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~
Refreshing to read something where the words actually mean something instead of filling space, and a stop at createimpactefficiently kept that going, the writing here trusts the reader to follow along without endless repetition or constant reminders of what was already said earlier in the post which I appreciate.
Started this morning and finished at lunch with a small sense of having spent the time well, and a look at mindfullifestylemarket extended that satisfaction into the afternoon, content that fits naturally into the rhythm of a working day rather than demanding a dedicated reading block is increasingly the kind I prefer.
Decided to set a calendar reminder to revisit, and a stop at humvat extended that revisit list, calendar entries for content are a level of commitment I rarely make but when I do they signal a higher regard than a simple bookmark and this site has earned that calendar tier of relationship from me today.
Honest opinion is that this is the kind of post that builds long term trust with readers, and a look at learnandaccelerate reinforced that perception, the slow accumulation of trust through consistent quality is the only sustainable way to build a real audience and this site is clearly playing that long game.
Just wanted to drop a quick note saying this was a useful read on a topic I have been circling, no fluff, and a stop at hewzap added a few extra points that fit the same simple style which makes the whole site feel coherent rather than thrown together by many different writers with different goals.
Top quality material, deserves more attention than it probably gets, and a look at daheko 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.
Loved the writing voice here, friendly without being fake and confident without being arrogant, and a stop at learnsomethinguseful carried the same tone forward, the kind of personality that makes a reader feel welcome rather than lectured at which is a balance plenty of writers struggle to find no matter how long they have been at it.
Honestly impressed by the consistency of voice across what I have read so far, and a quick visit to findyournextchallenge continued that consistent feel, when a site reads like one careful person rather than a committee the experience is more rewarding for the reader who notices these subtle editorial details over time.

Reading this in the gap between work projects was a small but meaningful break, and a stop at trenchvinca extended that gentle reset, content that provides genuine refreshment rather than just distraction during work breaks is content with a particular kind of utility and this site fits that role for me reliably during work days.
Pass this along to colleagues if the topic comes up, the framing here is sensible, and a stop at subletviper adds more useful angles to share, the kind of content that improves conversations rather than just feeding them is what makes a resource genuinely valuable in professional contexts going forward over time and across project boundaries too.

Thank you for the genuine effort here, it shows in every paragraph and not just the headline, and after my visit to createimpactefficiently I was sure this site cares about getting things right rather than chasing clicks, which is the main reason I will come back later this week to read more.
Bookmark added in three places to make sure I do not lose the link, and a look at learnstepbystep got the same redundant treatment, sites I am afraid to lose are the rare keepers and this is clearly one of them based on what I have read so far across this and a couple of related posts.

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 explorefreshdirections I am sure this site treats its readers well, no flashy tricks just useful content done right which is honestly all I want online.
Thanks for the breakdown, it gave me a clearer picture of something I had been confused about for a while now, and a stop at buildyourvisionnow closed the remaining gaps in my understanding nicely, no need to hunt around twenty other articles to put the pieces together which is a real time saver.
A piece that reads as if the writer trusted readers to fill in obvious gaps, and a look at jadburst continued that respectful approach, content that does not over explain what the reader can infer is content that respects intelligence and this site has clearly chosen to write to capable readers rather than to the lowest common denominator.
Definitely returning here, that is decided, and a look at learnandaccelerate only made the case stronger, this is one of those rare websites that rewards regular visits rather than feeling stale after the first read which is something I cannot say about most of the places I bookmark today across all my topics.
This actually answered the question I had been searching for, and after I checked javyam I had a few more pieces I had not realised I needed, that is the sign of a site that knows what its readers want before they even know how to ask it which is impressive.
Took a chance on the headline and was rewarded, and a stop at bexedge kept the rewards coming as I clicked through, the kind of place where every link leads somewhere worth the click is a small luxury on the modern web where so many sites are mostly empty calories disguised as content.

Just want to recognise that someone clearly cared about how this turned out, and a look at vaultscript confirmed that care extends across the broader site, you can feel the difference between content shipped to hit a deadline and content released because the writer was actually proud of the result for once.

Good post, the kind that respects the reader by getting to the point quickly without skipping the details that matter, and a short look at growwithconfidencepath confirmed that approach is consistent across the site which is rare to find online these days, definitely a place I will return to soon.

Took the time to read every paragraph rather than skimming for the punchline, and a quick visit to humvat earned the same careful attention from me, that is the highest signal I can give about content quality because my default mode is rapid scanning rather than deliberate reading on most pages.

Reading this on a slow Sunday and finding it perfectly suited to a slow Sunday read, and a quick stop at explorefreshdirections kept the same gentle pace, content that fits the mood of the moment is something I notice and remember and this site has the kind of pace that suits relaxed reading sessions especially well.
Now wondering how the writers calibrated the level of detail so well, and a stop at tokensaffron continued the same calibration, the right level of detail is one of the harder editorial calls in any piece and this site has clearly developed an instinct for it through what I assume is years of careful practice publicly.

Worth pointing out that the writing reads as confident without being defensive about it, and a look at jadburst extended that secure tone, content that does not pre emptively argue against imagined critics has a different quality from defensive writing and this site reads as written from a place of real ease.
Reading this slowly to absorb the structure, and the structure is doing real work alongside the words, and a look at hewzap 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.
Reading this brought back an idea I had set aside months ago, and a stop at premiumlivingmarketplace added more substance to that idea, content that revives dormant projects in my own thinking is content with serious creative value and this site is contributing to my own work in ways I had not expected when first clicking through.
Looking back on this reading session it stands as one of the better ones recently, and a look at subletviper 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.
Found a couple of useful angles in here I had not considered before reading carefully, and a quick stop at buildyourvisionnow added more, this is one of those sites where the value compounds the more you read rather than peaking at one viral post and then offering nothing else of substance afterwards which is common.
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 deoblob 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.
Now setting aside time on my next free afternoon to read more from the archives, and a stop at growwithconfidencepath confirmed that time will be well spent, the rare site whose archive deserves a dedicated reading session rather than just casual sampling is the kind of resource worth scheduling around and this one qualifies clearly.

The lack of unnecessary jargon made the post accessible without sacrificing accuracy, and a look at buildsmarthabits continued in the same accessible style, technical topics often hide behind specialised vocabulary but here the writer trusts the reader to keep up with plain language and that trust pays off nicely throughout the entire post.

Skimmed first and then went back to read carefully, and the careful read paid off in places I had missed, and a stop at vaultscript 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.
A small thank you note from me to the team behind this work, the post earned it, and a stop at teapotshrine 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.
During my morning reading slot this fit perfectly into the routine, and a look at startbuildingclarity extended that perfect fit into the rest of the routine, content that matches the rhythm of how I actually read rather than demanding accommodation from my schedule is content well calibrated to its likely audience and this site has it.
