域名跳转

域名跳转就是当你访问老域名时会自动跳转到新域名上面，因为你的老客户可能不知道你换域名了，他还会访问你的老域名，这样的话若不做跳转他就访问不到，他就会认为你的网站出毛病了，很可能失去一个老客户，所以我们在用新域名的同时，老域名也不要丢掉，做下跳转就ok了。下面是按照我自己的做的，视情况而定
把老站停掉
这里依自己的配置文件实际目录而定，我这里是按照自己的，配置文件目录/usr/local/nginx/conf/vhost 网站目录 /webdata/data/yungui.com
# cd /usr/local/nginx/conf/vhost
# mv yungui.conf yungui.conf.bak
# /etc/init.d/nginx  reload
# /usr/local/nginx/sbin/nginx -t
# vim yungui.conf.bak   修改配置文件
server
        {
                listen 192.168.0.12:80;
                server_name www.hehuan.com;
                index index.html index.htm index.php;
                root  /webdata/data/yungui.com/;       
        if (!-e $request_filename) {
          rewrite ^(.+)$ /index.php last;
          }

                location ~ .*\.(php|php5)?$
                        {
                                try_files $uri =404;
                                fastcgi_pass  unix:/tmp/php-cgi.sock;
                                fastcgi_index index.php;
                                include fcgi.conf;
                        }

                location /status {
                        stub_status on;
                        access_log   off;
                }

                location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
                        {
                                expires      30d;
                        }

                location ~ .*\.(js|css)?$
                        {
                                expires      12h;
                        }

                access_log  /home/wwwlogs/access.log  access;

数据库导出
# cd /webdata/data/yungui.com/app/etc/
# cat local.xml 这个文件中有用户名、数据库名、密码
# mysqldump -hlocalhost -umagento -p magento01 > my0709.sql
# vim my.sql
 %s/yungui.com/hehuan.com/g
 :wq
 
导入
# mysql -hlocalhost -u magento  -p  数据库名（magento01）< my0709.sql
# cd /webdata/data/yungui.com/var/
# rm -rf session/* cache/*
