导入时

内存错误

---

我无法理解原因。

对于

RHEL

+

启用selinux

+

/tmp作为noexec

，任何试图在

/tmp

中访问和执行的模块都会生成内存错误

在我的例子中，

/tmp

是

noexec

，selinux是强制执行的

/tmp

默认为

默认值、noexec、nosuid、nodev

我设置：查看：

但问题依然存在，如果我正确理解的话，这是因为：

因此上的

httpd\u tmp\u exec-->选项对我没有用处

我查看python库文件，搜索
/tmp
声明，发现
tempfile.py行147
：
def\u candidate\u tempdir\u list（）

在这里，我看到如果有envnames
TMPDIR
，
TEMP
，
TMP
，python将拾取TEMP位置

设置哪个变量？为此，我进入了
libffi
源代码，
libffi-3.0.6
。文件：
src/closures.c
第290行
open_temp_exec_file_env，“TMPDIR”，0

TMPDIR
是要设置的候选项

我继续安装
/opt/app/tmp
，设置
导出TMPDIR=/opt/app/tmp

在我使用
pythonidle
之前，所有这些都可以正常工作，当我继续部署
nginx+uwsgi
时，我也遇到了同样的错误。现在我不知道为什么会发生这种情况，我想一定是执行问题。因此，我首先重新安装了
uwsgi
，然后修改了
nginx.conf
的
/location
，查看：set:
uwsgi\u temp\u路径

我重新启动了所有的服务，nginx，uwsgi。我试过了。成功了

我还首次尝试了：（安全）黑客：

结果令我失望
