在使用Haphost提供的128M内存的VPS建站时，debian7+wordpress+nginx+mysql跑起来相当吃力。然后使用Debian7+typecho+lighttpd+sqlite的搭配好，发现效果特别好，在此记录下搭建和优化过程。

1.debian 7 32位系统的优化

　　删除建站用不到的软件并清理缓存

apt-get -y purge apache2-* bind9-* xinetd samba-* nscd-* portmap sendmail-* sasl2-bin lynx memtester unixodbc python-* odbcinst-* sudo tcpdump ttf-*
apt-get autoremove && apt-get clean　

　　更新源列表和软件

apt-get -y update&&apt-get -y upgrade

　　重启并继续下一步

2.安装Lighttpd、PHP、SQLite组件并配置

　　安装软件

apt-get -y install lighttpd sqlite php5-cgi php5-curl php5-gd php5-idn php-pear php5-imagick php5-imap php5-mcrypt php5-mhash php5-ming php5-ps php5-pspell php5-recode php5-snmp php5-sqlite php5-tidy php5-xmlrpc php5-xsl

　　配置PHP

vim /etc/php5/cgi/php.ini

　　查找cgi.fix_pathinfo，去掉注释

　　新建www组www用户管理lighttpd运行

useradd -d /home/wwwroot -m -s /bin/bash www

　　创建网站默认目录

mkdir -p /home/wwwroot/default/public

　　修改网站目录和日志目录所有权

chown -R www:www /home/wwwroot/
chown -R www:www /var/log/lighttpd

　　配置Lighttpd

vim /etc/lighttpd/lighttpd.conf

　　改成如下内容

server.modules = (
"mod_access",
"mod_alias",
"mod_compress",
"mod_redirect",
"mod_rewrite",
"mod_fastcgi",
)
server.document-root        = "/home/wwwroot/default/public"
server.upload-dirs          = ( "/var/cache/lighttpd/uploads" )
server.errorlog             = "/var/log/lighttpd/error.log"
server.pid-file             = "/var/run/lighttpd.pid"
server.username             = "www"
server.groupname            = "www"
index-file.names            = ( "index.php", "index.html",
"index.htm", "default.htm",
" index.lighttpd.html" )
url.access-deny             = ( "~", ".inc" )
static-file.exclude-extensions = ( ".php", ".pl", ".fcgi" )
include_shell "/usr/share/lighttpd/use-ipv6.pl"
dir-listing.encoding        = "utf-8"
server.dir-listing          = "enable"
compress.cache-dir          = "/var/cache/lighttpd/compress/"
compress.filetype           = ( "application/x-javascript", "text/css", "text/html", "text/plain" )
include_shell "/usr/share/lighttpd/create-mime.assign.pl"
include_shell "/usr/share/lighttpd/include-conf-enabled.pl"
fastcgi.server = ( ".php" => ((
"bin-path" => "/usr/bin/php5-cgi",
"socket" => "/tmp/php.socket",
"max-procs" => 1,
"bin-environment" => (
"PHP_FCGI_CHILDREN" => "4",
"PHP_FCGI_MAX_REQUESTS" => "1000"
),
)))

　　重启Lighttpd

/etc/init.d/lighttpd restart

3.添加域名并初始化typecho

　　下载typecho并解压至默认目录/home/wwwroot/default/public

　　修改网站目录的所有权（有新文件加入，所以要重新赋权）

chown -R www:www /home/wwwroot/

　　在Lighttpd配置中配置域名

$HTTP["host"] =~ "(^|\.)yourdomain.com\.com$" {
server.document-root = "/home/wwwroot/default/public"
accesslog.filename = "/var/log/lighttpd/itbulu.com/access.log"
server.error-handler-404 = "/404.html"
}

　　重启Lighttpd

/etc/init.d/lighttpd restart

　　去域名服务商配置自己的域名解析

　　访问自己的网站并设置

搞定！
