安装完后要进行数据库的初始化
cd /usr/local/mysql
bin/mysqld --initialize --user=mysql --datadir=/home/mysql/data --basedir=/usr/local/mysql --socket=/tmp/mysql.sock
编辑配置文件my.cmf
cp support-files/mysql.server /etc/init.d/mysql
chmod 755 /etc/init.d/mysql
chkconfig --add /etc/init.d/mysql
chkconfig mysql --level 235 on
echo "export PATH=/usr/local/mysql/bin:$PATH" >> /etc/profile
source /etc/profile
设定root密码
service mysql start
mysqladmin -u root password '123456'
set password for 'root'@'localhost'=password('123456');
use mysql;
show tables;
select host,user from user;
GRANT ALL PRIVILEGES ON . to 'root'@'192.168.%.%' identified by '123456' WITH GRANT OPTION;
flush privileges;
忘记root密码
UPDATE user SET authentication_string=password('123456') where USER='root';
update user set password=password('123456') where user='root';
