CentOS6.5安装MySQL 5.5.61
CentOS6.5默认安装的MySQL版本是5.1,如果要安装5.5需要添加两个源
rpm -Uvh http://mirror.steadfast.net/epel/6/i386/epel-release-6-8.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
安装:
查看是否存在5.5:yum –enablerepo=remi,remi-test list mysql mysql-server
安装 yum –enablerepo=remi,remi-test install mysql mysql-server
启动:
/etc/init.d/mysqld start或service mysqld start
设置开机自启动:chkconfig –levels 345 mysqld on
设置密码:
在 Navicat for MySQL 下面直接执行 SET PASSWORD FOR ‘root’@’localhost’ = PASSWORD(‘newpass’); 就可以
方法1: 用SET PASSWORD命令
mysql -u root
mysql> SET PASSWORD FOR ‘root’@’localhost’ = PASSWORD(‘newpass’);
方法2:用mysqladmin
mysqladmin -u root password “newpass”
如果root已经设置过密码,采用如下方法
mysqladmin -u root password oldpass “newpass”
方法3: 用UPDATE直接编辑user表
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;
设置MySQL允许远程连接:
在本机先使用root用户登录mysql: mysql -u root -p”youpassword” 进行授权操作:
mysql>GRANT ALL PRIVILEGES ON *.* TO ‘root’@’%’ IDENTIFIED BY ‘youpassword’ WITH GRANT OPTION;
重载授权表:
FLUSH PRIVILEGES;
