1.下载mqsql安装包

检查本地是否有安装mysql

yum list installed | grep mysql

如果有安装就卸载

yum -y remove mysql-libs.x86_64

通过wget下载安装包

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

将其安装到你的系统 repository 列表中

yum localinstall mysql-community-release-el7-5.noarch.rpm

验证是否安装成功

yum repolist enabled | grep "mysql.*-community.*"

通过yum安装mysql，Yum 会自动处理 MySQL 与其他组件的依赖关系

yum install mysql-community-server

查看安装目录

执行 #   rpm -qi mysql-community-server.x86_64 0:5.6.24-3.el7

执行 #    whereis mysql

可以看到 MySQL 的安装目录是 /usr/bin/

启动、停止、查看状态、设置开机自启

# systemctl start mysqld

# systemctl stop mysqld

# systemctl status mysqld

# systemctl enable mysqld

修改root用户默认密码

mysql -u root

mysql>use mysql;
mysql>update user set password=password("guxiong") where user="root";
mysql>flush privileges;
mysql>exit;
