在rhel 7.3中安裝oracle 11g時發現未安裝後者需要要的glibc-devel（32位），但已安裝了64位的，rhel 7.3的光盤映像文件中取得
glibc-devel-2.17-157.el7.i686.rpm文件進行安裝，由於沒有經驗，走了一些彎路，但也學到了一些知識。
（一）安裝，失敗，如下：
[root@localhost Desktop]# rpm -ivh glibc-devel-2.17-157.el7.i686.rpm
warning: glibc-devel-2.17-157.el7.i686.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY
error: Failed dependencies:

librt.so.1 is needed by glibc-devel-2.17-157.el7.i686
libthread_db.so.1 is needed by glibc-devel-2.17-157.el7.i686
libutil.so.1 is needed by glibc-devel-2.17-157.el7.i686
（二）32位glibc-devel應基於32位glibc,應該先安裝32位glibc,但安裝失敗，如下：
[root@localhost Desktop]# rpm -ivh glibc-2.17-157.el7.i686.rpm
warning: glibc-2.17-157.el7.i686.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY
error: Failed dependencies:
libfreebl3.so is needed by glibc-2.17-157.el7.i686
libfreebl3.so(NSSRAWHASH_3.12.3) is needed by glibc-2.17-157.el7.i686
（三）上網查，得知，應與 nss-softokn-freebl一起安裝，經查，本機已裝64位的，未裝32位，從映像文件中取得 nss-softokn-freebl-3.16.2.3-14.4.el7.i686.rpm文件，安裝，失敗。
[root@localhost Desktop]# rpm -ivh nss-softokn-freebl-3.16.2.3-14.4.el7.i686.rpm
warning: nss-softokn-freebl-3.16.2.3-14.4.el7.i686.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY
error: Failed dependencies:
libc.so.6 is needed by nss-softokn-freebl-3.16.2.3-14.4.el7.i686
libc.so.6(GLIBC_2.0) is needed by nss-softokn-freebl-3.16.2.3-14.4.el7.i686

libc.so.6(GLIBC_2.3.4) is needed by nss-softokn-freebl-3.16.2.3-14.4.el7.i686
libc.so.6(GLIBC_2.4) is needed by nss-softokn-freebl-3.16.2.3-14.4.el7.i686

libdl.so.2(GLIBC_2.0) is needed by nss-softokn-freebl-3.16.2.3-14.4.el7.i686
libdl.so.2(GLIBC_2.1) is needed by nss-softokn-freebl-3.16.2.3-14.4.el7.i686
（四） glibc和nss-softokn-freebl一起安裝，成功。
rpm -ivh glibc-2.17-157.el7.i686.rpm nss-softokn-freebl-3.16.2.3-14.4.el7.i686.rpm
warning: glibc-2.17-157.el7.i686.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY

2:glibc-2.17-157.el7 ################################# [100%]
注：同時安裝時兩個包的順序隨意。
注：同樣，安裝後如需卸載也必須一起卸載，單獨卸載則不能成功，命令如下。
# rpm -e glibc-2.17-157.el7.i686 nss-softokn-freebl-3.16.2.3-14.4.el7.i686
（五）最後安裝glibc-devel，成功。
[root@localhost Desktop]# rpm -ivh glibc-devel-2.17-157.el7.i686.rpm
warning: glibc-devel-2.17-157.el7.i686.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY
