Posted 2020-10-01

yum安装mysql

（新版本CentOS自带mariadb而不是mysql，所以要先卸载了，否则会冲突）

查找mariadb

rpm -qa | grep mariadb

卸载mariadb

rpm -e --nodeps mariadb-libs-5.5.52-1.el7.x86_64

 

安装mysql依赖

yum install vim libaio net-tools

 

下载mysql源

wget http://repo.mysql.com/yum/mysql-5.7-community/el/7/i386/mysql57-community-release-el7-10.noarch.rpm

安装mysql源

 sudo rpm -ivh mysql57-community-release-el7-10.noarch.rpm

开始安装mysql

sudo yum install mysql-server

过程全部输入y

 

安装完先启动服务systemctl start mysql.service

（停止服务systemctl stop mysql.service）

 

修改root密码步骤

进入

cd /var/log/

查找初始密码

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

登陆mysql

mysql -u root -p

修改root密码

update user set authentication_string=password(‘123abc‘) where user=‘root‘;
