各位大侠，不好意思，本人是一菜鸟，刚刚学linux，问的问题有点低级，还望大家不要见怪。
言归正传。
red hat linux 9.0 下，我想升级httpd。原来的是httpd-2.0.40-21。
我用X-scan扫描，提示有漏洞，我想升到2.0.54，
用 rpm -Uvh httpd-2.0.54-1.i386.rpm提示warning: httpd-2.0.54-1.i386.rpm: V3 DSA signature: NOKEY, key ID 751d7f27
error: Failed dependencies:
        apr >;= 0.9.5 is needed by httpd-2.0.54-1
        apr-util >;= 0.9.5 is needed by httpd-2.0.54-1
        libapr-0.so.0 is needed by httpd-2.0.54-1
        libaprutil-0.so.0 is needed by httpd-2.0.54-1
        libdb-4.1.so is needed by httpd-2.0.54-1
其它的都好办就是 libdb-4.1.so 不好整，
我下了db4-4.1
用rpm -Uvh db4-4.1.25-8.i386.rpm命令提示
