Ansible

Ansible

              Ansible is the simplest way to deploy your applications. Ansible gives you the power to deploy multi-tier applications reliably and consistently, all from one common framework. You can configure needed services as well as push application artifacts from one common system.

Rather than writing custom code to automate your systems, your team writes simple task descriptions that even the newest team member can understand on first read -- saving not only up-front costs, but making it easier to react to change over time.

Reset Password MySQL User

Reset Password MySQL User

Sometime we also forgot or miss mysql user password. and here are the way to reset password mysql user. But we need to have mysql root `s password.

If you are also forgot or miss mysql root`s password. 

Here is my previous article:  Recovery MySQL Root Password

HowTo -  Reset password mysql user.

1. Log in as root 

(In this example database server is "localhost", If  mysql server on different server we need to specify with -h option for database host.)

mysql -u root -p
2. Use mysql database and update new password for user "vannak"
use mysql;
UPDATE mysql.user SET Password=PASSWORD('NewPassw0rd') WHERE User='vannak' AND Host='localhost';
FLUSH PRIVILEGES;

Install Multiple MySQL Versions On a Single Server

Install Multiple MySQL Versions On a Single Server

We usually need to use different version of a software in a single server in some case for testing, And some are because of requirements of some apps...,

In this example is going to install multiple MySQL version on a single server.

OS: Ubuntu Server 12.04
Default MySQL versoion: 5.5.34
Compiled MySQL version: 5.1.65
Note:
- mysql-server IP: 192.168.5.5
- remote-client IP: 192.168.5.1

1. Install MySQL from APT-GET
2. Install MySQL from Compile
    2.1. Required Softwares
    2.2 Compile MySQL
          2.2.1 Download
          2.2.2 Extract
          2.2.3 Compile

1. Install MySQL from APT-GET
#apt-get install mysql-server
During the installation will be ask you to enter root's password.

Log in into MySQL server by command:
# mysql -u root -p

Create a test database after login by command:
#mysql> create database dbtest1;

2. Install MySQL from Compile

2.1. Required Softwares
Install compiler tools

#apt-get install build-essential libncurses-dev libstdc++6 libc6 libltdl-dev autoconf

2.2 Compile MySQL 
Create folder structure,
In this example we are going to install another MySQL version 5.1.65 in /opt/mysql-versions/
# mkdir -p /opt/mysql-versions/mysql5165/datafiles
# mkdir -p /opt/mysql-versions/mysql5165/logs
# mkdir -p /opt/mysql-versions/mysql5165/pid
# mkdir -p /opt/mysql-versions/mysql5165/socket
2.2.1 Download 
wget http://downloads.mysql.com/archives/mysql-5.1/mysql-5.1.65.tar.gz

2.2.2 Extract
tar -xvf mysql-5.1.65.tar.gz
2.2.3 Compile
Go to folder mysql-5.1.65:
# cd mysql-5.1.65
-------------------------------------------------------------------------------------------------------------------------
./configure --prefix=/opt/mysql-versions/mysql5165/ --enable-assembler --with-mysqld-ldflags=-all-static --with-tcp-port=3307 --with-unix-socket-path=/opt/mysql-versions/mysql5165/socket/mysql5165.sock
-------------------------------------------------------------------------------------------------------------------------

Run command: make and make install
# make
# make install

After run command "make install"
create a file name "mysql5165.cnf" with content:
-------------------------------------------------------------------------------------------------------------------------
# Example MySQL config file for medium systems.
#
# This is for a system with little memory (32M - 64M) where MySQL plays
# an important part, or systems up to 128M where MySQL is used together with
# other programs (such as a web server)
#
# MySQL programs look for option files in a set of
# locations which depend on the deployment platform.
# You can copy this option file to one of those
# locations. For information about these locations, see:
# http://dev.mysql.com/doc/mysql/en/option-files.html
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:
#
#    CHANGE MASTER TO MASTER_HOST=, MASTER_PORT=,
#    MASTER_USER=, MASTER_PASSWORD= ;
#
#    where you replace , , by quoted strings and
#     by the master's port number (3306 by default).
#
#    Example:
#
#    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
#    MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
#    start replication for the first time (even unsuccessfully, for example
#    if you mistyped the password in master-password and the slave fails to
#    connect), the slave will create a master.info file, and any later
#    change in this file to the variables' values below will be ignored and
#    overridden by the content of the master.info file, unless you shutdown
#    the slave server, delete master.info and restart the slaver server.
#    For that reason, you may want to leave the lines below untouched
#    (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id       = 2
#
# The replication master for this slave - required
#master-host     =  
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user     =  
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password =  
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port     =

Script Change PHP Versions

Script Change PHP Versions

I am lazy to edit the vhost file to change the PHP version that I usually change,
So I create this script to help me complete this task. :D

This is the script to change PHP version which is base on where you keep the path of your PHP.
Download this script file and put somewhere on you computer.

*** Adjust this script base on your custom configurations.

How to run the script:
sudo ./change-php-version.sh
You will get the options to choose:

Please select the options, Enter the number only.
1. For list virtualhost
2. For list PHP version
3. For Change PHP version
4. For Exit

Note: If you choose option number 3 you need to provide other informations in order to change PHP version such as:
* virtualhost-name
* PHP version

As the following example:

Please Enter virtualhost file:
(example: local.demo)
local.demo

Please Enter PHP version number only:
(example: 5.3.8)
 5.4.9
If the virtualhost file exist and with PHP version is correct, Script will run without error.

Changing PHP Version to 5.4.9
 * Reloading web server config                                                              [ OK ]
Virtualhost local.demo changed to PHP version 5.4.9

Done, In this example, The script will change vhost file local.demo to PHP version 5.4.9.
