为通过yum安装的Nginx添加nginx-rtmp-module

发表于 分类于 ，

Nginx 一般都是编译安装，不过它本身也提供了通过yum安装的方式，比如在CentOS 7中需要先安装 Yum 源：

1
rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

之后就是常规的 yum -y install nginx 。

通过这一方式安装的Nginx已经可以通过系统服务的方式进行启动，相当便捷，但是很多有趣的第三方插件并没有能够加入，比如header-more-nginx-module，Nginx目前看来不像Tengine是可以后期动态添加模块的，所以解决的方案出了编译安装似乎没有其他的方式了。

不过Nginx编译只生成一个二进制文件，那么，如果获取yum安装的Nginx编译参数，之后使用同一版本的源代码进行编译，之后替换生成文件就可以了。

安装 nginx

yum -y install nginx

查看原来的 nginx 编译参数

nginx -V

输出如下：

nginx version: nginx/1.12.2
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC)
built with OpenSSL 1.0.2k-fips  26 Jan 2017

获取对应的 Nginx 源码

wget https://nginx.org/download/nginx-1.12.2.tar.gz

获取nginx-rtmp-module源码：

git clone https://github.com/arut/nginx-rtmp-module.git
cd nginx-rtmp-module
git checkout $(git describe --abbrev=0 --tags)

安装依赖

yum -y install {GeoIP,gd,gperftools,libxml2,libxslt,openssl,pcre,perl,zlib}-devel perl-ExtUtils-Embed redhat-rpm-config

编译安装

在获得的编译参数中加入 nginx-rtmp-module 源码的路径，如： --add-module=../nginx-rtmp-module 。然后执行 configure

./configure --prefix=/usr/share/nginx \
    --sbin-path=/usr/sbin/nginx \
    --modules-path=/usr/lib64/nginx/modules \
    --conf-path=/etc/nginx/nginx.conf \
    --error-log-path=/var/log/nginx/error.log \
    --http-log-path=/var/log/nginx/access.log \
    --http-client-body-temp-path=/var/lib/nginx/tmp/client_body \
    --http-proxy-temp-path=/var/lib/nginx/tmp/proxy \
    --http-fastcgi-temp-path=/var/lib/nginx/tmp/fastcgi \
    --http-uwsgi-temp-path=/var/lib/nginx/tmp/uwsgi \
    --http-scgi-temp-path=/var/lib/nginx/tmp/scgi \
    --pid-path=/run/nginx.pid \
    --lock-path=/run/lock/subsys/nginx \
    --user=nginx \
    --group=nginx \
    --with-file-aio \
    --with-ipv6 \
    --with-http_ssl_module \
    --with-http_v2_module \

    --with-http_geoip_module=dynamic \

    --with-http_stub_status_module \
    --with-http_perl_module=dynamic \
    --with-mail=dynamic \
    --with-mail_ssl_module \
    --with-pcre \
    --with-pcre-jit \
    --with-stream=dynamic \
    --with-stream_ssl_module \
    --with-google_perftools_module \
    --with-debug \
    --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -mtune=generic' \
    --with-ld-opt='-Wl,-z,relro -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -Wl,-E' \
    --add-module=../nginx-rtmp-module

停止运行现在的Nginx，然后执行编译安装：

systemctl stop nginx

make
make install

禁止 yum 更新 nginx

修改 yum.conf :

nano /etc/yum.conf

在文件中加入下面配置顶：

exclude=nginx*

修改后的 yum.conf 看起来是这样的：

[main]
cachedir=/var/cache/yum/$basearch/$releasever
keepcache=0
debuglevel=2
logfile=/var/log/yum.log
exactarch=1
obsoletes=1
gpgcheck=1
plugins=1
installonly_limit=5
bugtracker_url=http://bugs.centos.org/set_project.php?project_id=19&ref=http://bugs.centos.org/bug_report_page.php?category=yum
distroverpkg=centos-release

#  This is the default, if you make this bigger yum won't see if the metadata
# is newer on the remote and so you'll "gain" the bandwidth of not having to
# download the new metadata and "pay" for it by yum not having correct
# information.
#  It is esp. important, to have correct metadata, for distributions like
# Fedora which don't keep old packages around. If you don't like this checking
# interupting your command line usage, it's much better to have something
# manually check the metadata once an hour (yum-updatesd will do this).
# metadata_expire=90m

# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d

exlude=nginx*

这样，使用 yum update 命令升级系统的时候就不会再升级 nginx 相关的软件包了。
