3.2.3初始化MySQL数据库文件

上述配置完毕后,就可以初始化数据库文件了,这个步骤其实也可以在编译安装MySQL之后就操作,只不过放到这里更合理一些.

(1)初始化MySQL数据库

初始化数据库的核心命令为:

application/mysql/scripts/mysql_install_db –basedir=/application/mysql/ –datadir=/application/mysql/data –user=mysql

提示:–basedir=/application/mysql/为MySQL的安装路径,–datadir为数据文件目录.另,注意mysql_install_db和MySQL5.1的路径不同,MySQL5.1不在MySQL bin路径下了.

整个初始化的操作过程为:

[root@oldboy mysql-5.6.34]# /application/mysql/scripts/mysql_install_db –basedir=/application/mysql/ –datadir=/application/mysql/data –user=mysql

#<==初始化mysql数据库文件,会有很多信息提示,如果没有ERROR级别的错误,有两个OK的字样,表示初始化成功,否则就要解决初始化的问题.

To start mysqld at boot time you have to copy

support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !

To do so,start the server,then issue the following commands:

/application/mysql//bin/mysqladmin -u root password ‘new-password’

/application/mysql//bin/mysqladmin -u root -h oldboy password ‘new-password’

Alternatively you can run:

/application/mysql//bin/mysql_secure_installation

which will also give you the option of removing the test

databases and anonymous user created by default.? This is

strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

cd . ; /application/mysql//bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

cd mysql-test ; perl mysql-test-run.pl

Please report any problems at http://bugs.mysql.com/

http://www.mysql.com

###请注意如下几行英文的说明

New default config file was created as /application/mysql//my.cnf and

will be used by default by the server when you start it.

You may edit this file to change server settings

#从上文说明中可以指导mysql的默认配置文件已经变到了/application/mysql//my.cnf

WARNING: Default config file /etc/my.cnf exists on the system

This file will be read by default by the MySQL server

If you do not want to use this,either remove it,or use the

–defaults-file argument to mysqld_safe when starting the server
