_access All deny all ipcache_size 1024 ipcache_low 90 ipcache_high 95 memory_replacement_policy lru hosts_file /etc/hosts request_header_max_size 128 KB #deny cache hierarchy_stoplist cgi-bin ?
