阿里雲centos7安裝mysql 5.7.29

1.下載，進入mysql官網，查找需要的版本；

wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-community-server-5.7.29-1.el7.x86_64.rpm

2.安裝mysql包

rpm -ivh mysql-community-server-5.7.29-1.el7.x86_64.rpm

報如下圖錯誤，提示依賴mysql-community-client，mysql-community-common-5.7.29

 wget下載這些包，rpm -ivh *.rpm （安裝rpm包） #RPM軟件包管理器，-i 安裝rpm包，-vh顯示安裝進度；最終發現需要安裝這4個；

 

 3.開啟mysql服務

systemctl start mysqld.service

查看mysql狀態：systemctl status mysqld.service

 4.查看mysql臨時密碼,grep "password" /var/log/mysqld.log;

　　修改密碼：ALTER USER 'root'@'localhost' IDENTIFIED BY 'P@ssw0rd';

5.上述設置，無法使用navicat for mysql遠程連接mysql,需設置host為%，具體步驟如下：

mysql -uroot -pP@ssw0rd

use mysql; #使用mysql數據庫

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

flush privileges;
