它的功能也不算差啦！最重要的，它至少要支援php，要不就沒戲唱了！
不過很不幸的，CentOS並未將它包含在內，如果要安裝的話，就得下載原始碼自行編譯。「編譯」!?再說吧！先找rpm套件吧！
還好有個套件叫RPMforge，它將一些好用的東東整理成軟件庫，方便使用者可以直接用yum安裝一些套件。先到http://packages.sw.be/網上去找找。
一、先安裝維護者的金鑰
二、下載
三、驗證檔案
四、安裝
[root@centos5 ~]# wget http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.i386.rpm
[root@centos5 ~]# rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt
[root@centos5 ~]# rpm -K rpmforge-release-0.5.2-2.el5.rf.i386.rpm
rpmforge-release-0.5.2-2.el5.rf.i386.rpm: (sha1) dsa sha1 md5 gpg OK
[root@centos5 ~]# rpm -ivh rpmforge-release-0.5.2-2.el5.rf.i386.rpm

接著就來安裝lighttpd
[root@centos5 ~]# yum install lighttpd

修改一下權限
[root@centos5 ~]# mkdir -p /var/run/lighttpd/
[root@centos5 ~]# chown lighttpd /var/run/lighttpd
檢查tcp 80是不是被佔住
[root@centos5 ~]# netstat -an |grep :80
檢查組態檔語法是否正確
[root@centos5 ~]# lighttpd -t -f /etc/lighttpd/lighttpd.conf
Syntax OK
就給它啟動吧！沒想到發生下面的錯誤，起不來…
[root@centos5 lighttpd]# service lighttpd start
Starting lighttpd: 2011-07-06 16:03:23: (server.c.722) couldn't set 'max filedescriptors' Operation not permitted
[FAILED]
原因是和SELinue的policy衝突了，要修改一下。
[root@centos5 lighttpd]# /usr/sbin/semodule -DB
[root@centos5 lighttpd]# service auditd restart
[root@centos5 lighttpd]# grep lighttpd /var/log/audit/audit.log | audit2allow -M lighttpdmaxfds2
******************** IMPORTANT ***********************
To make this policy package active, execute:
semodule -i lighttpdmaxfds2.pp
[root@centos5 lighttpd]# semodule -i lighttpdmaxfds2.pp
[root@centos5 lighttpd]# service lighttpd restart
Stopping lighttpd: [FAILED]
Starting lighttpd: [ OK ]
不過CentOS預設有啟動iptables，所以tcp 80是不被放行的，另外預設的根目錄裏/srv/www裏沒檔案，所以得自行建個檔案，要不然從瀏覽器中一直會顯示404的錯誤喔！
