  mysql 在线安装教程一

安装mysql wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
wget --no-check-certificate http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
yum localinstall mysql57-community-release-el7-8.noarch.rpm
yum repolist all | grep mysql 
yum install -y yum-utils
yum-config-manager --enable mysql57-community 
yum-config-manager –disable mysql56-community
yum repolist all | grep mysql 
yum install mysql-server
mysql 启动命令 systemctl start mysqld mysql 关闭 systemctl stop mysqld 
查看mysql状态 status mysqld.service
修改密码 ALTER USER 'root'@'localhost' IDENTIFIED BY 'root';

1、创建工作目录

  链接: mysql-rpm 包链接地址  密码:  wnod

mkdir /usr/mysql
上传安装包mysql-5.7.25-1.el7.x86_64.rpm-bundle.tar 到工作目录

执行解压命令:
tar -xvf mysql-5.7.25-1.el7.x86_64.rpm-bundle.tar

2、清除依赖:

yum remove mysql-libs  清除依赖

3、安装:(若报错,在后面加上 --nodeps)

- rpm -ivh mysql-community-common-5.7.25-1.el7.x86_64.rpm 
- rpm -ivh mysql-community-libs-5.7.25-1.el7.x86_64.rpm
- rpm -ivh mysql-community-libs-compat-5.7.25-1.el7.x86_64.rpm
- rpm -ivh mysql-community-client-5.7.25-1.el7.x86_64.rpm
- rpm -ivh mysql-community-server-5.7.25-1.el7.x86_64.rpm

4、初始化启动:

/usr/sbin/mysqld --initialize-insecure --user=root

5、启动服务并设置后台运行模式

/usr/sbin/mysqld --user=root &

6、登录MYSQL

mysql -uroot

7、重置 MySQL 密码

alter user 'root'@'localhost' identified by 'root';

8、登录mysql

mysql -uroot -proot

9、增加远程登录权限

mysql> use mysql;  # 切换成mysql数据库
mysql> select user,host from user; # 查询用户信息

10、设置远程登录权限

  • 实现远程连接(授权法)
mysql> update user set host='%' where host='localhost';

11、刷新配置信息

mysql> flush privileges;

12、测试

create database test;
