添加一个域名，做301跳转

1、添加域名解析，用别名来做。
vim /usr/local/apache2/conf/extra/httpd-vhosts.conf

    ServerAdmin [e-mail]
    DocumentRoot "/data/home/www/www"
    ServerName  777zp.com
    ServerAlias
    ServerAlias
    ServerAlias
    ServerAlias
    ServerAlias
    ServerAlias 777zhaopin.cn
    ServerAlias 777zhaopin.com
    ServerAlias
    ServerAlias xn--777-yh6Fq51K.com
    ServerAlias
    ServerAlias xn--777-yh6F996JckB.com
    ServerAlias
    ServerAlias xn--777-yh6fq51K.xn--fiqs8s
    ServerAlias
    ServerAlias xn--777-yh6F996JckB.xn--fiQs8S
    ServerAlias
    ServerAlias 777rencai.com
    ServerAlias
    ServerAlias 777zp.com
    ServerAlias
    ServerAlias 777zp.cn
    ServerAlias
    ErrorLog "logs/-error_log"
    CustomLog "logs/-access_log" common

添加一条 ： ServerAlias
保存退出。
2、做301跳转，修改。htaccess文件。
vim /data/home/www/www/.htaccess
