注意：如果ELK起不来报 [1]: system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk 这是centos 6系统不支持SecComp 需要修改 /etc/elasticsearch/elasticsearch.yml

在server_name下加这2行

用这个或者上面那个

access_log  logs/access_json.log  json;
```
    access_log /var/log/nginx/access.log access_json;

#mkdir /var/log/nginx

#chown nginx.nginx /var/log/nginx -R

#echo "is web" > /usr/local/nginx/html/web/index.html

用页面访问一下发现日志格式变成json

vim /etc/logstash/conf.d/nginx.conf
