mysql安装使用

==================

 solaris中mysql安装

 1 增加mysql用户

　groupadd user; useradd -G mysql mysql

 2 安装 pkgadd -d mysql-5.5.38-solaris10-x86_64.pkg

 3 增加配置文件/opt/mysql/mysql/etc/my.cnf

 cp ./support-files/my-medium.cnf ./etc/my.cnf

----------------

配置文件的读取优先顺序：

/etc/my.cnf

/etc/mysql/my.cnf

/opt/mysql/mysql/etc/my.cnf

~/.my.cnf

-----------------------

 修改./etc/my.cnf

[mysqld]
basedir=/opt/mysql/mysql
datadir=/opt/mysql/mysql/data
character-set-server=gb2312

[mysql]

default-character-set=gb2312

[client]

default-character-set=gb2312

 4 导入权限数据库

./scripts/mysql_install_db --defaults-file=./etc/my.cnf --user=mysql &

5 启动mysql数据库服务

/etc/init.d/mysql start

或

bin/mysqld_safe &

===========================

1. 创建用户

mysql> use mysql;

mysql> insert into user(host, user, password) values('%', 'CM', PASSWORD('CM'));

mysql> flush privileges;

mysql> create user 'dell'@'::1' identified by 'secret';

mysql> grand select on mydb.* to 'dell'@'::1';

2. 授权

GRANT ALL PRIVILEGES ON test.* TO 'asn'@'%';

注：（创建用户并授权）

GRANT ALL PRIVILEGES ON *.* TO 'asn'@'%' IDENTIFIED BY 'asn';

mysql> flush privileges;

2. 给用户root设置密码

/opt/mysql/mysql/bin/mysqladmin -u root password 'root'

直接在mysql数据库的用户表user中该用户密码

mysql> use mysql;

mysql> update user set password=PASSWORD('root') where user='root';

mysql> flush privileges;
