   1. 1.Create YUM locally and than execute yum install mysql* it won’t need any internet connection. And will solve all dependency.
      If will go for Manuall RPM installation than it would be a hectic task to solve dependency.

   2. Hi Mony,

      you can disable the gpgchek in /etc/yum.repos.d/yourrepo.
      after that you run again command
      yum repolist. or you can read my blog in section create local repository.
      Maybe it could help you.
      Thanks.

    ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’ (2)

12. When you don’t remember root password and enter a wrong password, you will get the following MySQL error message.
    # mysql -u root mysql
    ERROR 1045 (28000): Access denied for user ‘root’@’localhost’ (using password: NO)
    1. Stop MySQL Server
    As a first step, stop the mysql server using one of the following method.
    # service mysql stop

    (or)

    # /etc/rc.d/init.d/mysql stop
    2. Add –skip-grant-tables to mysqld_safe Startup Command
    Open the mysql startup script and add -skip-grant-tables as shown below.
    # vi /etc/rc.d/init.d/mysql

    Old Line: $bindir/mysqld_safe –datadir=$datadir –pid-file=$server_pid_file $other_args >/dev/null 2>&1 &

    New Line: $bindir/mysqld_safe –skip-grant-tables –datadir=$datadir –pid-file=$server_pid_file $other_args >/dev/null 2>&1 &
    3. Start MySQL Server With –skip-grant-tables
    Start the mysql server with skip-grant-tables option, which will allow anybody to login to mysql without entering a password.
    # service mysql start
    Starting MySQL. [ OK ]
    [Note: This is using the updated /etc/rc.d/init.d/mysql script]
    4. Login Using MySQL Root User Without Entering Password
    Since you’ve skipped the grant table, this time when you try to login to mysql, it will not ask for password.
    # mysql -u root mysql
    Reading table information for completion of table and column names
    You can turn off this feature to get a quicker startup with -A

    Welcome to the MySQL monitor. Commands end with ; or \g.

    [Note: MySQL did not ask for any password]

13. Fix: Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’

    ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’

    if you are new to installing mysql server you might probably face this error quite often if you type mysql in the shell prompt.

    > mysql
    ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’

    To fix:

    First start the mysql daemon, then type mysql

    > /etc/init.d/mysqld start
    > mysql

    Bingo! It worked for me!

    To update mysql root password

    mysql> USE mysql;
    mysql> UPDATE user SET Password=PASSWORD(‘new-password’) WHERE user=’root’;
    mysql> FLUSH PRIVILEGES;

    To add a new user to mysql

    1. First login as root then create a database ‘demo’

    > mysql -u root -p
    Enter password:
    mysql> create database demo;

    After that create a new user named ‘guest’ with password ‘guest’ with all previleges assigned to demo database;

    mysql> GRANT ALL PRIVILEGES ON mytest.* TO ‘guest’@’localhost’ IDENTIFIED BY ‘guest’ WITH GRANT OPTION;

    Then exit mysql and connect through username guest;
    That should work!

14. i try to use yum install and it gives this message that says “Existing lock /var/run/yum.pid: another copy is running as pid 3406.
    Another app is currently holding the yum lock; waiting for it to exit…”
    what can i do to make thing right.
    if any help please help me.

    1. open the file with vi /var/run/yum.pid and then remove pid 3406 which is inside that.

15. I used yum install mysql-server mysql and it installed great. Then I tried to start the server with this: /etc/init.d/mysqld start andd it said mysqld doesn’t exist. I should mention that I’m installing this on a work machine, running REHL5 and I don’t have root permissions. I do have sudo rights. I asked whereis MySQL and it returned 4 locations. How do I start the server or configure it so I can start it? Thanks for your help.

    1. Use sudo to start mysql.

16. I’ve actually tried every sudo start mysql command that I’ve found and not been successful. Its funny because it was no problem from my windows install but this red hat enterprise install isn’t making sense.

17. Correct syntax to start / stop / restart with sudo:
    sudo /etc/init.d/mysqld start
sudo /etc/init.d/mysqld status
sudo /etc/init.d/mysqld restart
sudo /etc/init.d/mysqld stop
    OR
    sudo /sbin/service mysqld start
    What is the output of the following command?
    netstat -tulnp | grep mysql

18. I did sudo netstat -tulnp | grep mysql and it went back to the prompt after requesting password. Without sudo, it said “(No info could be read for “-p”: getuid()=45717 but you should be root.)

    sudo /sbin/service mysqld start
    returned: mysqld: unrecongnized service

    sudo /etc/init.d/mysqld start
    returned: sudo: /etc/init.d/mysqld: command not found
    sudo /etc/init.d/mysqld status
    returned: sudo: /etc/init.d/mysqld: command not found
    sudo /etc/init.d/mysqld restart
    returned: sudo: /etc/init.d/mysqld: command not found
    sudo /etc/init.d/mysqld stop
    returned: sudo: /etc/init.d/mysqld: command not found

    This is my first foray into RHEL, I’ve used Ubuntu previously (about 2 years ago), and recently been running mysql/apache with XAMPP sucessfully, and that’s not a production platform (as you know). But I have a project that I would like to run on a Linux box (production), for obvious reasons (well, obvious to me). I appreciate your help with this.

19. So, update – I found that I needed to install something else: mysql-devel. Now that that is there, I ran sudo /usr/bin/mysqld_safe & and that was successful. However, when I run sudo /etc/init.d/mysqld status it returns this:

    mysqld dead but subsys locked

    any suggestions?

    Thanks!

    1. /usr/bin/mysqld_safe &

       Another way to start mysql server. I suggest you reboot your box and type the same command again. It should clean up lock files. It is possible to get rid of problem online but you need to go thorugh kill, rm and other commands.
