手册

安装后期的设置和测试
1. 初始化授权表
./scripts/mysql_install_db
mysql_install_db在mysql数据库里创建6个表(user,db,host,tables,priv,columns,priv和func)初始权限.这些权限允许MySQL root用户做任何事并允许任何人建立或使用一个名字以'test'或'test_'开始的数据库.
mysql_install_db仅在第一次安装MySQL时需要运行,若升级安装,可以跳过这一步.

cd mysql_installation_directory
bin/safe_mysqld &

3. 使用mysqladmin证实服务器正在运行
mysqladmin version
mysqladmin variables

4. 关掉服务器
BINDIR/mysqladmin -u root shutdown

5. 运行一些简单的测试证实服务器正在工作
BINDIR/mysqlshow
BINDIR/mysqlshow 表名

mysql -h host -u user -p
Enter password:******
若成功则出现 mysql> 提示符
在mysql>提示符下,输入help,显示帮助信; 输入quit退出连接.

2. 创建并使用一个数据库
mysql> CREATE DATABASE tmpDB;
创建数据库tmpDB

mysql> USE tmpDB; 或者 shell> mysql -h host -u user -p tmpDB;
