## Some Variable definition which will make chrooting easier.
##
## if you add a variable here. Add the corresponding variable in the
## chroot example aswell.
##
## 我最终移植到板子上的时候把install文件夹名字改成了lighttpd，文件夹放
## 在根目录"/"下,所以下面几个目录对应如下
var.log_root    = "/lighttpd/log"
var.server_root = "/lighttpd"
var.state_dir   = "/lighttpd"
var.home_dir    = "/lighttpd"
var.conf_dir    = "/lighttpd/config"

## 
## run the server chrooted.
## 
## This requires root permissions during startup.
##
## If you run Chrooted set the the variables to directories relative to
## the chroot dir.
##
## example chroot configuration:
## 
#var.log_root    = "/logs"
#var.server_root = "/"
#var.state_dir   = "/run"
#var.home_dir    = "/lib/lighttpd"
#var.vhosts_dir  = "/vhosts"
#var.conf_dir    = "/etc"
#
#server.chroot   = "/srv/www"

##
## Some additional variables to make the configuration easier
##

##
## Base directory for all virtual hosts
##
## used in:
## conf.d/evhost.conf
## conf.d/simple_vhost.conf
## vhosts.d/vhosts.template
##
## 这里server_root和"/vhost"，两个字符串加起来正好"/lighttpd/vhost",正
## 好对应刚刚新建的vhosts
var.vhosts_dir  = server_root + "/vhosts"

##
## Cache for mod_compress
##
## used in:
## conf.d/compress.conf
##
## 同vhosts
var.cache_dir   = server_root + "/cache"

##
## Base directory for sockets.
##
## used in:
## conf.d/fastcgi.conf
## conf.d/scgi.conf
##
## 同vhosts
var.socket_dir  = home_dir + "/sockets"

##  Basic Configuration
## ---------------------
##
## 服务器端口80，没啥说的
server.port = 80

##
## Use IPv6?
##
## 禁用ipv6，我们编译的时候禁用ipv6了。可以翻回去看编译配置
server.use-ipv6 = "disable"

##
## bind to a specific IP
##
#server.bind = "localhost"

##
## Run as a different username/groupname.
## This requires root permissions during startup. 
##
## 看翻译这里是用一个不同的身份启动运行服务器，我这里注释了，直接root干就好
## server.username  = "lighttpd"
## server.groupname = "lighttpd"

##
## Enable lighttpd to serve requests on sockets received from systemd
## https://www.freedesktop.org/software/systemd/man/systemd.socket.html
##
#server.systemd-socket-activation = "enable"

## 
## enable core files.
##
#server.core-files = "disable"

##
## Document root
##
## 同vhosts，这个文件夹存放html文件
server.document-root = server_root + "/webpages"

##
## The value for the "Server:" response field.
##
## It would be nice to keep it at "lighttpd".
##
#server.tag = "lighttpd"

##
## store a pid file
##
## 同vhosts
server.pid-file = state_dir + "/lighttpd.pid"

##

##
##  Logging Options
## ------------------
##
## all logging options can be overwritten per vhost.
##
## Path to the error log file
##
server.errorlog             = log_root + "/error.log"

##
## If you want to log to syslog you have to unset the 
## server.errorlog setting and uncomment the next line.
##
#server.errorlog-use-syslog = "enable"

##
## Access log config
## 
## 访问日志调试时候先开着，最终部署时候看需求开关(据说生成的日志文件比
## 较大，如果部署开启这个考虑要定时删除)
include "conf.d/access_log.conf"

##
## The debug options are moved into their own file.
## see conf.d/debug.conf for various options for request debugging.
##

##  Tuning/Performance
## --------------------
##
## corresponding documentation:
## https://redmine.lighttpd.net/projects/lighttpd/wiki/Docs_Performance
##
## set the event-handler (read the performance section in the manual)
##
## possible options on linux are:
##
## select
## poll
## linux-sysepoll
##
## linux-sysepoll is recommended on kernel 2.6.
##
server.event-handler = "linux-sysepoll"

##
## The basic network interface for all platforms at the syscalls read()
## and write(). Every modern OS provides its own syscall to help network
## servers transfer files as fast as possible 
##
## sendfile       - is recommended for small files.
## writev         - is recommended for sending many large files
##
server.network-backend = "sendfile"

##
## As lighttpd is a single-threaded server, its main resource limit is
## the number of file descriptors, which is set to 1024 by default (on
## most systems).
##
## If you are running a high-traffic site you might want to increase this
## limit by setting server.max-fds.
##
## Changing this setting requires root permissions on startup. see
## server.username/server.groupname.
##
## By default lighttpd would not change the operation system default.
## But setting it to 2048 is a better default for busy servers.
##
## 这里只是一个简单的服务器，用不着2048，我这里用256，
server.max-fds = 256

##
## listen-backlog is the size of the listen() backlog queue requested when
## the lighttpd server ask the kernel to listen() on the provided network
## address.  Clients attempting to connect() to the server enter the listen()
## backlog queue and wait for the lighttpd server to accept() the connection.
##
## The out-of-box default on many operating systems is 128 and is identified
## as SOMAXCONN.  This can be tuned on many operating systems.  (On Linux,
## cat /proc/sys/net/core/somaxconn)  Requesting a size larger than operating
## system limit will be silently reduced to the limit by the operating system.
##
## When there are too many connection attempts waiting for the server to
## accept() new connections, the listen backlog queue fills and the kernel
## rejects additional connection attempts.  This can be useful as an
## indication to an upstream load balancer that the server is busy, and
## possibly overloaded.  In that case, configure a smaller limit for
## server.listen-backlog.  On the other hand, configure a larger limit to be
## able to handle bursts of new connections, but only do so up to an amount
## that the server can keep up with responding in a reasonable amount of
## time.  Otherwise, clients may abandon the connection attempts and the
## server will waste resources servicing abandoned connections.
##
## It is best to leave this setting at its default unless you have modelled
## your traffic and tested that changing this benefits your traffic patterns.
##
## Default: 1024
##
#server.listen-backlog = 128

##
## Stat() call caching.
##
## lighttpd can utilize FAM/Gamin to cache stat call.
##
## possible values are:
## disable, simple or fam.
##
server.stat-cache-engine = "simple"

##
## Fine tuning for the request handling
##
## max-connections == max-fds/2 (maybe /3)
## means the other file handles are used for fastcgi/files
##
## 这个和max-fds 这个数值有关系，注意上面官方英语注释
server.max-connections = 128

##
## How many seconds to keep a keep-alive connection open,
## until we consider it idle. 
##
## Default: 5
##
#server.max-keep-alive-idle = 5

##
## How many keep-alive requests until closing the connection.
##
## Default: 16
##
#server.max-keep-alive-requests = 16

##
## Maximum size of a request in kilobytes.
## By default it is unlimited (0).
##
## Uploads to your server cant be larger than this value.
##
#server.max-request-size = 0

##
## Time to read from a socket before we consider it idle.
##
## Default: 60
##
#server.max-read-idle = 60

##
## Time to write to a socket before we consider it idle.
##
## Default: 360
##
#server.max-write-idle = 360

##
##  Traffic Shaping 
## -----------------
##
## see /usr/share/doc/lighttpd/traffic-shaping.txt
##
## Values are in kilobyte per second.
##
## Keep in mind that a limit below 32kB/s might actually limit the
## traffic to 32kB/s. This is caused by the size of the TCP send
## buffer. 
##
## per server:
##
#server.kbytes-per-second = 128

##
## per connection:
##
#connection.kbytes-per-second = 32

##  SSL Support
## ------------- 
##
## To enable SSL for the whole server you have to provide a valid
## certificate and have to enable the SSL engine.::
##
##   ssl.engine = "enable"
##   ssl.pemfile = "/path/to/server.pem"
##
##   $SERVER["socket"] == "10.0.0.1:443" {
##     ssl.engine                  = "enable"
##     ssl.pemfile                 = "/etc/ssl/private/www.example.com.pem"
##
##     # Check your cipher list with: openssl ciphers -v '...'
##     # (use single quotes as your shell won't like ! in double quotes)
##     #ssl.cipher-list             = "HIGH"   # default
##
##     # (recommended to accept only TLSv1.2 and TLSv1.3)
##     #ssl.openssl.ssl-conf-cmd = ("Protocol" => "-ALL, TLSv1.2, TLSv1.3")
##
##     server.name                 = "www.example.com"
##
##     server.document-root        = "/srv/www/vhosts/example.com/www/"
##   }
##

## If you have a .crt and a .key file, specify both ssl.pemfile and ssl.privkey,
## or cat them together into a single PEM file:
## $ cat /etc/ssl/private/lighttpd.key /etc/ssl/certs/lighttpd.crt \
##   > /etc/ssl/private/lighttpd.pem
##
#ssl.pemfile = "/etc/ssl/private/lighttpd.pem"
#
# or
#
#ssl.privkey = "/etc/ssl/private/privkey.pem"
#ssl.pemfile = "/etc/ssl/private/cert.pem"

##
## optionally pass the CA certificate here.
##
##
#ssl.ca-file = ""

##
## and the CRL revocation list here.
##
##
#ssl.ca-crl-file = ""
