## Installing the NodeSource Node.js 6.x repo...


## Inspecting system...

+ rpm -q --whatprovides redhat-release || rpm -q --whatprovides centos-release || rpm -q --whatprovides cloudlinux-release || rpm -q --whatprovides sl-release
+ uname -m

## Confirming "el6-x86_64" is supported...

+ curl -sLf -o /dev/null 'https://rpm.nodesource.com/pub_6.x/el/6/x86_64/nodesource-release-el6-1.noarch.rpm'

## Downloading release setup RPM...

+ mktemp
+ curl -sL -o '/tmp/tmp.l3Z6OzvS3W' 'https://rpm.nodesource.com/pub_6.x/el/6/x86_64/nodesource-release-el6-1.noarch.rpm'

## Installing release setup RPM...

+ rpm -i --nosignature --force '/tmp/tmp.l3Z6OzvS3W'

## Cleaning up...

+ rm -f '/tmp/tmp.l3Z6OzvS3W'

## Checking for existing installations...

+ rpm -qa 'node|npm' | grep -v nodesource

## Run `yum install -y nodejs` (as root) to install Node.js 6.x and npm.
## You may also need development tools to build native addons:
## `yum install -y gcc-c++ make`

Setting up SSL for Filebeat and Logstash

因为Wazuh server和Elastic Stack server是分布式架构,要配置在Filebeat和Logstash之间配SSL加密。

[[email protected] opt]# cp /etc/pki/tls/openssl.cnf custom_openssl.cnf

vi custom_openssl.cnf
找到[ v3_ca ]字段,然后在它下面添加一行elastic server的ip地址:

[ v3_ca ]
subjectAltName = IP: 192.168.106.43

writing new private key to '/etc/logstash/logstash.key'

配置Logstash server,这时在服务器中应该有了/etc/logstash/logstash.crt 证书和 /etc/logstash/logstash.key秘钥。

配置Filebeat

现在我们配置filebeat认证logstash服务器认证。
使用scp命令必须两台服务器都安装openssh-clients,yum -y install openssh-clients要在两台服务器上分别执行。

It is recommended to set up an Nginx proxy for Kibana in order to use SSL encryption and to enable authentication. Instructions to set the proxy up can be found at Setting up SSL and authentication for Kibana.https://documentation.wazuh.com/current/installation-guide/optional-configurations/kibana_ssl.html#kibana-ssl

Welcome to the Wazuh App for Kibana 5
The Wazuh App brings together a new and useful web interface for managing and monitoring your Wazuh infrastructure. You can check agent status, alert evolution, most recent events, popular alerts, top alert groups, etc. You can also display configuration and logs of the manager.

In addition, make use of any or all of these extensions:

Linux Audit system integration.
PCI DSS Compliance.
OpenSCAP security compliance and vulnerability assessments.
The app joins Wazuh features like: Log management and analysis, file integrity monitoring, intrusion and anomaly detection and policy and compliance monitoring.

Help us to improve this app. We would appreciate your feedback. Collaborate with us on the Mailing Lists and/or the Wazuh App Github repository


Please enter your Wazuh RESTful API credentials at the form below to begin.

请看上面的介绍,Wazuh主要的功能特性和扩展。新版本在上方的导航将api、扩展、关于分3个页面。

  • 添加api之前准备工作

在填用户名、密码、url、端口之前,要先到Wazuh server主机上,使用命令生成非默认的认证来保护Wazuh API。

[[email protected] ~]# service wazuh-agent start

[ OK ]

但是你会看到wazuh面板agents管理上,显示的连接过来的机器ip写的是any。因为
/var/ossec/bin/ossec-authd默认启动后,将注册any为连接ip,在服务端kill掉ossec-authd进程,然后
/var/ossec/bin/ossec-authd -i启动。在server端通过
/var/ossec/bin/manage_agents,删除已经注册的agent;在agent端删除
/var/ossec/etc/client.keys里的内容记录,重新
/var/ossec/bin/agent-auth -m 192.168.106.42注册,重启agent。
