# 1. Please modify time of Ubuntu OS,Update installing application resource for Linux.

timedatectl set-timezone Asia/Shanghai
apt update
apt upgrade

# 2. install libraries about QT and ffmpeg

apt-get install qt5-default
apt install libavutil55
apt install libavcodec57
apt install libavformat57
apt install libswresample2
apt install libswscale4
apt install libqt5multimedia5
apt install libqt5multimedia5-plugins

# 3. install FFMPEG

1. 上传ffmpeg压缩包到服务器 upload the ffmpeg file to server
把ftp上的ffmpeg.zip(目录:/wjf/ffmpeg.zip)上传到/opt目录下 and upload this file ffmpeg.zip to this directory /opt
unzip ffmpeg.zip

2. 安装依赖 install related dependency
sudo apt-get -y install autoconf automake build-essential libass-dev libfreetype6-dev libsdl2-dev libtheora-dev libtool libva-dev libvdpau-dev libvorbis-dev libxcb1-dev libxcb-shm0-dev libxcb-xfixes0-dev pkg-config texinfo zlib1g-dev

3.汇编库 assembly library
Yasm是一个完全重写的NASM(The Netwide Assembler)汇编;NASM是一个为可移植性与模块化而设计的一个80x86的汇编器。它支持相当多的目标文件格式,包括Linux,*BSD,a.out,ELF,COFF,Mach−O,Microsoft 16−bit OBJ,Win32以及Win64,同时也支持简单的二进制文件生成。它的语法被设计的简单易懂,相较Intel的语法更为简单,支持目前已知的所有x86架构之上的扩展语法,同时也拥有对宏命令的良好支持。

sudo apt-get install yasm
sudo apt-get install nasm

4.视频库 video related library
要支持X264等视频处理,就需要安装相应的库:install libraries for X264 video processing
sudo apt-get install libx264-dev
sudo apt-get install libx265-dev

5.音频库 audio related library
要支持常见的音频处理,需要安装:install libraries for audio processing
sudo apt-get install libfdk-aac-dev
sudo apt-get install libmp3lame-dev
sudo apt-get install libopus-dev
sudo apt install libssl-dev libssl-doc

6.更新openssl版本(此步骤通常用于openssl版本不是1.1.1的情况下) update the version of openssl(if the version number is not 1.1.1)
执行openssl -version 为1.1.1,如果是1.1.0则需要手动下载openssl进行编译安装(check the version number,if version number is 1.1.0 then download openssl and install it)

7.配置ffmpeg并安装 configurate ffmpeg and install it
cd /opt/ffmpeg/ffmpeg-4.3.2
./configure --prefix=/opt/ffmpeg --enable-libx264 --disable-yasm --enable-nonfree --enable-libfdk-aac --enable-shared --enable-gpl --enable-libmp3lame --enable-libopus --extra-cflags=-I/usr/local/include --extra-ldflags=-L/usr/local/lib --enable-openssl
make install

8.库配置和路径配置libraries configuration and path configuration
配置库所在路径,以便FFmpeg能加载相应库。打开配置文件 config libraries path for using ffmpeg anywhere.
sudo vi /etc/ld.so.conf
在文件末尾加上:attach this command at end of file
然后执行sudo ldconfig,重新加载配置以生效。then excute sudo Idconfig,and re-load configuration

9.路径配置 path configuration 
为能随时使用FFmpeg,需要把对应目录添加到路径中。add the directory to path configuration for using ffmpeg anywhere.
vi ~/.bashrc
在文件末尾加上:attach this command at end of file:
excute source ~/.bashrc

# 4. install MySql

apt-get update
apt-get install mysql-server
#初始化配置(参考下面的选项) inital configuration(please reference to following configuration)

VALIDATE PASSWORD PLUGIN can be used to test passwords...
Press y|Y for Yes, any other key for No: N (My selection)

Please set the password for root here...
New password: (input password)
Re-enter new password: (re-enter password)

By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them...
Remove anonymous users? (Press y|Y for Yes, any other key for No) : N (My selection)

Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network...
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : Y (My selection)

By default, MySQL comes with a database named 'test' that
anyone can access...
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : N (My selection)

Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y (My selection)

#设置mysql登陆时候需要密码 config password of mysql
> use mysql;
> update user set authentication_string=password("your password") where user='root';  #(无password字段的版本,也就是版本<=5.7的 there is no password field when version<=5.7)
> update user set password=password('your password') where user='root'; #(有password字段的版本,版本>5.7的 there is password field when version>5.7)
> update user set plugin="mysql_native_password"; 
> flush privileges;
> exit;

#检查mysql服务状态 check service status of mysql
systemctl status mysql.service
#创建云剪和直播剪数据库 create databse of Meishe-Editor and Meishe-LiveEditor
drop database if EXISTS livebsedit;
create database livebsedit CHARACTER SET utf8 COLLATE utf8_general_ci;

# 5.Install nginx,please conference to this link https://blog.csdn.net/qq_23832313/article/details/83578836 (opens new window)

# 6. Deploy Meishe-LiveEditor services

1.直播剪包livebsedit,配置文件config.yaml,转码器三个文件放到/opt/livebsedit目录下 Meishe-LiveEditor  livebsedit,and configuration file is config.yaml,and put three files of transcoder to this directory /opt/livebsedit
cd /opt/livebsedit
chmod 755 NvTranscoder
chmod 755 livebsedit
nohup ./livebsedit &
查看日志tail -f latest_log    check logs
输出以下两行则表明服务启动成功  the service has start normally when there are result of two lines
router register success
websocket manage start
