通过配置收集日志文件，发送到可视化页面
API接口：
软件内部代码之间通信的接口，代码的连接，代码之间调用的接口
端口是对外提供访问的接口
filebeat：
1、可以在本机收集日志
2、也可以远程收集日志
3、轻量级的日志系统，可以在非java环境运行
logstash实际在java环境中运行，资源消耗低，启动一个logstash要小号500M左右的内存
filebeat只消耗10M左右的内存
mysql nginx httpd
开一个MySQL在里面安装nginx httpd
[root@MySQL ~]# systemctl stop firewalld
[root@MySQL ~]# setenforce 0
[root@MySQL ~]# yum -y install nginx httpd
[root@MySQL opt]# vim /etc/my.cnf #开启MySQL日志文件
general_log=ON
general_log_file=/usr/local/mysql/data/mysql_general.log
#重启
[root@MySQL opt]# systemctl restart mysqld
[root@MySQL opt]# vim /etc/nginx/nginx.confserver {listen 82;#listen [::]:80;
[root@MySQL ~]# systemctl restart nginx
[root@MySQL ~]# systemctl restart httpd
[root@MySQL filebeat]# vim filebeat.yml
