Mysql安装与配置调优及修改root密码的方法

一、安装

apt-get install mysql-server 需要设置账号密码

apt-get isntall mysql-clientapt-get libmysqlclient-dev

root@xyz:~# netstat -tap | grep mysqltcp6    0   0 [::]:mysql       [::]:*         LISTEN   7510/mysqld -->安装成功

1. 编辑mysql配置文件，把其中bind-address = 127.0.0.1注释了

vi /etc/mysql/mysql.conf.d/mysqld.cnf

grant all on *.* to root@'%' identified by 'root' with grant option;flush privileges;

/etc/init.d/mysql restart

方法1：用SET PASSWORD命令

　　mysql -u root　　mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpass');

　　mysqladmin -u root password "newpass"

　mysqladmin -u root password oldpass "newpass"

mysql -u root　　mysql> use mysql;　　mysql> UPDATE user SET Password = PASSWORD('newpass') WHERE user = 'root';　　mysql> FLUSH PRIVILEGES;   在丢失root密码的时候，可以这样　　 mysqld_safe --skip-grant-tables&　　 mysql -u root mysql　　 mysql> UPDATE user SET password=PASSWORD("new password") WHERE user='root';　　 mysql> FLUSH PRIVILEGES;
