标签: nagios

我正在使用 SELINUX=enforcing 在 CentOS 上设置 Nagios 核心。

我试着跑

chcon -R -t httpd_sys_content_t /usr/local/nagios/sbin/

按照手册中的建议，但我收到此错误消息：

chcon: can't apply partial context to unlabeled file `cmd.cgi'
chcon: can't apply partial context to unlabeled file `trends.cgi'
chcon: can't apply partial context to unlabeled file `histogram.cgi'
chcon: can't apply partial context to unlabeled file `avail.cgi'

chcon: can't apply partial context to unlabeled file `status.cgi'

我的交换内存显示SWAP critical 0% free在 NMS 上。

我试过：

 `$ swapon --show`

但什么也没有出现。我继续做：

$ free -m
         total        used        free      shared  buff/cache   available
Mem:      7873        2858        1151        1295        3863        3373
Swap:        0           0           0

然后：

$ swapon -a
swapon: /swapfile: insecure permissions 0644, 0600 suggested. 
swapon: /swapfile: read swap header failed

数月/数周前，我使用此命令在多个服务器上安装 Nagios::Plugins：

perl -MCPAN -e 'install Nagios::Plugin'

现在我收到此错误消息：

Reading '/root/.cpan/Metadata'
Database was generated on Mon, 27 Apr 2015 00:29:02 GMT
Warning: Cannot install Nagios::Plugin, don't know what it is.

据我所知，该模块仍在 CPAN 中：http : //search.cpan.org/dist/Nagios-Plugin/

怎么了？
