+#### 安装服务器的坑呀
+
+  第一次安装服务器，在安装过程中没有出现大众出现过的问题。<br>
+  首先是在开机时的提示进入bios模式用U盘启动；<br>
+  然后是按照网上教程开始进行安装，安装完成后重启再次进入bios使用磁盘启动；安装完成<br>
+  之后配置网络设置，使用内网 <br>
+    首先找到一台电脑，将其IP、子网掩码、网关、DNS全部配置到服务器网卡。然后自己的电脑要连接网线，将服务器和自己电脑的IP出于同一网段。<br>
+```js
+
+// 服务器ip
+   ip:202.75.0.62
+// 本机ip
+   ip:202.75.0.61
+
+// 可以访问外网
+
+apple@appledeMacBook-Air ~ % ping www.baidu.com

+```
+
+#### 后台部署上服务器
+
+```js
+
+nohup java -jar xx.jar  &
+
+ps -ef |grep java
+
+```
+  首先是将后台打包，注意`application.yml`的变化，然后将打包后的文件上传至服务器。<br>
+
+  ```js
+// 3306是mysql端口，为了防止被攻击将其改变
+url: jdbc:mysql://127.0.0.1:3306/micronaut_tz?serverTimezone=GMT%2B8 
+// 服务器mysql名称和密码
+username: root
+password: qaz123
+
+```
+
+如果服务器运行报错，记得查看mysql端口`show global variables like 'port';`和java进程是否被占用`ps -ef |grep java` ，关闭进程`kill -9 PID号`。<br>
+
+```js
+//mysql
+apple@appledeMacBook-Air ~ % mysql -u root -p
+Enter password:
