# Resources for Setting Up New Server
## SETTING UP NEW SERVER ON A2 HOSTING
{% hint style="info" %}
This is for CentOS 7 on A2server
{% endhint %}
A2 hosting was chosen because of:
### 1. Setting up LAMP stack
{% embed url="" %}
### 2. Accessing your account:
{% embed url="" %}
* SSH set up:
*
*
* SSH using keys:
*
* Possible error while setting up ssh key:
*
* Disable SSH login for root (recommended):
* FTP:
* SCP:
### 3. Back-up data (document from A2), also should see Khoi’s document on OE:
*
*
* To make a script to delete files older than X days when there is less than XGB left, see this:
*
* To monitor uptime for the server, use:
* Rclone is used to automatically backup file toGoogle Drive account:
* Install:
* Configuration for Google Drive: or
* Usage:
* For Rclone filtering:
* To back up the whole VPS, follow this:
*
* This is more options:
* Modified script as this:
```bash
tar cvpzf /backups/backup-$(date +\%Y\%m\%d).tgz --exclude=/proc --exclude=/lost+found --exclude=/backups --exclude=/dev --exclude=/sys --exclude=/boot/grub --exclude=/etc/fstab --exclude=/etc/sysconfig/network-scripts/ --exclude=/etc/udev/rules.d/70-persistent-net.rules --exclude=/home/some_other_folders

### 7. Obtaining free SSL certificate (from Let’sEncrypt):
* First: Make sure you have the *your\_site.com*.conf file inside /etc/httpd/conf.d. Following the following website: ; For more elaborate see:
* 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
* This is a good installation for Certbot Let’sEncrypt (ignore the multiple certificate setting):

{% embed url="" %}
### 9. Creating groups, users; Assigning passwords:
*
* Assinging password and require immediate pass change after log in:
* Add Linux users to a group:
*
*
### 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:
* Creating Template:
*
*
*
*
### 13. Setting up firewall for CentOS 7:
* **DON’T FORGET TO OPEN PORT 7822 FOR SSH WHILE USING A2 SERVER**
* If forgot to open port 7822, follow this link:
*
*
*
### 14. MySQL/MariaDB
* Error that need to change packet size:
### 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
```

### 18. Working with WordPress
* Initial Install:

* WP security, from A2 hosting:
* UpdraftPlus Plugin is used to back up WordPress. To restore Wordpress
* Create a fresh install of wordpress as in the link above

* 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
