安装X plugin插件:
安装X plugin插件:
需要创建用户：
CREATE USER IF NOT EXISTS mysqlxsys@localhost IDENTIFIED WITH mysql_native_password AS 'password' ACCOUNT LOCK;
GRANT SELECT ON mysql.user TO mysqlxsys@localhost;
GRANT SUPER ON . TO mysqlxsys@localhost;
安装X plugin：
mysql -u root -p INSTALL PLUGIN mysqlx SONAME 'mysqlx.so';
mysqlsh -u root --sqlc -e "show plugins" --socket=/home/db/mysql/mysql.sock
执行一下更新：
Important The mysql.session user must exist before you can load X Plugin. mysql.session was added in MySQL version 5.7.19. If your data dictionary was initialized using an earlier version you must run the mysql_upgrade procedure. If the upgrade is not run, X Plugin fails to start with the error message There was an error when trying to access the server with user: mysql.session@localhost. Make sure the user is present in the server and that mysql_upgrade was ran after a server update..
mysql_upgrade -u root -p --socket=/home/db/mysql/mysql.sock
