user 定义上传等操作完成的用户
worker_processes 定义子进程的数量
error_log 错误日志
pid pid号
worker_rlimit_nofile 指定nginx最多打开多少文件
use epoll 使用epoll模式
worker_connections 进程最大的连接数
fastcgi_pass 如果监听端口是9000，可以写为127.0.0.1:9000这是两种不同方式
[root@localhost conf]# /usr/local/nginx/sbin/nginx -t nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful [root@localhost conf]# /etc/init.d/nginx start Starting nginx (via systemctl): [ 确定 ] [root@localhost conf]# ps aux |grep nginx root 9634 0.0 0.0 20496 628 ?

（上方有两个子进程 worker process，由配置文件中的worker_processes定义的）
[root@localhost conf]# curl localhost
（上方欢迎语由/usr/local/nginx/html/index.html，而为什么能访问到index.html由nginx.conf定义）
[root@localhost conf]# cd /usr/local/nginx/html/ [root@localhost html]# vim 1.php
[root@localhost html]# curl localhost/1.php This is nginx test page.[root@localhost html]#
12.7 默认虚拟主机
[root@localhost conf]# vim nginx.conf
删除以上内容，增加一行 include vhost/*.conf
[root@localhost conf]# mkdir vhost [root@localhost conf]# cd vhost/ [root@localhost vhost]# vim aaa.com.conf
（由default_server就证明这是默认虚拟主机）
[root@localhost vhost]# mkdir -p /data/wwwroot/default [root@localhost vhost]# cd !$ cd /data/wwwroot/default [root@localhost default]# vim index.html
[root@localhost default]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@localhost default]# /usr/local/nginx/sbin/nginx -s reload ##改配置文件后重新加载
[root@localhost vhost]# curl localhost
This is the default site.
(如果有错，请查看nginx.con、aaa.com.conf等配置是否有误)
指定默认虚拟主机：
1，vhost aaa 或者 0 等顺序
2，conf里指定default_server
12.8 Nginx用户认证
[root@localhost vhost]# vim test.com.conf
[root@localhost vhost]# /usr/local/nginx/sbin/nginx -s reload
·如果没有安装Apache，那么可以yum安装
[root@localhost vhost]# yum install -y httpd
·如果安装了Apache，那么可以直接使用htpasswd
[root@localhost vhost]# htpasswd -c /usr/local/nginx/conf/htpasswd alex New password: Re-type new password: Adding password for user alex [root@localhost vhost]# htpasswd /usr/local/nginx/conf/htpasswd arron New password: Re-type new password: Adding password for user arro [root@localhost vhost]# !cat cat /usr/local/nginx/conf/htpasswd alex:$apr1$MLMPfmsl$oH/QYxybIFQSNj4xLCh4S/ arron:$apr1$RfKhGXgJ$46dujc2WWwJDfWhhPn0311 （再创建第二个用户则不用 -c ） [root@localhost vhost]# curl -x127.0.0.1:80 test.com -I HTTP/1.1 401 Unauthorized Server: nginx/1.12.2 Date: Tue, 13 Mar 2018 15:25:28 GMT Content-Type: text/html Content-Length: 195 Connection: keep-alive WWW-Authenticate: Basic realm="Auth" [root@localhost vhost]# curl -u alex:123456 -x127.0.0.1:80 test.com <html> ##由于去访问的是index.html，而还未创建，所以404 <head><title>404 Not Found</title></head> <body bgcolor="white"> <center><h1>404 Not Found</h1></center> <hr><center>nginx/1.12.2</center> </body> </html>
·创建test.com主目录，并编辑index.html文件
[root@localhost vhost]# mkdir /data/wwwroot/test.com
[root@localhost vhost]# echo "test.com" > /data/wwwroot/test.com/index.html
[root@localhost vhost]# curl -u alex:123456 -x127.0.0.1:80 test.com
test.com
·如果需求为访问某个目录才需要认证，那么可以改配置文件
[root@localhost vhost]# /usr/local/nginx/sbin/nginx -s reload [root@localhost vhost]# curl -x127.0.0.1:80 test.com test.com [root@localhost vhost]# curl -x127.0.0.1:80 test.com/admin/ <html> <head><title>401 Authorization Required</title></head> <body bgcolor="white"> <center><h1>401 Authorization Required</h1></center> <hr><center>nginx/1.12.2</center> </body> </html> ##此时访问test.com是不需要认证，而在访问admin目录是则被限制 [root@localhost vhost]# vim /data/wwwroot/test.com/admin/ [root@localhost vhost]# mkdir !$ mkdir /data/wwwroot/test.com/admin/ [root@localhost vhost]# echo "test.com admin dir" > /data/wwwroot/test.com/admin/index.html [root@localhost vhost]# curl -ualex:123456 -x127.0.0.1:80 test.com/admin/ test.com admin dir
·针对url限制，例如admin.php，那么可以配置文件定义匹配：
[root@localhost vhost]# /usr/local/nginx/sbin/nginx -s reload [root@localhost vhost]# curl -x127.0.0.1:80 test.com/admin/ test.com admin dir [root@localhost vhost]# curl -x127.0.0.1:80 test.com/admin.php <html> <head><title>401 Authorization Required</title></head> <body bgcolor="white"> <center><h1>401 Authorization Required</h1></center> <hr><center>nginx/1.12.2</center> </body> </html>
（匹配admin.php后，/admin/不做限制，只针对admin.php进行限制）
·
创建admin.php才能访问到，不创建则会有404错误
[root@localhost vhost]# vim /data/wwwroot/test.com/admin.php
[root@localhost vhost]# /usr/local/nginx/sbin/nginx -s reload
[root@localhost vhost]# curl -ualex:123456 -x127.0.0.1:80 test.com/admin.php
test test test
12.9 Nginx域名重定向
[root@localhost vhost]# vim test.com.conf
（如果不是test.com,那么重定向到test.com下，permanent是301）
[root@localhost vhost]# curl -x127.0.0.1:80 test2.com/index.html -I
[root@localhost vhost]# curl -x127.0.0.1:80 test2.com/admin/index.html -I
[root@localhost vhost]# curl -x127.0.0.1:80 test3.com/admin/index.html -I HTTP/1.1 404 Not Found Server: nginx/1.12.2 Date: Tue, 13 Mar 2018 16:02:00 GMT Content-Type: text/html Content-Length: 169 Connection: keep-alive [root@localhost vhost]# ls aaa.com.conf test.com.conf
（由于没有定义test3.com，此时他会去访问默认虚拟主机，第一个也就是aaa.com）
如有错误，欢迎指正，互相学习，共同进步！！！
