#启动服务
service mysqld start
 
#测试连接
./mysql/bin/mysql -uroot
 
#加入环境变量,编辑 /etc/profile,这样可以在任何地方用mysql命令了

5.1 sqlyog连接时,报1130错误,是由于没有给远程连接的用户权限问题

直接授权

   GRANT ALL PRIVILEGES ON *.* TO ‘root’@'%’ IDENTIFIED BY ‘youpassword’ WITH GRANT OPTION;

    FLUSH PRIVILEGES;

 

5.2 安装时的一些错误

    -bash: ./scripts/mysql_install_db: /usr/bin/perl: bad interpreter: 没有那个文件或目录
    解决: yum -y install perl perl-devel

    Installing MySQL system tables..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
    解决:yum -y install libaio-devel

 

    centos 7.2 报错

    出现如下异常: 
  FATAL ERROR: please install the following Perl modules before executing /usr/bin/mysql_install_db: 
  Data::Dumper 
  解决方案: 
  ]# yum install -y perl-Module-Install.noarch

 

 5.3 设置root 密码

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;

 

 

6.1 配置环境变量

    vi + /etc/profile

    export PATH=....:/usr/local/mysql/bin
