Centos7 安装 mysql 8

 

执行下面两条命令:

yum localinstall https://dev.mysql.com/get/mysql80-community-release-el7-1.noarch.rpm

yum install mysql-community-server

启动mysql (centos7以上):

 

启动mysql服务:

sudo systemctl start mysqld  

 

将mysql服务添加到开机启动:

sudo systemctl enable mysqld@server

加强版命令(可以显示更多信息):

systemctl status mysqld

service mysqld status

启动mysql(centos6 以下):

service start mysqld

关闭mysql:

systemctl stop mysqld

第一次启动mysql临时连接密码:
sudo grep 'temporary password' /var/log/mysqld.log
mysql设置密码:(要用到临时密码)
sudo mysql_secure_installation
以root用户权限 登录mysql:
 mysql -u root -p

创建一个新的root用户并启用远程登录:
CREATE USER 'root'@'%' IDENTIFIED BY 'new_rootpassword';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
更改加密方式(在mysql8中不更改navicat 连接不上mysql8):
ALTER USER 'root'@'%' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER;
刷新权限:
FLUSH PRIVILEGES;

开启端口
firewall-cmd --permanent –add-port=端口/tcp
重启 firewall
firewall-cmd --reload
