今天掃描linux的服務器，發現了httpd服務存在一些安全隱患，由（yóu）於以前安裝過新版本的apache，安裝linux時自帶的httpd服務就沒必要留在係統裏麵了。於是（shì）進行了：

#rpm -e httpd

結果，出現以下錯誤（wù）

        httpd-mmn = 20020628 is needed by (installed) mod_perl-1.99_07-5
        httpd-mmn = 20020628 is needed by (installed) mod_python-3.0.1-3
        httpd-mmn = 20020628 is needed by (installed) mod_ssl-2.0.40-21
        httpd-mmn = 20020628 is needed by (installed) php-4.2.2-17
        libapr.so.0 is needed by (installed) mod_perl-1.99_07-5
        libaprutil.so.0 is needed by (installed) mod_perl-1.99_07-5
        webserver is needed by (installed) webalizer-2.01_10-11
        httpd >= 2.0.40 is needed by (installed) mod_perl-1.99_07-5
        httpd >= 2.0.40 is needed by (installed) mod_python-3.0.1-3
        httpd is needed by (installed) mod_ssl-2.0.40-21

看來，要卸載這些東（dōng）西還應該卸載它的依賴（lài）包（bāo），於是

#rpm -e mod_ssl
#rpm -e mod_python
#rpm -e mod_perl
#rpm -e webalizer

把所有的依賴包都卸載後

再次 #rpm -e httpd 成功！

在（zài）網上找了以下（xià）rpm還可以加一些參數

如#rpm -e httpd --nodeps可以不用卸載這些依賴包
