docker搭建nginx实现负载均衡

docker搭建nginx实现负载均衡 安装nginx

查询安装

[root@localhost ~]# docker search nginx [root@localhost ~]# docker pull nginx

准备 创建一个空的nginx文件夹里面在创建一个nginx.conf文件和conf.d文件夹

运行映射之前创建的文件夹 端口：8075映射80

docker run -it \ --name nginx \ -p 8075:80 \ -p 8080:8080 \ --privileged \ --network wn_docker_net \ --ip 172.18.12.90 \ -v /etc/localtime:/etc/localtime \ -v /usr/local/software/nginx/conf/nginx.conf:/etc/nginx/nginx.conf \ -v /usr/local/software/nginx/html:/usr/share/nginx/html \ -v /usr/local/software/nginx/conf/conf.d:/etc/nginx/conf.d \ -v /usr/local/software/nginx/logs:/var/log/nginx \ -d nginx 配置实现负载均衡

打开nginx.conf

在http中配置

完整的文件内容：

user nginx; worker_processes auto; error_log /var/log/nginx/error.log notice; pid /var/run/nginx.pid; events { worker_connections 1024; } http { include /etc/nginx/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 /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; keepalive_timeout 65; #gzip on; #myCode： #配置上有服务器，形成负载 upstream activityBalance{ server 192.168.133.100:15348 weight=1; server 192.168.200.113:15348 weight=1; } server{ keepalive_requests 120; #单连接请求上限次数 listen 8080; #监听端口号 location /api/{ proxy_pass http://activityBalance/api/; #反向代理服务器的访问地址 proxy_set_header Host $host; #主机ip proxy_set_header X-real-ip $remote_addr; #客户端访问的真实ip proxy_set_header X-Fowarded-For $proxy_add_x_forwarded_for; #代理转发历史 proxy_redirect off; } } include /etc/nginx/conf.d/*.conf; }

此时访问nginx会负载均衡到两个服务器
