linux下安装mysql(rpm安装)

Mysql 5.7.29安装步骤

1、首先卸载自带的Mysql-libs（如果之前安装过mysql，要全都卸载掉）

rpm -qa | grep -i -E mysql\|mariadb | xargs -n1 sudo rpm -e --nodeps

2、mysql 5.7.29.rpm安装包上传到linux服务器上

mysql 5.7.29 安装包 阿里云盘(https://www.aliyundrive.com/s/1pyJdfYBkEr)

01_mysql-community-common-5.7.29-1.el7.x86_64.rpm
02_mysql-community-libs-5.7.29-1.el7.x86_64.rpm
03_mysql-community-libs-compat-5.7.29-1.el7.x86_64.rpm
04_mysql-community-client-5.7.29-1.el7.x86_64.rpm
05_mysql-community-server-5.7.29-1.el7.x86_64.rpm

3、安装MySql

(1) 安装 mysql 依赖

sudo rpm -ivh 01_mysql-community-common-5.7.29-1.el7.x86_64.rpm
sudo rpm -ivh 02_mysql-community-libs-5.7.29-1.el7.x86_64.rpm
sudo rpm -ivh 03_mysql-community-libs-compat-5.7.29-1.el7.x86_64.rpm

(2) 安装mysql-client

sudo rpm -ivh 04_mysql-community-client-5.7.29-1.el7.x86_64.rpm

(3) 安装mysql-server

sudo rpm -ivh 05_mysql-community-server-5.7.29-1.el7.x86_64.rpm

(4) 启动mysql

sudo systemctl start mysqld

(5) 查看mysql密码

sudo cat /var/log/mysqld.log | grep password

4、 配置Mysql

​ 配置只要是root用户+密码，在任何主机上都能登录MySQL数据库。

(1) 用刚刚查到的密码进入mysql（如果报错，给密码加单引号）

mysql -uroot -p’password’

(2) 设置复杂密码(由于mysql密码策略，此密码必须足够复杂)

mysql> set password=password("Qs23=zs32");

(3) 更改mysql密码策略

mysql> set global validate_password_length=4;
mysql> set global validate_password_policy=0;

(4) 设置简单好记的密码

mysql> set password=password("000000");

(5) 进入msyql库

mysql> use mysql

(6) 查询user表

mysql> select user, host from user;

(7) 修改user表，把Host表内容修改为%

mysql> update user set host="%" where user="root";

(8) 刷新

mysql> flush privileges;

(9) 退出

mysql> quit;

5、安装成功
