How to move static html site from Windows to Linux
- 1. Increase disk space.
- 2. Transform database from MsSQL to MySQL.
- 3. Add Mime types.
- 4. Add basic authentication.
- 5. Change file names.
- 6. Change CMS.
- 7. Recursion and memory optimization.
- 8. Enable SSI
- 9. Upload site Cloudflare CDN
- 10. Get free SSL certificate from Cloudflare
- 11. Enable SSL
- 12. My finally NGINX config
This site since creation was be hosted in Windows, because Window was be full free for hosting (Microsoft was send to anybody Windows key for MSDN subscription), but now Microsoft's degenerates has changed their policies and decide leave servers - move ASP.NET to Linux platform and decide to stop sending free key through MSDN. Therefore I decide follow this rules and also leave Windows in server.
For 20+ years my site become a huge, more than 120,000 pages and images.
So, this is list of steps I performed to do this task.
1. Increase disk space.
Now my site need about 100GB disk size, so fist step was to add additional space.
2. Transform database from MsSQL to MySQL.
To be honest this is not a static HTML-site, it has a lot of active ASP.NET extension, so first my step was be transform database from MsSQL to MySQL.
The simplest and fastest way to do this operation manually.
Firstly I have created DB inside MySQL, it's require only two commands - create database and user (grant permission):
This is more detail instruction Setup MariaDB on Ubuntu server (remote access, user privileges, upload database).
Than I have created DB structure I need - I have downloaded MS DB structure and convert SQL by http://www.sqlines.com/online.
Than I have copy data to Notepad++, create needed SQL Insert command and perform this command by MySQL.
Main point is turn off Autoincrement during data add processing.
SET FOREIGN_KEY_CHECKS=0; alter table `Forum` modify column `i` int(11) not null AUTO_INCREMENT; SET FOREIGN_KEY_CHECKS=1;
Next step is converting StoredProcedures. Unfortunately its possible only manually with a lot of attention for each procedures.
3. Add Mime types.
I have analyze my addition to mime.types as add it to /etc/nginx/mime.types.
4. Add basic authentication.
My site absolutely free, but has a couple folders with interesting book only for me. This books is not a huge secret, this is ordinary computer books and you can download it in thousands site from Inet, but I decide to protect it by password in my site.
So, this step is add basic AU to some folders. This is simple operations, in my case:
# sudo apt-get install apache2-utils # sudo htpasswd -c /var/www/vb-net.com/html/AndroidBook/Doc/.htpasswd 1 # cat /var/www/vb-net.com/html/AndroidBook/Doc/.htpasswd
Than I have add restriction to NGINX rules, in my case:
location /AndroidBook/Doc/ {
try_files $uri $uri/ =404;
auth_basic "Restricted Content";
auth_basic_user_file /AndroidBook/Doc/.htpasswd;
}
And restart NGINX.
# sudo service nginx restart
So, this step is pass too, this is my result config, and we will going ahead to main step.
5. Change file names.
Of course, Windows file names is case insensitive and Windows site can not be working in Linux without tricks. Various recipes, for example Using Apache htaccess file to change URL to lowercase, Convert and redirect URL in uppercase to lowercase using .htaccess, is not working in this case, because this redirect mean that you know filenames on disk. For example folder in disk has name LowCostAspNet, but inside page I use link to this page as LOWCOSTASPNET or lowcostaspnet. In this case to find out existing file in disk need 2 147 483 648 redirect with 32 chars in URL and 18 446 744 073 709 551 616 redirect with 64 letter in name. So, we need workable solution, I it describe below.
Continue reading - Linux console app (.NET Core, EF DB first, CamelCase file and dir rename, calc MD5, RegExpression, change and check link).
6. Change CMS.
Of course, my site has my own CMS to publish page, sync local Windows folder and remote, automatically create list of articles //www.vb-net.com/Articles/index.htm, automatically create forum topic for user comments for each page, automatically create RSS fields, create advertising (on top of pages you can see ticker to related topics) and many other futures. Of course, I don't manually add page to each this list, my CMS doing all needed operation automatically. And my CMS need to change too.
7. Recursion and memory optimization.
Most unexpected and interesting step was be memory optimization. I start this program in huge Linux machine with 50GB memory, therefore I don't thinking about memory at all, I thinking only my own time I mask spend to programming.
But I found additional time for optimization and during a couple of minutes I reduced consumption memory from 1300 MB with objects 200-300 MB.
to 75 MB with objects 0,1 MB (about 20 times !!!)
All I need to so radically reducing memory - I deleted recursion. I have replaces this code.
