Cenost7 Mysql5.7 安装 并打开远程访问
MySql5.7
- 下载MySql yum 源
wget https://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm
- 安装repo
rpm -ivh mysql57-community-release-el7-9.noarch.rpm
- 查看可安装的版本
yum repolist all| grep mysql
- 5.7 已经启用,想要修改其他版本源,可以直接修改对应的yum.repo文件
vim /etc/yum.repos.d/mysql-community.repo
- 安装 mysql
yum install -y mysql-community-server
太慢了...
-
现在用的时清华源 换成阿里试试
-
搞不懂是因为什么,一开始是最快速度然后一直往下降,被限速一样
-
先去百度一下 嘿嘿 初始用yum安装发现下载非常慢,就考虑本地用迅雷下载rpm方式安装
-
去官网下载rpm 包(4个哦)
wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-community-server-5.7.28-1.el7.x86_64.rpm
wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-community-client-5.7.26-1.el7.x86_64.rpm
wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-community-common-5.7.26-1.el7.x86_64.rpm
wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-community-libs-5.7.26-1.el7.x86_64.rpm
对了,原文博主是用迅雷下的,为什么我用wget下的这么快
-
舒服了
-
总算可以装了

安装顺序
安装顺序 common-->libs-->client-->server
rpm -ivh mysql-community-common-5.7.26-1.el7.x86_64.rpm --force --nodeps
rpm -ivh mysql-community-libs-5.7.26-1.el7.x86_64.rpm --force --nodeps
rpm -ivh mysql-community-client-5.7.26-1.el7.x86_64.rpm --force --nodeps
rpm -ivh mysql-community-server-5.7.28-1.el7.x86_64.rpm --force --nodeps
配置
- 启动服务
systemctl start mysqld
- 找到初始密码
cat /var/log/mysqld.log |grep password
密码最好手打,别复制
- 更改密码 远程访问权限
ALTER USER 'root'@'localhost' IDENTIFIED BY 'Root123@';
grant all privileges on *.* to 'root'@'%' identified by 'Root123@' with grant option;
- firewalld iptables
- win10测试 cmd下执行telnet 192.168.10.130 3306
iptables 与 firewalld 都不是真正的防火墙, 它们都只是用来定义防火墙策略的防火墙管理工具,是一种服务。
systemctl stop firewalld
systemctl disable firewalld
iptables -F
iptables -X
iptables -Z
/usr/sbin/iptables-save
