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~
Bookmark folder reorganised slightly to make this site easier to find, and a look at discovernewmomentum earned the same accessibility upgrade, the small organisational moves I make for sites I expect to return to often are themselves a signal of how much I trust them and this site triggered those moves naturally.
Came away with some new perspectives I had not considered before, and after hurbug those ideas felt more complete, the kind of content that stays with you a little while after reading rather than slipping out the moment you switch tabs and move on with your day to whatever comes next.
Glad to find a site whose links lead somewhere worth going rather than back to itself for SEO juice, and a stop at findgrowthopportunitiespath kept that generous outbound feel, citing other peoples work with real respect rather than just for ranking signals is a sign of an honest operation worth supporting going forward.
Thank you for not assuming the reader already knows everything, the explanations meet me where I am, and a look at learnandoptimizepath did the same, that consideration is what makes a site feel welcoming rather than gatekeepy which is sadly the default mood across the modern web today for most subjects covered.
Glad to find a site whose links lead somewhere worth going rather than back to itself for SEO juice, and a stop at inobrisk kept that generous outbound feel, citing other peoples work with real respect rather than just for ranking signals is a sign of an honest operation worth supporting going forward.
Now wishing I had found this site sooner, and a look at explorefreshgrowthideas extended that mild regret, the calculation of how many years of good content I missed by not finding the right sources earlier is one I try not to make too often but it does come up sometimes when I find sites this good.
Now feeling confident enough in this site to use it as a reference point for evaluating others on the same topic, and a look at startthinkingclearly continued the comparison friendly quality, sites that serve as quality benchmarks for their topic are precious and this one has clearly become a benchmark for me on this particular subject area.
Now noticing the careful balance the post struck between confidence and humility, and a stop at startwithpurposefulsteps maintained the same balance, finding the line between asserting and admitting is hard and this site has clearly developed the calibration to walk that line consistently which produces a more persuasive reading experience for me.
Reading this in the time it took to drink half a cup of coffee, and a stop at syrupserif fit naturally into the second half, content that respects the rhythms of a typical morning is content with practical fit and this site has the kind of length and pacing that works for the way I actually read.
Reading this slowly to give it the attention it deserved, and a stop at explorefreshthinkingnow earned the same slow read, choosing to read slowly is a small act of respect for content quality and very few sites earn that respect from me but this one did so without any explicit ask which is the cleanest way.
Quietly the writers approach to the topic differs from the dominant takes I have been encountering, and a stop at startnextlevelgrowth extended that distinctive approach, content that maintains a different perspective without explicitly arguing against the dominant ones is content with confident editorial identity and this site has that confidence throughout pieces.
Solid post, the structure is easy to follow and the language stays simple even when the topic gets a bit more involved, and a look at exploreideaswithpurpose kept that same standard going, so I left feeling like the time spent here was actually worth something for once which is rare lately.

Reading carefully this time rather than scanning, and the depth shows up in places I missed first time around, and a look at createimpactjourney rewarded the same careful approach, content that holds up to multiple reads is content I want more of in my regular rotation rather than disposable scroll fodder daily.
Genuinely good work, the kind that holds up over multiple readings without losing its appeal, and a stop at learnandoptimizepath kept that going, definitely a site I will be returning to and probably mentioning to others who work in or care about this particular area of interest today and in coming weeks.
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 findgrowthopportunitiespath 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.
Most posts I read end up forgotten within a day but this one is sticking, and a look at growyourcapabilities extended that lingering effect, content that survives the immediate moment of reading rather than evaporating is content with genuine retention quality and this site has been producing memorable pieces at a rate notable across my reading.
Strong recommendation, anyone interested in this topic owes themselves a visit, and a stop at parcelparadise extends that recommendation across more of the site, this is the kind of resource that makes me more optimistic about the state of the open web than I usually am these days actually for once which is genuinely refreshing.
Now considering carefully how to share this site with the right audience rather than broadcasting widely, and a look at startnextchapter 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.
Granted my mood today might be elevating my reading experience but I still think this is genuinely good, and a stop at inobrisk reinforced that even discounted assessment, controlling for the mood adjustment that affects content perception this site still reads as substantively above average across multiple pieces I have read carefully today.

Approaching this site through a casual link click and being surprised by what I found, and a look at discovernewmomentum extended the surprise, the rare experience of stumbling into excellent independent content rather than predictable mediocrity is one of the actual remaining pleasures of casual web browsing and this site provided it cleanly.
Reading this gave me confidence to make a decision I had been putting off, and a stop at startyournextphase reinforced that confidence, content that translates into action in my own life rather than just informing it is content with the highest practical value and this site is generating that action level utility for me lately.

Now thinking about how this post will age over the coming years, and a stop at seomagnet suggested the same durability, content built to age well rather than to capture the attention of the moment is content with a different kind of value and this site has clearly chosen the long horizon over the short one.

Skipped the comments to avoid spoilers and came back later to find them genuinely worth reading, and a stop at startwithpurposefulsteps 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.
Reading this in pieces over a coffee break and finding it consistently rewarding, and a stop at learnandprogresssteadily 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.
The lack of unnecessary jargon made the post accessible without sacrificing accuracy, and a look at createimpactjourney 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.
Came across this through a roundabout path and now it is on my regular rotation, and a stop at holpod sealed that decision, the open web still produces serendipitous discoveries when you let the citations and references guide you rather than relying purely on algorithmic feeds for new content recommendations always.
Really appreciate the lack of pop ups, modals, cookie banners stacking on top of each other, and a quick visit to growyourcapabilities confirmed the same clean approach across the rest of the site, technical decisions about user experience are part of what makes content actually pleasant to engage with for sure.

Now adding the writer to a small mental list of voices I want to follow, and a look at discovercreativepaths reinforced that follow intention, the few writers whose work I actively track are writers who have demonstrated sustained quality and this writer has clearly demonstrated that sustained quality across the pieces I have sampled here today.
Most of the time I feel the open web is in decline and then I find a site like this, and a stop at createpositiveoutcomes reinforced that mood lift, the cumulative effect of finding occasional excellent independent content versus the cumulative effect of finding mostly mediocre content is real for the long term reader maintaining web habits today.
Felt the writer respected me as a reader without making a show of doing so, and a look at startnextchapter continued that quiet respect, this is the kind of small but meaningful detail that separates the sites I bookmark from the ones I close after a single skim and never return to again no matter how interesting the headline.
If I had to summarise the editorial sensibility of this site in a few words it would be careful and human, and a look at buildlongtermstrength extended that summary feeling, capturing the essence of a sites approach in brief is hard but this site has a clear enough identity that the summary comes naturally enough.
Picked this for my morning read because the topic seemed worth the time, and a look at startpurposefuljourney 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.

Worth pointing out that the writer made the topic feel more interesting than I had been expecting, and a look at syrupserif continued that elevation effect, content that improves the apparent quality of its subject through skilled treatment is doing something real and this site has clearly developed that kind of editorial alchemy throughout.

Now appreciating the way the post avoided the temptation to be longer than necessary, and a look at startyournextphase continued that lean approach, content with the discipline to stop when finished rather than padding for length is content that respects both itself and its readers and this site has that disciplined editorial culture clearly throughout.
Grateful for posts like this one, they remind me there are still places online run by people who care about quality, and a look at learnandprogresssteadily reflected the same standards, you can tell the difference between content made for readers and content made just for search engines today and this is the former.
Skimmed first and then went back to read carefully, and the careful read paid off in places I had missed, and a stop at buildclarityforward 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.
If the topic interests you at all this is a place to spend time, and a look at jebbrood 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.
Honestly thank you to whoever wrote this because it scratched an itch I had not quite been able to articulate, and a stop at startwithclearfocus kept that satisfying feeling going, the kind of writing that meets unspoken needs is special and this site clearly has writers who understand their readers more than most do today.
Considered alongside other sources I have been reading this one consistently rises to the top, and a stop at seomagnet maintained that top ranking, the informal ongoing comparison between sources is something I do whenever reading on a topic and this site keeps coming out near the top of those comparisons over many sessions.
Just sat with this for a bit longer than I usually would because the points are worth thinking about, and after startpurposefuljourney I had even more to chew on, the kind of post that nudges your thinking forward without forcing the issue is something I have always appreciated in good writing online.
