网站/WordPress从虚拟主机搬家到VPS上

拖了一个月终于着手并且完成了。其实没有什么难的。但是因为我对Linux的了解非常局限,还是花了一番功夫,同时学了很多东西,在这里记一下。没有试图写一篇“手把手教你搬WP”,只是记录一些我觉得有帮助的东西,希望做同样的事情的且同样不是那么牛逼的Linux学习者们有用:)

虽说是WordPress搬家,但是任何一个小型网站搬家都差不多这样了吧,嘿嘿。

如果用cPanel和MySQLAdmin之类的东西可能就很傻瓜,但是第一cPanel太贵了(竟然要425多刀一年,我都笑了),第二VPS都买了必须必须要抓住每一个学Linux的机会啊。

过程如下(断断续续弄了好几天…):

环境

虚拟主机和VPS都是host2ez的,最牛逼的主机提供商。系统是CentOS Linux 5.6,apache(现在改名叫httpd)已经装好了,再装

yum php mysql mysql-server

就成。

文件

这个简单,cPanel把虚拟主机上文件打包,VPS上wget下来就好。WP的独立性做的好,文件路径改变不会有什么问题。备份用的插件BackUpWordpress倒因为出问题了,不能识别路径,我直接禁用掉了,VPS嘛马上弄个备份方案还不容易,不需要用WP的插件了。在[wordpress path]/wp_config.php里把信息改一下,数据库部分的怎么改见下面。

数据库

对数据库命令不了解的同学建议先看一下mysql的教程。我不能把所有操作都写出来…这次弄这个还学了不少数据库的东西…tutorial很容易搜到,我觉得有一个比较好的命令列表点 这里,里面包括了所有常用的命令。

在虚拟主机的cPanel – mysqladmin里备份出.sql文件,传上VPS,导入文件的命令是

mysql – u user_name -p database_name < file_name.sql

很多地方写的-p后面跟密码,我用的版本-p后面不跟东西,回车以后才提示输密码,可能是新版本不提倡显式输入密码了吧。非要用的话就–password=”xxxxxx”

如果你导出文件选的是整个mysql,需要打开文件把database”information_schema”部分删掉,否则会失败,这个db貌似是mysql自己的,不能改..不懂

之后要建立一个用户并给此用户分配使用相应db的权限,虽然我们也可以直接把root用户写进wp_config.php但是稍微有点安全意识的程序员都不会想要这么做的…虽然权限没什么大不了的,但是名字叫root就是不行! 所以进数据库:

mysql -u root -p

进去以后添加用户:

mysql> create user 'username'@'localhost' identified by 'mypass';

分配权限:

mysql> grant all privileges on databasename.* to username@localhost;
mysql> flush privileges;

然后就把这个用户甩给Wordpress啦(编辑wp_config.php)

测试的时候有一些问题

上面完了就能http进vps的ip看到博客了,但是不要去点任何东西…因为数据库里“本站”的地址还是原来的域名,这样如果你原来的网站还开着那么随便点个链接就进到原来网站了,如果没开那就can’t find page啦。

而且因为没法进后台改,所以只好进mysql改了

mysql> use viaxlcom_viaxlcom;
mysql> select * from wp_options where option_value rlike "^http";
+-----------+---------+-------------+----------------------------+----------+
| option_id | blog_id | option_name | option_value               | autoload |
+-----------+---------+-------------+----------------------------+----------+
|         2 |       0 | siteurl     | http://axlarts.com/blog      | yes      |
|        39 |       0 | home        | http://axlarts.com           | yes      |
|        41 |       0 | ping_sites  | http://rpc.pingomatic.com/ | yes      | 
+-----------+---------+-------------+----------------------------+----------+
3 rows in set (0.06 sec)
update wp_options set option_value="http://12.34.56.78/blog" where option_id=2;
update wp_options set option_value="http://12.34.56.78" where option_id=39;

这样就把VPS上的网站地址改成本身的IP了。

————————————-
另外我发现一些插件会出现权限问题,比如JW player(放flv视频用的插件),没法启用插件因为提示不能写目录,我整个www目录都是755权限,设置成777以后可以开启了,然后再弄回来。这个问题解决了但是原因一直不知道,直到我因为另一个问题搜了一下才搞明白。

另一个问题是:更新插件update的时候会提示我输入ftp帐号,以前没这事啊,于是我就去装了个vsftpd(ftp的服务端),设置好能更新了,但是为什么?后来搜到这篇文章 <Auto Update WordPress Without FTP> 解决了ftp的问题并且意识到上面的问题也和这个有关系,即因为目录的owner不是httpd,所以网站脚本没有对文件操作的权限。

/var/www目录的owner要设置成httpd的运行者(可以用ps aux或者top命令查看),可能是www,apache或者nobody或者其他的。我的是apache,所以在chown apache:apache /var/www -R之后update就不用输ftp了,我立刻关了vsftpd依然ok,可见之前是绕了弯子了,没权限还用ftp操作文件…

绑域名

进godaddy面板直接改A地址就好了,没有别的要操作的。

但是因为我本来虚拟主机上就放了两个网站,所以怎么在一个VPS上绑定多个域名多个网站?之前用cPanel是傻瓜操作,没有怎么弄?这个我也弄了好半天最终解决了,马上再写一篇单独说吧

好啦好啦,到此结束,路人有问题可以在下面留言~

    Easy to recommend, the content speaks for itself without needing additional praise from me, and a stop at purplemilk only adds more reasons to send people this way, the kind of generous resource that benefits its readers without demanding anything in return is increasingly rare and worth recognising clearly today across the broader open internet.

    A small thank you note from me to the team behind this work, the post earned it, and a stop at poppymedal suggested more thanks would be in order over time, recognising the people who do good writing online is something I try to remember to do because the alternative is silence and silence rewards mediocrity unfortunately.

    Reading this on a difficult day was a small bright spot, and a stop at cartvilo extended that brightness, content that improves a hard day is content that has earned a particular kind of place in my reading habits and this site is occupying that uplifting role for me today which I appreciate clearly.

    Honestly enjoyed reading this more than I expected to when I first clicked through, and a stop at holmglobe kept that pleasant surprise going, sometimes you stumble onto a site that just clicks with how you like to read and this is one of those for me right now today which is great.

    Skipped the comments section but might come back to read it, and a stop at pianoledge hinted at a quality reader community, sites where the comments are worth reading separately from the post are increasingly rare and signal a particular kind of audience that has grown around the editorial vision over time gradually.

    Will recommend this to a couple of friends who have been asking about this exact topic, and after framegable I have even more reason to do so, the kind of site that earns word of mouth rather than chasing it through aggressive marketing or paid placements is always a treat to find online.

    My time on this site has now extended past what I had budgeted, and a stop at ebonkoala keeps extending it further, content that overstays its budget in my schedule is content that has earned the extra time and this site has been earning extra time across multiple visits to the point where my schedule needs adjustment.

    Skipped the comments to avoid spoilers and came back later to find them genuinely worth reading, and a stop at padreledge extended that surprised respect, when the discussion below a post matches the quality of the post itself you have found something special and this site appears to attract that kind of audience.

    Worth flagging that this approach to the topic is fresh without being contrarian, and a stop at stylevani extended the same fresh angle, finding original perspective on familiar subjects is rare and this site has clearly developed its own way of seeing rather than echoing the dominant takes from elsewhere consistently.

    Now sitting back and recognising that this was a small but real win in my reading day, and a stop at xinvoro extended that quiet win, the cumulative effect of small reading wins versus the cumulative effect of small reading losses is real over time and this site is contributing to the wins side of that ledger.

    A piece that handled a controversial angle without becoming heated, and a look at juncokudos continued that calm engagement, content that can address contested topics without inflaming them is doing rare diplomatic work and this site has clearly developed the editorial maturity to handle sensitive material with the appropriate temperature of writing throughout.

    Reply
  12. Philiplisse

    Without comparing too aggressively to other sources this one stands out for the right reasons, and a look at torzino continued that distinctive quality, content that distinguishes itself through substance rather than style tricks is content with lasting differentiation and this site has clearly chosen substance based differentiation as its core editorial strategy.

    Reply

    Liked how the writer used real examples instead of theoretical ones to make the points stick, and a stop at purplemilk added even more concrete examples, this is the kind of practical approach that respects readers who actually want to apply what they learn rather than just nodding along passively without doing anything useful.

    Honestly the simplicity is what makes this work, the topic is not buried under filler words or overly complex examples, and a quick look at navqiro showed the same sensible style, I left with what I came for and no headache from over reading which is a real win these days.

    If the topic interests you at all this is a place to spend time, and a look at vankiro reinforced that recommendation, the broader question of where to invest topical reading time is one this site answers convincingly through the consistent quality across multiple pieces I have sampled during the current reading session today.

    Skipped lunch to finish reading, which says something, and a stop at xenoframe kept me at my desk longer than planned, when content beats the lunch impulse the writer has done something genuinely impressive in an attention environment full of immediately satisfying alternatives competing for the same finite block of reader time.

    A relief to read something where I did not have to fact check every claim mentally, and a look at narrowlake continued that reliable feeling, sites where I can lower my guard and trust the content are rare and this one is earning that trust paragraph by paragraph through consistent careful work behind the scenes.

    Felt this in a way I cannot quite explain, the topic just hit different here, and a stop at xinvoro continued in that vein, sometimes you find a site whose perspective lines up with how you have been thinking and reading their work feels like a small relief which I appreciated more than I expected.

    Glad the writer did not feel the need to argue with imaginary critics in the post itself, and a stop at mavlizo kept the same focused approach going, defensive writing wastes the reader time and confidence on positions that did not need defending and this post has clearly avoided that common failure.

  21. LowellJag

    Took me back a step or two on an assumption I had been making, and a stop at qinzavo pushed that reconsideration further, writing that gently corrects the reader without being aggressive about it is a rare diplomatic skill and the team here clearly knows how to land critical points without turning readers off.

    Clean writing, easy to read, and never tries too hard to impress, that combination is harder to find than people think, and after my time on numenoat I am sure this site treats its readers well, no flashy tricks just useful content done right which is honestly all I want online.

    Generally my comment to other readers about new sites is to wait and see but for this one I would jump to recommend now, and a look at contemporarygoodsmarket reinforced that early recommendation, the speed at which a site earns my recommendation is itself a quality signal and this one has earned mine quickly clearly.

    Reading this gave me a small refresher on something I had partially forgotten, and a stop at curvecatch extended the refresher, content that strengthens existing knowledge rather than just adding new is content with a particular kind of consolidating value and this site is providing that consolidating function across multiple visits.

    Comfortable in tone and substantive in content, that is a hard combination to land, and a look at potterlily kept that pairing alive across more material, this is what good editorial direction looks like in practice and the team here clearly has someone keeping a steady hand on the wheel across what they decide to publish.

    Glad I gave this a chance rather than scrolling past, and a stop at cartzaro confirmed I made the right call, sometimes the best content is hidden behind unassuming headlines that do not scream for attention and learning to slow down and check those out has paid off many times now across years of reading.

    Just want to say thank you for putting this together, posts like these make searching online actually worth it sometimes, and a quick look at pianoloud kept that going, useful and easy to read without any of the tricks that ruin most blog comment sections lately on the wider open web.

    Reading this slowly because the writing rewards a slower pace, and a stop at narrowlake did the same, the pace at which I read content is something I now use as a quality signal and writing that earns a slower pace earns my attention as a reader looking for substance these days.

    Decent post that improved my afternoon a small amount, and a look at ebonkoala added a bit more to that, sometimes the small wins online add up over time and a useful site like this one is the kind of place that contributes consistently to those small wins for me lately across many different topics I follow.

    Reading this with a fresh mind in the morning brought out details I might have missed in the afternoon, and a stop at minimmoss earned the same fresh attention, content that rewards being read at full attention rather than at energy lows is content with real density and this site has that density consistently.

  32. IssacNesee

    Really appreciate that the writer did not stretch the post to hit some target word count, the points end when they are made, and a stop at xenoframe reflected the same discipline, brevity is generosity in disguise and this site has clearly figured that out far better than most blog operations have.

    Reply
  33. JohanFlunc

    The conclusions felt earned rather than tacked on at the end like an afterthought, and a look at vankiro kept that careful structure going, you can tell when a writer has thought about the shape of their post versus just letting it ramble out and hoping for the best at the end which most do.

    Worth a quiet moment of recognition for the consistency I have noticed across multiple posts, and a stop at padreorchid continued that consistent quality, sites that maintain quality across many pieces rather than peaking on one viral post are sites with real editorial discipline and this one has clearly developed that discipline carefully.

    Reading this in pieces over a coffee break and finding it consistently rewarding, and a stop at mavlizo extended that into related material I will return to later, the kind of site that fits naturally into small reading windows without requiring a long uninterrupted block is genuinely useful for how I actually browse.

    Nice to see a post that does not try to overcomplicate the basics for the sake of looking smart, and once I looked at numenoat the same direct tone was there too, which honestly makes a difference when you are short on time and want answers without long pointless intros.

    Now thinking about this site as a small example of what good independent writing looks like, and a stop at modluma continued that exemplary status, the few sites that serve as good examples are sites worth holding up in conversations about quality and this one has earned that exemplary placement through patient consistent effort over time.

    Honestly enjoyed every minute spent here, that is not something I say lightly, and a look at trendlyo confirmed I will be back, the bar for spending time online is high for me these days but this site clears it without effort which is high praise indeed from this reader who is usually rather demanding.

    Solid recommendation from me to anyone working in the area, the perspective here is grounded, and a look at cartzaro adds even more useful angles, the kind of site that becomes a reference rather than just a one time read which is a higher bar than most blogs ever reach today on the modern web.

    Picked this for my morning read because the topic seemed worth the time, and a look at contemporarygoodsmarket confirmed the choice was right, my morning reading slot is precious and giving it to this site felt like a good investment rather than a waste which is a higher endorsement than I usually offer for content.

    Honestly slowed down to read this carefully which is not my default, and a look at curvecatch kept me in that careful reading mode, the kind of writing that demands attention by being worth attention is rare in a media environment full of content engineered to be skimmed not read with any real focus today.

    Found this really helpful, the explanations are simple but they actually answer the questions a normal reader would have, and after I followed purplemilk I had a clearer sense of the topic, no extra fluff just useful points laid out in a sensible order that made the time worth it.

    Thanks for the simple approach, too many sites bury the actual point under layers of unnecessary words, but here every line earns its place, and a look at pianoloud showed the same care for the reader which is something I will remember the next time I need answers on a topic.

    Adding to the bookmarks now before I forget, that is how good this is, and a look at lushpassion confirmed the rest of the site is worth saving too, this is one of those rare finds that justifies the time spent searching the web for once which is a relief in the current environment.
