To move a MySQL data directory to another directory:

# mysql -e "SELECT @@datadir;"
+-----------------+
| @@datadir       |
+-----------------+
| /var/lib/mysql/ |
+-----------------+

# systemctl stop mysql
# systemctl status mysql

# vim /etc/mysql/mysql.conf.d/mysqld.cnf
datadir         = /home/mysql

# vim /etc/apparmor.d/tunables/alias
alias /var/lib/mysql/ -> /home/mysql/,

Note: We need to tell AppArmor to let MySQL write to the new directory by creating an alias between the default directory and the new location.

Note: If you skipped the AppArmor configuration step, you would see the following error message:

Job for mysql.service failed because the control process 
exited with error code. See "systemctl status mysql.service" 
and "journalctl -xe" for details.

# systemctl restart apparmor
# systemctl restart mysql

To move the existing to MySQL directory to /home:

# rsync -av /var/lib/mysql /home

Or, you can run the following commands to initialize the MySQL data directory:

# mkdir /home/mysql \
&& chown mysql:mysql /home/mysql \
&& chmod 700 /home/mysql \
&& mysqld --initialize-insecure

Note: This option is used to initialize a MySQL installation by creating the data directory and populating the tables in the mysql system database.

Note: If you use --initialize, the random initial password is stored at: tail -n 1 /var/log/mysql/error.log.

Note: You can also start mysqld with --skip-grant-tables to access the database and change the password.

# systemctl start mysql && systemctl status mysql

Login MySQL with the above commands if you initialized MySQL data directory with --initialize-insecure option.
# mysql -u root --skip-password
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';

Check the current MySQL data directory:

# mysql -e "SELECT @@datadir;"
+--------------+
| @@datadir    |
+--------------+
| /home/mysql/ |
+--------------+

To change the root password if you did not know the current root password:

# vim /root/tmp/mysql-init.txt
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY 'YourPassWordHere' WITH GRANT OPTION;
GRANT SUPER ON *.* TO 'root'@'localhost';
FLUSH PRIVILEGES;

# mysqld --init-file=/root/tmp/mysql-init.txt

Use RAM-DISK for tmpdir:

# mysql -e "SHOW GLOBAL STATUS LIKE 'Created_tmp%tables';"
# mysql -e "SHOW GLOBAL VARIABLES LIKE '%table_size';"

# mkdir -p /mnt/ramdisk
# mount -t tmpfs -o size=512M tmpfs /mnt/ramdisk
# chown mysql:mysql /mnt/ramdisk

# id mysql

uid=123(mysql) gid=130(mysql) groups=130(mysql)

# vim /etc/fstab

tmpfs           /mnt/ramdisk     tmpfs   rw,uid=123,gid=130,mode=1770,size=512M    0       0

Note: You need to change the uid and gid of MySQL.

# mysql -e "SHOW GLOBAL VARIABLES LIKE 'tmpdir';"

# vim /etc/apparmor.d/local/usr.sbin.mysqld

/mnt/ramdisk rw,
owner /mnt/ramdisk/** rwkl,

Note: The first line gives read and write access to the directory, the second line gives read, write, lock(k) and link(l) access to all the files and the directories inside the directory owned by the mysql user.

# vim /etc/mysql/mysql.conf.d/mysqld.cnf

[mysqld]
tmpdir      = /mnt/ramdisk

# systemctl restart apparmor.service
# systemctl restart mysql.service

Install PHP7.1:

# command -v add-apt-repository >/dev/null 2>&1 \
|| { echo >&2 "add-apt-repository is not installed. I will install it for you"; apt-get install python-software-properties; }

# add-apt-repository -y ppa:ondrej/php
# apt-get update

# apt-cache policy php7.1

# apt-get install php7.1-fpm
# apt-get install php7.1-xml php7.1-curl php7.1-zip php7.1-gd php7.1-bcmath php7.1-intl php7.1-mbstring php7.1-mcrypt php7.1-mysql

;listen = /run/php/php7.1-fpm.sock
listen = 127.0.0.1:9000

Note: You can choose to use either a Unix socket (for local access only) or TCP socket (for the other server on the network to access).

Set up xdebug:

# vim /etc/php/7.1/fpm/php.ini

[Xdebug]
xdebug.default_enable=1
xdebug.remote_enable=1
xdebug.remote_handler=dbgp
xdebug.remote_host=localhost

date.timezone = America/Vancouver
display_errors = On
display_startup_errors = On
error_reporting = E_ALL
error_log = /var/log/php_errors.log

List all the installed PHP packages:

# dpkg -l | grep php| awk '{print $2}' |tr "\n" " "

Show the available package version:

# apt-cache search php
# apt-cache policy php

Install the specific package version:

# apt-get install php7=7.0+35ubuntu6

Note: You can look up old versions of packages at their site http://www.debian.org/distrib/packages

Install older version of PHP (PHP5.6):

# add-apt-repository ppa:ondrej/php

# apt-get update

# apt-get install php5.6-fpm

# apt-get install php5.6-gd php5.6-intl php5.6-json php5.6-mbstring php5.6-mcrypt php5.6-mysql php5.6-opcache php5.6-xml

# a2disconf php7.0-fpm.conf
# a2enconf php5.6-fpm.conf

# systemctl restart apache2.service

Install Apache2.4:

# command -v add-apt-repository >/dev/null 2>&1 \
|| { echo >&2 "add-apt-repository is not installed. I will install it for you"; apt-get install python-software-properties; }

# add-apt-repository -y ppa:ondrej/apache2
# apt-get update

# apt-cache policy apache2

# apt-get install apache2

Enable the following modules to talk to PHP:

# cat /etc/apache2/conf-available/php7.1-fpm.conf

# a2enmod proxy proxy_fcgi rewrite setenvif ssl
# a2enconf php7.1-fpm.conf

If your apache is talking to PHP through a TCP socket (127.0.0.1:9000) instead of a Unix socket (/run/php/php7.1-fpm.sock), you will need to modify the following line:

# vim /etc/apache2/conf-available/php7.1-fpm.conf
# Define a matching worker.
    # The part that is matched to the SetHandler is the part that
    # follows the pipe. If you need to distinguish, "localhost; can
    # be anything unique.
    <Proxy "fcgi://localhost/" enablereuse=on max=10>
    </Proxy>
    <FilesMatch ".+\.ph(ar|p|tml)$">
        #SetHandler "proxy:unix:/run/php/php7.1-fpm.sock|fcgi://localhost"
        SetHandler "proxy:fcgi://127.0.0.1:9000"
    </FilesMatch>

# apache2ctl configtest
# systemctl restart apache2 && systemctl status apache2

Install and enable the following Apache modules if you are connecting to PHP through a TCP socket (127.0.0.1:9000):

# apt-get install libapache2-mod-fastcgi
# a2enmod fastcgi rewrite setenvif


Edit apache2.conf:

# vim /etc/apache2/apache2.conf

AllowOverride All

Set up a virtual host:

# cd /etc/apache2/sites-available
# cp 000-default.conf mag2.local.conf
# vim mag2.local

Check the configuration:

# apache2ctl -V
# apache2ctl -t
# apache2ctl -M
# apache2ctl configtest

Enable the site:

# a2ensite mag2.local

Start MySQL, PHP, and Apache:

# systemctl restart mysql.service
# systemctl restart php7.0-fpm.service
# systemctl restart apache2.service

# ps auxww | grep -i mysql
# ps auxww | grep -i php-fpm
# ps auxww | grep -i apache2

Install PHPStorm:

# cd ~jun/Downloads/
# tar xf PhpStorm-*.tar.gz -C /opt/
# cd /opt/PhpStorm-163.10504.2/
# ./bin/phpstorm.sh

Generate a self-signed SSL certificate:

# openssl req -x509 -nodes -days 365 -newkey rsa:2048 -subj "/C=CA/ST=British Columbia/L=Vancouver/O=My Company Name/CN=erp.local" -keyout /etc/ssl/private/test.local.key -out /etc/ssl/certs/test.local.crt
