Nginx安装、默认虚拟主机、Nginx用户认证、Nginx域名重定向

12.6 Nginx安装

  • 安装包下载到/usr/local/src目录
[root@taoyuan ~]# cd /usr/local/src
[root@taoyuan src]# wget http://nginx.org/download/nginx-1.12.1.tar.gz
  • 解压压缩包
[root@taoyuan src]# tar zxf nginx-1.12.1.tar.gz
[root@taoyuan src]# ls
nginx-1.12.1
  • 编译Nginx
[root@taoyuan nginx-1.12.1]# ./configure --prefix=/usr/local/nginx
#在此编译过程中没有加相关的参数
#需要根据需求加相关的模块

[root@taoyuan nginx-1.12.1]# make && make install
#在安装之后尽量保留源码包
  • 配置Nginx
#配置文件
[root@taoyuan nginx-1.12.1]# ls /usr/local/nginx/conf/
fastcgi.conf            koi-utf             nginx.conf           uwsgi_params
fastcgi.conf.default    koi-win             nginx.conf.default   uwsgi_params.default
fastcgi_params          mime.types          scgi_params          win-utf
fastcgi_params.default  mime.types.default  scgi_params.default

#样例模板
[root@taoyuan nginx-1.12.1]# ls /usr/local/nginx/html/
50x.html  index.html #样例

#存放日志
[root@taoyuan nginx-1.12.1]# ls /usr/local/nginx/logs/

#Nginx进程
[root@taoyuan nginx-1.12.1]# ls /usr/local/nginx/sbin/
nginx
#支持参数 
# -t 查看配置文件是否有错
  • 配置启动脚本
[root@taoyuan nginx-1.12.1]# vim /etc/init.d/nginx

#nginx内容如下

[root@taoyuan nginx-1.12.1]# chkconfig --add nginx
[root@taoyuan nginx-1.12.1]# chkconfig nginx on
  • 配置文件
[root@taoyuan nginx-1.12.1]# cd /usr/local/nginx/conf/
[root@taoyuan conf]# ls

[root@taoyuan 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
  • 启动服务
[root@taoyuan conf]# /etc/init.d/nginx start
Starting nginx (via systemctl):                            [  确定  ]
[root@taoyuan conf]# ps aux |grep nginx

  • 测试
  • 测试解析PHP
[root@taoyuan conf]# vim /usr/local/nginx/html/1.php
[root@taoyuan conf]# curl localhost/1.php
Hello Nginx ![root@taoyuan conf]#

12.7 默认虚拟主机

#注释掉nginx.conf 中的server 

    include vhost/*.conf; #增加一行
    #server
    #{
     #   listen 80;
     #   server_name localhost;
     #   index index.html index.htm index.php;
     #   root /usr/local/nginx/html;
     #   location ~ \.php$
     #   {
     #       include fastcgi_params;
     #       fastcgi_pass unix:/tmp/php-fcgi.sock;
     #       fastcgi_index index.php;
     #       fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
     #   }
    #}
  • 创建vhost目录和配置文件
[root@taoyuan conf]# mkdir vhost
[root@taoyuan conf]# vim vhost/aaa.com.conf


#配置文件内容
server
{
   listen 80 default_server;   #有这个标记的就是默认虚拟主机
   server_name aaa.com;
   index index.html index.htm index.php;
   root /data/wwwroot/default;
}
  • 创建/data/wwwroot/default
[root@taoyuan vhost]# mkdir -p /data/wwwroot/default
#如果有可以不用创建
  • 检测
#检测错误
[root@taoyuan 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

#重启服务
[root@taoyuan default]# /etc/init.d/nginx restart

#重新加载
[root@taoyuan default]# /usr/local/nginx/sbin/nginx -s reload

#测试结果
[root@taoyuan default]# curl localhost
Hello default . #默认虚拟主机
#它的域名也是跳转到默认虚拟主机
[root@taoyuan default]# curl -x127.0.0.1:80 bbb.com
Hello default .

12.8 Nginx用户认证

  • 创建一个test.com.conf 文件
[root@taoyuan default]# vim /usr/local/nginx/conf/vhost/test.com.conf


#内容
server
{
   listen 80;                  
   server_name test.com;
   index index.html index.htm index.php;
   root /data/wwwroot/test.com;

   location /
     {
       auth_basic         "Auth";
       auth_basic_user_file /usr/local/nginx/conf/htpasswd;
     }
}
  • 创建密码文件
#可以用Apache htpasswd工具生成
[root@taoyuan vhost]# /usr/local/apache2.4/bin/htpasswd

#没有安装可以yum安装一个
[root@taoyuan vhost]# yum install -y httpd

#生成文件 如果继续添加 不用带 -c选项
[root@taoyuan vhost]# htpasswd -c /usr/local/nginx/conf/htpasswd taoyuan
New password: 
Re-type new password: 
Adding password for user taoyuan

#htpasswd 文件内容
[root@taoyuan vhost]# cat /usr/local/nginx/conf/htpasswd 
taoyuan:$apr1$O4dujhQC$5XXU.vdIxoQFBeHKGWjOZ1
user:$apr1$RiNQMrIS$7RUcVzpXr3uJ5mvioNtHj/
  • 测试配置并重新加载
[root@taoyuan vhost]# /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@taoyuan vhost]# /usr/local/nginx/sbin/nginx -s reload
#重新加载,不会加载配置文件中的错误。
#如果重启服务,配置文件中出现错误,将导致服务起不了。

#测试
[root@taoyuan vhost]# curl -x127.0.0.1:80 test.com -I
HTTP/1.1 401 Unauthorized
Server: nginx/1.12.1
Date: Wed, 03 Jan 2018 13:57:48 GMT
Content-Type: text/html
Content-Length: 195
Connection: keep-alive
WWW-Authenticate: Basic realm="Auth"

[root@taoyuan vhost]# mkdir /data/wwwroot/test.com
[root@taoyuan vhost]# echo "test.com" > /data/wwwroot/test.com/index.html
[root@taoyuan vhost]# curl -u taoyuan:taoyuan -x127.0.0.1:80 test.com
test.com
  • 指定目录来访问控制 当需站点需要访问某个目录才进行访问控制,只需要在 location /admin/ 增加一个目录

  • 测试
[root@taoyuan vhost]# /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@taoyuan vhost]# /usr/local/nginx/sbin/nginx -s reload

[root@taoyuan vhost]# curl -x127.0.0.1:80 test.com
test.com
[root@taoyuan vhost]# mkdir /data/wwwroot/test.com/admin
[root@taoyuan vhost]# echo "test.com admin dir" > /data/wwwroot/test.com/admin/index.html

#curl测试
[root@taoyuan 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/1.12.1</center>
</body>
</html>
[root@taoyuan vhost]# curl -utaoyuan:taoyuan -x127.0.0.1:80 test.com/admin/
test.com admin dir
  • 指定一个文件访问控制

通过匹配 admin.php文件来访问控制

  • 测试
[root@taoyuan vhost]# /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@taoyuan vhost]# /usr/local/nginx/sbin/nginx -s reload

[root@taoyuan vhost]# echo ' <?php echo "test.com/damin.php"; ?> ' > /data/wwwroot/test.com/admin.php

[root@taoyuan vhost]# curl -x127.0.0.1:80 test.com/admin/
test.com admin dir

[root@taoyuan 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/1.12.1</center>
</body>
</html>

[root@taoyuan vhost]# curl -utaoyuan:taoyuan -x127.0.0.1:80 test.com/admin.php
 <?php echo "test.com/damin.php"; ?> 
#由于没有配置PHP解析所以无法解析php,访问控制是成功的。

12.9 Nginx域名重定向

[root@taoyuan vhost]# vim /usr/local/nginx/conf/vhost/test.com.conf 

#配置文件编辑内容
server
{
   listen 80;
   server_name test.com test2.com test3.com; #可以跟多个域名
   index index.html index.htm index.php;
   root /data/wwwroot/test.com;
   #需要增加if语句进行判断
	 if ($host != 'test.com'){
       rewrite ^/(.*)$ http://test.com/$1 permanent; #简写
			 #写全为 rewrite http://$host/(.*)$ http://test.com/$1 permanent;
   }

}
  • 检测
