今天掃描linux的服務(wù)器，發(fā)現(xiàn)了httpd服務(wù)存在一些安全隱患，由于以前安裝過新版本的apache，安裝linux時自帶的httpd服務(wù)就沒必要留在系統(tǒng)里面了。于是進行了：

#rpm -e httpd

結(jié)果，出現(xiàn)以下錯誤

        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，要卸載這些東西還應(yīng)該卸載它的依賴包，于是

#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后

再次 #rpm -e httpd 成功！

在網(wǎng)上找了以下rpm還可以加一些參數(shù)

如#rpm -e httpd --nodeps可以不用卸載這些依賴包
