WordPress在OpenShift Origin中使用官方示例

Question

我已经按照origin/examples/WordPress中的说明安装了All-In-One OpenShift Origin Virtual Machine (Version 1.1.6)并部署了WordPress。我选择了NFS存储

我需要知道：

1. 当我在/home/data/pv0002中ls时，它会按预期显示MySQL文件。但当我ls进入/home/data/pv0001时，它什么也没显示！WordPress文件不是必须在那里吗？

2. 当我尝试在WordPress中上传媒体时，它会显示一条错误消息，如下面的

   Unable to create directory wp-content/uploads/2016/05. Is its parent directory writable by the server?

   我该怎么办才能解决这个问题？

3. 当我尝试安装新主题时，它会要求提供ftp凭据。我该怎么做才能得到它？

Answer 1

从Centos 7开始，我完成了以下步骤，一切都很顺利。重要步骤是3、4和5。并且无需将受限制的scc编辑为RunAsAny。

步骤1:

# systemctl status docker
# systemctl status nfs

步骤2:启动集群

步骤3:

# mkdir -p /home/data/pv0001
# mkdir -p /home/data/pv0002
# chmod -R 777 /home/data/
# chown -R nfsnobody:nfsnobody /home/data/

步骤4:

# cat /etc/exports
/home/data/pv0001 *(rw,sync,no_root_squash)
/home/data/pv0002 *(rw,sync,no_root_squash)
# exportfs -a
# setsebool -P virt_use_nfs 1

第5步：以及来自wordpress项目的system:admin

# oadm policy add-scc-to-user anyuid -z default

这意味着允许该项目中的容器以root身份运行。

第6步：部署wordpress
