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~

    Reading this brought back the satisfaction I used to get from blogs ten years ago, and a stop at contemporarylivingstore kept that nostalgic quality alive, sites that capture what was good about an earlier era of internet writing are increasingly precious and this one is doing that without feeling like a deliberate throwback at all.

    Reading this gave me the rare experience of fully agreeing with all the conclusions, and a stop at zestvendor continued that agreement pattern, content that aligns with my existing views without seeming designed to do so is just content that happens to be reasonable and this site reads as reasonable rather than ideological mostly.

    Honest assessment is that this is one of the better short reads I have had this week, and a look at saucierstudio reinforced that, the bar for short content is low because most of it sacrifices substance for brevity but this site manages both at once which is harder than it sounds for most writers attempting it.

    Worth pointing out that the post avoided the temptation to summarise everything at the end, and a look at mistmarket continued that confident closing approach, content that trusts readers to retain the substance without being reminded of it at the end is content that respects the reader and this site practices that respect.

    Ended up here on a wandering afternoon and was glad I stayed for the read, and a stop at blazeclose extended the wandering into a proper exploration of the site, the kind of place that rewards aimless clicking with something genuinely interesting rather than the shallow content that mostly populates the modern open web.

    A handful of memorable phrases from this one I will probably use later, and a look at civiccask added a couple more, content that contributes language to my own communication rather than just facts is content with a different kind of utility and this site is providing that linguistic utility consistently across what I read.

    Beyond the immediate post itself the editorial sensibility behind the site is what struck me, and a stop at balticarrow continued displaying that sensibility, content that reveals editorial choices through accumulated reading is content with structural quality and this site has clearly developed an underlying approach worth identifying through multiple sessions of reading.

    Liked the way the post handled the final paragraph, no neat bow but no abrupt cutoff either, and a stop at contemporarylivingstore continued that thoughtful ending pattern, endings are hard and most blog writers either over engineer them or skip them entirely and this site has clearly figured out a sustainable middle approach.

    Top quality material, deserves more attention than it probably gets, and a look at consciousconsumerhub reflected the same effort across the site, a hidden gem in the modern web where most attention goes to whoever shouts loudest rather than whoever actually delivers the best content for their readers without much marketing fanfare.

  10. OmarPucky

    Now appreciating that the post did not require me to agree with the writer to find it valuable, and a look at compasscabin maintained the same useful regardless of agreement quality, content that informs even when it does not convince is content with broader utility and this site reads as useful even when I disagree.

    Reply
  11. Grantidesy

    Worth recognising that the post did not pretend to be the final word on the topic, and a stop at zestvendor continued that humility, content that admits its own scope and limits is more trustworthy than content that overreaches and this site has clearly developed the editorial maturity to know what it can and cannot claim well.

    Reply
  12. Claytonmooto

    Thanks for putting in the work to make this approachable, plenty of sites cover the same ground but most do it badly, and a quick visit to mistmarket confirmed this one stands apart, simple language and useful examples without anyone trying to sell me anything along the way which I really appreciated.

    The headings made navigating the post simple even when I needed to find a specific section quickly, and a look at ariabee continued the same thoughtful structure, small details like clear headings show that someone is actually thinking about how the reader uses the page rather than just filling it for length alone.

    Reply
  14. RossWat

    Solid information that lines up with what I have been hearing from other reliable sources, and after my visit to saucierstudio I was even more certain of that, this site checks out which is something I value highly when so many places online play loose with the facts to chase a quick click.

    Reply
  15. Marshallbam

    Thanks for a post that does not try to be funny when it is not the moment for it, and a stop at blazeclose maintained the same appropriate seriousness, knowing when humour helps and when it just signals desperation for engagement is a sign of editorial maturity that many blogs have not developed yet.

    Got something practical out of this that I can apply later this week, and a stop at croccocoa added more details to think about, this is exactly the kind of content I bookmark for future reference rather than the throwaway listicles that dominate most search results these days for almost any common topic.

    Glad to have another reliable bookmark for this topic, and a look at bowbotany suggested several more pages I will be marking too, building a personal library of trustworthy resources is one of the actual rewards of careful browsing and this site is earning a place on my permanent shortlist for the topic.

    Now organising my browser bookmarks to give this site easier access, and a look at artfulhomeessentials earned the same organisational priority, the small acts of digital housekeeping I do for sites I expect to use often are themselves a measure of trust and this site has triggered the trust based housekeeping behaviour from me clearly.

    Came in expecting another generic take and got something with actual character instead, and a look at consciousconsumerhub carried that personality forward, finding a distinct voice on a saturated topic is impressive and worth pointing out when it happens because most sites end up sounding identical to their nearest competitors quickly.

    Really like that there are no exclamation marks or all caps shouting throughout the post, and a quick visit to ariabee maintained the same calm voice, restraint in punctuation signals confidence in the content and this site clearly trusts its substance to do the persuading rather than relying on typographic emphasis.

    The tone stayed consistent across the whole post which is harder than it looks for longer pieces, and a look at croccocoa continued the same voice, this kind of editorial consistency is a sign of either a single careful writer or a tightly run team and either is impressive today across the broader media environment.

  23. RandallEvaby

    Worth recognising the absence of the usual blog tropes here, and a look at artfulhomeessentials continued that fresh quality, sites that avoid the standard moves of the medium read as more original even when the content is on familiar topics and this one has clearly chosen its own path through the conventional terrain skilfully.

    A piece that demonstrated competence without performing it, and a look at bowbotany maintained the same self assured but unshowy register, the gap between competence and performance of competence is one I track and this site has clearly chosen to demonstrate rather than perform which I find much more persuasive as a reader.

    Reading this in pieces during a long afternoon and finding it consistently rewarding, and a stop at thoughtfulclickpingplatform fit naturally into the same fragmented reading pattern, sites whose posts can be read in segments without losing the thread are well suited to how I actually read these days and this one is built well.

    Pleasant surprise, the post delivered more than the headline promised, and a stop at upvendor continued that pattern of under promising and over delivering, the rarest combination on the modern web where most content does the opposite by promising the world and delivering thin recycled summaries instead each time you click on something interesting.

    Reply
  27. Raymondsab

    Really appreciate the absence of stock photos that have nothing to do with the content, and a quick visit to vaultbasket maintained the same restraint, visual filler is a tell that the writing cannot stand on its own and the lack of it here suggests the team has confidence in their content quality alone.

  28. LeoFrive

    Skipped a meeting reminder to finish the post, and a stop at blissbrick held me past another reminder, when content beats meetings the writer is doing something extraordinary because meetings have institutional support behind them and yet good writing can still occasionally win that competition for attention which I find heartening today.

    Looking at this from the perspective of someone tired of generic content the contrast is striking, and a look at alpinevendor maintained that distinctive feel, sites with strong editorial identity stand out against the bland background of algorithmic content and this one has clearly developed an identity worth recognising through careful attention.

    Reading this prompted me to dig into a related topic later, and a stop at conchbook provided some of the starting points for that follow up reading, content that triggers further exploration rather than satisfying curiosity completely is content with real generative energy and this site has plenty of that energy throughout it.

    Now thinking about how to apply some of this to a project I have been planning, and a look at upvendor added more material for the planning, content that connects to my actual creative work rather than just being interesting in the abstract is the kind that earns priority placement in my reading rotation consistently going forward.

    Reply
  33. AndrewFut

    Came away with a slightly better mental model of the topic than I started with, and a stop at thoughtfulclickpingplatform sharpened that further, content that improves the reader thinking apparatus rather than just dumping facts into it is the rare kind I genuinely value and seek out when I have time to read carefully.

  34. RomanMub

    Really like that the writer trusts the reader to follow simple logic without restating every previous point, and a stop at intentionalconsumerstore kept that respect going, treating an audience as capable adults rather than as people who need constant hand holding makes a noticeable difference in the reading experience for me.

  35. Raymondsab

    Felt like I was reading something written by someone who actually thinks about the topic rather than reciting it, and a look at vaultbasket reinforced that impression, the difference between recited content and considered content is huge and this site clearly belongs to the latter category which I appreciate as a careful reader looking for substance.

    Picked up several practical tips that I plan to try out this week, and a look at ariabrawn added a few more I will be testing alongside, content with practical hooks that connect to my actual life is the kind that earns my repeat attention rather than the merely interesting that I forget within a day.

    Now appreciating that I did not feel exhausted after reading, and a stop at blissbrick extended that energising quality, content that leaves me with more attention than it consumed is rare and the gap between draining and energising content is real over the course of a typical day spent reading widely online.

  38. Oliverhof

    Picked up something useful for a side project, and a look at clamable added another piece I will incorporate, content that connects to specific projects I am working on is content with practical utility and the practical utility of this site is showing up across multiple posts I have read in the last hour or so.

    Now thinking the topic is more interesting than I had given it credit for, and a stop at curateddesignandliving continued that elevated interest, content that revives my curiosity about subjects I had set aside is doing genuine work in the structure of my interests and this site is providing that revivifying effect today actually.

    Glad the writer did not feel the need to argue with imaginary critics in the post itself, and a stop at alpinevendor 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.

  42. Lancetoige

    Considered against the flood of similar content this one stands apart in important ways, and a stop at balticbull extended that distinctive feel, sites that find their own corner of a crowded topic and stay there are sites worth following and this one has clearly carved out its own space and committed to defending it carefully.

    Skipped the related products section because there was none, and a stop at ariabrawn also lacked any aggressive monetisation, content that is not constantly trying to convert me into a customer or subscriber is content that has confidence in its own value and that confidence shows up as a different reading experience.

    Glad I gave this a chance instead of bouncing on the headline, and after conchbook I was certain I had made the right call, snap judgements based on titles miss a lot of good content and this is a reminder to slow down and check things out before scrolling past in a hurry.

    Really grateful for content like this, it does not waste my time and it does not insult my intelligence either, and a quick look at capeasana was the same, balanced respectful writing that makes a person feel welcome rather than rushed through pages of forced engagement just to keep clicking around.

    Probably this is one of the better quiet successes on the open web at the moment, and a look at crustbeige reinforced that quiet success quality, sites that are doing well without making a noise about doing well are the sites I most respect and this one has clearly chosen the quiet success path consistently throughout.

    A piece that handled multiple complications without becoming confused, and a look at bowcask continued that organisational clarity, holding multiple threads in a single piece without losing any of them is a sign of skilled writing and this site has clearly developed the editorial discipline to manage complexity without sacrificing readability throughout.

    Reply
  49. Danfup

    Quality you can feel from the first paragraph, the writer clearly knows the topic and how to share it, and a quick look at curateddesignandliving confirmed the same depth runs throughout the rest of the site as well which is rare and worth pointing out when it happens online for any reader passing through.

    Reading this prompted a small redirection in something I was working on, and a stop at yovrisa extended that redirecting influence, content that affects my actual work rather than just my thinking has the highest practical impact and this site is providing that level of influence for me at a sustainable rate apparently.
