Definition of Nginx User
Nginx user is required for the system able to access and modify folders and files related to our application and website. By default nginx uses www-data user for purpose of website and application, it is also the same user name that was used by the server of apache. Sometimes we need to change the user in our website for security reasons or we can also change the user for another purpose.
Overview of Nginx User
The resource of the user will represent the controller user account. We can also assign roles to the user for defining which actions the user is taking on to the controller and which environment is accessing. By default, all user contains the read permissions for licenses, roles, users and analytics. We can use the endpoint of platform roles into the nginx role rest API for extending the set of permissions that was the default. Nginx user is very important and useful to define and set the specified permission for the user. Using the user we can read the permission of the user.
How to change Nginx user?
As we know that it will be a popular open-source which was used in more than 400 million sites. Nginx users will use the technology suite for delivering and developing modern applications. The super user is around the world and is passionate about creating solutions by using the nginx and web development projects. We can define the user and group credentials that we have defined in the process of the worker. If the group is omitted then the group name equals the user is created.
Nginx is the web server of high performance which was used to serve the high performance the application which was scalable. User is used to serving the content of static, http requests, load balancing, and reverse balancing. The below steps show how we can change the user as follows.
- First, we are installing an nginx server on our system. We are considering ubuntu as an environment. In this step first, we are installing the nginx on our server. We can install the nginx by using the following command.
apt-get install nginx
2. After installing the server we can check the nginx installed version by using the following command as follows.
nginx –V
3. After installing the server in this step we are checking currently which user is used by the server by using the following command. In the below example we can see that multiple worker processes and the www-data user is used for all the processes, so we can say that our server is uses the default user.’
ps –ef | grep –i nginx
4. After installing the server and checking the version now we are opening the nginx configuration file for changing the user. In the below example we are changing the user from www-data to nginx_user as follows. In the below example we can see that we have commented on the www-data user and added nginx_user into the nginx configuration file.
5. After editing the configuration file and changing the user name in this step we are restarting the server to take the effect of changing the user onto the server. We have restrung the server by using the following command.
service nginx restart
How to add Nginx users?
To add the nginx user we need to install the nginx server. Below steps shows how to add the user are as follows.
- We are adding the nginx_service user into the configuration file. We are changing the user from nginx configuration file are as follows.
2. After editing the nginx configuration file and changing the user name from www-data to nginx_service now we are restarting the nginx server to take the effect of changing the user. We have restrung the server by using the following commands are as follows.
service nginx restart
Examples
The below example shows users as follows. We are creating the nginx_test user and using the same into nginx server.
- In first step we are checking the server is installed in our system. In our system we have already installed the nginx server so we have no need to install it again. We can check the status of server by using following command are as follows.
ps –ef | grep –i nginx
2. After checking the status of the server we are creating the OS user for adding the same in configuration file.
useradd -s /bin/false nginx_test
cat /etc/passwd | grep -i nginx_test
3. After creating the OS user in this step we are providing the specified permission of that user as follows. We are providing below permission to the nginx_test user are as follows.
4. After giving the required grants now we are opening the configuration file for changing the user. In below example we are changing the user from www-data user and added nginx_test into the configuration file are as follows.
5. After editing the configuration file and changing the user name from www-data to nginx_test now we are restarting the nginx server to take the effect of changing user. We are restring the nginx server by using service command are as follows.
service nginx restart
