mysql在虚拟机上安装教程(mysql在虚拟机上安装教程视频)

虚拟机版本:12.1.0 build-3272444

centos版本: https://mirrors.tuna.tsinghua.edu.cn/centos/7.9.2009/isos/x86_64/CentOS-7-x86_64-DVD-2009.iso

mysql版本:https://mirrors.tuna.tsinghua.edu.cn/mysql/downloads/MySQL-5.7/mysql-5.7.34-linux-glibc2.12-x86_64.tar.gz

步骤如下:

新机安装mysql

1。linux安装

虚拟机安装忽略。大家自行安装下。

2。查看ip

ip a

3。关闭防火墙

systemctl stop firewalld

systemctl status firewalld#查看防火墙状态

4。截止开机启动

systemctl disable firewalld

5。关闭selinux

setenforce 0

改下:vi /etc/selinux/config

selinux = disabled

6。初始化vim和wget

yum -y install vim wget

下面开始安装MYSQL

1。删除mariadb依赖包。清理历史环境

rpm -qa|grep mariadb

#如果存在卸载

yum -y remove mariadb-libs

2。创建mysql用户

useradd mysql -s /sbin/nologin

3。创建相关目录

mkdir /database/ #软件目录

mkdir -p /data/mysql/ #数据库目录

mkdir -p /binlog/mysql/ #日志目录

4。设置目录的的所有者和所属组

chown -R mysql:mysql /database/ /data/ /binlog/

5。下载对应的二进制包 使用忽略证书–no-check-certificate下载

wget -P /database/ https://mirrors.tuna.tsinghua.edu.cn/mysql/downloads/MySQL-5.7/mysql-5.7.34-linux-glibc2.12-x86_64.tar.gz –no-check-certificate

6。解压

cd /database

tar -xvf mysql-5.7.34-linux-glibc2.12-x86_64.tar.gz

7。设置软连接

ln -s mysql-5.7.34-linux-glibc2.12-x86_64 mysql

8。 设置

改属组和属主

cd /database/mysql

chown -R mysql:mysql ./

环境变量设置

vim /etc/profile

增加 mysql的bin 路径

export PATH=/database/mysql/bin:$PATH

生效

source /etc/profile

验证 mysql -V

9。初始化数据库

查找依赖库

rpm -qa|grep libaio

如果没有就安装

yum -y install libaio-devel

初始化

mysqld –initialize-insecure –user=mysql –basedir=/database/mysql –datadir=/data/mysql/

10。新建配置mysql配置文件

vim /etc/my.cnf

[mysqld]

user=mysql

basedir=/database/mysql

datadir=/data/mysql

port=3306

socket=/tmp/mysql.sock

[mysql]

socket=/tmp/mysql.sock

准备mysql启动脚本

cd /database/mysql/support-files/

cp mysql.server /etc/init.d/mysqld

启动

chkconfig –add mysqld

chkconfig mysqld on

service mysqld start

防火墙放行3306端口

systemctl start firewalld

firewall-cmd –permanent –zone=public –add-port=3306/tcp

firewall-cmd –reload

firewall-cmd –list-all

设置mysql数据库的密码

use mysql;

update user set authentication_string=password('123456')where user='root';

#刷新数据库

flush privileges;

远程登录数据库设置

update user set host='%' where user='root' and host='localhost';

flush privileges;
