A,: 1130-host ... is not allowed to connect to this MySql server how to deal with
First encountered this problem on the server where treated with mysql connection
1, the connection server: mysql -u root -p
2, look at all the current databases: show databases;
3, enter the mysql database: use mysql;
4, to see all the tables in the mysql database: show tables;
Of which: with grant option is to have permission to cascade to other authorized users
all privileges on *. * permissions
ps -A | grep -i mysql
kill processes listed
service mysql start
My problem is solved

Fedora8 start mysql error:
ERROR 2002 (HY000): of Can not Connect to local MySQL Server through socket '/var/lib/mysql/mysql.sock' (2)
1, first check /etc/rc.d/init.d / mysqld status to see if mysql has been launched.
Also see if it is a permissions problem.
2. determine your mysql.sock are not in that position,
mysql mysql -u your username -p -S / var / lib / mysql /mysql.sock
. 3, try: Start-Service mysqld
. 4, if authority, permission to change the first MySQL -R & lt #chown: MySQL / var / lib / MySQL
[the root @ localhost ~] # /etc/init.d/ mysqld start
start MySQL: [OK]
[root @ localhost ~] # MySQL-uroot--p
ERROR 2002 (HY000): of Can not Connect to local MySQL Server through socket '/var/lib/mysql/mysql.sock' (2 )
the reason is that access issues / var / lib / mysql's.
shell> chown -R mysql: mysql / var / lib / mysql
then start the server
shell> /etc/init.d/mysql start
the server starts the normal viewing / var / lib / mysql mysql.sock automatically generated file.
But my question remains unresolved.
Finally solved the problem:
Method: Review /etc/my.conf:
[mysqld]
DATADIR = / usr / local / MySQL / Data
Socket = / var / lib / MySQL / mysql.sock
[the mysql.server]
User = MySQL
the basedir = / usr / local / MySQL
the If there IS Not Currently A sectionTop Called [Client], the Add One AT The bottom of The File and Copy The Socket = Line an under The [mysqld] sectionTop SUCH AS:
[Client]
Socket = / var / lib / mysql / mysql.sock
found that still the case, being given the run /etc/init.d/mysql start: Starting MySQLCouldn't find MySQL manager or server
is the mysqld service did not start, run / usr / local / mysql / bin / mysqld_safe &
My solution is to re-profile [client] module adds
the socket = / var / lib / mysql / mysql.sock
Restart the service, troubleshooting.

Solution is in my.cnf under

After the restart the service
