列出仓库yum repolist
列出nginx版本yum list nginx
安装yum install -y nginx
查看版本nginx -v
查看配置文件nginx -V
systemctl enable nginx
查看整体目录结构和应用rpm -ql nginx
主配：
/etc/logrotate.d/nginx

coremodule核心模块：
user nginx; #nginx进程所使用的用户
worker_processes 1; #nginx运行的work进程数量（建议与cpu核心一致或者auto）
error_log /log/nginx/error.log #日志位置
pid /var/run/nginx.pid #nginx启动后生成的pid文件和 ps -aux|grep nginx的端口一致
events事件模块 #nginx服务运行后产生的pid进程号
events {
worker_connections 1024; #每个worker进程支持最大连接数
use epool; #事件启动模块，epool默认
}
http { #内核模块 公共配置定义

语法测试nginx -t
重载服务systemctl reload nginx/nginx -s reload
排错看日志 tail -n 10 /var/log/nginx/error.log
ro
动态监测日志
> /var/log/nginx/error.log
tail -f /var/log/nginx/error.log
