6.vim /etc/init.d/nginx //编写启动脚本写入以下配置 并把权限改为755 设置开机启动：chkconfig --add nginx chkconfig /on

7. /usr/local/nginx/sbin/nginx -t //检查语法（提示success就没问题）

8./etc/init.d/nginx start  //开启服务

9. ps aux |grep nginx //检查服务

10.测试能否解析php：

        curl /usr/local/nginx/html/1.php

默认虚拟主机 12.8 

1.修改主机配置文件：添加以下一行

include vhost/*.conf   //意思是/usr/local/nginx/conf/vhost/下面所以以.conf结尾的文件都会被加载

2.在conf目录下创建vhost目录并写一个.conf配置文件

mkdir vhost 

vim /vhost/default.conf

3.在default.conf配置文件写入以下内容

server
{
listen 80 default_server;   //default标记默认虚拟主机
server_name aaa.com;      //域名
index index.html index.htm index.php;   //支持的解析
root /data/nginx;    //访问那个页面

}

4.检查语法

    /usr/local/nginx/sbin/nginx -t

5.创建data和nginx目录

mkdir data 

mkdir nginx

6.在nginx目录写入一个html

vim index.html 

            this is a test!

7.重新加载配置文件

    /usr/local/nginx/sbin/nginx -s reload

8。测试

curl localhost 

Nginx用户认证

1.创建多一个虚拟主机配置

    vim /usr/local/nginx/conf/vhost/test.conf

添加如下配置：

•             server
  {
  listen 80;
  server_name test.com;   
  index index.html index.html index.php;
  root /data/nginx1;
  
  location /                             //指定要做用户认证目录、文件、html
  {
  auth_basic  "Auth";    //打开认证
  auth_basic_user_file /usr/local/nginx/conf/vhost/htpasswd;   //指定密码文件
  }
  }
• /usr/local/nginx/sbin/nginx -t 检查语法 
• yum install -y httpd   //安装httpd，因为要借用httpd生成密码文件
• find  /  -name htpasswd  //查找htpasswd工具在哪
• /usr/bin/htpasswd   //一般yum安装得再这里
• /usr/bin/htpasswd -c /usr/local/nginx/conf/vhost/htpasswd test  // 生成密码文件，输入密码
• mkdir nginx1  创建站点目录
• cd  nginx1                                    echo “this is  test”> index.html  //写入内容
• /usr/local/nginx/sbin/nginx -s reload  //重新加载配置文件
• curl -x127.0.0.1:80 test.com  -utest:test    //测试   -u 输入账号密码
• 
  

Nginx域名重定向

类似httpd的域名跳转

在原先用户认证上添加配置：如下

• server
  {
  listen 80;
  server_name test.com test1.com test2.com ;
  index index.html index.html index.php;
  root /data/nginx1;
  
  
  if ($host != 'test.com' ){      //如果host不等于则rewrite
  rewrite ^/(.*)$ http://test.com/$1 permanent;   // ^任意开头(比如httpd：//）  （.*）通配  $到结尾
  }
  
  }
  
• permanent 表示永久重定向 （301）  redirect临时重定向（302)
• /usr/local/nginx/sbin/nginx  -t  
  
• /usr/local/nginx/sbin/nginx  -s reload
  
• curl -I -x127.0.0.1:80 test1.com  //测试下图可以看到location跳转到 test.com
  
•
