nginx学习整理

nginx配置文件说明

nginx.conf位于其安装目录的conf目录下

1. user是个主模块指令，指定Nginx Worker进程运行用户以及用户组，默认由nobody账号运行。

2. worker_processes:主模块指令，指定了Nginx要开启的进程数。每个Nginx进程平均耗费10M~12M内存。建议指定和CPU的数量一致即可。

3. error_log:主模块指令，用来定义全局错误日志文件。日志输出级别有debug、info、notice、warn、error、crit可供选择，其中，debug输出日志最为最详细，而crit输出日志最少。

4. pid是个主模块指令，用来指定进程pid的存储文件位置。

5. worker_rlimit_nofile用于绑定worker进程和CPU， Linux内核2.4以上可用。

6. events事件指令是设定Nginx的工作模式及连接数上限：

#user nobody;
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 {
worker_connections 1024;
}

http {
include mime.types;
default_type application/octet-stream;
sendfile on;
#tcp_nopush on;

#keepalive_timeout  0;
keepalive_timeout  65;

#gzip  on;
