MySQL is not starting after Shutdown

[Renjith T]

Hi,

I am new to mysql. For a requirement, I had to stop mysql by the following command.

mysqladmin -u <user> -p <pwd> shutdown

After that I am unable to start the server. I've used the following option.

1. ./mysqld
Result:
160118 3:28:57 [Warning] option 'thread_stack': unsigned value 126976 adjusted to 131072
160118 3:28:57 [ERROR] Can't find messagefile '/usr/local/mysql/share/mysql/english/errmsg.sys'
160118 3:28:57 [ERROR] Aborting

2. ./mysql -u <usr> -p <pwd> localhost
./mysql -u <usr> -p <pwd> 127.0.0.1

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

3. ./mysqladmin -u <usr> -p <pwd> start
Result:
./mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/tmp/mysql.sock' exists!

Thanks in advance.
