1. Docker 安裝Nginx
[root@langzi01 nginx]# pwd
/data/nginx
[root@langzi01 nginx]# ls
conf conf.d html logs
[root@langzi01 nginx]# docker search nginx
[root@langzi01 nginx]# docker pull nginx:1.14.2
[root@langzi01 nginx]# docker images nginx
REPOSITORY TAG IMAGE ID CREATED SIZE
docker.io/nginx 1.14.2 e706cb01fa6b 2 hours ago 109 MB
##運(yùn)行容器
[root@langzi01 nginx]# docker run --name mynginx -d -p 82:80 -v /data/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v /data/nginx/logs:/var/log/nginx -d docker.io/nginx
命令說(shuō)明：
-p 80:80：將容器的80端口映射到主機(jī)的80端口
--name mynginx：將容器命名為mynginx
## -v $PWD/www:/www：將主機(jī)中當(dāng)前目錄下的www掛載到容器的/www
-v /data/nginx/conf/nginx.conf:/etc/nginx/nginx.conf：將主機(jī)中當(dāng)前目錄下的nginx.conf掛載到容器的/etc/nginx/nginx.conf
-v /data/nginx/logs:/var/log/nginx：將主機(jī)中當(dāng)前目錄下的logs掛載到容器的/var/log/nginx
其中nginx.conf的內(nèi)容如下
[root@langzi01 nginx]# cat conf/nginx.conf

2. Docker 安裝Tomcat
[root@langzi01 tomcat]# pwd
/data/tomcat
[root@langzi01 tomcat]# ls
conf logs test webapps
[root@langzi01 test]# docker images|grep tomcat
docker.io/tomcat 8.5 168588387c68 3 weeks ago 463 MB
docker.io/tomcat latest 168588387c68 3 weeks ago 463 MB
#啟動(dòng)兩個(gè)tomcat服務(wù)
[root@langzi01 test]# docker run --name tomcat1 -p 8088:8080 -v $PWD/test:/usr/local/tomcat/webapps/test -d tomcat
[root@langzi01 test]# docker run --name tomcat2 -p 8089:8080 -v $PWD/test:/usr/local/tomcat/webapps/test -d tomcat
[root@langzi01 test]# docker ps -a|grep tomcat

# 訪問(wèn)
[root@langzi01 test]# curl '172.17.0.1:8088'
[root@langzi01 test]# curl '172.17.0.1:8089'
3. nginx代理tomcat服務(wù)器
upstream pic{
server 172.17.0.1:8088 weight=5;
server 172.17.0.1:8089 weight=5;
}
查看nginx的端口
[root@langzi01 test]# docker ps -a|grep nginx
cce508aa20bc docker.io/nginx "nginx -g 'daemon ..." About an hour ago Up 58 minutes 0.0.0.0:82->80/tcp mynginx
我的公網(wǎng)ip為：http://47.104.136.162 瀏覽器訪問(wèn)：http://47.104.136.162:82/
結(jié)果如下：
