• 开机启动
  • chmod 755 /etc//init.d/nginx
  • chkconfig --add nginx
  • chkconfig nginx on
• nginx的配置文件

  [root@aminglinux-02 conf]# mv nginx.conf nginx.conf.bak
  [root@aminglinux-02 conf]# vim nginx.conf

• 检测配置文件/usr/local/nginx/sbin/nginx -t
• 重新加载配置文件/usr/local/nginx/sbin/nginx -s reload
• 测试
  • curl localhost
• 测试php解析

  [root@aminglinux-02 ~]# vim /usr/local/nginx/html/2.php
  <?php
  echo "test php scripts.";
  ?>
  [root@aminglinux-02 ~]# curl localhost/2.php
  test php scripts.

  nginx的默认虚拟主机

• 在/usr/local/nginx/conf/nginx.conf的http服务里面增加一行 include vhosts/*.conf;
• mkdir /usr/local/nginx/conf/vhost
• vim /usr/local/nginx/conf/default.conf

  server
  {
  listen 80 default_server;
  server_name aaa.com
  index index.html index.htm index.php;
  root /data/wwwroot/default;
  }

• mkdir -p /data/wwwroot/default
• 创建测试页

  [root@aminglinux-02 vhosts]# vim /data/wwwroot/default/index.html
  this is a default site.

• /usr/local/nginx/sbin/nginx -t
• /usr/local/nginx/sbin/nginx -s reload
• 测试

  [root@aminglinux-02 vhosts]# curl localhost
  this is a default site.
  [root@aminglinux-02 vhosts]# curl -x 127.0.0.1:80 aaa.com
  this is a default site.
  [root@aminglinux-02 vhosts]# curl -x 127.0.0.1:80 bbb.com
  this is a default site.

  nginx的用户认证

• vim /usr/local/nginx/conf/vhosts/test.com.conf

  server
  {
  listen 80;
  server_name test.com;
  index index.html index.htm index.php;
  root /data/wwwroot/test.com;
  
  location /   #/针对整个网站，/admin针对admin目录，~admin.php针对一个页面
  {
    auth_basic     "Auth"  #指定用户名
    auth_basic_user_file  /usr/local/nginx/conf/htpasswd; #指定密码文件
  }
  }

• yum install -y httpd 安装apche

  Downloading packages:

  这个错误需要手动安装不能安装的包，从下网上一个个安装

• 生产密码文件

  [root@aminglinux-02 ~]# htpasswd -c /usr/local/nginx/conf/htpasswd aming
  New password:
  Re-type new password:
  Adding password for user aming
  [root@aminglinux-02 ~]# cat /usr/local/nginx/conf/htpasswd

• 重新加载配置文件

  [root@aminglinux-02 ~]# /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@aminglinux-02 ~]# /usr/local/nginx/sbin/nginx -s reload

• 测试

  [root@aminglinux-02 ~]# curl -u aming:123456 -x127.0.0.1:80 test.com
  test.com

  域名重定向

• 更改test.com.conf

  server
  {
  listen 80;
  server_name test.com test1.com test2.com; #指定多个域名，httpd不一样
  index index.html index.htm index.php;
  root /data/wwwroot/test.com;
  if ($host != ‘test.com‘) {
   rewrite  ^/(.*)$ http://test.com/$1 permanent; #permanent是301，redirect是3
  02
  }
  }

• 加载配置

  [root@aminglinux-02 ~]# /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@aminglinux-02 ~]# /usr/local/nginx/sbin/nginx -s reload
