一、部署环境：
主机：192.168.1.155
部署方式：rancher2.0 手动发布
部署包：dnsmasq nginx （docker镜像）
二、部署配置：
在这里我们使用的是rancher2.0部署镜像，具体操作很简单，在这里就不再赘述了。
dnsmasq和nginx部署完成后如下：
1、dnsmasq
我们可以进入容器去配置dnsmas.conf文件，也可以使用管理页面进行配置。在这里使用UI页面配置：
配置详情：
1 #dnsmasq config, for a complete example, see: 2 # http://oss.segetech.com/intra/srv/dnsmasq.conf 3 #单设置127只为本机使用，加入本机IP为内部全网使用，默认监听主机所有网卡 4 #如果是docker容器部署的，配置监听需要配置容器的虚拟ip 5 #listen-address=127.0.0.1,10.42.0.23 6 #log all dns queries；dnsmasq日志设置 7 log-queries 8 log-facility=/var/log/dnsmasq.log 9 #dont use hosts nameservers 10 #no-resolv 11 resolv-file=/etc/dnsmasq.d/resolv.dnsmasq.conf //在这里我们自定义了nameserver 12 #不读取系统hosts，读取你设定的 13 no-hosts 14 addn-hosts=/etc/dnsmasq.d/dnsmasq.hosts //自定义了hosts 15 #重启后清空缓存 16 clear-on-reload 17 # 完整的域名才向上游服务器查找，如果仅仅是主机名仅查找hosts文件 18 #domain-needed 19 #dnsmasq缓存设置 20 cache-size=2048 21 # 严格按照resolv.conf中的顺序进行查找 22 #strict-order 23 # 也不要检测 /etc/resolv.conf 的变化 24 no-poll 25 #定义主机ip映射 26 address=/irms.boco.com/192.168.1.161 27 address=/wesf-shanxi.irms.boco.com/192.168.1.155
由于我们在上面自定义了resolv和hosts，因此需要到定义的目录下创建对应的文件配置：
vi /etc/dnsmasq.d/resolv.dnsmasq.conf
1 nameserver 192.168.1.155 //或者容器的虚拟ip
vi /etc/dnsmasq.d/dnsmasq.hosts
1 192.168.1.161 irms.boco.com 2 192.168.1.155 websf-shanxi.irms.boco.com
配置完成后restart。
2、nginx
vi /etc/nginx/nginx.conf

配置nginx所在主机的resolv.conf文件（或者是nginx所在容器内）为dnsmasq主机（或容器）的ip。
三、验证结果
域名解析正常，验证成功。
