  • centos7下安装mysql6初始化安装密码

    1.先停止数据库服务器

    service  mysqld stop

    2.vim /etc/my.cnf

    3.配置文件添加skip-grant-tables

    [root@VM_0_8_centos ~]# vim /etc/my.cnf
    
    # For advice on how to change settings please see
    # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
    
    [mysqld]
    #
    # Remove leading # and set to the amount of RAM for the most important data
    # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
    # innodb_buffer_pool_size = 128M
    #
    # Remove leading # to turn on a very important data integrity option: logging
    # changes to the binary log between backups.
    # log_bin
    #
    # Remove leading # to set options mainly useful for reporting servers.
    # The server defaults are faster for transactions and fast SELECTs.
    # Adjust sizes as needed, experiment to find the optimal values.
    # join_buffer_size = 128M
    # sort_buffer_size = 2M
    # read_rnd_buffer_size = 2M
    datadir=/var/lib/mysql
    socket=/var/lib/mysql/mysql.sock
    skip-grant-tables                       此处!!!!!!
    # Disabling symbolic-links is recommended to prevent assorted security risks
    symbolic-links=0

    4.重启数据库

     systemctl restart mysql

    5.登录数据库

    mysql -uroot -p

    如果询问密码,直接空密码登录

    6.set password for root@localhost = password('123456');括号里面的密码你自己修改。

    7.mysql -uroot -p123456 登录成功

    题外话:

    GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' 设置允许远程访问

    firewall-cmd --zone=public --add-port=3306/tcp --permanent  开放3306端口
