Centos7系统下以RPM方式如何安装mysql-5.7

检查系统是否装有mariadb

rpm -qa | grep mariadb

卸载mariadb

强制卸载mariadb

rpm -e --nodeps mariadb-libs-5.5.35-3.el7.x86_64

安装mysql

rpm -ivh mysql-community-common-5.7.12-1.el7.x86_64.rpm

rpm -ivh mysql-community-libs-5.7.12-1.el7.x86_64.rpm

rpm -ivh mysql-community-client-5.7.12-1.el7.x86_64.rpm

rpm -ivh mysql-community-server-5.7.12-1.el7.x86_64.rpm

其中在安装 mysql-community-server-5.7.12-1.el7.x86_64.rpm 时可能会因为系统没有相应依赖文件而安装失败，如下

安装perl:

yum install perl



yum install libaio


安装完毕后启动mysql：

service mysqld start
查看初始密码：

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


用初始密码登录

mysql -uroot -p 
登陆后修改密码：

ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';
