yum安装nginx没有某一模块，该如何添加第三方模块？
本文将以添加--with-stream模块为例，演示如何去添加新的模块进去。
需求：生产有个接口是通过socket通信。nginx1.9开始支持tcp层的转发，通过stream实现的，而socket也是基于tcp通信。
实现方法：Centos7.5下yum直接安装的nginx，添加新模块支持tcp转发;重新编译Nginx并添加--with-stream参数。
实现过程：
- 1.查看nginx版本模块
nginx -V nginx version: nginx/1.20.1 built by gcc 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) built with OpenSSL 1.1.1g FIPS 21 Apr 2020 TLS SNI support enabled configure arguments: --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

--with-ld-opt='-Wl,-z,relro -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -Wl,-E'2.下载一个同版本可编译的nginx
cd /opt wget http://nginx.org/download/nginx-1.20.1.tar.gz tar xf nginx-1.20.1.tar.gz && cd nginx-1.20.1
3.备份原nginx文件
mv /usr/sbin/nginx /usr/sbin/nginx.bak cp -r /etc/nginx{,.bak}4.重新编译nginx
检查模块是否支持，比如这次添加 limit 限流模块 和 stream 模块:./configure --help | grep limit--without-http_limit_conn_module disable ngx_http_limit_conn_module--without-http_limit_req_module disable ngx_http_limit_req_module--without-stream_limit_conn_module disable ngx_stream_limit_conn_moduleps：-without-http_limit_conn_module disable 表示已有该模块，编译时，不需要添加./configure –help | grep stream --without-http_upstream_hash_module disable ngx_http_upstream_hash_module --without-http_upstream_ip_hash_module disable ngx_http_upstream_ip_hash_module --without-http_upstream_least_conn_module disable ngx_http_upstream_least_conn_module --without-http_upstream_random_module disable ngx_http_upstream_random_module --without-http_upstream_keepalive_module disable ngx_http_upstream_keepalive_module --without-http_upstream_zone_module disable ngx_http_upstream_zone_module --with-stream enable TCP/UDP proxy module --with-stream=dynamic enable dynamic TCP/UDP proxy module --with-stream_ssl_module enable ngx_stream_ssl_module --with-stream_realip_module enable ngx_stream_realip_module --with-stream_geoip_module enable ngx_stream_geoip_module --with-stream_geoip_module=dynamic enable dynamic ngx_stream_geoip_module --with-stream_ssl_preread_module enable ngx_stream_ssl_preread_module --without-stream_limit_conn_module disable ngx_stream_limit_conn_module --without-stream_access_module disable ngx_stream_access_module --without-stream_geo_module disable ngx_stream_geo_module --without-stream_map_module disable ngx_stream_map_module --without-stream_split_clients_module disable ngx_stream_split_clients_module --without-stream_return_module disable ngx_stream_return_module --without-stream_set_module disable ngx_stream_set_module --without-stream_upstream_hash_module disable ngx_stream_upstream_hash_module --without-stream_upstream_least_conn_module disable ngx_stream_upstream_least_conn_module --without-stream_upstream_random_module disable ngx_stream_upstream_random_module --without-stream_upstream_zone_module disable ngx_stream_upstream_zone_module
ps：–with-stream enable 表示不支持，编译时要自己添加该模块
根据第1步查到已有的模块，加上本次需新增的模块:--with-streamcd /opt/nginx-1.20.1 ./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

--add-module=/opt/nginx_tar/ngx_http_proxy_connect_module以上编译时，如出现缺少依赖，一般需要安装以下模块，安装完再次编译：yum -y install libxml2 libxml2-dev libxslt-develyum -y install gd-develyum -y install perl-devel perl-ExtUtils-Embedyum -y install GeoIP GeoIP-devel GeoIP-datayum -y install pcre-develyum -y install openssl openssl-develyum -y install gcc5.编译通过，继续验证
继续输入：makemake完成后不要继续输入make install，以免现在的nginx出现问题。以上完成后，会在objs目录下生成一个nginx文件，先验证：/opt/nginx-1.12.2/objs/nginx -t/opt/nginx-1.12.2/objs/nginx -V6.替换Nginx文件并重启cp /opt/nginx-1.12.2/objs/nginx /usr/sbin/nginx -s reload7.检查nginx -Vnginx version: nginx/1.20.1built by gcc 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC)built with OpenSSL 1.0.2k-fips 26 Jan 2017TLS SNI support enabledconfigure arguments: --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_auth_request_module --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module=dynamic --with-http_image_filter_module=dynamic --with-http_geoip_module=dynamic --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_degradation_module --with-http_slice_module --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-debug --with-stream新添加的模块在最后，添加模块成功。
