本文将介绍如何在Centos 7系统下安装该软件12.4版本。

1 安装前环境准备

1.1 将SELinux设置为permissive模式，并重新启动服务器

[root@centos ~]# sed -i ‘s/^SELINUX=.*/SELINUX=permissive/g’ /etc/selinux/config
[root@centos ~]# reboot

1.2 将从官网下载好的ManageEngine_NetFlowAnalyzer_64bit.bin安装包通过sftp工具上传至tmp目录
1.3 设置文件权限

[root@centos ~]# cd /tmp
[root@centos tmp]# ls
ManageEngine_NetFlowAnalyzer_64bit.bin yum.log
[root@centos tmp]# chmod a+x ManageEngine_NetFlowAnalyzer_64bit.bin
