nginx 日常使用文档

安装

brew install nginx

命令

sudo nginx

sudo nginx -s reload

sudo niginx -s stop

lsof -i :端口

kill -9 进程ID

目录

/usr/local/etc/nginx

常用文件

nginx.conf

servers(api.fe-newd2c.sankuai.com.conf, fe-newd2c.sankuai.com.conf)

hosts修改

sudo vi /etc/hosts

127.0.0.1 api.fe-newd2c.sankuai.com fe-newd2c.sankuai.com  
// 127.0.0.1 nginx都是监听127.0.0.1的80端口，所以一般不会变

nginx 配置

fe-newd2c.sankuai.com.conf

server {
    listen 80;
    server_name fe-newd2c.sankuai.com;
    location / {

        proxy_pass http://127.0.0.1:4118;
        client_max_body_size 200m;
    }
}

api.fe-newd2c.sankuai.com.conf

server {
    listen 80;
    server_name api.fe-newd2c.sankuai.com;
    location / {
        proxy_set_header Host $http_host;

        proxy_pass http://127.0.0.1:3225;
        client_body_timeout 300s;
        client_max_body_size 200m;
    }
}

nginx反向代理简易说明图

同时nginx可以在本地代理做跨域（有时候会遇到后台说自己框架限制，不好设置跨域）

常见问题

nginx已经启动，想要关闭重新启动，却显示kill失败.

解决方法

mac OS：

查看端口：lsof -i :端口
杀死进程：kill -9 进程ID

linux ：

查看端口： netstat -an | grep 端口

查看nginx日志解决nginx问题

举例：本地数据图表项目，复杂数据无法上传通过查看nginx日志显示failed (13: Permission denied)：

发现报错误是：failed (13: Permission denied)：

然后通过sudo nginx 解决
