1.安装
可从http://lighttpd.net/download/下载最新的源码(.tar.gz)或者rpm包。如果下载的是.tar.gz文件,则和GNU的其他软件一样,先./configure一下,然后 make && make install就搞定了。但是如果你想定制一些功能,就得好好看看解压后README, INSTALL以及./configure --help的输出结果了。这里仅仅说一下如何从源码安装,其他安装方式可参考 http://trac.lighttpd.net/trac/wiki/TutorialInstallation。
$ gzip -cd lighttpd-1.4.9.tar.gz tar xf -
...
$ cd lighttpd-1.4.9
$ ./configure --help
`configure' configures lighttpd 1.4.9 to adapt to many kinds of systems.
Usage: ./configure [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:
...
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[/usr/local]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc. You can specify
an installation prefix other than `/usr/local' using `--prefix',
for instance `--prefix=$HOME'.
For better control, use the options below.
Fine tuning of the installation directories:
...
Program names:
...
System types:
...
Optional Features:
--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
--enable-maintainer-mode enable make rules and dependencies not useful
(and sometimes confusing) to the casual installer
--disable-dependency-tracking speeds up one-time build
--enable-dependency-tracking do not reject slow dependency extractors
--enable-static[=PKGS]
build static libraries [default=no]
--enable-shared[=PKGS]
build shared libraries [default=yes]
--enable-fast-install[=PKGS]
optimize for fast installation [default=yes]
--disable-libtool-lock avoid locking (might break parallel builds)
--enable-lfs Turn on Large File System (default)
--disable-ipv6 disable IPv6 support
Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--with-gnu-ld assume the C compiler uses GNU ld [default=no]
--with-pic try to use only PIC/non-PIC objects [default=use
both]
--with-tags[=TAGS]
include additional configurations [automatic]
--with-mysql[=PATH]
Include MySQL support. PATH is the path to
'mysql_config'
--with-ldap enable LDAP support
--with-attr enable extended attribute support
--with-valgrind enable internal support for valgrind
--with-openssl[=DIR]
Include openssl support (default no)
--with-openssl-includes=DIR
OpenSSL includes
--with-openssl-libs=DIR OpenSSL libraries
--with-kerberos5 use Kerberos5 support with OpenSSL
--with-pcre Enable pcre support (default yes)
--with-bzip2 Enable bzip2 support for mod_compress
--with-fam fam/gamin for reducing number of stat() calls
--with-webdav-props properties in mod_webdav
--with-gdbm gdbm storage for mod_trigger_b4_dl
--with-memcache memcached storage for mod_trigger_b4_dl
--with-lua lua engine for mod_cml
Some influential environment variables:
...
如上所述,可通过--prefix指定安装路径,默认安装在/usr/local下。可以指定启用哪些特征(插件),禁用哪些特征(插件)。假定我们要把lighttpd安装到/usr/local/lighttpd-1.4.9下面。
$ ./configure --prefix=/usr/local/lighttpd-1.4.9
$ make
$ make install
$ cp doc/lighttpd.conf /usr/local/lighttpd-1.4.9/ # 拷贝配置文件
$ cd /usr/local/lighttpd-1.4.9
$ vi lighttpd.conf # 修改配置文件
配置文件很直观明了,一般只要把server.document-root、server.errorlog、accesslog.filename改成你的实际目录和文件名字就可以了。
$ sbin/lighttpd -f lighttpd.conf # 启动lighttpd服务
$ ps aux grep lighttpd
www 15403 0.0 0.9 2860 1148 ? S 00:15 0:00 sbin/lighttpd -f
这就完成了从安装到启动的整个过程,很简单吧。从最后一行的输出可以看出,lighttpd是单进程服务的,这和apache不一样(也许是它的稳定性不如apache的一个原因)。
2.整合php和fastcgi
以php-4.3.11为例,编译PHP的时候,不能指定 --with-apxs选项,编译命令行大致如下:
$ ./configure ... --enable-force-cgi-redirect --enable-fastcgi
$ make
$ sapi/cgi/php -v
PHP 4.3.11 (cgi-fcgi) (built: Jan 30 2006 00:12:34)
Copyright (c) 1997-2004 The PHP Group
Zend Engine v1.3.0, Copyright (c) 1998-2004 Zend Technologies
make完了后,会在sapi/cli目录生成命令行下的php程序,sapi/cgi下生成fastcgi下的php程序。如果执行sapi/cgi下的php显示版本号,你会发现有 cgi-fcgi的说明,这就表明你成功了。
$ mkdir /usr/local/lighttpd-1.4.9/fcgi
$ cp sapi/cgi/php /usr/local/lighttpd-1.4.9/fcgi/
$ vi /usr/local/lighttpd-1.4.9/lighttpd.conf
我们建立一个子目录fcgi用来保存所有的fast-cgi程序,然后把php拷贝到该目录下。编辑lighttpd.conf,如下所示:
...
server.modules = (
...
"mod_fastcgi",
...)
...
fastcgi.server = (".php" =>
( "127.0.0.1" =>
(
"socket" => "/tmp/fcgi_php.sock",
"bin-path" => "/usr/local/lighttpd-1.4.9/fcgi/php"
)
)
)
重新启动lighttpd就可以了。Lighttpd和fastcgi通信有两种方式:通过Unix socket通信,如以上PHP的启动;通过TCP/IP socket通信。Lighttpd支持基于fastcgi的负载均衡,不过我没尝试过。
关于fastcgi的协议规范,请参考http://www.fastcgi.com/,以下是我自己写的一个fastcgi的配置样例:
fastcgi.server = ( "/fastcgi/adsim" =>
( "127.0.0.1" =>
(
"host" => "127.0.0.1",
"port" => 4000,
"bin-path" => "/usr/local/lighttpd-1.4.9/fcgi/adsim",
"check-local" => "disable"
)
)
check-local必须设置为disable,否则因为找不到/fastcgi/adsim会导致请求失败。
3.制作lighttpd启动脚本
每次启动lighttpd时我们要指定配置文件的位置,停止lighttpd时要先找到进程号,然后用kill发送停止信号,有点太麻烦了。好在lighttpd自带了一个脚本程序能辅助完成这些操作,只要稍微改改就能用了,那就是源码目录doc/rc.lighttpd和doc/rc.lighttpd.redhat,后者专用于RedHat Linux。主要的改动之处在于:
...
if [ -z "$LIGHTTPD_CONF_PATH" ]; then
LIGHTTPD_CONF_PATH="/usr/local/lighttpd-1.4.9/lighttpd.conf"
fi
...
lighttpd="/usr/local/lighttpd-1.4.9/usr/sbin/lighttpd"
...
用这个脚本管理lighttpd是不是方便多了。
4.Lighttpd和OpenSSL
Lighttpd默认不编译ssl模块,所以必须在编译的时候明确指定 --with-openssl,然后再生成自签署的服务器证书或者从CA那里获取。生成自签署证书的方法如下:
$ openssl req -new -x509 -keyout server.pem \
-out server.pem -days 365 -nodes
Lighttpd要求证书和私匙保存在同一个文件里,如果是分开的,则需要合并:
$ cat host.key host.crt > host.pem
配置lighttpd.conf,大致样子如下:
ssl.engine = "enable"
ssl.pemfile = "server.pem"
你可以针对某个虚拟主机做这样的设置,但是由于SSL工作在TCP层,所以不能设置基于名称的虚拟主机,只能设置基于端口的。 以下是一个配置样例:
$SERVER["socket"] == "192.168.146.128:443" {
ssl.engine = "enable"
ssl.pemfile = "/usr/local/lighttpd/certs/server.pem"
server.document-root = "/home/www/yigeorg/www"
}
5.配置目录列表
修改 lighttpd.conf,大致如下所示:
server.module = {
...
"mod_dirlisting",
...}
dir-listing.activate = "enable"
6.配置CGI
修改lighttpd.conf,首先需要启动mod_cgi,然后在static-file.exclude-extensions中指定cgi文件的扩展名,最后通过cgi.assign配置指令进行关联。
对于带扩展名且需要特定解析程序执行的CGI,可以指定解析程序的路径,比如:
cgi.assign = ( ".pl" => "/usr/bin/perl",
".cgi" => "/usr/bin/perl" )
对于带扩展名切不需要特定解析程序就能执行的CGI,可指定解析程序为空,比如:
cgi.assign = (".cgi" => "")
对于不带扩展名的CGI程序,只能通过固定路径存取了,比如:
cgi.assgin = ( "/cgi-bin/mycgi" => "/usr/local/cgi/mycgi )
7.置虚拟主机
配置基于端口的虚拟主机上文有所描述,基于名称的虚拟主机也很简单。修改lighttpd.conf,启动模块mod_simple_vhost,然后指定你的虚拟主机信息,比如:
$HTTP["host"] == "yige.org" {
server.document-root = "/var/www/servers/news2.yige.org/pages/"
}
Lighttpd注重于速度,而Apache注重于稳定性和功能,怎么选择还得看具体的应用。
