apache的运行用户要对文件写的权限 ,权限设置目录、/usr/local/nagios/var/rw
查看apache进程,什么用户在运行
[root@standby objects]# ps -ef | grep http
root 4406 1 0 11:29 ? 00:00:00 /usr/sbin/httpdnagios 4408 4406 0 11:29 ? 00:00:00 /usr/sbin/httpdnagios 4409 4406 0 11:29 ? 00:00:00 /usr/sbin/httpdnagios 4410 4406 0 11:29 ? 00:00:00 /usr/sbin/httpdnagios 4411 4406 0 11:29 ? 00:00:00 /usr/sbin/httpdnagios 4412 4406 0 11:29 ? 00:00:00 /usr/sbin/httpdnagios 4413 4406 0 11:29 ? 00:00:00 /usr/sbin/httpdnagios 4414 4406 0 11:29 ? 00:00:00 /usr/sbin/httpd然后 更改权限

被监控机上安装 nagios-plugins 插件时报错
check_http.c: In function ‘process_arguments’:
check_http.c:312: 错误:‘ssl_version’ 未声明 (在此函数内第一次使用)
check_http.c:312: 错误:(即使在一个函数内多次出现,每个未声明的标识符在其
check_http.c:312: 错误:所在的函数内只报告一次。)
make[2]: *** [check_http.o] 错误 1

make[1]: *** [all-recursive] 错误 1
make[1]: Leaving directory `/root/rpm/nagios-plugins-1.4.16'

yum install openssl openssl-devel
