nginx安装

阿里云cetos7已经默认添加了nginx的yum源，可以通过yum search nginx确认。

如果没有，则可以通过运行rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm进行添加。

命令

1

3
 systemctl start nginx.service # 启动nginx服务
 systemctl stop nginx.service # 关闭
 systemctl enable nginx.service # 开机

配置

由于我开启了8001的安全组规则，所以我使用8001端口来演示展示一个Hello Nginx页面

由于是使用yum安装的，所以让我们看看nginx安装到了哪?

1
 whereis nginx # nginx: /usr/sbin/nginx /usr/lib64/nginx /etc/nginx /usr/share/nginx /usr/share/man/man8/nginx.8.gz /usr/share/man/man3/nginx.3pm.gz

然后我发现/etc/nginx下面有配置文件nginx.conf，应该就是它了, 让我们看下文件内容cat nginx.conf

让我们增加一个server配置, 页面在~/nginx-demo/index.html:

server {
    listen       8001;
    listen       [::]:8001;
    server_name  _;
    root         ~/nginx-demo;

    # Load configuration files for the default server block.
    include /etc/nginx/default.d/*.conf;

    location / {
    }

    error_page 404 /404.html;
        location = /40x.html {
    }

    error_page 500 502 503 504 /50x.html;
        location = /50x.html {
    }
}

让我们打开浏览器访问页面看看.

发现页面403，让我们看看怎么了？ 发现是我们所在的文件夹没有读取权限，通过运行chmod 755 /root即可(/root就是~)。

这样我们就可以访问页面了。??
