CentOS7 无法安装 Nagios 代理答案

【问题标题】：Unable to install Nagios agent on CentOS7CentOS7 无法安装 Nagios 代理
【发布时间】：2015-10-05 15:45:53
【问题描述】：

当我尝试安装从 (http://assets.nagios.com/downloads/nagiosxi/agents/linux-nrpe-agent.tar.gz) 下载的代理时，我收到了防火墙错误。我能找到的唯一解决方案是启用防火墙，但我不想这样做。

第二，我尝试了这个命令“cat /dev/null > 4-firewall”。但安装程序也返回错误“失败的脚本是：'./A-subcomponents'”

有解决办法吗？

【解决方案1】：

在包含fullinstall 的同一文件夹中，尝试通过执行以下命令创建一个空的installed.firewall 文件：

touch installed.firewall

然后尝试重新运行

./fullinstall

这是基于4-firewall的第12行：

# Was this step already completed?
if [ -f installed.firewall ]; then
    echo "Firewall rules already configured - skipping."
    exit 0
fi

如果该目录中存在名为installed.firewall 的文件，则应跳过防火墙配置步骤。

【解决方案2】：

您也可以使用以下命令在您的服务器上启用 firewalld。

要启用firewalld，

systemctl enable firewalld

启动firewalld

systemctl start firewalld

检查firewalld的状态

systemctl status firewalld
