主機上Docker和MySQL（外部）內部的HHVM

Question

我使用以下配置在cPanel服務器上的Docker內設置HHVM：

http://wiki.mikejung.biz/HHVM

部分- “如何在cPanel的Ubuntu Docker容器中運行HHVM”

我的Docker配置為：

"Name": "/sad_wozniak",
"NetworkSettings": {
    "Bridge": "docker0",
    "Gateway": "172.17.42.1",
    "IPAddress": "172.17.0.13",
    "IPPrefixLen": 16,
    "MacAddress": "02:42:ac:11:00:0d",
    "PortMapping": null,
    "Ports": {
        "9000/tcp": [
            {
                "HostIp": "0.0.0.0",
                "HostPort": "9000"

並在域的VirtualHost上添加：

    <IfModule mod_proxy_fcgi.c>
            ProxyPassMatch ^/(.*\.php(/.*)?)$ fcgi://172.17.0.13:9000/home/username/public_html/
    </IfModule>

我檢查它是否可以卷曲：

HTTP/1.1 200 OK
Date: Sat, 04 Apr 2015 22:34:52 GMT
Server: Apache
X-Powered-By: HHVM/3.6.1
X-Mod-Pagespeed: 1.9.32.3-4448
Cache-Control: max-age=0, no-cache
Content-Length: 17
Content-Type: text/html; charset=utf-8

但我得到MySQL錯誤：

Error establishing a database connection

外部Docker MySQL服務器有權使用任何遠程連接。 我想在服務器上對MySQL服務器使用“ localhost”。

MySQL運行在：

tcp        0      0 0.0.0.0:3306                0.0.0.0:*                   LISTEN      498        19250361   3206/mysqld

如何將HHVM與Docker外部的MySQL連接？

Answer 1

如文檔所述，您需要將主機地址作為別名添加到容器

http://docs.docker.com/reference/commandline/cli/#adding-entries-to-a-container-hosts-file

Note: Sometimes you need to connect to the Docker host, which means getting the IP address of the host. You can use the following shell commands to simplify this process:

 $ alias hostip="ip route show 0.0.0.0/0 | grep -Eo 'via \S+' | awk '{ print \$2 }'"
 $ docker run  --add-host=docker:$(hostip) --rm -it debian

之后，您應該能夠從容器使用地址docker:3306連接到主機MySQL。
