One: When you use to build Nginx virtual host server, each virtual WEB site has a separate "server {}" configuration section, each listening IP address and port number can be specified individually, of course, the site name is different.
Two: the virtual machine category:
1: name-based virtual hosts (ip address of a domain name corresponding to a plurality of different domain is a different site, its content is not the same)
2: Port-based virtual host (server has only one ip address, different port is a different site, its content is not the same)
3: ip-based virtual host (server has multiple ip addresses, different ip is a different site, its content is not the same)
Two: nginx -t used to detect configuration file syntax
1 following error: error profile line 43
[root@www ~]# nginx -t
nginx: [emerg] "location" directive is not allowed here in /usr/local/nginx/conf/nginx.conf:43
nginx: configuration file /usr/local/nginx/conf/nginx.conf test failed
The following error 2: worker inside the work area problems
[root@www ~]# nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: [warn] 10240 worker_connections exceed open file resource limit: 1024
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
Solution:
[root@www ~]# ulimit -n 10240
