Linux环境下源码编译方式安装MySQL5.1(2)

2. 创建数据库

创建目录并修改权限：

[root@mysqldb2 local]# cd /data

[root@mysqldb2 data]# mkdir mysqldata

[root@mysqldb2 data]# cd mysqldata

[root@mysqldb2 mysqldata]# mkdir 3306

[root@mysqldb2 mysqldata]# cd 3306

[root@mysqldb2 3306]# mkdir data binlog tmp innodb_ts innodb_log

[root@mysqldb2 3306]# cd /data

[root@mysqldb2 data]# chown -R mysql:mysql mysqldata

创建数据库：

[root@mysqldb2 local]# cd mysql/

[root@mysqldb2 mysql]# bin/mysql_install_db --user=mysql --datadir=/data/mysqldata/3306/data

Installing MySQL system tables...

Filling help tables...

OK

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:

/usr/local/mysql/bin/mysqladmin -u root password 'new-password'

/usr/local/mysql/bin/mysqladmin -u root -h mysqldb2 password 'new-password'

Alternatively you can run:

/usr/local/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 /usr/local/mysql ; /usr/local/mysql/bin/mysqld_safe &

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

cd /usr/local/mysql/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/local/mysql/bin/mysqlbug script!

启动数据库：

[root@mysqldb2 mysql]# mysqld_safe --defaults-file=/data/mysqldata/3306/my.cnf &

设置超级用户密码：

[root@mysqldb2 mysql]# mysqladmin -uroot password 'verysafe' -S /data/mysqldata/3306/mysql.sock

可以通过netstat或ps等命令查看mysqld是否正常加载，由于默认指定mysqld端口号为3306，因此通过netstat查看是否存在3306端口即可，例如：

[root@mysqldb2 mysql]# netstat -lnt
