### SSH Into Server
Be in the foler that the certificate is in or else write the path to certificate.
Dont include '[ ]'

CD into folder containing SSH Key

```
ssh bitnami@[ip-address] -i [name-of-certificate]
```

If you get an error about the certificate being insecure, cd into the directory that the certificate is located in and run the following:

```
sudo chmod 600 [name-of-the-cert]` (Remove the brackets when writing in terminal)
```

Then try the first instruction again.

### Check Admin Password

```
cat bitnami_application_password
```
### Accessing PhpMyAdmin on Linux and Mac OSX

1. `ssh -N -L 8888:127.0.0.1:80 -i KEYFILE bitnami@SERVER-IP`

2. Then go to: http://127.0.0.1:8888/phpmyadmin/

3. Login with username: root and password is the bitnami application password in the bitnami folder on the server. FTP into the server to get it. It will be different for every instance.

4. Once in the database, create a new database for wordpress and a user for the database

### Permissions Overall (Must do to get image uploading, plugin updates)

Every Folder in wp-content ( Root ) 775 bitnami:daemon

cd into the root directory

```
sudo chown -R daemon:bitnami htdocs/
sudo find htdocs/ -type d -exec chmod 775 {} \;
sudo find htdocs/ -type f -exec chmod 664 {} \;
```

### Email Setup MX Records
Emails do not use www in their domain lookup, so you must specify the root domain

- Type MX
- Subdomain: (no www) - domain.com
- Priority: 1
- Destination: Mail Server

### Start/Stop Web Server
Stop Server `sudo /opt/bitnami/ctlscript.sh stop`

Start Server `sudo /opt/bitnami/ctlscript.sh start`

### Caching during development
By default lightsail has a pretty hardcore cache which is one of the reasons its so fast. During development this is annoying because the files take a while to refresh after a new upload to the ftp. During development edit line 1906 of the php.ini file to have the opcache.enable=0 instead of 1. Once going live this should be turned back on with a value of 1. 

Location of php.ini
`/opt/bitnamii/php/etc/php.ini`

Location of httpd.conf
`/opt/bitnami/apache2/conf/httpd.conf`

comment out lines 526 and 527

`Include conf/pagespeed.conf`

`Include conf/pagespeed_libraries.conf`

Now restart the Server

### Lets Encrypt SSL Setup
