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~

    Worth saying that the quiet confidence of the writing is what landed first, and a look at yornix continued that quiet quality, confident writing without the loud display of confidence is a rare combination and this site has clearly developed both the knowledge and the editorial restraint to land that combination consistently.

    Glad I clicked through from where I did because this turned out to be worth the time spent, and after dapperaisle I had a fuller picture, the kind of content that earns its visitors through delivering value rather than chasing them through aggressive advertising or constant pop ups appearing everywhere on the screen lately.

    Worth saying that this is one of the better things I have read on the topic in months, and a stop at finkglaze reinforced that ranking, the topic is well covered by many sources but few do it with this level of care and the few that do deserve to be flagged so other readers can find them.

    Liked that the post acknowledged complications rather than pretending they did not exist, and a stop at parcelwhimsy continued that honest framing, sites that handle complexity with care rather than papering it over with simplifying claims are doing real intellectual work and this one is clearly in that category based on what I have read.

    Came in for one specific question and got answers to three I had not even thought to ask, and a look at tallycove extended that bonus value pattern, the kind of resource that anticipates reader needs rather than just answering the literal question asked is the gold standard and this site reaches it.

    Started believing the writer knew the topic deeply by about the second paragraph, and a look at chipbrick reinforced that confidence, the speed at which a writer establishes credibility through their writing is a useful quality signal and this writer establishes it quickly and quietly without resorting to credential dropping or self promotion.

    Reading this gave me the rare experience of fully agreeing with all the conclusions, and a stop at basteclay 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.

    Really appreciate the absence of stock photos that have nothing to do with the content, and a quick visit to brassmarket 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.

    Thanks for taking the time to write this, it is clear that some thought went into how each point would land, and after I went through thoughtfullybuiltmarket I had a better grip on the topic, real value without the usual marketing noise people have to put up with online when searching for answers.

    Now adjusting my mental model of how the topic fits into the broader landscape, and a look at dapperaisle extended that adjustment, content that affects my structural understanding rather than just my factual knowledge is content with deeper impact and this site is providing those structural updates at a meaningful rate consistently across topics.

    Reply
  11. Juliotip

    Nice and clean, that is the best way to describe the writing here, no clutter and no wasted words, and a quick visit to parcelwhimsy kept that going, I appreciate when a site treats its readers like people who can think for themselves without needing constant hand holding through every paragraph.

    A piece that handled the topic with appropriate weight without becoming portentous, and a look at lemoncrate continued that calibrated seriousness, content that takes itself seriously without becoming pompous is something this site has clearly figured out and the balance shows up in every piece I have read across multiple sessions now.

    Walked away in a slightly better mood than when I started reading, that says something about the writing, and a stop at yornix kept that going, content that leaves you feeling more capable rather than overwhelmed is the kind I keep coming back to again and again over the years and across many topics.

  14. MackGof

    Big thanks to whoever wrote this, you saved me a lot of time hunting for the same info on other sites, and a stop at refinedconsumerhub only added more useful detail without going off topic, that kind of focus is honestly hard to come across these days when most posts wander everywhere.

    Reply

    Honestly this kind of writing is why I still bother to read independent sites, and a look at tallycove extended that broader reflection, the few sites that justify continued attention to non algorithmic content are sites like this one and finding them periodically is enough to keep my reading habits oriented toward independent rather than aggregated content.

  16. Clintonaxone

    The whole experience of reading this was pleasant from start to finish, no pop ups and no annoying interruptions, and a look at eurohilt continued that clean experience, technical choices about page design matter for the reader and this site clearly cares about the small details that add up to comfort across multiple visits.

    Reply
  17. GregBetly

    Genuine reaction is that I will probably think about this on and off for a few days, and a look at thoughtfullybuiltmarket added fuel to that, the best content lingers in your head after you close the tab rather than evaporating immediately and this site clearly knows how to write that kind of memorable content.

    Reply
  18. Eugeneinoff

    Felt this in a way I cannot quite explain, the topic just hit different here, and a stop at chipbrick 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.

  19. Bartseevy

    I really like how the writer keeps the tone friendly without sounding fake or overly polished, and after a stop at finkglint the same calm pace was there, no rushing to make a point and no padding either, just clean honest writing that I can respect and come back to later again.

  20. LucasMub

    Appreciate that you did not pad this with fluff to hit a word count, the post says what it needs to say and stops, and a look at basteclay did the same, brevity here feels intentional not lazy which is a distinction many writers miss completely sometimes when they are working under deadlines.

    Now considering writing a longer note about the post somewhere, and a look at lemoncrate added more material for that note, content that prompts me to write rather than just consume is content with generative energy and this site is producing that generative effect for me at a higher rate than most sources.

    Ended up here on a wandering afternoon and was glad I stayed for the read, and a stop at refinedconsumerhub 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.

    Reply
  23. Clintonaxone

    However many similar pages I have read this one taught me something new, and a stop at eurohilt added more new material, content that contributes genuinely fresh information rather than recycling what is already widely available is content with real informational value and this site is providing that informational freshness at a notable rate.

  24. GregInado

    If patience for careful reading is rare these days finding sites that reward it is rarer still, and a stop at lorvana extended that rare reward, the diminishing returns on shallow content reading have made me more selective about where to spend reading time and this site is meeting the higher selectivity bar consistently.

    Reply
  25. EliasJar

    Without comparing too aggressively to other sources this one stands out for the right reasons, and a look at brassmarket 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.

  26. Davonunjut

    Now thinking the topic is more interesting than I had given it credit for, and a stop at xernita 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.

    Reading more of the archives is now on my plan for the weekend, and a stop at finkglint confirmed the archive worth the time, the rare archive worth a dedicated reading session rather than just casual sampling is the rare archive of serious work and this site has clearly produced enough of that work to warrant the deeper exploration.

  28. Cliffordvop

    Felt the post was written for someone like me without explicitly addressing me, and a look at emberwharf produced the same fit, when content lands on its target without pandering you know the writer has done careful audience thinking rather than relying on demographic targeting or interest signals to do the work of editorial decisions.

    A piece that handled multiple complications without becoming confused, and a look at lorvana 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.

    Picked a single sentence from this post to remember, and a look at refinedclickpinghub gave me another to keep, content that produces memorable lines is doing more than just transferring information and the small selection of sentences I keep from each reading session is one of the actual returns I get from reading carefully.

    A nicely understated post that does not shout for attention, and a look at cleatbox maintained the same quiet quality, understatement is a stylistic choice that distinguishes serious writing from attention seeking writing and this site has clearly committed to the understated approach as a core editorial value rather than just a phase.

    A piece that handled the topic with appropriate weight without becoming portentous, and a look at maplevendor continued that calibrated seriousness, content that takes itself seriously without becoming pompous is something this site has clearly figured out and the balance shows up in every piece I have read across multiple sessions now.

    Closed my email tab so I could read this without interruption, and a stop at xernita earned the same protected attention, when content is good enough to defend against the usual digital distractions you know it deserves better than the half attention most online reading gets in a typical busy day.

    A welcome contrast to the loud takes that have dominated my feed lately, and a look at emberwharf extended that calm voice, content that arrives without yelling has become unusual in the modern attention economy and this site is one of the few places I have found that consistently delivers without raising its voice.

    Now noticing that the post benefited from being neither too short nor too long for its content, and a look at modernvaluescollective continued that calibration of length, sites that match length to content rather than padding to hit some target are sites that respect both their material and their readers and this site does both.

    Reply
  36. MiloWhawl

    Liked the balance between depth and brevity, never too shallow and never too long, and a stop at refinedclickpinghub kept the same balance going across the rest of the site, this is one of the harder skills in writing and the team here clearly has it figured out very well indeed across every page.

    Anyone curious about this topic would do well to start here, the foundation laid is solid, and a stop at basteclose would round out their understanding nicely, this is the kind of resource I would point a friend toward without hesitation if they asked me where to begin learning about anything in this area.

    Reading this in my last reading slot of the day was a good way to end, and a stop at finkgulf provided a satisfying close to the reading session, content that ends a day well rather than agitating it before sleep is the kind I value increasingly and this site fits that role for me consistently now.

    Felt energised after reading rather than drained, which is unusual for online content these days, and a look at everjumbo continued that good feeling, content that leaves you better than it found you is rare and worth bookmarking when you stumble across it for the first time today or any other day really.

    Looking back on this reading session it stands as one of the better ones recently, and a look at quickvendor extended that ranking, the informal ranking of reading sessions against each other is something I do mentally and this session ranks high largely because of this site and a couple of related pages here.

  41. Arnoldopilia

    Now considering carefully how to share this site with the right audience rather than broadcasting widely, and a look at modernvaluescollective extended that careful sharing impulse, content worth sharing carefully rather than spamming is content that has earned a higher kind of recommendation and this site has earned that careful shareability throughout pieces.

    Reply
  42. Shanebag

    Honestly this was a good read, no jargon and no padding, and a short look at cleatbox kept that same feel going which I really appreciated, the writer clearly knows the topic well enough to explain it without hiding behind big words or filler that often gets used to seem clever.

    Worth your time, that is the simplest endorsement I can give, and a stop at nookharbor extends that endorsement across the rest of the site, this is one of those increasingly rare places that delivers on what it promises rather than over selling the content and under delivering on substance every time which I find frustrating elsewhere.
