Mysql Crash Recovery
1) Verify the current process and status
========================================
ps auxf | grep mysql By this command we can find any mysql process in the server.
ps -aux | grep mysql
The -a option tells ps to list the processes of all users on the system rather than just those of the current user, with the exception of group leaders and processes not associated with a terminal. A group leader is the first member of a group of related processes.
The -u option tells ps to provide detailed information about each process.
The -x option adds to the list processes that have no controlling terminal, such as daemons, which are programs that are launched during booting (i.e., computer startup) and run unobtrusively in the background until they are activated by a particular event or condition.
The output of the command is
>ps -aux | grep mysql
root@cpmouse [/var/lib/mysql]# ps auxf | grep mysql
root 16673 0.0 0.0 61128 712 pts/1 S+ 18:30 0:00 \_ grep mysql
root 11142 0.0 0.0 10796 1160 ? S 06:24 0:00 /bin/sh /usr/bin/mysqld_safe --datadir=/var/lib/mysql --pid-file=/var/lib/mysql/cpmouse.ecdsystem.com.pid

To check the mysql current processes
ps -ef |grep mysql|awk '{print $2}'
This command will grep the second column only.
2)Verify /etc/my.cnf settings
[mysqld]
safe-show-database
old-passwords = 1
skip-name-resolve
skip-locking
set-variable = max_connections=2000
set-variable = interactive_time=30
set-variable = wait_timeout=30
set-variable = max_connect_errors=2000
3)Have a look out the mysqld Permission settings
=================================================
The Permission should be in mysql format
chown mysql.mysql /var/run/mysqld
We have to change the ownership for all the mysql processes.
chown -R mysql.mysql /var/run/mysqld
root@cpmouse [/var/lib/mysql]# ll
total 20556
drwxr-xr-x 4 mysql mysql 4096 May 30 04:29 ./

Ps Process command Usage with options
The ps Command
The ps (i.e., process status) command is used to provide information about the currently running processes, including their process identification numbers (PIDs).
A process, also referred to as a task, is an executing (i.e., running) instance of a program. Every process is assigned a unique PID by the system.
The basic syntax of ps is
ps [options]
The four items are labeled PID, TTY, TIME and CMD. TIME is the amount of CPU (central processing unit) time in minutes and seconds that the process has been running. CMD is the name of the command that launched the process.
TTY (which now stands for terminal type but originally stood for teletype) is the name of the console or terminal (i.e., combination of monitor and keyboard) that the user logged into, which can also be found by using the tty command. This information is generally only useful on a multi-user network.
A common and convenient way of using ps to obtain much more complete information about the processes currently on the system is to use the following:
ps -aux | less
The -a option tells ps to list the processes of all users on the system rather than just those of the current user, with the exception of group leaders and processes not associated with a terminal. A group leader is the first member of a group of related processes.
The -u option tells ps to provide detailed information about each process.
The -x option adds to the list processes that have no controlling terminal, such as daemons, which are programs that are launched during booting (i.e., computer startup) and run unobtrusively in the background until they are activated by a particular event or condition.
As the list of processes can be quite long and occupy more than a single screen, the output of ps -aux can be piped (i.e., transferred) to the less command, which lets it be viewed one screenful at a time. The output can be advanced one screen forward by pressing the SPACE bar and one screen backward by pressing the b key.
Among the information that ps -aux provides about each process is the user of the process, the PID, the percentage of CPU used by the process, the percentage of memory used by the process, VSZ (virtual size in kilobytes), RSS (real memory size or resident set size in 1024 byte units), STAT (the process state code), the starting time of the process, the length of time the process has been active and the command that initiated the process. The process state codes include D, uninterruptable sleep; N, low priority; R, runnable (on run queue); S, sleeping; T, traced or stopped; Z, defunct (zombie).
In contrast to most commands, the hyphen preceding ps's options is optional, not mandatory. Thus, the following could be (and sometimes is) used in place of the above command:
ps aux | less
An alternative set of options for viewing all the processes running on a system is
ps -ef | less
The -e option generates a list of information about every process currently running. The -f option generates a listing that contains fewer items of information for each process than the -l option.
Among the columns displayed by ps -ef, UID contains the username of the account that owns the process (which is usually the same user that started the process) and STIME displays the time the process started, or the starting date if it started more than 24 hours ago.
The processes shown by ps can be limited to those belonging to any given user by piping the output through grep, a filter that is used for searching text. For example, processes belonging to a user with a username adam can be displayed with the following:
ps -ef | grep adam
The -l option generates a long listing, and when used together with the -e and -f options creates a table with 15 columns:
ps -efl
The additional columns of most interest are NI and SZ. The former shows the nice value of the process, which determines the priority of the process. The higher the value, the lower the priority. The default nice value is 0 on Linux systems.
The latter displays the size of the process in memory. The value of the field is the number of pages the process is occupying. On Linux systems a page is 4,096 bytes.
ps is most often used to obtain the PID of a malfunctioning process in order to terminate it with the kill command. For example, if the PID of a frozen or crashed program is found to be 1125, the following can usually terminate the process:
kill 1125
ps -ef or ps -efl can then be used to confirm that the process really has stopped. If it has not, then the more forceful -9 option should be used, i.e.,
kill -9 1125
The pstree command is similar to ps in that it can be used to show all of the processes on the system along with their PIDs. However, it differs in that it presents its output in a tree diagram that shows how processes are related to each other and in that it provides less detailed information about each process than does ps.

MYSQL Password Reset
Checking My sql version
=======================
mysql -V
mysql Ver 14.12 Distrib 5.0.86, for pc-linux-gnu (i686) using readline 5.1
Reset Mysql Password for mysql Ver 14.12
=========================================
mysql>set password for 'teachersdb_Ads'@'localhost' = password('98m4@9er');
For some other versions
=======================
UPDATE user SET Password=PASSWORD('1q2w3e4r') WHERE User=’teachersdb_Ads’;
For mysql login:
================
mysql -u username -p password
To set All privileges to My sql DB
===================================
GRANT ALL PRIVILEGES ON teachersdb_Ads.* TO teachersdb_Ads @'174.37.6.90' IDENTIFIED BY '4645bvg6dgdr'
You will start by logging into your server via ssh and logging into your MySQL entering the following:
mysql –uadmin –p`cat /etc/psa/.psa.shadow`
Grant Privilege
GRANT SELECT ON database.* TO username@'localhost' IDENTIFIED BY 'password';
To enable more options you would separate them with a comma. So to enable SELECT, INSERT, and DELETE your syntax would look like this;
GRANT SELECT, INSERT, DELETE ON database.* TO username@'localhost' IDENTIFIED BY 'password';
Once you have given the desired privileges for your user, you will need to run this command within the MySQL command prompt;
FLUSH PRIVILEGES;
To see a list of the privileges that have been granted to a specific user;
select * from mysql.user where User='user' \G

Use of .htaccess file
Using with .htaccess we can do following:
How to deny IP specific addresses?
# vi /home/user/public_html/.htaccess
Order allow, deny
Deny from 192.168.0.10
Deny from 212.155.
Deny from 1.2.3.4 5.6.7.8 127.0.0.1
Allow from all
How to prevent or allow directory listing?
The following line enables Directory listing.
Options +Indexes
The following disables directory listing for your web site.
Options –Indexes
With .htaccess file you can control which files to be ignored when creating a directory list.
For example:
IndexIgnore *.gif *.zip *.txt
Will make the apache server to skip all gif, zip and txt files from the directory list.
IndexIngnore *
Will just create an empty directory list.
You can use custom error pages for any error as long as you know its number (like 404 for page not found) by adding the following to your .htaccess file:
ErrorDocument errornumber /file.html
For example if I had the file notfound.html in the root direct
ory of my site and I wanted to use it for a 404 error I would use:
ErrorDocument 404 /notfound.html
Protecting a folder:
cd /home/user/public_html/
htpasswd -c .htpasswd username
the above command will create .htpasswdfile
To password protect a folder on your site, you need to put the following code in your .htaccess file:
AuthUserFile /full/path/to/.htpasswd
AuthType Basic
AuthName "My Secret Folder"
Require valid-user
Hotlink Protectection:
You can prevent the hot-linking of your images by creating a .htaccess file with the following content:
RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www.)?your-domain.com/.*$ [NC]
RewriteRule \.(gif|jpe?g|png)$ - [F]
To block other type of files, just add their extension to the list above. For example to block movie files:
RewriteRule \.(mov|avi|wmv|mpe?g)$ - [F]
The Hot-Linking prevention is based on an Apache module called ModRewrite.
Redirection:
The Apache web server provides several way for setting up redirects.
The most simple one is using the “Redirect” directive:
Redirect /folder
http://www.example.com/newfolder
With such a line in your .htaccess if a visitor tries to load
http://www.example.com/folder
he will be redirected to
http://www.example.com/newfolder
You can add a status code to the Redirect directive. For example for Permanent 301 redirect you can use:
Redirect permanent /folder
http://www.example.com/newfolder
Another useful directive is the RedirectMatch. With it you can use regular expressions in the redirect condition. For example
RedirectMatch "\.html$"
http://www.example.com/index.php
This will redirect all requests to files that end with .html to the index.php file.
Introduction to mod_rewrite and some basic examples:
Create easy to remember URLs or also known as COOL URIs, other call them Search Engine Friendly URLs. For example you have some complicated site driven by some server-side scripting language: PHP, Perl, etc. In general its URLs will look like
http://www.example.com/view.php?cat=art ... 20&lang=en
It is not easy to remember such URL.
Using ModRewrite you can make the URL look like:
http://www.example.com/en/articles/10-2
Here is the code:
RewriteEngine On
RewriteRule ^([a-z]*)/([a-z]*)/([1-9]+)(-[1-9]+)? $

Invalid maildirsize file Error in cpanel
Solution :
If you see the error "Invalid maildirsize file" when trying to update your email account password, or change the quota, or if you are just having issues with logging in you should try this:
Log into cPanel, click on File Manager, click on the folder icon next to the mail folder, click on the folder icon next to the domain name, click on the folder icon next to the email user name, then click on the file called maildirsize in that folder (don't click on the icon but the file's name itself). In the upper right hand list of links, click to delete the file. Once you delete it, it will reform for the account automatically and it should then have the correct quota size.
