role and permission information, so I will briefly talk about the role and permission design ideas. As for code and implementation, I will not talk about it, because it has already been very detailed in the user, next, let's briefly introduce the content of this blog.
1. User implementation
(1) We have spent several blogs and introduced the implementation of users. Here, I put these three relationships in

Delete a user:
# Userdel-r name: delete the user's home directory
Some commands about the group:
# Groupadd group name add Group
-G GID group name specifies GID
-R: add a system Group
# Groupmod modify group information
-G GID: Group name: modify group GID
-N name: Group name: modify group name
# Add a password to the gpasswd group by group n

After the import is complete through dba_segments view verify that the tablespace of Segment_type index is still difficult to test, further view is because the index, which is automatically created when a primary key constraint is created for the database, is modified using the following command:
ALTER INDEX index_name REBUILD tablespace test_index;
Submitted to the business unit after completion, the result is that TEST2 u

When installing mysql, you usually generate a Super User root, which many people will continue to use later. Although this will be very convenient, the super user permission is too large, using it in all places is usual
Full access permissions for managing user mailboxes under exchange2013/2016In some cases, the company's "special" management needs for employees may require certain accounts to have the right to view and manage another account mailbox. In Exchange 2013, you can manage empowering operations through the ECP Admin Center or EMS. In this example, we want to give User01 full access to the User02 mailbox. Of cour

Recently, I used linux virtual hosts to learn about more advanced permission management in linux. If you want to delete the entire directory after installing the PHP program, you will find that apache users generate some files and ftp users cannot delete them.
In fact, there is a solution.
Method 1. User Group Control MethodFirst, add the virtual user (ftp user)
Python judges a user's permissions on a file,
In Python, we need to determine whether a file has read, write, and execution permissions for the current user. We can usually use the OS. access Function to implement this, for example:
# Judge the read permission OS. access (
However, if you want to determine whether a specified

In Oracle databases, user permissions are divided into two types (here we do not discuss dba or dbopr permissions, but only the permissions of common users ), system Privilege System permission and User Table Privilege User data T
Today, you need to configure trixbox web services to access databases on another machine. You must use the permissions granted to mysql users. Something you did not want to learnI had to use it. By the way, copy the content in the White Paper for future reference. An example is as follows:Grant all on *. * To asteriskuser @ "%" identified by 'amp109 ';Flush privileges;
The syntax of the grant statement is as follows:Grant privileges (columns)On whatTo
First, declare that, in general, you need to have the root permission in MySQL to modify the mysql password and grant permissions. Note: this operation is performed at the WIN command prompt, and phpMyAdmin is also applicable. User: phplamp user database: phplampDB1.MySQL command line to create a user login, first decl
User's division:Administrators, ordinary users, ordinary users are also sub-system users and general users, where system users are only used to run some specific processes cannot be used to log on to the system.The user is assigned to a basic group with the same name (the basic group is the default group, because the user can be added to many groups), and is assigned a
For example, when the webserver site directory is used to build the nginxwebserver for webtest, the default user and user group permissions are nginx: nginx, that is, nginx. the default user in conf and php-frm.conf is webtest: nginx: nginxnginx. conf: usernginxnginx; ph... for example, the webserver site directory is

There are two different ways to add users: using the GRANT statement or directly operating the MySQL authorization table. The better way is to use the GRANT statement, because they are more concise and seem to have fewer errors.The following example shows how to use a MySQL client to install a new user.
