MySQL not getting started on linux

Question

my.cnf missing on all directories after new mysql installtion

I need to run MySQL service for my linux 2.16 version with SUSE version 11 distribution. Downloaded the following files and installed all the rpms as under:

MySQL-server-5.5.27-1.sles11.i586
MySQL-client-5.5.27-1.sles11.i586
MySQL-devel-5.5.27-1.sles11.i586
MySQL-shared-5.5.27-1.sles11.i586
MySQL-shared-compat-5.5.27-1.sles11.i586

There was no error during installation and I have confirmed the installed packages via:

rpm -qa|grep -i sql

But the server is not getting started when trying to execute through:

$> mysql

M getting the following as eror msg:

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

I have checked that in the /etc/init.d location, only mysql entry is there instead of mysqld, is this the reason of the server startup error.

On googling for hours, I have also tried ./mysql start from the same location but getting the following output:

Starting MySQL..The server quit without updating PID file (/var/lib/mysql/ABC2-rahul.pid).

I am new to mysql, any help will be appreciated. Thanks in advance.

I have cheked and found that some configuration files have been in the /usr/share/mysql loaction, and I have copied my-huge.cnf file to /etc location, any comments ?

Following is the content from the same my.cnf file:

[mysqld]
port            = 3306
socket          = /var/lib/mysql/mysql.sock
skip-external-locking
key_buffer_size = 384M
max_allowed_packet = 1M
table_open_cache = 512
sort_buffer_size = 2M
read_buffer_size = 2M
read_rnd_buffer_size = 8M
myisam_sort_buffer_size = 64M
thread_cache_size = 8
query_cache_size = 32M

thread_concurrency = 8

log-bin=mysql-bin

server-id       = 1

[mysqldump]
quick
max_allowed_packet = 16M

[mysql]
no-auto-rehash

[myisamchk]
key_buffer_size = 256M
sort_buffer_size = 256M
read_buffer = 2M
write_buffer = 2M

[mysqlhotcopy]
interactive-timeout

Just try `/etc/init.d/mysql start` and check the log files, usually in `/var/log/mysql`. — golja, Sep 26 '12 at 11:10
Thanks but on trying to start mysql, even m wondering why but there is not any log file for mysql in the location /etc/init.d !! — Manroop, Sep 26 '12 at 11:14
ya i have posted dat wrong in my above cmment, i have cheked but there isnt any log file created for mysql in d location /var/log !! — Manroop, Sep 26 '12 at 11:38
I think that you made a wrong installation. In the rpm's there are usually all the files. Try: rpm -q MySQL-server-5.5.27-1 --filesbypkg | grep my.cnf — AndrewQ, Sep 26 '12 at 13:06
@AndrewQ no output, tried dat also. But on checking with rpm -qa | grep -i sql it shows the installed mysql packages and also i have downloaded from mysql official download page, also installed successfully, but still error. — Manroop, Sep 27 '12 at 04:57

Looks a lot like permission issues check that /var/lib/mysql is owned by the same user as the one running the mysql daemon.

It seems that your package is malformed or incomplete.

To solve this, create your own my.cnf file.

Verify that a 'mysql' user has been created. If not, create auser mysql and a group mysql.

In /etc create my.cnf with a minimal set of settings:

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
port=3306

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

[client]
user=root
port=3306
socket=/var/lib/mysql/mysql.sock

This should be enough to keep mysqld up and running. of course, you have to add your settings. Start the server using /etc/init.d/mysql start (or the command that your distro uses to start a service).

If the server starts, you have to create the root user (usually with 'mysqladmin -u root -p password' and 'mysqladmin -h hostname -u root -p password')
