Nginx网站服务详解（设置并发数、实现不同虚拟主机等）

一、nginx的最大并发数设置已经状态收集模块

[root@192 nginx]# cat nginx.conf
# For more information on configuration, see:

#   * Official Russian Documentation: http://nginx.org/ru/docs/user nginx;
worker_processes auto;
worker_cpu_affinity 0001 0010 0100 1000;

include /usr/share/nginx/modules/*.conf;events {use epoll;worker_connections 20480;
}http {log_format  main  '$remote_addr - $remote_user [$time_local] "$request" ''$status $body_bytes_sent "$http_referer" ''"$http_user_agent" "$http_x_forwarded_for"';access_log  /var/log/nginx/access.log  main;sendfile            on;tcp_nopush          on;tcp_nodelay         on;keepalive_timeout   65;types_hash_max_size 4096;include             /etc/nginx/mime.types;default_type        application/octet-stream;# Load modular configuration files from the /etc/nginx/conf.d directory.# See http://nginx.org/en/docs/ngx_core_module.html#include# for more information.include /etc/nginx/conf.d/*.conf;server {listen       80;listen       [::]:80;server_name  _;root         /usr/share/nginx/html;# Load configuration files for the default server block.include /etc/nginx/default.d/*.conf;

#        # Load configuration files for the default server block.
#        include /etc/nginx/default.d/*.conf;
#
#        error_page 404 /404.html;
#            location = /40x.html {
#        }
#
#        error_page 500 502 503 504 /50x.html;
#            location = /50x.html {
#        }
#    }}[root@192 nginx]#

验证

二、nginx的用户身份验证

server{
....
location /nginx_status {
stub_status on;
access_log off;
auth_basic "username and password";
auth_basic_user_file /usr/local/nginx/userlist.db;
}
}
