Younger brother on the phone to try the nginx, the purpose is to want to put the 2 servers, using their native load distribution, the user to access my native address again to jump to the background of the server, but I use load function to 403 after the mistake and can't enter the password with no response, the most important is the picture also shows that not all ~ teachers, please have a look at, what to do.
The following is the configuration




# the user nobody;
Worker_processes 1;

# error_log logs/error. The log;
# error_log logs/error log notice;
# error_log logs/error. The log info;

# pid logs/nginx. Pid;


Events {
Worker_connections 1024;
}
