yum安装

参考 http://dev.mysql.com/doc/refman/5.7/en/linux-installation-yum-repo.html

启动mysqld服务：sudo service mysqld start

检查服务状态：sudo service mysqld status

连接服务器：mysql -uroot -p

 

 

启动服务：service mysql start | | restart

 检查配置：chkconfig --list | grep mysqld

设置开机自动启动：chkconfig mysqld on

设置root用户密码：mysqladmin -u root password ‘root‘

 

安全模式下重置密码：copy自 http://www.linuxidc.com/Linux/2014-03/98718.htm

启动mysql：
#/etc/init.d/mysql start

启动成功后查看mysql进程信息，获取mysqld_safe的安装目录：
#ps -ef | grep -i mysql
root 3466 1 0 01:45 pts/1 00:00:00 /bin/sh /usr/bin/mysqld_safe --datadir=/var/lib/mysql --pid-file=/var/lib/mysql/BSC.TEST.pid
mysql 3569 3466 16 01:45 pts/1 00:00:00 /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib64/mysql/plugin --user=mysql --log-error=/var/lib/mysql/BSC.TEST.err --pid-file=/var/lib/mysql/BSC.TEST.pid
root 3597 3105 0 01:45 pts/1 00:00:00 grep -i mysql

以安全方式启动mysql:
#/usr/bin/mysqld_safe --skip-grant-tables >/dev/null 2>&1 &

启动mysql：
#/usr/bin/mysql -u root mysql

更新密码：
update mysql.user set authentication_string=password(‘root‘) where user=‘root‘ and Host =‘localhost‘;

 

登录：mysql -u root -p

mysql配置文件路经：/ect/my.cnf
