MYSQL issue in slackware 13.0

simeon.mattes · 10-03-2009, 07:56 AM

Hi,

I have installed slackware 13.0 in my pc and I use the the build-in mysql server that slackware has. Every time my computer starts I receive the following error:

Code:

Starting mysqld daemon with databases from /var/laib/mysql
STOPPING server from pid file /var/run/mysql/mysql.pid

Every time I try to restart mysql server with the following command:

Code:

/etc/rc.d/rc.mysqld restart

I get the error:

Code:

root@slackfractals:/home/simeon# nohup: redirecting stderr to stdout
Starting mysqld daemon with databases from /var/lib/mysql
STOPPING server from pid file /var/run/mysql/mysql.pid
091003 15:49:23  mysqld ended

Every time I try to run mysql command I get the error message:

Code:

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

I was looking around in the Internet to find a solution, but without any success. The only things I found out are:

There is no mysql.sock file in my whole computer

and my /var/lib/mysql/slackfractals.err file has the following errors:

Code:

Any suggestions?

Hi,

Did you initially install the database (mysql_install_db command) and set a password (mysqladmin command) for the mysql root user? Also check to see if there is a /etc/my.cnf file present.

I do believe the rc.mysql file has this info inside it.

Hope this helps.

hi druuna,

thanks for your response. Actually I didn't install anything. I just installed the packages for mysql, which are offered from slackware.

Nevertheless, I run mysql_install_db and I get the following:

Code:

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h slackfractals password 'new-password'

Alternatively you can run:
/usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/bin/mysqlbug script!

The latest information about MySQL is available on the web at
http://www.mysql.com
Support MySQL by buying support/licenses at http://shop.mysql.com

Then, I run mysql_secure_installation and I get:

Code:

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL

In order to log into MySQL to secure it, we'll need the current
password for the root user.  If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):

I tried to find the my.cnf file without any success, but I found my-huge.cnf, my-large.cnf, my-medium.cnf and my-small.cnf. I copied my-large.cnf as my.cnf which contains:

# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:                                                    
#

#                                                                      
#    where you replace <host>, <user>, <password> by quoted strings and
#    <port> 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)

Hi,

I do believe that the mysql db must be running before you execute the mysql_secure_installation part (never used it myself. I use the /usr/bin/mysqladmin -u root password 'new-password' part, and the db must be up and running for that one).

Start the db with the following statement: mysqld_safe --user=mysql 2>&1 >/dev/null & and try the mysql_secure_installation step again. I'm fairly sure this time it will work.

BTW: Do you really need the large.cnf? Most of the time (home usage) medium or small will do fine.

In short these are the basic steps to take after installing mysql:

1) Install database: mysql_install_db --user=mysql,
2) Start mysql: mysqld_safe --user=mysql 2>&1 >/dev/null &,
3) Set root password: mysqladmin -u root password 'new-password' (or use the mysql_secure_installation command),
4) Stop mysql: mysqladmin -p shutdown (passwd will be asked).
Done.

Hope this helps.

so you should just press enter here.

Enter current password for root (enter for none):
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run                                       /mysql/mysql.sock' (2)
Enter current password for root (enter for none):

With the other steps you gave me I had the following result:
1) Install database: mysql_install_db --user=mysql,

Examine the logs in /var/lib/mysql for more information.
You can try to start the mysqld daemon with:
/usr/libexec/mysqld --skip-grant &
and use the command line tool
/usr/bin/mysql to connect to the mysql
database and look at the grant tables:

shell> /usr/bin/mysql -u root mysql
mysql> show tables

Try 'mysqld --help' if you have problems with paths. Using --log
gives you a log in /var/lib/mysql that may be helpful.

Check that /var/lib/mysql and all files in it be owned by user mysql:mysql. If not, chown -R mysql:mysql /var/lib/mysql.

druuna · 10-04-2009, 01:15 PM

I have to agree with Didier Spaier.

You (simeon.mattes) have been trying out some different solutions (I do believe with and without the --user=mysql option), which probably messed up the permissions on (some of) the mysql files.

This being a fresh install you could always decide to uninstall mysql and reinstall it fresh and apply the 4 steps I mentioned in post #4.

simeon.mattes · 10-04-2009, 02:50 PM

I think I managed to configure it. It seems that it works. Actually I reinstalled mysql through slackpkg after I had removed /var/lib/mysql and I run the steps you have told me.

Though I can't run a .php file in my domain. I get the content of my php file instead. I'll look it out again and if I don't manage to configure it I 'll ask.

Thanks.

Hi,

This:

has nothing to do with mysql.

Php and apache work closely together, I do believe you need to uncomment a line in your httpd.conf file to "activate" php.
Look for these:

Quote:

AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps

You do need to restart apache after editing the httpd.conf file.

Hope this helps.

simeon.mattes · 10-04-2009, 03:16 PM

Yes, I know it...I had already done it.

Thanks again

Didier Spaier · 10-04-2009, 03:27 PM

Thats not all.

If not yet done, you also have to uncomment (remove the leading '#') following line near the end of httpd.conf:

Code:

#Include /etc/httpd/mod_php.conf

and replace:

Code:

<IfModule dir_module>
    DirectoryIndex index.html
</IfModule>

by:

Code:

<IfModule dir_module>
    DirectoryIndex index.html index.php
</IfModule>

Druuna,
I have run into the same problems that this old thread deals with and your suggestions do not work. Going through the following steps, as you suggest, fail:

1) Install database: mysql_install_db --user=mysql,
2) Start mysql: mysqld_safe --user=mysql 2>&1 >/dev/null &,
3) Set root password: mysqladmin -u root password 'new-password' (or use the mysql_secure_installation command),
4) Stop mysql: mysqladmin -p shutdown (passwd will be asked).

Steps 1 & 2 work, it seems. Step 3 bombs with this:
error: 'Can't connect to local MySQL server through socket '/var/run/mysql/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/var/run/mysql/mysql.sock' exists!

Using mysql_secure_installation it croaks when it asks for the root password. Whether I leave it blank or enter the old password, I get this:
Enter current password for root (enter for none):
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysql/mysql.sock' (2)
Enter current password for root (enter for none):
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysql/mysql.sock' (2)
Enter current password for root (enter for none):
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysql/mysql.sock' (2)
Enter current password for root (enter for none):

This message from the program is correct: there is no mysql.sock anywhere in the system. I did a fresh install of mysql and it is not being created. I have searched the mysql.org site and there is no help that I could find.

The strange thing is that this is an all of a sudden thing. Mysql was working fine, then for no reason that I can determine these problems started.

Another thing, it was recommended to run mysql-test-run.pl. Well, I would like to but where is this program available? There is a man page on it but not even the mysql.org site indicates where it can be downloaded. Googling does not help either.

Do you have any suggestions?

My OS is Slackware 13.1 64bit.

Absolutely great! I feel LAMP empowered! What else can you do?
