今天装nagios监控的，用NRPE是提示缺少插件
今天使用check_nrpe的时候提示
-bash: /usr/local/nagios/libexec/check_nrpe: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory
估计是缺少链接库，使用下面命令
ldd /usr/local/nagios/libexec/check_nrpe
linux-gate.so.1 => (0x00647000)
libssl.so.6 => /usr/lib/libssl.so.6 (0x001ad000)

yum whatprovides ld-linux.so.2
提示缺少了glibc的库，于是yum install -y glibc.i686 ，提示消失，但是又提示缺少
./check_nrpe: error while loading shared libraries: libssl.so.6: cannot open shared object file: No such file or directory
使用：yum whatprovides libssl.so.6 查看缺少的库

yum install -y openssl098e-0.9.8e-17.el6.centos.2.i686
check_nrpe 正常可以使用了。
