Apache重启和语法检查过程中的几个小错误解决

重启apache时出现如下提示，虽然不影响apache的正常运行，但看着就别扭，还是解决掉吧：
apache2: Could not reliably determine the server’s fully qualified domain name, using 127.0.0.1 for ServerName
[Fri Jun 03 08:42:38 2011] [warn] _default_ VirtualHost overlap on port 443, the first has precedence

apache语法检查时出现如下提示：
# apache2 -t
apache2: bad user name ${APACHE_RUN_USER}
1、# vi /etc/apache2/apache2.conf
127 User www-data
128 Group www-data

2、apache2: Could not reliably determine the server’s fully qualified domain name, using 127.0.0.1 for ServerName
解决方法：
# vi /etc/apache2/httpd.conf
添加
ServerName localhost

3、[Fri Jun 03 08:42:38 2011] [warn] _default_ VirtualHost overlap on port 443, the first has precedence
解决方法：
# vi /etc/apache2/ports.conf
添加
NameVirtualHost *:443

最后重启apache即可。
