一、安装

bash 复制代码

sudo yum remove -y mysql mysql-server mysql-community-server
sudo rm -rf /var/lib/mysql
sudo rm -rf /etc/my.cnf

bash 复制代码

sudo rpm -ivh https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm

bash 复制代码

sudo yum install -y mysql-community-server --nogpgcheck

bash 复制代码

sudo systemctl start mysqld
sudo systemctl enable mysqld

bash 复制代码

sudo grep 'temporary password' /var/log/mysqld.log

会看到密码输出类似：

bash 复制代码

A temporary password is for root@localhost: xxxxxx

bash 复制代码

mysql -u root -p

粘贴5 的初始密码进入。

然后执行（把 你的密码 换成你自己的）：如果要远程登录root

bash 复制代码

ALTER USER 'root'@'localhost' IDENTIFIED BY '你的密码';
FLUSH PRIVILEGES;
exit;

bash 复制代码

mysql -u root -p

bash 复制代码

CREATE USER 'account'@'%' IDENTIFIED BY '你的密码';
GRANT ALL ON accounting.* TO 'account'@'%';
FLUSH PRIVILEGES;
exit;

bash 复制代码

sudo firewall-cmd --add-port=3306/tcp --permanent
sudo firewall-cmd --reload

bash 复制代码

mysql -V

输出：

bash 复制代码

mysql Ver 8.0.36 for Linux on x86_64 ...
