WAL-E:备份提取后无法重新启动postgresql

这是在Ubuntu 14.04 LTS上

编辑：

使用pip安装WAL-E，并根据说明和密码由

envdir

管理密钥

我正在尝试使用WAL-E恢复一个数据库，最初一切似乎都很顺利，因为我已经安装并运行了Postgres，可以轻松创建或恢复一个数据库，并通过pgadmin本地和远程访问它。当我尝试使用wal-e fetch backup从S3备份执行恢复时，问题就出现了。在开始博士后考试之前，它似乎进展顺利

出现了许多错误，可能是缺少包或权限问题，如下所示：

我做了很多搜索，但没有找到任何有用的东西。任何正确方向的建议或观点都将不胜感激

此外，解决这个问题将非常有意义，以确保我的主安装在需要恢复时能够正常运行。如果我无法恢复备份，备份是毫无意义的。

我不能完全确定是什么解决了

没有找到'wal-e==0.8.1'发行版的问题，但在重新启动时，我再也没有看到过

除此之外，解决这个问题相当简单

许多python发行版上的可执行位未设置

Chowning修复了以下错误：

      chmod o+x /usr/local/lib/python2.7/dist-packages/requests-2.7.0.dist-info/
      chmod o+x /usr/local/lib/python2.7/dist-packages/requests
...

备份标签创建不正确的原因

在Master中运行以下命令


苏博士后

psql-c“选择pg_开始备份（“初始备份”）；”

rsync-cva--inplace--exclude=pg_xlog
/var/lib/postgresql/9.1/main/
从属IP地址：/var/lib/postgresql/9.1/main/

psql-c“选择pg_stop_backup（）；”

cd/var/lib/postgresql/9.1/main

创建文件名recovery.conf添加以下行


待机模式='on'
主\u连接信息='主机=主\u IP\u地址
端口=5432 user=rep password=yourspassword'trigger\u文件=
“/tmp/postgresql.trigger.5432”

服务postgresql重启
如果在dba.stackexchange.com上询问，这会更好。祝你好运。我猜你已经在一些每个用户的位置安装了WAL-E，而不是整个站点，所以当它作为不同的操作系统用户运行时，它找不到它。您是如何安装的？WAL-E是通过pip安装的：
sudo pip install WAL-E
，如图所示，感谢您的反馈，但我认为这不是问题所在，因为我能够通过权限管理解决我的问题。我还让master很高兴地生成夜间基本备份，到目前为止，在该机器上没有任何问题。我对你的答案投了赞成票，但我还没有坚持下去的代表。
