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
