lighttpd配置

lighttpd缓存配置
Lighttpd 缓存再某些情况下，比squid要强大。

1,首先去下载带缓存模块的lighttpd源代码包
lighttpd-1.4.26.modcache.v.1.8.3-2.tar.gz
wget -S /files/lighttpd-1.4.26.modcache.v.1.8.3-2.tar.gz 2,安装包
tar zxvf lighttpd-1.4.26.modcache.v.1.8.3-2.tar.gz
cd lighttpd-1.4.26
./configure --prefix=/usr/local/lighttpd
make
make install
3,拷贝配置文件到指定的目录中
cp /usr/local/src/lighttpd-1.4.26/doc/lighttpd.conf /usr/local/lighttpd/lighttpd.conf
4,编辑配置文件
我的配置文件如下：
# lighttpd configuration file

server.modules = (
"mod_rewrite",
"mod_redirect",
"mod_access",
"mod_fastcgi",
"mod_cache", //这个要开启
"mod_proxy", //这个也必须开启，并且要注意顺序
"mod_cgi",
"mod_compress",//支持压缩
"mod_expire",
"mod_accesslog" )
server.document-root = "/var/www/html/" /配置文件目录
server.errorlog = "/var/log/lighttpd/error.log" //
s = ( "index.php", "index.html", "index.htm", "default.htm" )
# mimetype mapping
mimetype.assign = (

url.access-deny = ( "~", ".inc" )
$HTTP["url"] =~ "\.pdf$" {
server.range-requests = "disable"
}

######### Options that are good to be but not neccesary to be changed #######
## bind to port (default: 80)
#server.port = 81
## bind to localhost (default: all interfaces)
#server.bind = "127.0.0.1"
//上面这两项可以自己绑定自己需要的ip和端口
## error-handler for status 404
#server.error-handler-404 = "/error-handler.html"
#server.error-handler-404 = "/error-handler.php"
//定义错误的页面
## to help the rc.scripts
#server.pid-file = "/var/run/lighttpd.pid"
#### compress module
compress.allowed-encodings = ("bzip2", "gzip", "deflate")
compress.cache-dir = "/var/cache/lighttpd/compress/"
compress.filetype = ("text/plain", "text/html")
$HTTP["host"] == "" {
compress.cache-dir = "/var/www/cache//"
compress.filetype = ("text/plain", "text/html", "text/javascript", "text/css", "text/xml") }
上面的这些是支持压缩
下面是cache的一些设置
cache.bases = ("/cache1/cache", "/cache2/cache") //将缓存的内容存放在哪里
cache.support-queries = "enable"
cache.dynamic-mode = "enable"
//带？的url，默认是不缓存的，当cache.support-queries = "enable"、
cache.dynamic-mode = "disable"时，缓存模块会把"/uri?q1" 或者"/uri?q2"看成是相同的url而缓存起来。

当两者都为enable时则会把他们看成是不同的url而缓存起来。

cache.purge-host="^127\.0\.0\.1" //那些机器可以进行推送
下面是一些缓存规则
cache.refresh-pattern = (
"\.(?i)(flv)$" => "0 fetchall-for-range-request flv-streaming",
"\.(?i)(js|css|xml)$" => "240", # update js/css/xml every 4 hours
"\.(?i)(htm|html|shtml)$" => "30 update-on-refresh", #update html/htm/shtml every 30 minutes and on refresh requests
"\.(?i)(jpg|bmp|jpeg|gif|png)$" => "2880",
"\.(?i)(rar|zip|wmv|avi|mp3|ape|rm|mpeg|mpg|wma|asf|rmvb|flv)$" => "0 fetchall-for-range-request",
"." => "30 update-on-refresh"
)
下面设置对那些域名进行缓存
$HTTP["host"] == "" {
proxy.server = ( "/" =>
(
( "host" => "118.194.22.36", "port" => 80 )//host指的是能够提供服务的web 服务器的地址
)
)
}
当然你也可以设置多个
$HTTP["host"] == "" {
proxy.server = ( "/" =>
(
( "host" => "118.194.22.37", "port" => 80 )
)
)
}
5,启动lighttpd
/usr/local/lighttpd/sbin/lighttpd -f /usr/local/lighttpd/lighttpd.conf
6,检查是否起来
netstat -tunlp | grep lighttpd
tcp 0 0 x.x.x.x:80 0.0.0.0:* LISTEN 11034/lighttpd
7,第一次访问的时候是不会被缓存的，第二次访问的时候如果出现下面的信息，证明就缓存住了。

lighttpd缓存的规则的一些简单介绍
ignore-reload
当浏览器中定义有'Cache-Control: no-cache' 的时候，直接忽略此选项，而不去更新缓存中的内容
update-on-refresh
和上面的意思刚好相反，当浏览器中定义有'Cache-Control: no-cache' 的时候，更新缓存中的内容
override-expire
在检查Expires头部之前，先检查min值
ignore-cache-control-heade
忽略请求里面带的Cache-Control信息
ignore-vary
忽略请求里面带的'V ary' 信息
ignore-set-cookie
忽略请求里带的'Set-Cookie'信息
fetchall-for-range-request
如果浏览器请求中包含Accept-Ranges bytes那么就下载所有关联的页面，支持多线程下载参考文章：
