Mysql configuration under Lampp xampp Linuxubuntu

Default execution Lampp/xampp after Ubuntu, a series of configurations for MySQL are required for better operation

MySQL configuration file path under LAMPP:

/opt/lampp/etc/my.cnf

1 Configuring the default character Set

Added under Mysqld

Character-set-server=utf8

Init_connect = ' SET NAMES UTF8 '

Add under Client

Default-character-set =utf8

Jiangzi OK, try to use the JetBrains Data Connection tool insert a Chinese data try it, see if you can insert Chinese UTF8 character data normally

2 Modifying the default allowed execution of the largest SQL script size

Why should I set this project?

If you have a SQL script that is larger than the default value, it will not be able to execute anymore.

The same my.cnf.

Items: Under Mysqld and Mysqldump

max_allowed_packet=500m

Settings can

3 Migrating the default database folder path

Just loaded LAMPP mysql its path is under/OPT, which is the system folder, we need to migrate it to the specified private database folder

Copy the default folder first

?

1	sudocp -rp /opt/var/mysql/home/xx

Then modify the settings in the MY.CNF

Client Item Sock Link file

Sock=/home/xx/mysql/mysql.sock

MYSQLD Item Sock Link file

Sock=/home/xx/mysql/mysql.sock

Add a Data folder variable to the next row in the Plugin_dir variable

Datadir=/home/xx/mysql

Complete database document path migration;

4 build linux MySQL client link command configuration

?

1	sudoapt-get install-y mysql-client-core-5.5

Install the sock link after the configuration.

Delete the original system mysql command path

?

1	sudorm-rf /var/run/mysqld

Rebuilding folders

?

1	sudomkdir/var/run/mysqld

Rebuilding a soft connection

?

1	sudoln-s /home/xx/mysql/mysql.sock /var/run/mysqld/mysqld.sock

Then try the MySQL command directly under the command line.

5 Set InnoDB shared file index Table self-increment space

If not set, will also cause a variety of inexplicable ibdata1 start error

MY.CNF settings

Innodb_data_home_dir=/home/xx/mysql

innodb_data_file_path=ibdata1:5000m;ibdata2:5000m;ibdata3:1000m;ibdata4:1000m:autoextend:max:5000m

The actual development of this item does not need to be modified

This means that each time the self-increment table space 1000M, but the maximum value is 5000M, can be set according to their actual disk space, the lowest value is best not to use the default 10M or the actual production environment used easily fail

It's over here.
