二、创建mysql用户：

        useradd mysql -s /sbin/nologin -M

三、解压mysql-5.7.22-el7-x86_64.tar.gz ：

        tar xf mysql-5.7.22-el7-x86_64.tar.gz  && mv mysql-5.7.22-el7-x86_64.tar.gz  /opt/mysql

四、创建相关目录：

        cd /opt/mysql    mkdir {data,logs,etc}   mkidr logs/binlog

五、修改权限：

        cd /opt/ && chown -R mysql.mysql mysql

六、初始化数据库：

        cd /opt/mysql     
        ./bin/mysqld  --initialize --user=mysql --basedir=/opt/mysql --datadir=/opt/mysql/data
        记住最后提示的密码

七、修改my.cnf文件：

        echo > /etc/my.cnf     vi my.cnf 加入文档最后的内容

八、配置mysql服务：

        cd /opt/mysql && cp  support-files/mysql.server /etc/init.d/mysqld   
        修改权限chmod +x /etc/init.d/mysqld   
        编辑mysqld加入basedir=/opt/mysql   datadir=/opt/mysql/data
        chkconfig --add mysqld

九、启动mysql服务：

        service mysqld start 
        此时会报日志错误：Starting MySQL.2018-07-26T14:24:53.192088Z mysqld_safe error: log-error set to                   '/opt/mysql/logs/mysql-error.log', however file don't exists. Create writable for user 'mysql'.
                ERROR! The server quit without updating PID file (/opt/mysql/data/mysql.pid).
        原因是找不到logs下的mysql-error.log文件
        我们手动创建一个 
        touch /opt/mysql/logs/mysql-error.log&&chown mysql.mysql mysql-error.log
        再执行service mysqld start 即可

十、配置环境变量：

        cd &&vi .bash_profile  在PATH后加上/opt/mysql/bin，保存退出
        执行source .bash_profile

十一、登录数据库，修改密码：

        启动服务后，执行mysql -uroot -p 输入初始化时的密码
        执行show databases; 会报错ERROR 1820 (HY000): You must reset your password using ALTER USER          statement before executing this statement.
        执行set PASSWORD=PASSWORD('123456'); flush privileges 修改密码
        退出后用新密码可以重新登录

至此，Mysql-5.7.22二进制方式安装完成
