配置lighttpd mod_mem_cache 模块做静态资源服务器

安哥网络

一  　lighttpd 简介
Lighttpd 是一个德国人领导的开源Web服务器软件，其根本的目的是提供一个专门针对高性能网站，安全、快速、兼容性好并且灵活的web server环境。具有非常低的内存开销，cpu占用率低，效能好，以及丰富的模块等特点。
二 下载lighttpd,并编译安装lighttpd

1.      wget http://lighttpd-improved.googlecode.com/files/lighttpd-1.4.26.modcache.v.1.8.3-2.tar.gz
   
2. 
   
3.     #tar  xf  lighttpd-1.4.26.modcache.v.1.8.3-2.tar.gz
   
4. 
   
5.     #cd   lighttpd-1.4.26
   
6. 
   
7.     # ./configure --prefix=/usr/local/lighttpd --with-zlib --with-bzip2 --with-memcache
   
8. 
   
9.     #make && make install
   
10. 
    
11.     #cd  doc
    
12. 
    
13.     #cp   rc.lighttpd.redhat    /etc/init.d/lighttpd
    
14. 
    
15.     #cp sysconfig.lighttpd  /etc/sysconfig/lighttpd
    
16. 
    
17.     #vim /etc/sysconfig/lighttpd  
    
18. 
    
19.      修改如下
    
20. 
    
21.       LIGHTTPD_CONF_PATH=/usr/local/lighttpd/conf/lighttpd.conf
    
22. 
    
23.     #
    
24. 
    
25.     #chmod 700   /etc/init.d/lighttpd
    
26. 
    
27.     #vim 修改如下选项
    
28. 
    
29.       config: /usr/local/lighttpd/conf/lighttpd.conf
    
30. 
    
31.       config: /etc/sysconfig/lighttpd
    
32. 
    
33.       pidfile: /var/run/lighttpd.pid
    
34. 
    
35.       LIGHTTPD_CONF_PATH="/usr/local/lighttpd/conf/lighttpd.conf"
    
36. 
    
37.       lighttpd="/usr/local/lighttpd/sbin/lighttpd"
    
38. 
    
39.     #mkdir /usr/local/lighttpd/{cache,logs,conf,htdocs}
    
40. 
    
41.     #cp  lighttpd.conf /usr/local/lighttpd/conf

复制代码

三 配置详解

1.   #cd  /usr/local/lighttpd/conf
   
2. 
   
3. # cat lighttpd.conf
   
4. 
   
5. # lighttpd configuration file
   
6. 
   
7. #
   
8. 
   
9. # use it as a base for lighttpd 1.0.0 and above
   
10.
