nagios安装配置(七）：Web界面手动发送邮件报错

今天升级了下nagios，发现在Web界面中测试手动发送报警消息时报以下错误

Error: Could not open command file '/usr/local/nagios/var/rw/nagios.cmd' for update!
The permissions on the external command file and/or directory may be incorrect. Read the FAQs on how to setup proper permissions.
An error occurred while attempting to commit your command for processing.
Return from whence you came

如果你手动修改过nagios中的rw目录的权限，可以使用下面命令恢复默认权限

cd /usr/local/src/nagios
make install-commandmode
# 它执行以下命令
/usr/bin/install -c -m 775 -o nagios -g nagcmd -d /usr/local/nagios/var/rw
chmod g+s /usr/local/nagios/var/rw

官网提供的解决方法地址：http://nagios.manubulon.com/traduction/docs25en/commandfile.html

如果按照手册的操作就是make install-commandmode是不行的，还是需要将rw目录的其他用户权限改为7

解决方法：

chmod o+rwx /usr/local/nagios/var/rw

nagios需要停止然后开启才会生效
