I thought about project Light for a long time and felt ready to start. The first beam of light enters the server:
Servers are to hobbyists what swords are to men
About Linux cloud server to get started, the pit to walk you through. Remember one thing: a server is an always-on, screen-less notebook, a brick remover who never sees the light of day.
Chapter one: Entering the arena
1. Blood
How do you know if something is yours? Yes, it’s a password. So that your artifact is yours alone:
2. Who am I, where am I, and where am I going
Click Login to enter the server
Then speak the first of the three questions of the soul: Who am I?
And then uttered the three questions of the soul: Where am I?
And then the end of the soul’s three questions: Where am I going?
This problem is too difficult, the server says I don’t know.
3. A sword in a scabbard fits a hero
It’s a hassle to use a browser every time you log in, and there’s a lot of terminal connectivity software, like SecureCRT
Downloading stuff, a bunch of them. Click quick Connect in the upper right corner and fill in the host name with your public IP address (IP is the red area in the first image)
Then you’ll be asked to enter your password. Just type it in.
[root@VM_0_4_centos ~]# centos Linux release 7.6.1810 (Core)Copy the code4. If you want to be rich, build roads
Now the server is a small village with only a steel cable bridge, the first FTP run through, at least can send and receive server files
In the console security group first put the common port open 22,80,21,3306, etc.
[root@VM_0_4_centos ~]# systemctl status firewalld.service # check firewall information ● firewalld.service - firewalld-dynamic firewall daemon Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; Vendor preset: enabled) Active: Inactive (dead) # indicates that the default is turned off Docs: Man: firewalld (1)/root @ VM_0_4_centos ~ # RPM - qa | grep VSFTPD # check whether installed VSFTPD/root @ VM_0_4_centos ~ # yum - y install [root@VM_0_4_centos ~]# systemctl start VSFTPDCopy the codeThe default FTP file is under /var/ftp. Now you can access and download the server file through a browser.
[root@VM_0_4_centos ~]# cd /var/ftp
[root@VM_0_4_centos ftp]# mkdir projects
[root@VM_0_4_centos ftp]# ls
projects pub
Copy the code
Here you can use FileZilla to transfer files:
Elder brother is the supreme root Permission, what qualifications do you have denied me?
By default, VSFTPD does not expose FTP for root user. You can change this or create a new user.
Run the following command to restart vsftpd.service: vi /etc/vsftp/ftpusers root vi /etc/vsftp/user_listCopy the code
A song I really like the MV and also audio-visual material: ftp://175.24.44.231/projects/
In this way, the two ends of the road, file interoperability.
Chapter 2: Battle of the Sword (Java)
1. The best sword in the world -Java
Have a look, how can endure without Java, sword out of scabbard, call Java.
[root@VM_0_4_centos local]# java --version
-bash: java: command not found
Copy the code--[· yum search JDK # search JDK ---->[result]-----/ / a little...
java-1.8. 0-openjdk.x86_64 : OpenJDK Runtime Environment
/ / a little...
---[· yum install java-1.8. 0# install JDL --[· Java -version openJDK version"1.8.0 comes with _232"
OpenJDK Runtime Environment (build 1.8. 0 _232-b09)
OpenJDK 64-Bit Server VM (build 25.232-b09, mixed mode)
Copy the code2. The most gorgeous aura of Java Sword –SpringBoot
Now run the SpringBoot project, first to demonstrate, see the SpringBoot series (has been placed in FTP, can download)
Upload the locally written project to the server via FTP and run it using java-JAR
[root@VM_0_4_centos ~]# cd ~
[root@VM_0_4_centos ~]# mkdir project
[root@VM_0_4_centos ~]# ls
project
Copy the code
The server is open and can now be accessed :http://175.24.44.231/
At this point, you can test the server to see if it’s working properly, that it’s connected, and that’s the foundation of everything
3. In the name of the universe – domain name
A domain name maps your server’S IP address to www.toly1994.com. What’s the big deal
Do not need domain name, to others throw an IP also can visit, but with the domain name + put on record is justified, we are good citizens.
It is easy to resolve the domain name and map it to a public IP address
So toly1994.com begins to wake up,
Small broken village for the server to repair the road, and built a small broken room, so far, domain name resolution OK.
4. Your life is protected by me – the firewall
Systemctl start firewald. service # Enable firewall systemctl stop firewald. service # disable firewall systemctl status firewald. service # Checking the Firewall StatusCopy the codeOnce the firewall is enabled, access to toly1994.com will not find port 80, you need to open the firewall port
[root@VM_0_4_centos ~]# /sbin/iptables -l -n # Check ports opened by the firewall Chain INPUT (Policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destinationCopy the codeFirewall-cmd --permanent --add-port=80/ TCP # open port 80 firewall-cmd --reload # restart firewallCopy the codeWhen you need to open a port, just open it yourself. There’s a catch: the application dies when you close the command line
You can use sudo nohup Java -jar n_stack-0.0.1 -snapshot.jar to enable this function
The Java/SpringBoot army is assembled and ready to attack…
Chapter 3: Multimedia – Nginx/Streaming media Server
1. Create a folder
- [CD/usr/local / - [· mkdir nginx - [CD nginx /Copy the code2. Download and decompress nginx and nginx-rtmp-module

Port 80 is already in use. You can change port 8080 in conf/nginx.conf
---[· cd conf
---[· ls
fastcgi.conf fastcgi_params koi-utf mime.types nginx.conf scgi_params uwsgi_params win-utf
fastcgi.conf.default fastcgi_params.default koi-win mime.types.default nginx.conf.default scgi_params.default uwsgi_params.default
---[· vim nginx.conf
Copy the code
5. Start the nginx
There’s nothing out of the console. Don’t panic. If there’s nothing wrong, it’s a success, okay
Note: Tencent cloud console security group and firewall need to open port 8080
- [CD/usr/local/nginx/sbin - [·. / nginx - [, ps - ef | grep nginx at 10:32 root 10043 1 0 # to check the problem? 00:00:00 nginx: master process ./nginx nobody 10044 10043 0 10:32 ? 00:00:00 nginx: worker process root 14035 30742 0 11:03 pts/2 00:00:00 grep --color=auto nginxCopy the codeCD /usr/local/nginx/sbin. /nginx -s stop Disable./nginx -s reload restartCopy the code6.

Remember there’s a video in FTP

So any video under projects can be played on demand, and as for FFmpeg live, pray that the King lives longer…..

For the record, I’m not advertising Tencent cloud, just using it. You can use any virtual server
Even the Linux virtual machine on the computer can also simulate play, through the LAN can access if there is a public IP, can make their own computer into a high-performance server….
