本文主要是介绍centos7.5 Nginx+rtmp 搭建流媒体服务器，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
centos7.5 Nginx+rtmp 搭建流媒体服务器
一. gcc 安装
安装 nginx 需要先将官网下载的源码进行编译，编译依赖 gcc 环境，如果没有 gcc 环境，则需要安装：
yum -y install gcc gcc-c++
二. PCRE pcre-devel 安装
PCRE(Perl Compatible Regular Expressions) 是一个Perl库，包括 perl 兼容的正则表达式库。nginx 的 http 模块使用 pcre 来解析正则表达式，所以需要在 linux 上安装 pcre 库，pcre-devel 是使用 pcre 开发的一个二次开发库。nginx也需要此库。命令：
yum install -y pcre pcre-devel
三. zlib 安装
zlib 库提供了很多种压缩和解压缩的方式， nginx 使用 zlib 对 http 包的内容进行 gzip ，所以需要在 Centos 上安装 zlib 库。
yum install -y zlib zlib-devel
四. OpenSSL 安装
OpenSSL 是一个强大的安全套接字层密码库，囊括主要的密码算法、常用的密钥和证书封装管理功能及 SSL 协议，并提供丰富的应用程序供测试或其它目的使用。nginx 不仅支持 http 协议，还支持 https（即在ssl协议上传输http），所以需要在 Centos 安装 OpenSSL 库。
1、第一种安装方式
yum install -y openssl openssl-devel
2、第二种安装方式（源码编译安装）
sudo wget https://www.openssl.org/source/openssl-1.1.0e.tar.gzsudo tar -zxvf openssl-1.1.0e.tar.gzcd openssl-1.1.0e/sudo ./configsudo makesudo make install3、第三种安装方式（已经使用此方案，安装成功）
# 查看openssl版本
openssl version下载openssl
sudo wget https://www.openssl.org/source/openssl-1.1.0e.tar.gz解压并编译安装
tar -zxvf openssl-1.1.1c.tar.gz
cd openssl-1.1.1c
./config --prefix=/usr/local/openssl #如果此步骤报错,需要安装perl以及gcc包
make && make install
mv /usr/bin/openssl /usr/bin/openssl.bak
ln -sf /usr/local/openssl/bin/openssl /usr/bin/openssl
echo "/usr/local/openssl/lib" >> /etc/ld.so.conf
ldconfig -v # 设置生效# 查看openssl版本
openssl version
五、安装nginx 跟rtmp MP4模块
1.官网下载直接下载.tar.gz安装包
下载Nginx
wget http://nginx.org/download/nginx-1.12.1.tar.gz下载 Rtmp
wget https://github.com/arut/nginx-rtmp-module/archive/v1.2.0.tar.gz
下载flv和mp4支持模块
wget http://h264.code-shop.com/download/nginx_mod_h264_streaming-2.2.7.tar.gz
2.解压
tar -zxvf nginx-1.12.1.tar.gz
tar -zxvf nginx_mod_h264_streaming-2.2.7.tar.gz
tar -zxvf v1.2.0.tar.gz
3、修改配置nginx openssl 的配置文件，否则会找不到openssl库
修改配置文件不然会报openssl库找不到错误
修改 /home/nginxdir/nginx-1.12.1/auto/lib/openssl/conf文件
增加下面这个分支替换增加的路径
if [ $ngx_found = no ]; thenngx_feature="OpenSSL library in //root/liushen/nginx/openssl-OpenSSL_1_1_0f/bin/include"ngx_feature_path="/root/liushen/nginx/openssl-OpenSSL_1_1_0f/bin/include"if [ $NGX_RPATH = YES ]; thenngx_feature_libs="-R/root/liushen/nginx/openssl-OpenSSL_1_1_0f/bin/lib -L/root/liushen/nginx/openssl-OpenSSL_1_1_0f/bin/ -lssl -lcrypto $NGX_LIBDL"elsengx_feature_libs="-L/root/liushen/nginx/openssl-OpenSSL_1_1_0f/bin/lib -lssl -lcrypto $NGX_LIBDL"fi. auto/featurefi
增加后截图如下：
4、生成Makefile
第1种方案直接编译生成带有指定模块功能的nginx服务程序：
./configure --prefix=/usr/local/nginx --add-module=../nginx-rtmp-module-1.2.0 --add-module=../nginx_mod_h264_streaming-2.2.7 --with-http_ssl_module --with-pcre=/home/nginx_dir/nginxdir/pcre-8.35 --with-zlib=/home/nginx_dir/nginxdir/zlib-1.2.11 --user=www --group=www --with-http_flv_module --with-http_mp4_module --with-http_stub_status_module
make && make install
注意：
4.1、依赖包的路径，最好是加进去，不过不加也可以
4.2、第2种方案：先编译安装nginx-rtmp-module-1.2.0 ，然后后期再编译nginx_mod_h264_streaming-2.2.7 ，然后删除安装目录中的nginx文件，将/home/nginxdir/nginx-1.12.1/objs下的编译好的nginx文件，复制到安装目录/usr/local/nginx/sbin
4.3、编译时如果报weberror的错误，将/home/nginxdir/nginx-1.12.1/objs/Makefile 中的-weberror删除掉，重新编译，其余的错误，就是那里报错，注释哪里
4.4.修改配置文件。进入 /usr/local/nginx/conf 文件夹。增添rtmp部分
rtmp {server {listen 1935; #监听的端口 chunk_size 4000;application live { #rtmp推流请求路径 live on;recorder rec1 {record all manual;record_unique on;record_notify on;record_max_size 512M;#record_interval 0s;record_path /usr/local/nginx/html/flv_file;record_suffix .flv;# exec_record_done /usr/local/nginx/shell/upload2oss.sh $path $filename $basename;}}}
}http server块中添加如下部分：
root /usr/local/nginx/html/flv_file/;#limit_rate_after 5m; ####在flv视频文件下载了5M以后开始限速
#limit_rate 512k; ####速度限制为512Kindex index.html;charset utf-8;location ~ \.flv {flv;}location ~ \.mp4$ {
mp4;
}error_page 500 502 503 504 /50x.html;location = /50x.html {root html;}location / {root html;index index.html index.htm;}location /control {rtmp_control all;}
5、进入 /usr/local/nginx/sbin文件夹，执行./nginx启动nginx
备注：nginx.conf配置文件1内容如下：
user root root;worker_processes 1;
#error_log logs/error.log;events {worker_connections 1024;
}# RTMP configuration

搭建期间所碰到的问题：
nginx: [error] open() "/usr/local/nginx//logs/nginx.pid" failed
首先ps aux | grep nginx查看nginx进程号
这里会发现跑了两个，我们要杀死nginx：master 和worker 这2个主进程，我这里的主进程号事27767 27768
使用kill -9 27767杀死
使用kill -9 27768杀死
此问题参考网址1：https://blog.csdn.net/weixin_44352609/article/details/93242894
此问题参考网址2：https://blog.csdn.net/weixin_45525272/article/details/107980445
其实只要正常执行 sudo ./nginx -s stop
再运行 sudo ./nginx
一般都是可以的
