lighttpd 1.5从06年到现在一直都没有放出一个稳定的版本出来，不知道现在的开发者是怎么计划的。1.5比1.4的功能貌似变化不多，最大的变化是改写了proxy模块，原先的fastcgi模块也被proxy所取代，从1.4.X升级的话就需要做一些修改。
1. 从svn check out 1.5的源代码 svn checkout svn://svn.lighttpd.net/lighttpd/trunk
2. 编译源码
编译过程可以参考源码目录下的INSTALL.svn
$ ./autogen.sh
$ ./configure --prefix=/usr/local/light --with-pcre=/usr/local/light
$ make
$ make install
注：编译时，如果没有glib2-devel库会报错找不到gthread-2.0，需要安装glib2-devel
checking for GTHREAD... configure: error: Package requirements (gthread-2.0 >= 2.4.0) were not met:
No package 'gthread-2.0' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables GTHREAD_CFLAGS
and GTHREAD_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
3. 修改配置文件
vi /usr/local/light/etc/lighttpd.conf
删除server.modules中 “mod_fastcgi”,
“mod_proxy”,
的配置，增加模块 “mod_proxy_core”, “mod_proxy_backend_fastcgi” ：
server.modules += ( "mod_proxy_core", "mod_proxy_backend_fastcgi" )
增加php的fastcgi配置
$HTTP["url"] =~ "\.php$" {
proxy-core.balancer = "round-robin"
proxy-core.allow-x-sendfile = "enable"
proxy-core.check-local = "enable"
proxy-core.protocol = "fastcgi"
proxy-core.backends = ( "unix:/tmp/php-fastcgi.sock" )
proxy-core.max-pool-size = 16
}
4. 启动fast-cgi进程
lighttpd 1.4中可以自动拉起fast-cgi进程，但1.5版本中改成了spawnfcgi方式，需要单独拉起。使用如下命令：
# /usr/local/light/bin/spawn-fcgi -s /tmp/php-fastcgi.sock -f /usr/local/light/bin/php-cgi -u lighttpd -g lighttpd -C 5 -P /var/run/spawn-fcgi.pid
注： 要保证/tmp/php-fastcgi.sock文件是lighttpd 可读写的
- 启动lighttpd
/usr/local/light/sbin/lighttpd -f /usr/local/light/etc/lighttpd.conf
注： proxy-core.check-local = “enable” 配置会导致下面错误，注释掉就没问题了。
2009-06-08 15:39:46 (error) (configfile-glue.c:169) found deprecated key in 'proxy-core.check-local' = 'use $PHYSICAL["existing-path"] =~ ... { ... } instead'
2009-06-08 15:39:46 (server.c:1507) Configuration contains deprecated keys. Going down.
