yum update 后我的 apache 无法启动，出现以下错误：
# service httpd restart
Stopping httpd: [FAILED]
Starting httpd: httpd: Syntax error on line 13 of /etc/httpd/conf/httpd.conf: Cannot load modules/mod_authn_alias.so into server: /etc/httpd/modules/mod_authn_alias.so: cannot open shared object file: No such file or directory
[FAILED]
第 13 行如下：
Header: PidFile run/httpd.pid
# MR -- must be disable here because can not overrite! -- importance for proxy-to-apache
# Listen 80
....
Line 13: LoadModule authn_alias_module modules/mod_authn_alias.so
