WordPress 在 OpenShift Origin 中使用官方示例

Question

我已经安装 All-In-One OpenShift Origin Virtual Machine (Version 1.1.6) 并按照 origin/examples/wordpress 中给出的说明部署了 WordPress。我选择了 NFS storage

我需要知道：

当我 ls 进入 /home/data/pv0002 时，它按预期显示 MySQL 文件。但是当我 ls 进入 /home/data/pv0001 时，它什么也没显示！不是必须要有 WordPress 文件吗？
当我尝试在 WordPress 中上传媒体时，它显示如下错误消息

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

我该怎么做才能解决这个问题？
当我尝试安装新主题时，它要求提供 ftp 凭据。我需要做什么才能得到它？

Answer 1

在 Centos 7 中，我执行了以下步骤并且一切正常。重要的步骤是 3、4 和 5。并且无需将受限的 scc 编辑为 RunAsAny。

第 1 步：

# systemctl status docker
# systemctl status nfs

第 2 步： 启动集群

第 3 步：

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

第 4 步：

# 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： 来自 wordpress 项目 system:admin

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

这意味着允许此项目中的容器作为 root 运行。

第 6 步： 部署 wordpress
