CentOS7之 yum方式安装MySQL5.7

                                                                         CentOS7之 yum方式安装MySQL5.7

1. 下载并安装MySQL官方的 Yum Repository

[root@localhost ~]# wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm

[root@localhost ~]# yum -y install mysql57-community-release-el7-11.noarch.rpm

2. 开始安装MySQL服务

[root@localhost ~]# yum -y install mysql-community-server

 查看MySQL版本号：

[root@localhost ~]# yum repolist all | grep mysql

3.启动自启mysql服务

[root@localhost ~]# systemctl  start  mysqld.service
[root@localhost ~]# systemctl  enable  mysqld.service

4.获取系统产生的随机密码，并重置密码

[root@localhost ~]# grep "password" /var/log/mysqld.log
。。。。。。。。。。。。。。。。。。。。。随机密码
[root@localhost ~]# mysql   -uroot   –p‘随机密码’
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'new password';

5. 因安装了Yum Repository，以后每次yum操作都会自动更新，需要卸载掉mysql57-community-release-el7-10.noarch

[root@localhost ~]# yum  -y  remove  mysql57-community-release-el7-10.noarch
