我正在使用一些 nagios麻烦我希望通过全新安装来解决这个问题，但是没有成功。
我检索到https://assets.nagios.com/downloads/nagioscore/releases/nagios-4.1.1.tar.gz，并且尽可能少做：
./configure --with-command-group=nagcmd
make all
make install
make install-init
make install-config
make install-commandmode
我根本没有触碰过配置文件；我只是使用示例文件。

这是在运行 ubuntu 10.10 的服务器上。我查看了 ldd 输出（没有问题）和 strace 输出（不知道），但我不知所措。有什么建议吗？

自我回答：事实证明这与更新检查有关（離開)，可以通过 nagios.cnf 中的 check_for_update 标志轻松缓解。
