The next page will display another set of instructions as shown. Change your present working directory to /etc/nginx
下一页将显示另一组说明，如下所示。 将您当前的工作目录更改为/etc/nginx
# cd /etc/nginx
Next, verify that conf.d files are automatically added in Nginx configuration
接下来，确认conf.d文件已自动添加到Nginx配置中
grep -i include\.*conf nginx.conf
Next, create a new file called stub_status.conf
接下来，创建一个名为stub_status.conf的新文件。
# cat > conf.d/stub_status.conf
Copy and paste the following content into the file
复制以下内容并将其粘贴到文件中
server { listen 127.0.0.1:80; server_name 127.0.0.1; location /nginx_status { stub_status on; allow 127.0.0.1; deny all; }} Verify that the stub_status.conf file was added
验证是否已添加stub_status.conf文件
Sample Output
样本输出
Next, run the command below to reload Nginx for the stub_status module to become active.
接下来，运行以下命令重新加载Nginx，以使stub_status模块变为活动状态。
kill -HUP `cat /var/run/nginx.pid`
Click on the ‘Continue’ button to proceed to the Next page.
单击“继续”按钮进入下一页。
The final step will require modifying the /etc/nginx/nginx.conf file. We are specifically going to make adjustments to 3 sections

log_format
log_format
Finally, make the changes to this attribute as shown
最后，对该属性进行更改，如下所示
log_format main_ext '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for" ' '"$host" sn="$server_name" ' 'rt=$request_time ' 'ua="$upstream_addr" us="$upstream_status" ' 'ut="$upstream_response_time" ul="$upstream_response_length" ' 'cs=$upstream_cache_status' ;
Reload Nginx and click on ‘Finish’ button.
重新加载Nginx并单击“完成”按钮。
We’re good to go now! Be sure to observe as the metrics start streaming on the graphs as shown
我们现在走了！ 如图所示，请确保在指标开始流式传输时进行观察
