1、操作背景
操作系统版本:CentOS Linux release 7.4.1708 (Core) nginx版本:1.13.4
nginx从1.9.0版本开始,新增了ngx_stream_core_module模块,使nginx支持四层负载均衡。默认编译的时候该模块并未编译进去,需要编译的时候添加--with-stream,使其支持stream代理。
2、nginx编译添加stream模块
2.1、查看原nginx编译参数
[root@test-server sbin]# nginx -V nginx version: nginx/1.13.4 built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) built with OpenSSL 1.0.2k-fips 26 Jan 2017 TLS SNI support enabled configure arguments: --prefix=/usr/local/nginx --user=www --group=www --with-http_ssl_module --with-http_gzip_static_module --http-client-body-temp-path=/usr/local/nginx/tmp/client/ --http-proxy-temp-path=/usr/local/nginx/tmp/proxy/ --http-fastcgi-temp-path=/usr/local/nginx/tmp/fcgi/ --with-poll_module --with-file-aio --with-http_realip_module --with-http_addition_module --with-http_addition_module --with-http_random_index_module --with-http_stub_status_module --http-uwsgi-temp-path=/usr/local/nginx/uwsgi_temp --http-scgi-temp-path=/usr/local/nginx/scgi_temp --with-pcre=/usr/local/src/pcre-8.41
2.2、添加stream模块进行重新编译

此处nginx源码目录为: /usr/local/src/nginx-1 .13.4,即为编译命令执行目录。 编译命令如下: . /configure --prefix= /usr/local/nginx --user=www --group=www --with-http_ssl_module --with-http_gzip_static_module --http-client-body-temp-path= /usr/local/nginx/tmp/client/ --http-proxy-temp-path= /usr/local/nginx/tmp/proxy/ --http-fastcgi-temp-path= /usr/local/nginx/tmp/fcgi/ --with-poll_module --with- file -aio --with-http_realip_module --with-http_addition_module --with-http_addition_module --with-http_random_index_module --with-http_stub_status_module --http-uwsgi-temp-path= /usr/local/nginx/uwsgi_temp --http-scgi-temp-path= /usr/local/nginx/scgi_temp --with-pcre= /usr/local/src/pcre-8 .41 --with-stream |
2.3、进行make操作
此处nginx源码目录为:/usr/local/src/nginx-1.13.4,即为编译命令执行目录。 make 此处一定不能使用make install命令,执行该命令会将原有nginx目录进行覆盖。
3、关停nginx同时复制新的nginx启动文件

关闭nginx服务 systemctl stop nginx 备份原有nginx二进制文件。 cp /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx-no-strem 复制新编译好的nginx二进制文件。从此处nginx源码目录为: /usr/local/nginx-1 .13.4。即为编译命令执行目录。 cp . /objs/nginx /usr/local/nginx/sbin/nginx |
4、启动测试
启动nginx。 systemctl start nginx 查看nginx模块信息。 nginx -V nginx version: nginx/1.13.4 built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) built with OpenSSL 1.0.2k-fips 26 Jan 2017 TLS SNI support enabled configure arguments: --prefix=/usr/local/nginx --user=www --group=www --with-http_ssl_module --with-http_gzip_static_module --http-client-body-temp-path=/usr/local/nginx/tmp/client/ --http-proxy-temp-path=/usr/local/nginx/tmp/proxy/ --http-fastcgi-temp-path=/usr/local/nginx/tmp/fcgi/ --with-poll_module --with-file-aio --with-http_realip_module --with-http_addition_module --with-http_addition_module --with-http_random_index_module --with-http_stub_status_module --http-uwsgi-temp-path=/usr/local/nginx/uwsgi_temp --http-scgi-temp-path=/usr/local/nginx/scgi_temp --with-pcre=/usr/local/src/pcre-8.41 --with-stream 可以看到stream模块已经编译到nginx内了。
5、nginx stream模块配置简析
stream段的配置要与http段在同级目录。此处引用的为官方nginx说明配置。
stream { upstream backend { hash $remote_addr consistent; server backend1.example.com:12345 weight=5; server 127.0.0.1:12345 max_fails=3 fail_timeout=30s; server unix:/tmp/backend3; } upstream dns { server 192.168.0.1:53535; server dns.example.com:53; } server { listen 12345; proxy_connect_timeout 1s; proxy_timeout 3s; proxy_pass backend; } server { listen 127.0.0.1:53 udp reuseport; proxy_timeout 20s; proxy_pass dns; } server { listen [::1]:12345; proxy_pass unix:/tmp/stream.socket; } }
举一个栗子,利用stream模块代理 zk服务的2181端口。

stream { upstream zk_server { server 172.16.3.8:2181 weight=5; } server { listen 2181 tcp; proxy_responses 1; proxy_timeout 20s; proxy_pass zk_server; } } |
6、编译nignx systemd服务启动文件
[Unit] Description=nginx - high performance web server Documentation=http://nginx.org/en/docs/ After=network.target remote-fs.target nss-lookup.target [Service] Type=forking PIDFile=/var/run/nginx.pid ExecStartPre=/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf ExecStart=/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf ExecReload=/bin/kill -s HUP $MAINPID ExecStop=/bin/kill -s QUIT $MAINPID PrivateTmp=true [Install]
