nginx访问日志,错误日志参数说明

application shang 17653浏览 0评论

说明:
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。

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)” 1)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; 2)客户关掉了浏览器,而服务器还在给客户端发送数据; 3)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,会收到该错误
“(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,会收到该错误
“(111: Connection refused) while sending request to upstream” Nginxupstream连接成功后发送数据时,若遇到后端upstream挂掉或者不通,会收到该错误
“(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1Mclient发送的body超过了设置值
“reopening logs” 用户发送kill  -USR1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

“(98: Address already in use) 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

  1. “upstream prematurely(过早的) closed connection”不是,用户断掉连接,而是upstream被对端断掉连接
