备份你的WordPress

没有100%的安全,所以网站数据库中的数据和程序都需要定期备份。一旦出现意外,好的备份习惯可以将损失降低到最小!下面是对WordPress的备份方法。

首先是数据库备份,数据库备份有下面几种方式

  • 如果你使用的是虚拟主机,那么服务提供商一般都会提供每日的mysql数据备份。
  • 可以使用phpMyAdmin进行备份,将数据库中的表格dump成一个文本文件,然后下载到你的本地计算机中。
  • 使用WP-DB-Backup插件对数据库进行备份,前提是你需要安装另一个插件 WP-Cron
  • 最为稳妥的方式是使用Cron脚本对数据库进行dump然后发送到你的信箱。

下面就是一个Cron脚本,来自这里,做了点小小的改进,使得信件的标题显示备份的日期(要求你的服务器是*unix主机,且安装了mutt,如果没有mutt也可以使用PHP的sendmail函数写一段PHP脚本,有兴趣的可以试试):

#Set the 4 variables
#Replace what is AFTER the = with the information from your wp-config.php file
#That's your information on the right okay ?

DBNAME=DB_NAME

DBPASS=DB_PASSWORD

DBUSER=DB_USER

#Keep the " around your address
EMAIL="you@your_email.com"

mysqldump --opt -u $DBUSER -p$DBPASS $DBNAME wp_categories wp_comments wp_linkcategories wp_links wp_options wp_post2cat wp_postmeta wp_posts wp_users > backup.sql
gzip backup.sql
DATE=`date +%Y%m%d` ; mv backup.sql.gz backup-$DATE.sql.gz
echo 'Your mySQL Backup is attached' | mutt -a backup-$DATE.sql.gz $EMAIL -s "WordPress MySQL Backup "$DATA
rm backup-$DATE.sql.gz

引用本文请注意:程序中mysqldump后面的是--opt而不是-opt,wordpress默认会把--转化成-,所以请确认你把上面的代码复制到你的blog中显示的结果是正确的。

你需要将DBNAME,DBPASS,DBUSER,EMAIL这些参数更改。另外,如果你的WordPress使用的表格前缀不是wp_的话,请修改脚本。

然后,你可以使用crontab来定时调用这个程序(比如说每天凌晨时调用),将压缩的数据库dump文件发送到你的信箱里面。

其次是WordPress的程序备份。
Windows用户可以使用SyncBack Free来进行备份,也可以使用FTP工具进行定期手动备份。

找到一个可以替代ghs.google.com的地址

用Goole Blogger的自定义域名功能需要用到 ghs.google.com 做CNAME,或者用ping ghs.google.com 得出的IP做一个A记录.但是,伟大的GFW已经把 ghs.google.com 和部分IP屏蔽在大陆之外.这样的壮举使得我们的自定义域名不能正常访问,或者让你的网页背景.图片被滤掉,精心做成的模板变得惨白不堪. 那么,我们可不可以找一个替代 ghs.google.com 的地址呢?当然能.因为Google是强大的.它有许多有用的IP地址让你去探寻. 对 ghs.google.com 分析研究后发现, ghs.google.com 这台服务器并没有提供实质性的服务,而只是选择访问者访问最快的服务器(Google全球性公司,很多地区都有服务器).我们只要找到其他服务器的IP地址,并且这个IP地址没被屏蔽,那么就成了. 寻找这样的IP地址需要用到tracert命令.即在CMD模式下输入:tracert ghs.google.com ,在已经屏蔽的当下,最后自然得不出结果,这就需要我们使用代理了.使用不同地区的代理运行tracert ghs.google.com 命令. tracert ghs.google.com 的最后一跳会有类似这样的域名: eh-in-f121.google.com 如果在不用代理的情况下,你能ping通这个域名,那么恭喜你,你找到了!现在就可以用这个域名代替 ghs.google.com 设置你的CNAME了,ping出的IP地址可以做A记录,CNAME和A记录,只做其中之一就可以. hs-in-f121.google.com 64.233.179.121 eh-in-f121.google.com 72.14.207.121 bx-in-f121.google.com 66.249.81.121 ik-in-f121.google.com 66.249.91.121 这4个在我所在地区不能使用,而可以使用 tw-in-f121.google.com 72.14.235.121 或者209.85.171.121也可用 下面是一些不断更新的:74.125.43.121 除了使用代理来寻找,也可以通过一些网站提供的功能来寻找这个地址,很方便,就是使用网站提供的Traceroute.这些网站有: h...
