Remove the permissions of the current user

Secondly, add, delete and modify new users:

1. Create user: # specify the chao user of ip:192.118.1.1 to log in to create user 'chao'@'192.118.1.1' identified by' 123 user # specify ip:192.118.1. The beginning of the chao user logs in to create user 'chao'@'192.118.1.%' identified by' 123 users. # specifies any chao user of ip to log in to create user 'chao'@'%' identified by' 123 users; 2. Delete user drop user 'username' @'IP address'; 3. Modify the user rename user 'username' @'IP address'to 'new user name' @'IP address'; 4. Change the password set password for 'username' @'IP address'= Password ('new password')

Next, authorize the current user

# View permissions show grants for 'user' @'IP address'# authorize chao users to query, insert and update db1.t1 files only grant select, insert,update on db1.t1 to "chao" @'%'; # means all permissions, except for the command grant, this command is available only for root.
