/nagios/cgi-bin/cmd.cgi無法打開

原因分析，nginx不支持post。

解決方法，重新編譯nagios

1、vi /nagios-4.0.8/cgi/cmd.c

  找到printf("<form method='post' action='%s'>\n", COMMAND_CGI);

  post修改爲get

2、重新make，不需要make install

  複製新的cmd.cgi替換舊的的

  cp nagios-4.0.8/cgi/cmd.cgi /usr/local/nagios/sbin/cmd.cgi

3、Error: Could not open command file ‘/usr/local/nagios/var/rw/nagios.cmd’ for update!，有這個錯誤信息後，搜索下，得到答案：http://blog.sina.com.cn/s/blog_6eee530801010ade.html
修改nagios的啓動腳本/etc/init.d/nagios

start)
echo -n "Starting nagios:"
$NagiosBin -v $NagiosCfgFile > /dev/null 2>&1;
if [ $? -eq 0 ]; then
su - $NagiosUser -c "touch $NagiosVarDir/nagios.log $NagiosRetentionFile"
rm -f $NagiosCommandFile
touch $NagiosRunFile
chown $NagiosUser:$NagiosGroup $NagiosRunFile
$NagiosBin -d $NagiosCfgFile
if [ -d $NagiosLockDir ]; then touch $NagiosLockDir/$NagiosLockFile; fi
echo " done."
chmod -R 777 $NagiosVarDir/rw        ----增加這句話
exit 0
