 Posted: Sun Mar 16, 2003 12:33 pm Post subject: mysql unable to run after emerge due to socket error?? |
 |
|
I recently emerged mysql and have not been able to run it yet.
When I do a "mysql" from a root user command prompt I get...
| Code: |
pine [/etc]
# mysql
ERROR 2002: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
pine [/etc]
|
For some time I have seen a warning (or error?) being reported on bootup. I am wondering if it has something to do with my inability to run mysql? The message at bootup says...
| Code: |
NET4: Unix domain sockets 1.0/SMP for Linux NET4.0.
ds: no socket drivers loaded!
|
Am I missing something in my kernel? How do I get around this socket error condition?
Any insight would be appreciated.
Thanks.
Carlos

Have you tried to connect via TCP/IP maybe with mysqlcc ???
If even this fails, have you started mysqld??? (etc/init.d/mysqld start)?? (I know this might be a stupid help, as you're already apprentice, but maybe...)
is mysqld reporting any errors??? |

Thanks very much Starfox. Your suggestions helped me figure out how to start it!! Even if I am an apprentice 
Actually I am really still a newbie who has been asking a lot of questions which has resulted in being labeled an apprentice. Next thing you know I'll be labeled a guru.
Here's what I did to get it working for those having a similar problem...
| Code: |
carlos@pine [~]
$ mysqlcc
bash: mysqlcc: command not found
carlos@pine [~]
$ mysqld
bash: mysqld: command not found
carlos@pine [~]
$ su -
Password:
pine [~]
# find / -name mysqlcc
/usr/portage/dev-db/mysqlcc
pine [~]
# find / -name mysqld
/var/run/mysqld
/usr/sbin/mysqld
pine [~]
# /usr/sbin/mysqld
030316 6:32:48 /usr/sbin/mysqld: Table 'mysql.host' doesn't exist
pine [~]
# /etc/init.d/mysql status
* status: stopped
pine [~]
# /etc/init.d/mysql start
* You dont appear to have the mysql database installed yet.
* Please run /usr/bin/mysql_install_db to have this done...
pine [~]
# /usr/bin/mysql_install_db
Preparing db table
Preparing host table
Preparing user table
Preparing func table
Preparing tables_priv table
Preparing columns_priv table
Installing all prepared tables
030316 6:33:57 /usr/sbin/mysqld: Shutdown Complete
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
This is done with:
/etc/init.d/mysql start (you have to start the server first!)
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h pine password 'new-password'
See the manual for more instructions.
Please report any problems with the /usr/bin/mysqlbug script!

pine [~]
# /etc/init.d/mysql start
* Starting mysqld... [ ok ]
pine [~]
# mysql
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1 to server version: 3.23.54-log
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql> exit
Bye

I was right with you until the end. | Code: |
Martha mysql # /etc/init.d/mysql start
* WARNING: "mysql" has already been started.
Martha mysql # mysql
ERROR 2002: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
|
(Which is where I started from).
It thinks that mysqld has been started, yet no socket is there.
Anyone have a clue?
Thanks |

Hi,
what's in /etc/my.cnf ? Have you already looked up open ports and sockets with netstat -na ? If not plz look it up and post if you don't know what it mean... =) |

If mysqld is not running, try | Code: | | /etc/init.d/mysqld zap |
. Then you can try to start again. Also look at your mysql logfiles, which can be found in /var/log/mysql (if you are using metalog).

I had this problem about not being able to connect.
mysql is a client.
mysqld is a daemon which you need to first run.
To load the mysqld, u need a script to do that, and it's called safe_mysqld
ace root # which safe_mysqld
/usr/bin/safe_mysqld
after that, u need to connect to the mysqld by:
mysql -p -u root
use -p if there's a password assigned; u'll be prompted a password.
if a password was assigned and u forgot it, that's a harder thing to solve..i suggest you read the mysql manual from the mysql site.
