yum安装mysql 5.6

检查系统是否安装其他版本的MYSQL数据

    yum list installed | grep mysql
    yum -y remove mysql-libs.x86_64

安装及配置

    wget http://repo.mysql.com/mysql-community-release-el6-5.noarch.rpm   
    rpm -ivh mysql-community-release-el6-5.noarch.rpm
    yum repolist all | grep mysql

    安装MYSQL数据库
    yum install mysql-community-server -y

    设置为开机启动(2、3、4都是on代表开机自动启动)
    chkconfig --list | grep mysqld
    chkconfig mysqld on

设置远程root

    启动mysql
    service mysqld start

    设置root密码
    mysql_secure_installation

    登陆root账号
    mysql -uroot -p 

    建立远程root用户
    mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
    mysql> flush privileges;

设置utf-8编码

    查看mysql原本编码：
    mysql> show variables like 'character%';

    设置编码
    # vi /etc/my.cnf

    如下(少补)：
    复制代码
    [mysqld]
    character-set-server=utf8 
    collation-server=utf8_general_ci 
    performance_schema_max_table_instances=400 
    table_definition_cache=400 
    table_open_cache=256

    # 修改
    sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

    [mysql]
    default-character-set = utf8

    [mysql.server]
    default-character-set = utf8


    [mysqld_safe]
    default-character-set = utf8


    [client]
    default-character-set = utf8

    

    重启mysql

    # service mysqld restart
    再次查看编码：

    # mysql -uroot -p
    mysql> show variables like 'character%';

    docker pull mysql:5.7.28

    运行容器
    docker run --name mysql -d --restart always -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 -v /usr/docker/mysql:/var/lib/mysql mysql:5.7.28
