參考其他在線安裝mysql教程：
安裝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 啟動命令 systemctl start mysqld mysql 關閉 systemctl stop mysqld 查看mysql狀態 status mysqld.service 修改密碼 ALTER USER 'root'@'localhost' IDENTIFIED BY 'root';
1、創建工作目錄
鏈接: mysql-rpm 包鏈接地址 密碼: wnod
mkdir /usr/mysql 上傳安裝包mysql-5.7.25-1.el7.x86_64.rpm-bundle.tar 到工作目錄 執行解壓命令： tar -xvf mysql-5.7.25-1.el7.x86_64.rpm-bundle.tar
2、清除依賴：
yum remove mysql-libs 清除依賴
3、安裝：（若報錯，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、初始化啟動：
/usr/sbin/mysqld --initialize-insecure --user=root
5、啟動服務並設置后台運行模式
/usr/sbin/mysqld --user=root &
6、登錄MYSQL
mysql -uroot
7、重置 MySQL 密碼
alter user 'root'@'localhost' identified by 'root';
8、登錄mysql
mysql -uroot -proot
9、增加遠程登錄權限
mysql> use mysql; # 切換成mysql數據庫
mysql> select user,host from user; # 查詢用戶信息
10、設置遠程登錄權限
- 實現遠程連接（授權法）
mysql> update user set host='%' where host='localhost';
11、刷新配置信息
mysql> flush privileges;
12、測試
create database test;
