打开lighttpd.conf
vi /etc/lighttpd/lighttpd.conf
查找
#### compress module
#compress.cache-dir = "/tmp/lighttpd/cache/compress/"
#compress.filetype = ("text/plain", "text/html")
把前面的注释符号去掉. 需要压缩的文件类型添加在compress.filetype 里
#### compress module
compress.allowed-encodings = ("bzip2", "gzip", "deflate")
compress.cache-dir = "/tmp/lighttpd/cache/compress/"
compress.filetype = ("text/plain", "text/html", "text/javascript", "text/css")
重启lighttpd服务：
/etc/init.d/lighttpd restart
