1.下载MySQL官方的 Yum Repository

wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm

2.安装 Yum Repository

yum -y install mysql57-community-release-el7-10.noarch.rpm

3 使用 yum 安装 MySQL

yum -y install mysql-community-server

若出现错误

Public key for mysql-community-libs-compat-5.7.41-1.el7.x86_64.rpm is not installed

Failing package is: mysql-community-libs-compat-5.7.41-1.el7.x86_64
GPG Keys are configured as: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

解决方法

rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022

然后继续安装mysql的服务：

yum install mysql-server

安装成功

4 启动MySQL

systemctl start  mysqld.service

5 查看mysql运行状态

6 获取 root 用户的密码

grep "password" /var/log/mysqld.log

7 进入数据库,使用刚才获取到的密码登录

mysql -u root -p

8 设置密码

ALTER USER 'root'@'localhost' IDENTIFIED BY '!Qaz123456';

9 添加root用户远程访问数据库

grant all on *.* to root@'%' identified by '!Qaz123456';

10 刷新访问权限的设置

flush privileges;

11 重启MySQL服务

systemctl restart mysqld.service

12 开启 mysql 的 binlog

1. 修改 /etc/my.cnf

vim /etc/my.cnf

[mysqld]
#binlog⽇日志存放路路径】 
log-bin=/var/lib/mysql/mysql-bin 
#⽇日志中会记录成每⼀一⾏行行数据被修改的形式】 
binlog-format=ROW 
#指定当前机器器的服务ID(如果是集群，不不能重复)】
server_id=1 

2. 重启 mysql

systemctl restart mysqld.service

3. 进入MySQL控制台，验证binlog是否打开

show variables like '%log_bin%';

4. 进入指定的 binlog 路径查看是否生产 binlog

cd /var/lib/mysql/
