###初始化数据库

/usr/local/mysql5.5/scripts/mysql_install_db --user=mysql --datadir=/opt/mysqldata --basedir=/usr/local/mysql5.5/
cp ./support-files/my-huge.cnf /usr/local/mysql5.5/my.cnf

###修改my.cnf

[mysqld_safe]
#log-error=/opt/logs/mysql/mysqld.log  

[mysqld]
port            = 3306
socket          = /tmp/mysql.sock
datadir         = /opt/mysqldata/

wait_timeout=864000
interactive-timeout=864000
max_connections=2048

###启动

/usr/local/mysql5.5/bin/mysqld_safe --defaults-file=/usr/local/mysql5.5/my.cnf &

###关闭

/usr/local/mysql5.5/bin/mysqladmin --host=127.0.0.1 --port=3306 --user=xxx --password shutdown

设置密码

/usr/local/mysql5.5/bin/mysqladmin -uroot password '360buy'

参看密码是否生效
/usr/local/mysql/bin/mysql
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
进不去了，说明已经生效

使用密码登录

/usr/local/mysql5.5/bin/mysql -uroot -p

输入刚刚新建的密码，就可以进去了

添加root的远程访问

mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
mysql>flush privileges;
