Granting SVN access to external users

Description: http://svnbook.red-bean.com/en/1.1/ch06s03.html

  1. Get the public ssh key of the user.
  2. Append the public ssh key to /home/svn/.ssh/authorized_keys.
  3. Insert
    command="svnserve -r /home/svn/repos -t --tunnel-user=<user>",no-port-forwarding,no-agent-forwarding,no-X11-forwarding,no-pty
    before the key. Now the user can only execute the SVN command, and any other command will be ignored.
  4. Commit the updated file to git: git commit -a

MySQL

  • MySQL is running on elk
  • For applications, allow access only from localhost
  • Log in via mysql -u root -p
  • MySQL commands:
# Create a user
CREATE USER <user> IDENTIFIED BY '<password>';

# Create a db
CREATE DATABASE <dbname>;

# Show grants
SHOW GRANTS FOR <user>@<host>;

# Grant full access on DB to user 
GRANT ALL ON <dbname>.* TO <user>@<host>;
# Example: Grant full access to user testwiki from localhost
GRANT ALL ON testwiki.* TO testwiki@localhost;

# Revoke access
REVOKE ALL ON testwiki.* FROM testwiki;

# Change Password
SET PASSWORD FOR 'bob'@'%.loc.gov' = PASSWORD('newpass');
