啟動mysql，擷取預設root密碼,登入mysql資料庫
[[email protected] data]# systemctl start mysqld.service
[[email protected] data]# grep 'temporary password' /var/log/mysqld.log
2018-11-16T15:15:20.149816Z 5 [Note] [MY-010454] [Server] A temporary password is generated for [email protected]: J/V3,F-pa;>X
[[email protected] data]# mysql -uroot -p
初始化mysql
[[email protected] data]# mysql_secure_installation
Securing the MySQL server deployment.
Enter password for user root:
The 'validate_password' component is installed on the server.
The subsequent steps will run with the existing configuration
of the component.
Using existing password for root.
Estimated strength of the password: 100
Change the password for root ? ((Press y|Y for Yes, any other key for No) : y
New password: $RFV5tgb
Re-enter new password: $RFV5tgb
Estimated strength of the password: 100
Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.
Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Success.
Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
Success.
By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
- Dropping test database...
Success.
- Removing privileges on test database...
Success.
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
Success.
All done!
修改root密碼，建立study使用者
### 初始化時已更改root密碼，這裡可以省略
# mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '$RFV5tgb';
### 這裡是避免SQLyog連接配接8.0報：Error No.2058 Plugin caching_sha2_password could not be loaded，後續工具更新後，再使用8.0新的加密方式
mysql> CREATE USER 'study'@'localhost' IDENTIFIED WITH mysql_native_password BY '^YHN7ujm';
### 授予study所有權限
mysql> GRANT ALL PRIVILEGES ON *.* TO 'study'@'localhost' WITH GRANT OPTION;
用SQLyog進行連接配接
ps: 由于mysql沒有開啟遠端連接配接，通過ssh連接配接跳轉
配置SSH Tunneling
配置ssh
填寫mysql連接配接資訊，注意host填：127.0.0.1
配置mysql連接配接
