一、安裝前準(zhǔn)備
查看數(shù)據(jù)庫(kù)版本命令： mysql --version
mysql-community-common-8.0.17-1.el7.x86_64.rpm
mysql-community-libs-8.0.17-1.el7.x86_64.rpm
mysql-community-client-8.0.17-1.el7.x86_64.rpm
mysql-community-server-8.0.17-1.el7.x86_64.rpm
二、安裝RPM包
依次安裝上述RPM包，前后安裝包為依賴關(guān)系。
# rpm -ivh mysql-community-common-8.0.17-1.el7.x86_64.rpm
# rpm -ivh mysql-community-libs-8.0.17-1.el7.x86_64.rpm
# rpm -ivh mysql-community-client-8.0.17-1.el7.x86_64.rpm
# rpm -ivh mysql-community-server-8.0.17-1.el7.x86_64.rpm
三、 查詢r(jià)oot賬戶初始密碼
mysql 8.0版本的初始密碼默認(rèn)非空，安裝時(shí)自動(dòng)生成，存儲(chǔ)在/var/log/mysqld.logzhon中。
# rpm -ivh mysql-community-common-8.0.17-1.el7.x86_64.rpm
# rpm -ivh mysql-community-libs-8.0.17-1.el7.x86_64.rpm
# rpm -ivh mysql-community-client-8.0.17-1.el7.x86_64.rpm
# rpm -ivh mysql-community-server-8.0.17-1.el7.x86_64.rpm
四、修改root密碼
修改密碼默認(rèn)有安全性要求，對(duì)密碼復(fù)雜度有控制。
mysql> alter user 'root'@'localhost' identified by 'redhat';
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
mysql> alter user 'root'@'localhost' identified by '1qaz!QAZ';
Query OK, 0 rows affected (0.15 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
五、查看當(dāng)前用戶配置信息
mysql> show databases;
mysql> use mysql;
mysql> select user,host,plugin from user;
六、新建一用戶用于遠(yuǎn)程訪問(wèn)
mysql> create user 'wangwang'@'%' identified by '1qaz!QAZ';
Query OK, 0 rows affected (0.08 sec)
mysql> grant all on *.* to 'wangwang'@'%';
Query OK, 0 rows affected (0.12 sec)
mysql> select user,host,plugin from user;
該賬戶的plugin加密方式為caching_sha2_password， MySQL 8.0前的客戶端在連接 MySQL 8.0服務(wù)器時(shí)會(huì)出現(xiàn) Authentication plugin 'caching_sha2_password' cannot be loaded 的錯(cuò)誤（需要更該為mysql_native_password）。
七、修改加密方式
修改加密規(guī)則
mysql> alter user 'wangwang'@'%' identified by '1qaz!QAZ' password expire never;
Query OK, 0 rows affected (0.17 sec)
更新用戶密碼
mysql> alter user 'wangwang'@'%' identified with mysql_native_password by '1qaz!QAZ';
Query OK, 0 rows affected (0.04 sec)
保存更改
mysql> flush privileges;
Query OK, 0 rows affected (0.05 sec)
查詢信息
mysql> select user,host,plugin from user;
八、測(cè)試連接
可以使用Navicat進(jìn)行測(cè)試。
