nginx負載均衡配置-windows
雖然說windows上的nginx在官方文檔中提到"僅作為測試"之用，但對于小規(guī)模并發(fā)場景還是比apache有不小的優(yōu)勢。所以，本文也將其作為windows服務器上負載均衡的主要工具進行說明。
配置實例
#user nobody;
#指定nginx進程數，通常與CPU數相一致。特別是在windows平臺中，這一數值一般只能設置為1.
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
# windows平臺基本只能設置為1024
worker_connections 1024;
}
