记一次Centos安装mysql

下载rpm安装源

       rpm文件地址 : https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm

       通过wget命令下载 : whet  ‘上面的地址’

安装mysql源文件

       yum localinstall -y mysql57-community-release-el7-11.noarch.rpm

查看mysql源是否安装成功

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

安装mysql服务

         yum install -y mysql-commounity-server

查看mysql服务是否安装成功

         systemctl status mysqld

启动mysql

         systemctl start mysqld

修改root登录密码

         为了安全起见,mysql会随机生成一个密码

         grep 'temporary password' /var/log/mysqld.log

登录mysql

修改密码   mysql默认要求密码设置要包含大小写,数字,符号

         alter user ‘root’@’localhost’ identified by ‘Mysql123456^_^’;

设置为所有远程可以访问

         grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option;

设置开机启动

      systemctl enable mysqld

      systemctl daemon-reload

 

ok,大功告成^_^
