news 2026/8/29 12:18:29

环境：被监控系统版本redhat7.9 splunk版本9.X.X splunk服务器地址10.10.10.10

前提条件：splunk服务器已经配置好了告警邮件服务器，接收9997端口数据，已新建索引testdata，终端可以访问splunk服务器的9997/tcp端口

一、被监控redhat系统安装客户端

1、将安装包上传到redhat系统/tmp目录

2、安装splunk客户端

rpm -ivh splunkforwarder-9.3.2-d8bb32809498.x86_64.rpm

安装过程中出现的下述错误对客户端基本功能使用不会造成影响

[root@XXX tmp]# rpm -ivh splunkforwarder-9.3.2-d8bb32809498.x86_64.rpm
warning: splunkforwarder-9.3.2-d8bb32809498.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID b3cd4420: NOKEY

complete

3、配置客户端日志外发

新建并编辑outputs.conf文件

vi /opt/splunkforwarder/etc/system/local/outputs.conf

内容为：

[tcpout] defaultGroup = primary_splunkservers [tcpout:primary_splunkservers] server = 10.10.10.10:9997 compressed = true

4、配置客户端日志收集

新建并编辑inputs.conf文件

vi /opt/splunkforwarder/etc/system/local/inputs.conf

内容为：

[monitor:///var/log/messages] sourcetype = linux_messages_log index = testdata disabled = 0

5、运行splunk客户端

启动客户端服务

/opt/splunkforwarder/bin/splunk start

[root@xxxx tmp]# /opt/splunkforwarder/bin/splunk start
Warning: Attempting to revert the SPLUNK_HOME ownership
Warning: Executing "chown -R splunkfwd:splunkfwd /opt/splunkforwarder"
