1. 启动服务。
```Shell
[root@iZwz97tbgo9lkabnat2lo8Z ~]# systemctl start firewalld

```
5. 查看网络服务和端口 - **netstat**。
```Shell
[root@iZwz97tbgo9lkabnat2lo8Z ~]# netstat -nap | grep nginx
```
6. 安全文件拷贝 - **scp**。
```Shell
[root@iZwz97tbgo9lkabnat2lo8Z ~]# scp root@1.2.3.4:/root/guido.jpg hellokitty@4.3.2.1:/home/hellokitty/pic.jpg
```
7. 安全文件传输 - **sftp**。
```Shell
[root@iZwz97tbgo9lkabnat2lo8Z ~]# sftp root@120.77.222.217
root@120.77.222.217's password:
