本节书摘来自异步社区《精通Nginx》一书中的第2章,第2.2节,作者: 【瑞士】Dimitri Aivaliotis 更多章节内容可以访问云栖社区“异步社区”公众号查看。
全局配置部分被用于配置对整个server都有效的参数和前一个章节中的例外格式。全局部分可能包含配置指令,例如,user和worker_processes,也包括“节、部分(section)”。例如,events,这里没有大括号({})包围全局部分。
在全局部分中,最重要的配置指令都在表2-1中,这些指令将会是你处理的最重要部分。

we want nginx to run as user www user www; the load is CPU-bound and we have 12 cores worker_processes 12; explicitly specifying the path to the mandatory error log error_log /var/log/nginx/error.log; also explicitly specifying the path to the pid file pid /var/run/nginx.pid; sets up a new configuration context for the 'events' module events { # we're on a Solaris-based system and have determined that nginx # will stop responding to new requests over time with the default # connection-processing mechanism, so we switch to the second-best use /dev/poll; # the product of this number and the number of worker_processes # indicate s how many simultaneous connections per IP:port pair are # accepted worker_connections 2048; }这一部分应该放置在nginx.conf文件的顶部。
