**二、安装配置**

1、修改  vi /etc/my.cnf

[client]
    port=3306
    socket=/var/lib/mysql/mysql.sock
     
    [mysqld]
    port=3306
    user=mysql
    socket=/var/lib/mysql/mysql.sock
    basedir=/usr/local/mysql
    datadir=/usr/local/mysql/data

**2、创建mysql组与用户**

groupadd mysql
    useradd -g mysql mysql

**3、初始化mysql**

/usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/

**  执行结果如下【**root@localhost: 跟着的是**初始密码。记下，后面用到 】：**

> 2019-09-10T10:24:51.816431Z 0 \[System\] \[MY-013169\] \[Server\] /usr/local/mysql/bin/mysqld (mysqld 8.0.17) initializing of server in progress as process 11400  
> 2019-09-10T10:24:56.404516Z 5 \[Note\] \[MY-010454\] \[Server\] A temporary password is generated for root@localhost: **)sTNHf/sp7er**  
> 2019-09-10T10:24:58.587884Z 0 \[System\] \[MY-013170\] \[Server\] /usr/local/mysql/bin/mysqld (mysqld 8.0.17) initializing of server has completed

**4、创建sock文件夹与命令链接**

mkdir -p /var/lib/mysql ; chown -R mysql:mysql /var/lib/mysql
    ln -s /usr/local/mysql/bin/mysql /usr/bin

**5、启动服务**

/usr/local/mysql/support-files/mysql.server start

修改密码 ，我这里的新密码是123456

ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';

**7、开启远程访问**

use mysql;
    update user set host='%' where user='root';
    flush privileges; 
    exit;

**8、关闭防火墙**

systemctl stop firewalld.service            #停止firewall        
    systemctl disable firewalld.service         #禁止firewall开机启动

9、配置成服务并开机启动

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
    chkconfig mysql on
    chkconfig --add mysql

这样可以使用命令

service mysql start

service mysql stop

**二、远程访问**
