mysql5.7安装

• 安装新版mysql前，需将系统自带的mariadb-lib卸载

rpm -qa|grep mariadb

根据具体内容卸载

rpm -e --nodeps mariadb-libs-5.5.56-2.el7.x86_64

rpm -e --nodeps mariadb-server-5.5.56-2.el7.x86_64

rpm -e --nodeps mariadb-5.5.56-2.el7.x86_64

• 解压压缩包

tar -xvf mysql-5.7.28-1.el7.x86_64.rpm-bundle.tar

• 安装mysql-community-common-5.7.28-1.el7.x86_64.rpm

rpm -ivh mysql-community-common-5.7.28-1.el7.x86_64.rpm

• 安装mysql-community-libs-5.7.28-1.el7.x86_64.rpm

rpm -ivh mysql-community-libs-5.7.28-1.el7.x86_64.rpm

• 安装mysql-community-client-5.7.28-1.el7.x86_64.rpm

 rpm -ivh mysql-community-client-5.7.28-1.el7.x86_64.rpm

• 安装mysql-community-server-5.7.28-1.el7.x86_64.rpm

rpm -ivh mysql-community-server-5.7.28-1.el7.x86_64.rpm

• 初始化

mysqld --defaults-file=/etc/my.cnf --initialize --user=mysql

• 开启服务

service mysqld start

• 获取初始化密码

cat /var/log/mysqld.log

这一窜乱码一样的东西

 

 

 

• 登录mysql

mysql -uroot -peHNdO+EI,2vn

这时无论输入什么命令都提示

You must reset your password using ALTER USER statement before executing this statement.

修改密码就好

SET PASSWORD = PASSWORD('root');

• 最后修改下root密码

update mysql.user set authentication_string='root' where user='root';

就可以重新用新密码登录了
