阿里雲centos7 安裝mysql

阿里雲centos7 安裝mysql

過程

1. 下載mysql的repo源

   wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
   sudo rpm -ivh mysql-community-release-el7-5.noarch.rpm
   

2. 安裝

   yum install mysql-server
   yum install mysql-devel
   yum install mysql
   rpm -qa | grep -i mysql
   

3. 啓動mysql

   service mysqld start
   

4. 設置開機啓動

   systemctl enable mysqld
   

查看初始密碼並修改

1. 打開文件my.cnf，位置在etc/my.cnf

2. 在my.cnf中的[mysqld]之後插入skip-grant-tables

3. 重啓mysql服務

   service mysqld restart						
   

4. 輸入

   mysql -u rooot -p								
   

   直接登錄，密碼是空

5. 修改密碼操作

   mysql> use mysql;
   
   mysql> show tables;
   
   select user,authentication_string from user;
   update mysql.user set authentication_string=password('123456') where user='root';
   flush privileges;
   exit
   

'123456’即新密碼

6. 刪掉my.cnf中的skip-grant-tables

7. 重啓服務

   service mysqld restart
