thingsboard前端缓存--nginx

thingsboard+nginx

thingsboard部署到阿里云服务器之后，由于登录界面要发送的文件很大，并且服务器的带宽目前有限，因此配置一个nginx，进行前端页面的一些缓存，参考了https://qianchenzhumeng.github.io/posts/Nginx%E5%8F%8D%E5%90%91%E4%BB%A3%E7%90%86thingsboard%E5%B9%B6%E7%BC%93%E5%AD%98%E9%9D%99%E6%80%81%E6%96%87%E4%BB%B6/
这篇文章，特此表明。
也观看了狂神说study NGINX B站视频进行学习
目前实现服务器域名直接访问，不用从8080端口访问，但是目前首次（浏览器无缓存）访问需要一分钟左右，后续登录几秒完成。

1.访问nginx官网进行下载
https://nginx.org/

点击右侧download查看所有历史版本，下载自己想要的版本。

移入linux服务器root目录下，
1、解压
tar -zxvf XXX(nginx压缩包)
2、cd进入解压后的压缩包，运行./configure，执行自动配置
3、执行make
4、执行make install

cd /usr/local/nginx/sbin/
./nginx 启动
./nginx -s stop 停止
./nginx -s quit 安全退出
./nginx -s reload 重新加载配置文件
ps aux|grep nginx 查看nginx进程

访问80端口若成功，则没问题，阿里云服务器80端口一般已经默认开放了，不过如果启动后还是访问失败可以检查，https是443端口

服务器防火墙检查命令：

开启

service firewalld start

重启

service firewalld restart

关闭

service firewalld stop

查看防火墙规则

firewall-cmd --list-all

查询端口是否开放

firewall-cmd --query-port=8080/tcp

开放80端口

firewall-cmd --permanent --add-port=80/tcp

移除端口

firewall-cmd --permanent --remove-port=8080/tcp
#重启防火墙(修改配置后要重启防火墙)
firewall-cmd --reload

参数解释

1、firwall-cmd：是Linux提供的操作firewall的一个工具；
2、–permanent：表示设置为持久；
3、–add-port：标识添加的端口；

在/usr/local/nginx下找到conf配置文件夹下的nginx.conf配置文件

执行
sudo /usr/local/nginx/sbin/nginx -s reload
重载配置文件，nginx支持热部署，一般不用重启
