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~
During a quiet evening reading session this provided just the right depth without being heavy, and a stop at buildyournextmove maintained the same evening appropriate weight, content with depth that does not exhaust the reader is content with editorial calibration and this site has clearly figured out how to be substantial without being demanding all the time.
If you scroll past this site without looking carefully you will miss something, and a stop at holdax extended that mild warning, the surface of the site does not advertise its quality loudly which means careful attention is required to recognise what is being offered here which is itself a kind of editorial signal.
Reading this slowly to absorb the structure, and the structure is doing real work alongside the words, and a look at startnextphase maintained the same architectural quality, when sentence shapes and paragraph rhythms reinforce the meaning rather than just transporting words you know you are reading skilled work today.
Came in confused about the topic and left with a much firmer grasp on it, and after jebbird I felt I could explain this to someone else without hesitation, that is the gold standard for any educational content and most sites simply fail to reach it ever which is unfortunate but true.
Reading this with my morning coffee turned into reading the related posts with my morning coffee, and a stop at learnandrefine stretched the morning further, content that pulls breakfast into a reading session rather than just accompanying it is content that has earned a higher claim on my attention than the average article does.
Worth pointing out that the post avoided the temptation to summarise everything at the end, and a look at discovercreativegrowth 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.

Really thankful for posts that respect a reader’s time, this one does, and a quick look at seolift was the same, no need to scroll through endless intros just to get to the actual content, that approach alone is enough reason to come back here regularly for the kind of writing offered.
Comfortable reading experience throughout, no jarring tone shifts and no awkward formatting, and a look at startwithpurposefulsteps kept that smooth feel going, the kind of editorial polish that goes unnoticed when present but glaring when absent is something this site has clearly invested in across the broader content as well which deserves recognition.

Recommend this to anyone who values clear thinking over flashy presentation, and a stop at surgesorrel continued in the same understated way, this site has its priorities in the right place which makes it worth supporting through repeat visits and recommendations rather than just one passing read today before moving on quickly elsewhere.

Coming to this with low expectations and being pleasantly surprised by the substance, and a stop at createvisionforward continued exceeding expectations, the recalibration of expectations upward across multiple positive readings is one of the actual rewards of careful browsing and this site is providing that recalibration at a steady rate apparently.
Honestly enjoyed reading this more than I expected to when I first clicked through, and a stop at buildactionableprogress 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.

Skimmed first and then went back to read carefully, and the careful read paid off in places I had missed, and a stop at inobrat got the same treatment, the rare site whose content rewards a second pass is content I want more of in my regular rotation rather than disposable single read articles.

Reading this felt productive in a way most internet reading does not, and a look at exploreideaswithpurpose continued that productive feeling, sometimes the open web feels like a waste of time but sites like this remind me why I still bother to look around rather than retreating to old reliable sources for everything I need.
Thank you for keeping the writing honest and the points easy to verify against your own experience, and a stop at createprogressmapping reflected the same approach, no exaggeration just steady useful content that I can take with me into my own work without second guessing every sentence I happen to read here.
Took the time to read the comments on this post too and they were also worth reading, and a stop at hurbug suggested the community quality matches the content quality, when the conversation around a piece is as good as the piece itself you know you have found a real corner of the internet.

Reading this slowly because the writing rewards a slower pace, and a stop at buildyournextmove 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.
Worth saying this site reads better than most paid newsletters I have tried, and a stop at createimpactsteps confirmed that comparison, the bar for free content is often lower than for paid but this site clears the paid bar consistently and that says something about the editorial approach behind the work being published here regularly.

Glad I gave this a chance instead of bouncing on the headline, and after discovercreativegrowth 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.

Probably the kind of site that should be more widely read than it appears to be, and a look at bulkingbayou reinforced that quiet wish, the gap between a sites quality and its apparent reach is sometimes large and that gap exists for this site in a way that makes me want to mention it more.
Really like that the writer trusts the reader to follow simple logic without restating every previous point, and a stop at buildsustainableprogress 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.
Liked the post enough to read it twice and the second read found new things, and a stop at learnandscale similarly rewarded the second look, content with hidden depths that only reveal themselves on careful rereading is the rare kind that earns lasting respect rather than fleeting first impressions only briefly held.
Probably worth setting aside a longer block to read more carefully than I can right now, and a stop at buildforwardthinking confirmed the longer block plan, the impulse to schedule dedicated time for a sites archive is itself a measure of trust and this site has earned that scheduling impulse from me clearly today actually.
Thanks for laying this out in a way that someone newer to the topic can follow, and a stop at holdax kept that accessibility going, writing that meets readers at different experience levels without condescending is hard to do well and the writers here have clearly thought about who they are writing for.
Now feeling something close to gratitude for the fact this site exists, and a look at buildsustainablemomentum extended that gratitude, the rare site that produces this kind of response is the rare site worth defending in conversations about whether the modern internet is still capable of producing genuinely valuable independent content for serious adults.
A piece that demonstrated competence without performing it, and a look at seolift 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 gave me a small framework I expect to use going forward, and a stop at buildsmartdirection extended that framework, content that produces transferable mental models rather than just specific facts is content with multiplicative value and this site is providing those models at a rate that justifies extra attention from me regularly.
Came in skeptical of the angle and left mostly persuaded, and a stop at jebbird pushed me a bit further in the same direction, content that can move a critical reader by argument rather than rhetoric is rare and worth pointing out because it indicates real substance underneath the surface presentation here.
Honestly enjoyed not being sold anything for the entire duration of the post, and a look at createimpactsteps kept that pleasant absence going across more pages, content that exists for its own sake rather than as a funnel to a paid product is increasingly rare and worth supporting where I can find it.
Refreshing tone compared to the dry corporate posts on similar topics, and a stop at explorefreshgrowthideas carried that personality through nicely, you can tell when a real person is behind the writing versus a content team chasing metrics and this site definitely falls into the former category clearly across what I have seen.
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 bulkingbayou 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.
Picked something concrete from the post that I will use immediately, and a look at buildsustainableprogress added another concrete piece, content that produces immediately useful output rather than just abstract appreciation is content that earns its place in my regular rotation without needing any further evaluation from me at this point honestly.
Now adding this site to a small mental group of recommendations I keep ready for specific kinds of inquiries, and a stop at startthinkingclearly extended the recommendation readiness, content that I can confidently point friends and colleagues toward in specific contexts is content with real social utility and this site has that utility clearly.

Adding this to my list of go to references for the topic, and a stop at exploreideaswithpurpose confirmed the rest of the site deserves the same, definitely the kind of resource that earns its place rather than getting forgotten the moment the next interesting article shows up in my feed somewhere else on the web.
Picked this for my morning read because the topic seemed worth the time, and a look at learnandscale 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.
Saving the link for sure, this one is a keeper, and a look at startnextlevelgrowth confirmed I should bookmark the entire site rather than just this page, the consistency across what I have seen so far suggests there is a lot more here worth coming back for soon when I have more time.
Now noticing that the post benefited from being neither too short nor too long for its content, and a look at explorefreshthinkingnow 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.
If patience for careful reading is rare these days finding sites that reward it is rarer still, and a stop at buildsustainablemomentum 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.
Skimmed first and then went back to read carefully, and the careful read paid off in places I had missed, and a stop at exploreideaswithpurpose got the same treatment, the rare site whose content rewards a second pass is content I want more of in my regular rotation rather than disposable single read articles.
Got something practical out of this that I can apply later this week, and a stop at buildsmartdirection 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.
