CentOS8下编译配置nginx+rtmp，搭建推流服务器

热度：58   发布时间：2023-12-05 23:57:50.0

一.环境

服务器操作系统：CentOS Linux release 8.2.2004 (Core)
nginx 版本: https://nginx.org/download/nginx-1.18.0.tar.gz
RMTP模块：https://github.com/arut/nginx-rtmp-module

测试主机:ArchLinux
推流工具:OBS-Studio
拉流工具:VLC

二.准备编译环境

1.安装依赖

也可以直接跳过，在下面配置和编译的时候提示缺什么再安装什么

sudo dnf install gcc make pcre pcre-devel openssl openssl-devel

2. 下载nginx-1.18.0和rtmp模块

#####个人习惯，弄个临时文件夹存放#####
mkdir tmp
cd tmp

wget https://nginx.org/download/nginx-1.18.0.tar.gz
tar -zxvf nginx-1.18.0.tar.gz 

git clone https://github.com/arut/nginx-rtmp-module

三.编译安装

1.配置

###注意nginx源码文件夹和rtmp模块源码文件夹在同一目录下#########
./configure --prefix=/usr/local/nginx  --add-module=../nginx-rtmp-module  --with-http_ssl_module

2.编译

make

执行make过程中会报如下错

	-o objs/addon/nginx-rtmp-module/ngx_rtmp_eval.o \../nginx-rtmp-module/ngx_rtmp_eval.c
../nginx-rtmp-module/ngx_rtmp_eval.c: 在函数‘ngx_rtmp_eval’中:
../nginx-rtmp-module/ngx_rtmp_eval.c:160:17: 错误：this statement may fall through [-Werror=implicit-fallthrough=]switch (c) {
    ^~~~~~
../nginx-rtmp-module/ngx_rtmp_eval.c:170:13: 附注：herecase ESCAPE:^~~~
cc1：所有的警告都被当作是错误
make[1]: *** [objs/Makefile:1349：objs/addon/nginx-rtmp-module/ngx_rtmp_eval.o] 错误 1
make[1]: 离开目录“/home/centos/tmp/nginx-1.18.0”
make: *** [Makefile:8：build] 错误 2

原因是Makefile里有Werror选项，语法要求严格，将所有警告当作错误处理啦
解决方法

###位于nginx源码目录下#####
nano objs/Makefile

打开后内容如下


CC =    cc
CFLAGS =  -pipe  -O -W -Wall -Wpointer-arith -Wno-unused-parameter -Werror  -g 
CPP =   cc -E
LINK =  $(CC)ALL_INCS = -I src/core \-I src/event \-I src/event/modules \-I src/os/unix \-I ../nginx-rtmp-module \-I objs \-I src/http \-I src/http/modules
##################################
#######后面内容生略################

将-Werror删除

CFLAGS =  -pipe  -O -W -Wall -Wpointer-arith -Wno-unused-parameter   -g

ctrl+x，然后输入y保存退出 后再执行make

3.安装

sudo make install

4.查看安装结果

 /usr/local/nginx/sbin/nginx -v

输出版本号为
nginx version: nginx/1.18.0
安装成功

四.配置nginx

1.设置nginx开机启动

(1)创建nginx服务文件

sudo nano /usr/lib/systemd/system/nginx.service

创建nginx服务文件,输入以下内容

[Unit]
Description=nginx - high performance web server
After=network.target remote-fs.target nss-lookup.target[Service]
Type=forking
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s stop[Install]
WantedBy=multi-user.target

(2)启用nginx服务

sudo systemctl start nginx 
sudo systemctl enable nginx

2.修改配置文件

这是安装完nginx后的默认配置文件

#user nobody;
worker_processes  1;#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;#pid logs/nginx.pid;events {
    worker_connections  1024;
}http {
    include       mime.types;default_type  application/octet-stream;#log_format main '$remote_addr - $remote_user [$time_local] "$request" '# '$status $body_bytes_sent "$http_referer" '# '"$http_user_agent" "$http_x_forwarded_for"';#access_log logs/access.log main;sendfile        on;#tcp_nopush on;#keepalive_timeout 0;keepalive_timeout  65;#gzip on;server {
    listen       80;server_name  localhost;#charset koi8-r;#access_log logs/host.access.log main;location / {
    root   html;index  index.html index.htm;}#error_page 404 /404.html;# redirect server error pages to the static page /50x.html#error_page   500 502 503 504  /50x.html;location = /50x.html {
    root   html;}# proxy the PHP scripts to Apache listening on 127.0.0.1:80##location ~ \.php$ {
    # proxy_pass http://127.0.0.1;#}# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000##location ~ \.php$ {
    # root html;# fastcgi_pass 127.0.0.1:9000;# fastcgi_index index.php;# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;# include fastcgi_params;#}# deny access to .htaccess files, if Apache's document root# concurs with nginx's one##location ~ /\.ht {
    # deny all;#}}# another virtual host using mix of IP-, name-, and port-based configuration##server {
    # listen 8000;# listen somename:8080;# server_name somename alias another.alias;# location / {
    # root html;# index index.html index.htm;# }#}# HTTPS server##server {
    # listen 443 ssl;# server_name localhost;# ssl_certificate cert.pem;# ssl_certificate_key cert.key;# ssl_session_cache shared:SSL:1m;# ssl_session_timeout 5m;# ssl_ciphers HIGH:!aNULL:!MD5;# ssl_prefer_server_ciphers on;# location / {
    # root html;# index index.html index.htm;# }#}}

执行

sudo nano /usr/local/nginx/conf/nginx.conf

修改配置文件
在配置文件头部加入


rtmp_auto_push on;rtmp {
    server {
    listen 1935;     application live {
    live on;hls on;hls_fragment 3s;hls_playlist_length 10s;hls_path /usr/local/nginx/html/hls;}}
}

修改后配置文件内容如下

rtmp_auto_push on;rtmp {
    server {
    listen 1935;application live {
    live on;hls on;hls_fragment 3s;hls_playlist_length 10s;hls_path /usr/local/nginx/html/hls;}}
}#user nobody;
worker_processes  1;#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;#pid logs/nginx.pid;events {
    worker_connections  1024;
}http {
    include       mime.types;default_type  application/octet-stream;#log_format main '$remote_addr - $remote_user [$time_local] "$request" '# '$status $body_bytes_sent "$http_referer" '# '"$http_user_agent" "$http_x_forwarded_for"';#access_log logs/access.log main;sendfile        on;#tcp_nopush on;#keepalive_timeout 0;keepalive_timeout  65;#gzip on;server {
    listen       80;server_name  localhost;#charset koi8-r;#access_log logs/host.access.log main;location / {
    root   html;index  index.html index.htm;}#error_page 404 /404.html;# redirect server error pages to the static page /50x.html#error_page   500 502 503 504  /50x.html;location = /50x.html {
    root   html;}# proxy the PHP scripts to Apache listening on 127.0.0.1:80##location ~ \.php$ {
    # proxy_pass http://127.0.0.1;#}# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000##location ~ \.php$ {
    # root html;# fastcgi_pass 127.0.0.1:9000;# fastcgi_index index.php;# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;# include fastcgi_params;#}# deny access to .htaccess files, if Apache's document root# concurs with nginx's one##location ~ /\.ht {
    # deny all;#}}# another virtual host using mix of IP-, name-, and port-based configuration##server {
    # listen 8000;# listen somename:8080;# server_name somename alias another.alias;# location / {
    # root html;# index index.html index.htm;# }#}# HTTPS server##server {
    # listen 443 ssl;# server_name localhost;# ssl_certificate cert.pem;# ssl_certificate_key cert.key;# ssl_session_cache shared:SSL:1m;# ssl_session_timeout 5m;# ssl_ciphers HIGH:!aNULL:!MD5;# ssl_prefer_server_ciphers on;# location / {
    # root html;# index index.html index.htm;# }#}}

3.重启nginx，开启防火墙端口

(1)重启ngxin服务

 sudo systemctl restart nginx

(2)开启1935端口

sudo firewall-cmd --add-port=1935/tcp --permanent
sudo firewall-cmd --reload

4.测试

(1)设置OBS-Studio的推流地址

rtmp://192.168.1.116:1935/live/

串流密钥随便写，拉流的时候要对应

其中ip为我的CentOS虚拟机的ip地址，将ip改为自己的服务器地址，ip后面的端口号和live是在nginx配置文件里设置的，与配置文件对应
在这里插入图片描述
设置好后在OBS-Studio里添加一个屏幕捕获，然后开始推流.

(2)VLC拉流测试

与nginx配置文件对应的rtmp流和hls流地址

rtmp://192.168.1.116:1935/live/demo

http://192.168.1.116/hls/demo.m3u8

在这里插入图片描述
