将安装包通过SFTP上传至服务器中指定目录，这里放在/opt目录下
```
cd /opt
ls -l
```
创建安装目录
```
mkdir -p /usr/local/nginx/
```

解压至安装目录

tar -zxvf nginx-1.22.1.tar.gz -C /usr/local/nginx/

进入目录
```
cd /usr/local/nginx/nginx-1.22.1
```
执行编译安装命令
```
./configure
make
make install
```
进入Nginx目录
```
cd /usr/local/nginx/
```
配置nginx开机启动
```
vi /lib/systemd/system/nginx.service
```

写入以下内容

[Unit]
Description=nginx 
After=network.target 
[Service]
Type=forking
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx reload
ExecStop=/usr/local/nginx/sbin/nginx quit
PrivateTmp=true 
[Install] 
WantedBy=multi-user.target

添加到开机启动任务

systemctl daemon-reload
systemctl start nginx
systemctl enable nginx

如果出现错误可以使用如下命令查看日志
```
sudo journalctl -u nginx.service
```

3. 安装Https模块（已安装过Nginx）

进入目录
```
cd /usr/local/nginx/nginx-1.18.0
```
查看nginx原有的模块
```
/usr/local/nginx/sbin/nginx -V
```

执行编译安装命令

./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module

配置完成后，运行命令
```
make
```
将刚刚编译好的nginx覆盖掉原有的nginx（这个时候nginx要停止状态）
```
cp ./objs/nginx /usr/local/nginx/sbin/
```
启动nginx，仍可以通过命令查看是否已经加入成功
```
/usr/local/nginx/sbin/nginx -V
```

4. Configuration 防火墙

查看Nginx使用端口80
```
netstat -lnpt
```
开放端口，这里使用80端口
```
ufw allow 80/tcp
```
查看防火墙，已开放端口列表
```
ufw status
```
