nginx简介
Nginx (engine x) 是一个高性能的HTTP和反向代理服务，也是一个IMAP/POP3/SMTP服务，由于项目中需要处理负载均衡
在Docker下载Nginx镜像
# 搜索nginx
docker search ngnix
# 拉去远程的nginx镜像
docker pull ngnix
# 查看镜像
docker images
创建挂载目录
我们这里需要挂载可手动修改配置文件的nginx，而不是全部封装在docker容器中运行的。
mkdir -p /nginx/{conf,conf.d,html,logs}
编写nginx.conf配置文件
编写我们自定义的配置文件放在conf文件夹中
配置文件内容如下
# For more information on configuration, see:

user nginx;

include /usr/share/nginx/modules/*.conf;

worker_connections 1024;
}

listen 80 default_server;
listen [::]:80 default_server;
server_name 120.77.96.184;

# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;

}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;

}
upstream pic{
server 120.77.96.184:8090 weight=1;
server 120.77.96.184:8091 weight=1;
}
}
upstream pics是我们配置的负载均衡服务器切换，我们通过监听请求的80端口，来分配到8090和8091端口的服务器请求。
启动容器
docker run --name mynginx -d -p 80:80 -v /nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v /nginx/logs:/var/log/nginx -d docker.io/nginx
查看容器启动列表
docker ps -a
