centOS7 安装mysql-5.7.20-1.el7.x86_64.rpm-bundle.tar

在虚拟机上安装mysql走了不少弯路,在此备份。。。

首先感谢下这几篇博客提供的帮助:

1.官网下载mysql:

mysql-5.7.20-1.el7.x86_64.rpm-bundle.tar

mysql分了好多版本,有linux和ubuntu等等的,个人感觉最方便的是红帽;

2.解压:

tar -xvf mysql-版本号

解压后有很多个,但是我们只需要安装4个(有项目依赖,需要关注下顺序);

3.安装:

安装前先卸载自带的mariadb-lib(必须卸载,不然会碰到依赖错误,别问我怎么知道的。。。)

备注:如果删不掉的话可以试试这条命令:yum remove mysql-libs

然后依次安装:

 

  #rpm -ivh mysql-community-common-版本.el6.x86_64.rpm

 

  #rpm -ivh mysql-community-libs-版本.el6.x86_64.rpm

 

  #rpm -ivh mysql-community-client-版本.el6.x86_64.rpm

 

  #rpm -ivh mysql-community-server-版本.el6.x86_64.rpm

 

4.数据库初始化:

为了保证数据库目录为与文件的所有者为 mysql 登陆用户,如果你是以 root 身份运行 mysql 服务,需要执行下面的命令初始化
mysqld --initialize --user=mysql

systemctl start mysqld.service

mysql -uroot -p
第一次不用输入密码直接登录,如果输入密码了或者碰到如下错误:

Access denied for user 'root'@'localhost' (using password:YES)

请参考这篇博客解决:

http://blog.csdn.net/skywalker_leo/article/details/47274441;

[root@wshCentOS ~]# mysql -uroot -proot123

修改之后登录成功,可能需要重置密码;

以上;
