12.6 Nginx安装

安装过程

# cd /usr/local/src

# wget http://nginx.org/download/nginx-1.14.0.tar.gz （一般来说，偶数版本为稳定版，适合生产环境）

# tar xzf nginx-1.14.0.tar.gz

# cd nginx-1.14.0/

# ./configure --prefix=/usr/local/nginx

# make && make install

设置过程

# cd /usr/local/nginx/conf/

# mv nginx.conf nginx.conf1 //把系统自带的配置文件改名备份

# vim nginx.conf //创建新的配置文件，写入以下内容,参考链接

# chmod 755 /etc/init.d/nginx

#/etc/init.d/nginx start

# ps aux |grep nginx

测试

# curl localhost

6月7日任务

#vim /usr/local/nginx/html/1.php //创建一个php文件，简单写入以下内容

6月7日任务

# curl localhost/1.php //可以正常解析php

12.7 Nginx默认虚拟主机

# vim /usr/local/nginx/conf/nginx.conf //编辑配置文件，删除最后几行并添加一行内容

6月7日任务

# mkdir /usr/local/nginx/conf/vhost

#cd /usr/local/nginx/conf/vhost

# vim aaa.com.conf //新建并添加如下内容

server
{
    listen 80 default_server;   //有这个标记就是默认虚拟主机
    server_name aaa.com;
    index index.html index.htm index.php;
    root /data/wwwroot/default;
}

6月7日任务

# mkdir -p /data/wwwroot/default

# echo “This is a default site.”>/data/wwwroot/default/index.html

# /usr/local/nginx/sbin/nginx -t //检查语法

6月7日任务

# /usr/local/nginx/sbin/nginx -s reload //重新加载

测试

# curl localhost

6月7日任务

下面说一下总结默认虚拟主机的两种方法

1.在/usr/local/nginx/conf/vhost目录下排在第一位，比如下面aaa.com.conf就是默认的虚拟主机

2.改配置文件

12.8 Nginx用户认证

#vim /usr/local/nginx/conf/vhost/test.com.conf //写入如下内容

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;
}
}
