# Resources for Setting Up New Server
[Upcloud](https://upcloud.com/pricing/) and [A2hosting](https://www.a2hosting.com/vps-hosting) are two fantastic VPS hosting.
## SETTING UP NEW SERVER ON A2 HOSTING
{% hint style="info" %}
This is for CentOS 7 on A2server

A2 hosting was chosen because of:

* Optional, here is another way the step above can be set up (Note: this website set up a bit different than the one above, specifically, the above website use /etc/httpd/conf.d/ instead of /etc/httpd/sites-enabled):
* danielromogroup.com and other sites on this server has been set up using /etc/httpd/conf.d/*site.com*.conf

### 10. Force using https access using .htaccess:
*
*
### 11. Configure PHP to read .htaccess file on a CentOS 7 server
We need to modify the `httpd.conf` file:
```bash
vi /etc/httpd/conf/httpd.conf
```
In this file: after ``, modify `AllowOverride None` to `AllowOverride Options`.
Save the file (hit Esc, type `:wq` and then Enter)
Restart httpd service:
```bash
systemctl restart httpd
```
### 12. Dreamweaver:

*
*
*
### 14. MySQL/MariaDB

### 15. Installing phpMyAdmin
*
*
*
*
*
### 16. Working with tar files
*
*
*
*
### 17. Setting up multiple websites with multiple domains on the same server
* On current A2 hosting, the server config can be found in /etc/httpd/conf/httpd.conf
*
* Setting up multiple Let’sEncrypt certificates for multiple hosts on the same server: (this is for Ubuntu)
* For CentOS, generate two #.conf files in /etc/httpd/conf.d/. For example: /etc/httpd/conf.d/site1.com.conf and /etc/httpd/conf.d/site2.com.conf. Each conf file is the apache set up for the site. Example of the content of site2.com.conf:
```bash
DocumentRoot /var/www/html/site2.com
ServerName server.site2.com
ServerAlias site2.com www.site2.com
```
* * After that use “/usr/local/sbin/certbot --apache -d example.com -d [www.example.com](http://www.example.com/)” . The content of site2.com.conf file will be automatically changed. Here is example of the content of site2.com.conf after running the “certbot-auto…”
```bash
DocumentRoot /var/www/html/site2.com
ServerName server.site2.com
ServerAlias site2.com www.site2.com
DocumentRoot /var/www/html/site2.com
ServerName server.site2.com
ServerAlias site2.com www.site2.com
SSLCertificateFile /etc/letsencrypt/live/site2.com/cert.pem
SSLCertificateKeyFile /etc/letsencrypt/live/site2.com/privkey.pem
Include /etc/letsencrypt/options-ssl-apache.conf
SSLCertificateChainFile /etc/letsencrypt/live/site2.com/chain.pem
```
* Read here for more info about a set up a conf file for SSL certificate:
### 18. Working with WordPress

*
* Multiple sites (using WordPress) installation:

* Uninstall Wordpress:
* To use 1-click update on Wordpress, you need
* Wordpress folder (in this case /var/www/html/baylorcpritlab.com) to be owned by apache:apache with 755 permission
* To secure Wordpress, all **folders** inside the baylorcpritlab.com should have 755 persmission and all **files** should have 644 permission
