rocky minum necessary for installation

安装依赖

yum -y install gcc automake autoconf libtool make
yum -y install pcre-devel openssl openssl-devel gd-devel gcc gcc-c++
yasm-1.3.0  安装
cd yasm-1.3.0
./configure
make && make install

安装ffmpeg

方法1
cd ffmpeg-xxx
./configure --prefix=/usr/local/ffmpeg
make && make install
ln /usr/local/ffmpeg/bin/ffmpeg /usr/bin/ffmpeg
ln /usr/local/ffmpeg/bin/ffprobe /usr/bin/ffprobe

方法2
sudo dnf install epel-release
sudo yum config-manager --set-enabled powertools
sudo yum config-manager --add-repo=https://negativo17.org/repos/epel-multimedia.repo
sudo dnf install ffmpeg

ffmpeg -version

nginx安装

http://nginx.org/download/   下载版本
GitHub - arut/nginx-rtmp-module: NGINX-based Media Streaming Server   rtmp模块下载
yum -y install openssl openssl-devel  #若没有安装依赖执行此步

./configure –prefix=/usr/local/nginx –add-module=/root/nginx-rtmp-module-master

make && make install
如果启动失败尝试下面命令
yum -y install compat-openssl10
# systemctl stop firewalld
# systemctl disable firewalld

配置帮助
https://nginx.org/en/docs/http/ngx_http_core_module.html#directives

跨域问题：
http中增加
add_header Access-Control-Allow-Origin *; 

安装python3

dnf -y update
dnf install python39
python3 --version

安装samba

yum install samba

配置
vi /etc/samba/smb.conf
[global]
workgroup = WORKGROUP
server string = Samba Server %v
netbios name = almaLinux-8
security = user
map to guest = bad user
dns proxy = no
ntlm auth = true
[opt]
path = /opt
browsable = yes
writable = yes
guest ok = yes
read only = no

启动和设置自启动
systemctl start smb
systemctl status smb
systemctl enable smb  

若samba启动了，但遇到权限问题，执行下面三步
sudo chmod -R 777 /opt
sudo chown -R nobody:nobody /opt
sudo chcon -t samba_share_t /opt

要关闭SELINUX : 很关键，不然也只能读不能写
setenforce 0  #临时关闭
# vi /etc/sysconfig/selinux   then reboot   永久关闭
SELINUX=permissive
# getenforce  #查看状态
Permissive #这个状态就可写了

 FTP服务器

安装
yum -y install vsftpd

配置，若不配置端口则默认端口如下，
• 20端口用于建立数据连接，并传输文件数据
• 21端口用于建立控制连接，并传输FTP控制命令
vi /etc/vsftpd/vsftpd.conf
pam_service_name=vsftpd
userlist_enable=NO
tcp_wrappers=YES
#ftp访问目录
local_root=/home/ftproot
#被动模式
pasv_enable=YES
#高端口
pasv_min_port=65000
pasv_max_port=65010

用户和文件权限
useradd ftpseven -s /sbin/nologin -d /home/ftproot
passwd ftpseven
chown -R ftpseven /home/ftproot
chmod 777 /home/ftproot
echo 'ftpseven' >> /etc/vsftpd/user_lis

若selinux被禁用
vim /etc/pam.d/vsftpd
注释掉如下内容
#auth required pam_shells.so

#防火墙设置
systemctl stop firewalld
firewall-cmd --permanent --zone=public --add-port=21/tcp
firewall-cmd --permanent --zone=public --add-port=65000-65010/tcp
firewall-cmd --reload #重新加载
firewall-cmd --zone=public --list-port #参考开发端口
#firewall-cmd --permanent --zone=public --remove-port=8886/tcp #禁用端口


#开机启动
systemctl enable vsftpd.service
#重启服务
systemctl restart  vsftpd.service 
#启动
systemctl start  vsftpd.service 
#停止
systemctl stop  vsftpd.service 
#状态
systemctl status  vsftpd.service

 设置sftp

vi /etc/ssh/sftpd_config
放开以下两个配置，并将其设置大一点
MaxSessions 200
MaxStartups 100:30:200

systemctl restart sshd
