    auth = {
      username = "elastic"
      password = "TcqinZLhbJDFFgCqXF8r"
     }
  }
]

启动Cerebro

/usr/bin/cerebro 前端运行

[root@elk-node1]# /usr/bin/cerebro

使用Nginx做Cerebro反向代理

添加 http basic 认证文件

htpasswd -c /etc/nginx/passwd.db  admin

/etc/nginx/为认证密码文件的存放路径，passwd.db为认证密码文件，admin为

认证的用户名。

使用htpasswd 需要先安装Apache Httpd密码生成工具

yum install httpd-tools -y

或者

echo "admin:`openssl passwd admin123`" >> /etc/nginx/passwd.db

Nginx 反向代理配置

server {
        listen       55601;
        server_name  192.168.10.235;
        access_log      /var/log/nginx/access/cerebro_access.log main ;
        error_log       /var/log/nginx/error/cerebro_error.log ;
        location /{
            auth_basic "Protect cerebro";
            auth_basic_user_file /etc/nginx/passwd.db;
            proxy_pass http://127.0.0.1:9000;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Scheme $scheme;
            proxy_connect_timeout 15;
            proxy_send_timeout 30;
            proxy_read_timeout 30;
            proxy_redirect off;
            proxy_buffering off;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
   }
}

启动 Nginx 服务

#检查nginx配置
nginx   -t    
#启动nginx服务
systemctl  start nginx
#开机启动nginx服务
systemctl  enable nginx
#重载nginx服务
systemctl  reload nginx

cerebro 监听端口和监听地址配置

[root@elk-node1 cerebro]# /usr/bin/cerebro -Dhttp.port=9000 -Dhttp.address=127.0.0.1
[info] play.api.Play - Application started (Prod) (no global state)
[info] p.c.s.AkkaHttpServer - Listening for HTTP on /127.0.0.1:9000

systemctl 后台启动指定监听端口和监听地址
