lighttpd配置介绍
一,为什么要使用lighttpd?
apache不可以吗?
在支持纯静态的对象时,比如图片,文件等 ,
lighttpd速度更快,更理想
至于它和apache的比较,很多文档,大家可以google一下
二,从何处下载lighttpd?
http://www.lighttpd.net/download/
这个是它的官方站
三,如何安装?
1,编译安装
./configure --prefix=/usr/local/lighttpd
make
make install
configure完毕以后,会给出一个激活的模块和没有激活模块的清单,可以检查一下,是否自己需要的模块都已经激活,在enable的模块中一定要有“mod_rewrite”这一项,否则重新检查pcre是否安装。
2,编译后配置
cp doc/sysconfig.lighttpd /etc/sysconfig/lighttpd
mkdir /etc/lighttpd
cp doc/lighttpd.conf /etc/lighttpd/lighttpd.conf
如果你的Linux是RedHat/CentOS,那么:
cp doc/rc.lighttpd.redhat /etc/init.d/lighttpd
如果你的Linux是SuSE,那么:
cp doc/rc.lighttpd /etc/init.d/lighttpd
其他Linux发行版本可以自行参考该文件内容进行修改。
然后修改/etc/init.d/lighttpd,把
LIGHTTPD_BIN=/usr/sbin/lighttpd
改为
LIGHTTPD_BIN=/usr/local/lighttpd/sbin/lighttpd
此脚本用来控制lighttpd的启动关闭和重起:
/etc/init.d/lighttpd start
/etc/init.d/lighttpd stop
/etc/init.d/lighttpd restart
3,配置
修改/etc/lighttpd/lighttpd.conf
1)server.modules
取消需要用到模块的注释,mod_rewrite,mod_access,mod_fastcgi,mod_simple_vhost,mod_cgi, mod_compress,mod_accesslog是一般需要用到的。
我们放开 "mod_rewrite"
"mod_compress",
2)server.document-root, server.error-log,accesslog.filename需要指定相应的目录
server.document-root = "/www/phc/html/"
mkdir /usr/local/lighttpd/logs
chmod 777 /usr/local/lighttpd/logs/
touch /usr/local/lighttpd/logs/error.log
chmod 777 /usr/local/lighttpd/logs/error.log
server.errorlog = "/usr/local/lighttpd/logs/error.log"
accesslog.filename = "|/usr/sbin/cronolog /usr/local/lighttpd/logs/%Y/%m/%d/accesslog.log"
3)用什么权限来运行lighttpd
server.username = "nobody"
server.groupname = "nobody"
从安全角度来说,不建议用root权限运行web server,可以自行指定普通用户权限。
4)静态文件压缩
mkdir /usr/local/lighttpd/compress
chmod 777 /usr/local/lighttpd/compress/
compress.cache-dir = "/usr/local/lighttpd/compress/"
compress.filetype = ("text/plain", "text/html","text/javascript","text/css")
可以指定某些静态资源类型使用压缩方式传输,节省带宽,
对于大量AJAX应用来说,可以极大提高页面加载速度。
5)server.port = 81
6)#$HTTP["url"] =~ ".pdf$" {
131 # server.range-requests = "disable"
132 #}
4,优化
1 最大连接数
默认是1024
修改 server.max-fds,大流量网站推荐2048.
因为lighttpd基于线程,而apache(MPM-prefork)基于子进程,
所以apache需要设置startservers,maxclients等,这里不需要
2 stat() 缓存
stat() 这样的系统调用,开销也是相当明显的.
缓存能够节约时间和环境切换次数(context switches)
一句话,lighttpd.conf加上
server.stat-cache-engine = “fam”
lighttpd还另外提供simple(缓存1秒内的stat()),disabled选项.
相信没人会选disabled吧.
3 常连接(HTTP Keep-Alive)
一般来说,一个系统能够打开的文件个数是有限制的(文件描述符限制)
常连接占用文件描述符,对非并发的访问没有什么意义.
(文件描述符的数量和许多原因有关,比如日志文件数量,并发数目等)
这是lighttpd在keep-alive方面的默认值.
server.max-keep-alive-requests = 128
server.max-keep-alive-idle = 30
换言之,lighttpd最多可以同时承受30秒长的常连接,每个连接最多请求128个文件.
但这个默认值确实不适合非并发这种多数情况.
lighttpd.conf 中减小
server.max-keep-alive-requests
server.max-keep-alive-idle
两个值,可以减缓这种现象.
甚至可以关闭lighttpd keep-alive.
server.max-keep-alive-requests = 0
4 事件处理
对于linux kernel 2.6来说,没有别的可说
lighttpd.conf中加上这一句足矣
server.event-handler = “linux-sysepoll”
另外,
linux 2.4 使用 linux-rtsig
freebsd 使用 freebsd-kqueue
unix 使用 poll
5 网络处理
lighttpd 大量使用了 sendfile() 这样一个高效的系统调用.
减少了从应用程序到网卡间的距离.
(同时也减少了lighttpd对cpu的占用,这部分占用转嫁到内核身上了)
根据平台,可以设置不同的参数.
server.network-backend = “linux-sendfile”
(linux)
freebsd: freebsd-sendfile
unix: writev
如果有兴趣的话,也可以看看lighttpd在async io(aio)上的实现,仅限 lighttpd 1.5
(linux-aio-sendfile, posix-aio, gthread-aio)
此外,网络方面,核心的参数也需要适当进行修改,
这里就不需要详细说明了.
5,启动
6,配置日志
logrotate & cronolog
logrotate很粗暴,直接把进程砍了然后移动日志
cronolog就是比较不错的方式.
lighttpd用法:
accesslog.filename = " |/usr/sbin/cronolog /var/log/lighttpd/%Y/%m/%d/access_XXXX.log"
7,安装pcre
从何处下载?
http://www.pcre.org/
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-7.4.tar.bz2
安装过程:
./configure
make clean
make
make install
8,支持fam
gamin默认已安装了此包
yum install gamin-devel
另外配置时需添加:
./configure --prefix=/usr/local/lighttpd --with-fam
9,测试lighttpd的启动:
/usr/local/lighttpd/sbin/lighttpd -f /usr/local/lighttpd/etc/lighttpd.conf
10,防止盗链
#$HTTP["referer"] !~ "^($|http://.*.(chinafotopress.com|chinafotopress.cn))" {
# $HTTP["url"] =~ ".(jpg|jpeg|png|gif|rar|zip|mp3)$" {
# #url.redirect = (".*" => "http://www.baidu.com/")
# url.access-deny = (".jpg")
# }
#}
#$HTTP["referer"] == "" {
# $HTTP["url"] =~ ".(jpg|jpeg|png|gif|rar|zip|mp3)$" {
# #url.redirect = (".*" => "http://www.baidu.com/")
# url.access-deny = (".jpg")
# }
#}
日志处理
Sometimes, Google Analytics just isn't enough when it comes to
keeping and interpreting server stats. After finding a suitable log
file analyzer, AWStats, the next step involved separating out the log
files on a per domain basis. When the server was first set up,
everything was shuttled to one set of access and error log files. While
AWStats could technically analyze this log, the suggested set up
involves having one set per domain. This article details the process of
separating out the log files and making sure that these new files get
rotated correctly.
Create Log Directories
While it would be possible to keep all of the files in one directory and to just name them relative to the domain, for this tutorial we will assume that we will create subdirectories based on the domain name. The first step would be to create a directory for each domain.
sudo -u www-data mkdir /var/log/lighttpd/www.example1.com
sudo -u www-data mkdir /var/log/lighttpd/www.example2.com
Update lighttpd.conf
After creating the directories, it's time to update the lighttpd conf file in /etc/lighttpd. We'll want to set the log files by host name. We already had directives setting the server.document-root for these domains so we only added the bolded lines.
$HTTP["host"] =~ "(^|\.)example1.com"$" {
server.document-root = "/var/www/www.example1.com",
server.errorlog = "/var/log/lighttpd/www.example1.com/error.log",
accesslog.filename = "/var/log/lighttpd/www.example1.com/access.log",
}
$HTTP["host"] =~ "(^|\.)example2.com$" {
server.document-root = "/var/www/www.example2.com",
server.errorlog = "/var/log/lighttpd/www.example2.com/error.log",
accesslog.filename = "/var/log/lighttpd/www.example2.com/access.log",
}
After adding these directives, you will need to restart the server.
sudo /etc/init.d/lighttpd restart
Update Logrotate
Finally, we will want logrotate to rotate these new directories. Since our main goal is to integrate the logs with AWStats, it made sense to add a separate entry for each log directory. However, if you don't need call different scripts for the different domains, feel free to create one directive. We just copied the existing logrotate configuration and editted it for each of the domains. Below are examples of what this might look like.
/var/log/lighttpd/*.log {
daily
missingok
copytruncate
rotate 60
compress
notifempty
sharedscripts
postrotate
if [ -f /var/run/lighttpd.pid ]; then \
kill -HUP $(
fi;
endscript
}
/var/log/lighttpd/www.example1.com/*.log {
daily
missingok
copytruncate
rotate 60
compress
notifempty
sharedscripts
postrotate
if [ -f /var/run/lighttpd.pid ]; then \
kill -HUP $(
fi;
endscript
}
/var/log/lighttpd/www.example2.com/*.log {
daily
missingok
copytruncate
rotate 60
compress
notifempty
sharedscripts
postrotate
if [ -f /var/run/lighttpd.pid ]; then \
kill -HUP $(
fi;
endscript
}
To make just one configuration entry, it would look like this:
"/var/log/lighttpd/*.log" "/var/log/lighttpd/www.example1.com/*.log" "/var/log/lighttpd/www.example2.com/*.log" {
daily
missingok
copytruncate
rotate 60
compress
notifempty
sharedscripts
postrotate
if [ -f /var/run/lighttpd.pid ]; then \
kill -HUP $(
fi;
endscript
}
