LAMP and WordPress with HTTPS Certification Cloud Installation on Ubuntu

I have selected Ubuntu as OS platform to install my php, wordpress and mysql. It gave me lots of learning experience on Linux. Here is many steps I recorded during working on my 51sec.org blog site.

For Windows: WAMP and Wordpress Install on AWS Free Tier Windows 2012 R2
For Ubuntu: LAMP and WordPress Installation on Ubuntu

1. Basic Ubuntu Configuration (Not in Cloud)

john@ubuntu15:/etc/network$sudo /etc/init.d/networking restart

1.2. System Software Update

sudo apt-get update # Fetches the list of available updates
sudo apt-get upgrade # Strictly upgrades the current packages
sudo apt-get dist-upgrade # Installs updates (new ones)

#Following commands are not necessage. You can run them after intalled apache later.

sudo nano /etc/apache2/apache2.conf #add a single line "ServerName server_domain_or_IP "to the biottom of /etc/apache2/apache2.conf file to suppress a warning message.

sudo apache2ctl configtest
sudo systemctl restart apache2

Check Firewall to make sure allow inbound traffic for 80 and 443

2. Launch Instance in the AWS cloud

Please check my previous post :

Launch and Access Amazon AWS EC2 Instances

Rather than launch a 'Amazon Linux 2017.03.1 (HVM), SSD Volume Type Instance', you will need to launch 'Ubuntu Server 16.04 LTS (HVM), SSD Volume Type' AMI.

Note: At different region, AMI has different name. It is not same AMI name for all regions.

After logged into Ubuntu instance with username ubuntu and your private key, you will need to enter following commands to update your Ubuntu. Of course before that, you will set up your VPC, Subnets, internet gateway, default route, security group and public IP (EIP) properly.

sudo apt-get update   # Fetches the list of available updates
sudo apt-get upgrade   # Strictly upgrades the current packages
sudo apt-get dist-upgrade  # Installs updates (new ones)

3. Install LAMP

3.1. Install Apache

To install Apache you must install the Metapackage apache2. This can be done by searching for and installing in the Software Centre, or by running the following command.

sudo apt-get install apache2

3.2. Install MySQL (Optional for local MySql Server)

To install MySQL you must install the Metapackage mysql-server. This can be done by searching for and installing in the Software Centre, or by running the following command.

sudo apt-get install mysql-server
sudo mysql_install_db
sudo mysql_secure_installation

3.3. Install PHP

To install PHP you must install the Metapackages php5 and libapache2-mod-php5. This can be done by searching for and installing in the Software Centre, or by running the following command.

sudo apt-get install php libapache2-mod-php php-mcrypt php-mysql

3.4. Restart Server

Your server should restart Apache automatically after the installation of both MySQL and PHP. If it doesn't, execute this command.

sudo /etc/init.d/apache2 restart

3.5. Check Apache

Open a web browser and navigate tohttp://localhost/. You should see a message saying It works!

3.6. Check PHP

You can check your PHP by executing any PHP file from within /var/www/. Alternatively you can execute the following command, which will make PHP run the code without the need for creating a file .

john@ubuntu15:/etc/network$ php -r 'echo "\n\nYour PHP installation is working fine.\n\n\n";'

Your PHP installation is working fine.

ubuntu@ip-10-10-0-60:~$php -i

ubuntu@ip-10-10-0-60:~$sudo nano /var/www/html/info.php
<?php
phpinfo();
?>

Open you browser to open page: http://your_server_IP_address/info.php

4. Install Phpmyadmin (Optional)

$ sudo apt-get install phpmyadmin

follow configuration wizard to finish the configuration, such as choosing :

apache2 for your web server
yes for Configure database for phpmyadmin with dbconfig-common?
MySQL application password for phpmyadmin:
password for root user Password of the database's administrative user:

5. Install Wordpress
5.1 Install

cd ~
wget http://wordpress.org/latest.tar.gz
tar xzvf latest.tar.gz
sudo apt-get update
sudo apt-get install php5-gd libssh2-php

5.2 Configure

ubuntu@ip-10-10-0-60:~$ cd ~/wordpress
ubuntu@ip-10-10-0-60:~/wordpress$ cp wp-config-sample.php wp-config.php
ubuntu@ip-10-10-0-60:~/wordpress$ curl -s https://api.wordpress.org/secret-key/1.1/salt/
define('AUTH_KEY',         '/c|BO/-!OU8+unm:*{r.iZD/7.Ayge],.Unawgno^!%(=p@#U7fdW#3Q<hcq<&/e');

define('NONCE_SALT',       'C305sfDZGO5~J3XLDp|QLw2]4QYZ1B/#UM[pC6Lt+tvkBi]9pl-k^]e6Cw$,DM1(');
ubuntu@ip-10-10-0-60:~/wordpress$

ubuntu@ip-10-10-0-60:~/wordpress$ nano wp-config.php

Replace same section with above outputs in wp-config.php file.
5.3 Connect database
Change :

// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define('DB_NAME', 'wordpress');

/** MySQL database username */
define('DB_USER', 'wordpressuser');

/** MySQL database password */
define('DB_PASSWORD', 'password');

5.4 Copy Files to /var/www/html and Change Permission

This step will help you to set up right permission on the files and folder under /var/www/html. Else you will get a ftp credential prompt when you try to do updates or install a plugin

Wordpress Update FTP Error

sudo rsync -avP ~/wordpress/ /var/www/html/
cd /var/www/html

sudo chown -R ubuntu:www-data *
mkdir /var/www/html/wp-content/uploads
sudo chown -R :www-data /var/www/html/wp-content/uploads

Or:

cd /var/www/html

sudo chown www-data:www-data * -R 
sudo usermod -a -G www-data www-data

or:

sudo chown -R www-data:www-data /var/www
sudo find /var/www/ -type d -exec chmod 755 {} \;
sudo find /var/www/ -type f -exec chmod 644 {} \;

The other change we need to make is to set the method that WordPress should use to write to the file system. Since we've given the web server permission to write where it needs to, we can explicitly set the file system method to "direct". Failure to set this with our current settings would result in WordPress prompting for FTP credentials when we perform some actions. This setting can be added below the database connection settings, or anywhere else in the file:

/var/www/html/wp-config.php

. . .

define('DB_NAME', 'WP_DB');

/** MySQL database username */
define('DB_USER', 'WP_USER');

/** MySQL database password */
define('DB_PASSWORD', 'P@ssw0rd');

. . .

define('FS_METHOD', 'direct');

Save and close the file when you are finished.

5.5 Web Interface Installation

You will need to change default apache2 index.html file name.

johnyan_ca@wp-php:/var/www/html$ mv index.html apache.html

Use your browser to open http://your_server_IP_address/. You should get a wordpress wizard page. If you are still getting a Apache page, you may want to remove the file index.html under /var/www/html. That will make index.php become the first file to launch at site http://your_server_IP_address/.

Follow the wordpress wizard, you enter your site information. After complete it, your site is up and running.

6. Allow Remote Wordpress Connection to Mysql (Option)
6.1 Change MySql bind interface:

ubuntu@ip-10-1-1-50:/etc/mysql/mysql.conf.d$ netstat -ntlp | grep 3306
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
tcp        0      0 127.0.0.1:3306          0.0.0.0:*               LISTEN      -

ubuntu@ip-10-1-1-50:/etc/mysql/mysql.conf.d$ sudo vi mysqld.cnf

.....

# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
# bind-address          = 127.0.0.1
bind-address            = 0.0.0.0
#

.....

ubuntu@ip-10-1-1-50:/etc/mysql/mysql.conf.d$ sudo /etc/init.d/mysql restart
sudo: unable to resolve host ip-10-1-1-50
Restarting mysql (via systemctl): mysql.service.
ubuntu@ip-10-1-1-50:/etc/mysql/mysql.conf.d$ netstat -ntlp | grep 3306
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
tcp        0      0 0.0.0.0:3306            0.0.0.0:*               LISTEN      -

6.2 Allow a new user with remote machine name or public ip to access Mysql DB

ubuntu@ip-10-1-1-50:/etc/mysql/mysql.conf.d$ sudo mysql -u root -p mysql
sudo: unable to resolve host ip-10-1-1-50
Enter password: 
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

b. Stop Apache2 Service and Disable it Auto Run when rebooted

systemctl command – Only works on systemd based Ubuntu like version 16.04 LTS and above.
/etc/init.d/apache2 – A sys v init style script to start / stop / restart the Apache2 service under Debian or Ubuntu Linux.
service command – This command work in most Linux distributions including Debian and Ubuntu.
upstart command – Only works on certain version of Ubuntu.
apache2ctl command – This method should work on all Linux and Unix likeoperating systems.

$ lsb_release -a
$ sudo systemctl stop apache2.service
$ sudo systemctl status apache2.service

$ sudo apt-get install rcconf
$ sudo rcconf

7. Install free https certificate
https://letsencrypt.org/ provides free ssl/tls certificate for popular application platform using Certbot ACME client to simplify the whole process.

$ sudo apt-get update
$ sudo apt-get install software-properties-common
$ sudo add-apt-repository ppa:certbot/certbot
$ sudo apt-get update
$ sudo apt-get install python-certbot-apache

$ sudo certbot --apache

$ sudo certbot renew --dry-run

Note 1. It may need to run it a couple of times to get a new certificate installed. If dry-run appears to be working correctly, you can arrange for automatic renewal by adding a cron or systemd job to run 'certbot renew' automatically.

Note 2. If you are having multiple servers running for one domain, when you trying to use certbot to enable https for your apache, it may fail because of name resolution not matching your public ip. In that case, you will need delete you other public ip's A record from your DNS provider to make sure your public ip is match DNS name resolution.

8. Troubleshooting

8.1 Wordpress PermaLinks Issue

I met this issue when installed a new Ubuntu and wordpress. Here is the solution I found from this post:

There can be multiple things preventing the rewrite rule from working. My ubuntu server needed 3 things changed to get permalinks working.

In newer versions of apache2, you need to enable the module:

sudo a2enmod rewrite
sudo service apache2 restart

You may also need to modify the apache2.conf file.

sudo nano /etc/apache2/apache2.conf

Change your web directory override rule to AllowOverride All.

<Directory /var/www/>
    Options Indexes FollowSymLinks
    AllowOverride All
    Require all granted
</Directory>

After that, restart the service again.

The .htaccess file in the WordPress install directory needs to be owned or readable/modifiable by the webserver.

This can be accomplished by changing owner to www-data (usually the webserver user), or changing permissions.

sudo chown www-data /var/www/wordpress-install/.htaccess

sudo chmod 664 /var/www/wordpress-install/.htaccess
