Linux environment nginx to build a simple picture server

Nginx and vsftpd are mainly used.
The installation can be downloaded directly from the nginx website, or...

yum install nginx  

If you don't have an yum source, you need to add it yourself and then install.

yum install wget

wget http://www.atomicorp.com/installers/atomic  

sh ./atomic  

yum check update  

If you download it from the official website, do the following:

[root@admin local]# cd /usr/local

[root@admin local]# tar -zxv -f nginx-1.6.2.tar.gz

[root@admin local]# rm -rf nginx-1.6.2.tar.gz

[root@admin local]# mv nginx-1.6.2 nginx

[root@admin local]# cd /usr/local/nginx

[root@admin nginx]# ./configure --prefix=/usr/local/nginx

[root@admin nginx]# make

[root@admin nginx]# make install   　  

Install vsftpd:

yum install vsftpd  

The nginx configuration is not too complicated, only a virtual directory is created and directory browsing is enabled.
When I want to access http://localhost/apps, the actual access path is /home/appmanager/
First I need to create an apps folder under nginx/html, even though I'm not actually accessing this path.

mkdir /usr/local/nginx/html/apps

Then modify nginx/conf/nginx conf in default server add 1 location and specify the actual path:

    location /apps/ {

        root /home/appmanager/;

        #alias ;

        autoindex on;

        #autoindex_exact_size off;

        #autoindex_localtime on;

    }  

autoindex on is for browsing.
root maps apps to /home/appmanager/apps/
Of course, alias does what I want, but it's a little different.

You then need to create the user, which is appmanager in the configuration file above.

useradd -d /home/appmanager -M appmanager

Then specify the directory and add permissions

chown appmanager /home/appmanager

chmod 777 -R /home/appmanager

For some reason, the first time I created the user's directory, it never took effect, although repeated usermod-d also had no effect...

However, it is now accessible via Jsch api.

public static void main(String[] args) throws JSchException {

    Session session = null;

    ChannelSftp channelSftp = null;

    try {

        JSch.setLogger(new JSCHLogger());

        JSch jsch = new JSch();

        session = jsch.getSession("appmanager", "101.x.x.x", "22");

        session.setPassword("password");
        Properties config = new Properties();

        config.put("StrictHostKeyChecking", "no");

        session.setConfig(config);

        session.connect();
        channelSftp = (ChannelSftp) session.openChannel("sftp");

        channelSftp.connect();
    } catch (JSchException | SftpException | IOException e) {

        logger.error(e.getMessage(), e);

    } finally {

        if (channelSftp != null) {

            channelSftp.disconnect();

        }

        if (session != null)

            session.disconnect();

    }

}
