nginx访问日志,错误日志参数说明

摘要

nginx日志主要有两种:访问日志、错误日志。其中访问日志记录客户端访问nginx的每一个请求,包含用户地域来源、跳转来源、使用终端、某个URL访问量等信息,访问日志格式可以自定义;错误日志则记录客户端访问nginx出错时的日志,格式不支持自定义,通过错误日志,你可以得到系统某个服务或server的性能瓶颈等。两种日志都可以选择性关闭。

访问日志[Access.log]

'$status $upstream_status $body_bytes_sent "$http_referer"'

错误日志[Error.log]

错误信息 错误说明
upstream prematurely(过早的) closed connection 请求uri的时候出现的异常,
是由于upstream还未返回应答给用户时用户断掉连接造成的,
对系统没有影响,可以忽略。
recv() failed (104: Connection reset by peer) ⑴、服务器的并发连接数超过了其承载量,服务器会将其中一些连接Down掉;
⑵、客户关掉了浏览器,而服务器还在给客户端发送数据;
⑶、浏览器端按了Stop
(111: Connection refused) while connecting to upstream 用户在连接时,若遇到后端upstream挂掉或者不通。
(111: Connection refused) while reading response header from upstream 用户在连接成功后读取数据时,若遇到后端upstream挂掉或者不通。
(111: Connection refused) while sending request to upstream Nginx和upstream连接成功后发送数据时,若遇到后端upstream挂掉或者不通。
(110: Connection timed out) while connecting to upstream nginx连接后面的upstream时超时
(110: Connection timed out) while reading upstream nginx读取来自upstream的响应时超时
(110: Connection timed out) while reading response header
from upstream
nginx读取来自upstream的响应头时超时
(110: Connection timed out) while reading upstream nginx读取来自upstream的响应时超时
(104: Connection reset by peer) while connecting to upstream upstream发送了RST,将连接重置
upstream sent invalid header while reading response
header from upstream
upstream发送的响应头无效
upstream sent no valid HTTP/1.0 header while reading response
header from upstream
upstream发送的响应头无效
client intended to send too large body 用于设置允许接受的客户端请求内容的最大值,
默认值是1M,client发送的body超过了设置值
reopening logs 用户发送kill  -USR1命令
gracefully shutting down 用户发送kill  -WINCH命令
no servers are inside upstream upstream下未配置server
no live upstreams while connecting to upstream upstream下的server全都挂了
SSL_do_handshake() failed SSL握手失败
SSL_write() failed (SSL:) while sending to client
(13: Permission denied) while reading upstream
(98: Address already in use) while connecting to upstream
(99: Cannot assign requested address) while connecting to upstream
ngx_slab_alloc() failed: no memory in SSL session shared cache ssl_session_cache大小不够等原因造成
could not add new SSL session to the session cache while SSL handshaking ssl_session_cache大小不够等原因造成
