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) libcrypto.so.6 => /usr/lib/libcrypto.so.6 (0x00d01000) libnsl.so.1 => /lib/libnsl.so.1 (0x0055c000) libc.so.6 => /lib/libc.so.6 (0x001f8000) libgssapi_krb5.so.2 => /lib/libgssapi_krb5.so.2 (0x00a49000) libkrb5.so.3 => /lib/libkrb5.so.3 (0x0038e000) libcom_err.so.2 => /lib/libcom_err.so.2 (0x00fd3000) libk5crypto.so.3 => /lib/libk5crypto.so.3 (0x00f2c000) libresolv.so.2 => /lib/libresolv.so.2 (0x0068c000) libdl.so.2 => /lib/libdl.so.2 (0x00c4c000) libz.so.1 => /lib/libz.so.1 (0x00110000) /lib/ld-linux.so.2 (0x0098f000) libkrb5support.so.0 => /lib/libkrb5support.so.0 (0x00cc4000) libkeyutils.so.1 => /lib/libkeyutils.so.1 (0x00ae7000) libpthread.so.0 => /lib/libpthread.so.0 (0x00aae000) libselinux.so.1 => /lib/libselinux.so.1 (0x00124000)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 whatprovideslibssl.so.6 查看缺少的库Loaded plugins: fastestmirror, refresh-packagekit, securityLoading mirror speeds from cached hostfile* base: mirror.bit.edu.cn* extras: mirror.bit.edu.cn* updates: mirror.bit.edu.cnopenssl098e-0.9.8e-17.el6.centos.2.i686 : A compatibility version of a general cryptography and TLS libraryRepo : baseMatched from:Other : libssl.so.6yum install -yopenssl098e-0.9.8e-17.el6.centos.2.i686check_nrpe 正常可以使用了。
