First of all, after the Ambari is successfully installed normally, it may take a little longer; after the installation is complete, then you need to see what your IP address is, you can use the ip a command to check, and then you can log in to the web page to log in.
The URL entered at this time is the viewed ip:8080 , so that you can enter the login interface;
If you are using vbox to install, then the default ip is 127.0.0.1, directly enter 127.0.0.1:8080 to log in to the webpage;
If it is installed using VMware, then use the viewed ip, enter the web page and enter the viewed ip: 8080 to log in to the web page;
An interface for entering the login account and password will appear, as shown in the figure below:
The default user name/password for logging in to ambari is: admin/admin . Such a password is too simple. In order to prevent others from logging in to the system at will to modify the cluster configuration or host services, it is necessary to reset the admin login password. Let me tell you about it. 2 ways to change the password.
Method 1:
1. After successfully logging in with the password, click the admin option in the upper right corner and select Manager Ambari , as shown in the figure below:
2. Then select Users in the lower left corner, as shown in the figure below:
3. After entering Users, it will appear For multiple Usernames , select admin , as shown in the following figure:
4. After entering admin under Users, there is a Change Password option, you can modify and save the password by selecting it, it is best to change to a password that is easy to remember, so that it is not easy to forget . As shown below:
Method Two:
Sometimes when we delete the container, we will find that when we log in to ambari on the web page, it will prompt a password error. This is because deleting the container is equivalent to changing the default password. It is no longer the default password for logging in to ambari, so an error will occur. It is no longer the default admin, and we need to reset the password at this time.
