Linux Normal User start Nginx

As we all know, Apache Port 80 is the system reserved port, if it is started by other non-root users, the error is as follows: ( -) Permission Denied:make_sock:could not bind to address [::]: the( -) Permission Denied:make_sock:could not bind to address0.0.0.0: theNo listening sockets available, shutting downunable to open logs because ordinary users can only use more than 1024 of the port, the port within 1024 can only be used by the root user. However, in order to avoid each boot through the root user, the set UID can be used to resolve the problem. This can be done at once. In the root user environment, do the following: CD .../apache/binChownRoot httpdchmodu+s httpd againsu-username to ordinary users, through .../apache/bin/apachectl start to why not chmod u+What about s apachectl? Because the set UID is only valid for binary files, and tail a bit apachectl found: Apachectl is a script file, look closely to find like the next sentence httpd='/home/....../apache/bin/httpd'It concludes that the Apachectl script starts the entire HTTPD service by starting the httpd file. Again cat httpd, there are a variety of unreadable garbled, CTRL+c After the output is finished, it is determined that httpd is a binary file. Last chmod u+s httpd can, of course, ensure that the owner of httpd is the root user, if not, execute:Chownroot httpd can be. Similarly, Nginx boot is also the same, with the root user into .... nginx/Sbin then chown root Nginxchmodu+s Nginx can then be started by ordinary users. Again, so does Tomcat. Of course, it is also possible to modify the default port to greater than 1024.
