Of course, it is best to turn off the web server if the two units use the same domain name, and two units You can exist the same name, it may cause the user's mail, which is the same as two users, which is not suitable, so please do not use the official unit of the MAIL domain when establishing the unit of the test. .
(4.3). For formal units, you must use different MAIL suffixes.
(4.4). Determine the script location: / home / channelier
