安装包下载地址

MySQL 8.0.22官网下载地址【下载】
MySQL 最新版官网下载地址【前往】

清理旧的mysql环境

1、查看当前安装的相关包

rpm -qa|grep -i mysql
也可能是
rpm -qa|grep -i mariadb

2.a、卸载相关包，如

rpm -e --nodeps mysql-community-server-8.0.22-1.el7.x86_64

2.b、删除相关目录，如

#查找mysql相关目录
find / -name mysql
rm -rf /var/lib/mysql /var/lib/mysql/mysql /usr/bin/mysql /usr/lib64/mysql /usr/share/mysql /var/log/mysqld.log

安装以及登录

3、解压tar安装包

tar -xvf mysql-8.0.22-1.el7.x86_64.rpm-bundle.tar

4、使用yum安装先行依赖包

yum -y install libaio
yum -y install perl
yum -y install net-tools

5、按顺序安装rpm包

rpm -ivh mysql-community-common-8.0.22-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-plugins-8.0.22-1.el7.x86_64.rpm  
rpm -ivh mysql-community-libs-8.0.22-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-8.0.22-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-8.0.22-1.el7.x86_64.rpm

6、查看、启动mysqld服务

systemctl status mysqld
systemctl start mysqld

7、第一次登录，使用数据库临时密码（必须先启动mysqld服务）

#查找临时密码
grep "temporary password" /var/log/mysqld.log

8、使用临时密码登录，并设置新密码

登录MySQL：mysql -uroot -p
如需使用简单密码(MySQL 8.0不支持)：set global validate_password_policy=0;set global validate_password_length=1;
设置密码：alter user 'root'@'localhost' identified by '123456';flush privileges;

9、创建远程登录账号

#MySQL 5.7
grant replication slave on *.* to repl@'192.168.73.%' identified by '123456';
flush privileges;#MySQL 8.0
create user repl@'192.168.73.%' identified  by '123456';
grant all privileges on *.* to repl@'192.168.73.%' with grant option;
flush privileges;

10、使用旧版密码插件

ALTER USER repl@'192.168.73.%' IDENTIFIED BY '123456' PASSWORD EXPIRE NEVER; 
ALTER USER repl@'192.168.73.%' IDENTIFIED WITH mysql_native_password BY '123456';
FLUSH PRIVILEGES;
