## - !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

|
|
## - assuming your remote user is called "back", you have
|
|
## - to give sudoer rights to him as follow:
|
|
## -
|
|
## - visudo (edits /etc/sudoers file)
|
|
## -
|
|
## - add line:
|
|
## - back ALL = (root)NOPASSWD:/usr/bin/rsync
|
|
## -
|
|
## - on the remote database allow the congigured mysql user to
|
|
## - access the database from localhost an give him the follwing
|
|
## - privileges:
|
|
## - Select_priv
|
|
## - Lock_tables_priv
|
|
## - Show_view_priv
|
|
## - Event_priv
|
|
## - Process_priv (since MySQL 5.5)
|
|
## -
|
|
## - INSERT INTO user (Host,User,Password,Select_priv,Lock_tables_priv,Show_view_priv,Event_priv) VALUES('localhost','backup',password('backup'),'Y','Y','Y','Y');
|
|
## -
|
|
## - Since MySQL 5.5 - you also have to add process privileges (Process_priv = 'Y')
|
|
## - INSERT INTO user (Host,User,Password,Select_priv,Process_priv,Lock_tables_priv,Show_view_priv,Event_priv) VALUES('localhost','backup',password('backup'),'Y','Y','Y','Y','Y');
|
|
## -
|
|
## -
|
|
## - Since MySQL 5.7.x - you also have to add process privileges (Execute_priv = 'Y')
|
|
## - Password field is now: "authentication_string"
|
|
## - INSERT INTO user (Host,User,authentication_string,Select_priv,Process_priv,Lock_tables_priv,Show_view_priv,Event_priv,Execute_priv,ssl_cipher,x509_issuer,x509_subject) VALUES('localhost','backup',password('backup'),'Y','Y','Y','Y','Y','Y','','','');
|
|
## -
|
|
## - or if updating from older mysql version:
|
|
## -
|
|
## - UPDATE user SET Execute_priv = 'Y' WHERE User = 'backup';
|
|
## -
|
|
## -
|
|
## - FLUSH PRIVILEGES;
|
|
## -
|
|
## -
|
|
## - Since Version 5.6, giving password on command line is considered as insecure.
|
|
## - To avoid giving the password on command line, you can use an
|
|
## - encrypted option file instead.
|
|
## -
|
|
## - 1.) Create (encrypted) option file:
|
|
## -
|
|
## - Debian package installation:
|
|
## - $ mysql_config_editor set --login-path=local --socket=/var/run/mysqld/mysqld.sock --user=backup --password
|
|
## - $ Password:
|
|
## -
|
|
## - Source installation:
|
|
## - $ mysql_config_editor set --login-path=local --socket=/tmp/mysql.sock --user=backup --password
|
|
## - $ Password:
|
|
## -
|
|
## - 2.) Set environment variable mysql_credential_args="--login-path=local"
|
|
## - Now, the backup script uses the encrypted option file instead of (unencrypt) password
|
|
## - on command line.
