or repaired with the Mysqlcheck command. Specific method: Use command line to enter Mysql/bin directory, execute

Methods: Ensure that the sql_config.php username and password are correct in the Forum data directory. If the user forgets the password for the database, the password can be modified as follows:

If MySQL is running, stop first.

Start Mysql:bin/safe_mysqld--skip-grant-tables &

In combination with our actual situation, run under MySQL Command line Client:

Set password for root@localhost = Old_password (' 123456 ');

Method 2:

The following are the referenced contents: mysql> UPDATE mysql.user SET Password = Old_password (' newpwd ') -> WHERE Host = ' some_host ' and User = ' some_user '; mysql> FLUSH privileges;

The red section above please revise according to oneself actual situation.

Quote:

It is recommended to modify the maximum number of connections in the My.ini file and to change the mysql_connect () method to the Mysql_pconnect () method.
To modify Mysql_pconnect (), you can $pconnect = 0 in the sql_config.php of the forum's data directory; Whether the persistent connection is modified to $pconnect = 1; turn on anti-refresh

10055: No cache space available

Quote:

Check to see if your C-disk space is full, and remove any files that are not in use.

Can be in the background of the "Forum core settings", "Core function Settings" in "Process optimization" on, "GZIP compressed output" off.

Looked up the 10055 (no cache space available) The cause of the error, analyzed the My.ini configuration file, in the My.ini as follows:

The following are the referenced contents: Default-storage-engine=innodb Innodb_additional_mem_pool_size=2m Innodb_flush_log_at_trx_commit=1 innodb_log_buffer_size=1m innodb_buffer_pool_size=10m innodb_log_file_size=10m Innodb_thread_concurrency=8

Think you can increase the innodb_buffer_pool_size=10m like 100M or 1000M

The above is for the MYSQL5

If it is MYSQL4, you can add the following in My.ini:

The following are the referenced contents: #innodb_data_file_path = ibdata1:2000m;ibdata2:2000m #innodb_data_home_dir = C:ibdata #innodb_log_group_home_dir = C:iblogs #innodb_log_arch_dir = C:iblogs #set-variable = Innodb_mirrored_log_groups=1 #set-variable = innodb_log_files_in_group=3 #set-variable = innodb_log_file_size=5m #set-variable = innodb_log_buffer_size=8m #innodb_flush_log_at_trx_commit =1 #innodb_log_archive =0 #set-variable = innodb_buffer_pool_size=16m #set-variable = innodb_additional_mem_pool_size=2m #set-variable = innodb_file_io_threads=4 #set-variable = innodb_lock_wait_timeout=50

To the front of the #.

Start the MySQL service on this machine

If the service fails to start

There must be something wrong with your My.ini file.

MySQL service does not start properly

After you delete it, MySQL will run on its default configuration,

Then there's no problem.
