In this issue, the editor will bring you the default number of connections about how to modify MySQL 5.0in Linux. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

The manual compiled version of mysql 5.0.33 is taken as an example:

Vi / usr/local/mysql/bin/mysqld_safe

Find safe_mysqld and edit it, find the two lines where mysqld starts, and add parameters at the end:

-O max_connections=1500

Specifically, it is the following location:

To specify in the scarlet letter:

Then $NOHUP_NICENESS $ledir/$MYSQLD

$defaults-basedir=$MY_BASEDIR_VERSION

-- datadir=$DATADIR $USER_OPTION

-- pid-file=$pid_file

-- skip-external-locking

-O max_connections=1500

> > $err_log 2 > & 1 else

Eval "$NOHUP_NICENESS $ledir/$MYSQLD

$defaults-basedir=$MY_BASEDIR_VERSION

-- datadir=$DATADIR $USER_OPTION

-- pid-file=$pid_file

-- skip-external-locking $args

-O max_connections=1500 > >

$err_log 2 > & 1 "

Save.

# service mysqld restart

# / usr/local/mysql/bin/mysqladmin-uroot-p variables

After entering the password of the root account, you can see

Max_connections 1500 means that the new changes have come into effect.

There is another way:

Modify the original code:

Unlock the original code of MySQL, enter the sql directory inside and modify d.cc to find the following line:

{"max_connections", OPT_MAX_CONNECTIONS

"The number of simultaneous clients allowed." (gptr*) & max_connections

(gptr*) & max_connections, 0, GET_ULONG, REQUIRED_ARG, 100,1, 16384, 0,1

0}

Change it to:

{"max_connections", OPT_MAX_CONNECTIONS

"The number of simultaneous clients allowed." (gptr*) & max_connections

(gptr*) & max_connections, 0, GET_ULONG, REQUIRED_ARG, 1500, 1, 16384, 0, 1

0}

Save and exit, and then. / configure; make;make install can get the same effect.
