最近在做的是web server从apache到nginx的转换,
主要的工作就是日志格式还有rewrite以及虚拟主机的转换。
以下是我查阅到的比较有用的配置资料和一些总结:
1、apache的LogFormat选项(配置参数/内置变量):
(来自:http://httpd.apache.org/docs/2.2/mod/mod_log_config.html#formats)
The characteristics of the request itself are logged by placing "%
" directives in the format string, which are replaced in the log file by the values as follows:
%% |
The percent sign | ||||||
%a |
Remote IP-address | ||||||
%A |
Local IP-address | ||||||
%B |
Size of response in bytes, excluding HTTP headers. | ||||||
%b |
Size of response in bytes, excluding HTTP headers. In CLF format, i.e. a '- ' rather than a 0 when no bytes are sent. |
||||||
%{Foobar}C |
The contents of cookie Foobar in the request sent to the server. Only version 0 cookies are fully supported. | ||||||
%D |
The time taken to serve the request, in microseconds. | ||||||
%{FOOBAR}e |
The contents of the environment variable FOOBAR | ||||||
%f |
Filename | ||||||
%h |
Remote host | ||||||
%H |
The request protocol | ||||||
%{Foobar}i |
The contents of Foobar: header line(s) in the request sent to the server. Changes made by other modules (e.g. mod_headers ) affect this. If you're interested in what the request header was prior to when most modules would have modified it, use mod_setenvif to copy the header into an internal environment variable and log that value with the %{VARNAME}e described above. |
||||||
%k |
Number of keepalive requests handled on this connection. Interesting if KeepAlive is being used, so that, for example, a '1' means the first keepalive request after the initial one, '2' the second, etc...; otherwise this is always 0 (indicating the initial request). Available in versions 2.2.11 and later. |
||||||
%l |
Remote logname (from identd, if supplied). This will return a dash unless mod_ident is present and IdentityCheck is set On . |
||||||
%m |
The request method | ||||||
%{Foobar}n |
The contents of note Foobar from another module. | ||||||
%{Foobar}o |
The contents of Foobar: header line(s) in the reply. |
||||||
%p |
The canonical port of the server serving the request | ||||||
%{format}p |
The canonical port of the server serving the request or the server's actual port or the client's actual port. Valid formats are canonical , local , orremote . |
||||||
%P |
The process ID of the child that serviced the request. | ||||||
%{format}P |
The process ID or thread id of the child that serviced the request. Valid formats are pid , tid , and hextid . hextid requires APR 1.2.0 or higher. |
||||||
%q |
The query string (prepended with a ? if a query string exists, otherwise an empty string) |
||||||
%r |
First line of request | ||||||
%R |
The handler generating the response (if any). | ||||||
%s |
Status. For requests that got internally redirected, this is the status of the *original* request --- %>s for the last. |
||||||
%t |
Time the request was received (standard english format) | ||||||
%{format}t |
The time, in the form given by format, which should be in strftime(3) format. (potentially localized) |
||||||
%T |
The time taken to serve the request, in seconds. | ||||||
%u |
Remote user (from auth; may be bogus if return status (%s ) is 401) |
||||||
%U |
The URL path requested, not including any query string. | ||||||
%v |
The canonical ServerName of the server serving the request. |
||||||
%V |
The server name according to the UseCanonicalName setting. |
||||||
%X |
Connection status when response is completed:
(This directive was |
||||||
%I |
Bytes received, including request and headers, cannot be zero. You need to enable mod_logio to use this. |
||||||
%O |
Bytes sent, including headers, cannot be zero. You need to enable mod_logio to use this. |
2、nginx的log_format配置参数(内置变量):
(来自:http://nginx.org/en/docs/http/ngx_http_log_module.html#log_format)
The log format can contain common variables, and variables that exist only at the time of a log write:
$body_bytes_sent
%B
” parameter of the
mod_log_config
Apache module
$bytes_sent
$connection
$connection_requests (nginx 1.1.18版本及以后版本才有这个变量)
$msec
$pipe
p
” if request was pipelined, “
.
” otherwise
$request_length
$request_time
$status
$time_iso8601
$time_local
Header lines sent to a client have the prefix “sent_http_
”,
for example, $sent_http_content_range
.
The configuration always includes the predefined format “combined
”:
log_format combined '$remote_addr - $remote_user [$time_local] ' '"$request" $status $body_bytes_sent ' '"$http_referer" "$http_user_agent"';
