我有一个在 Centos7 服务器上运行良好的 django (1.7) 应用程序。现在我转移到生产服务器 RHEL 6 并且仍然有一些问题。

问题是 mod_wsgi。

服务器配置：

  • RHEL6
  • 阿帕奇 2.2
  • 姜戈 1.7
  • 蟒蛇2.6

ldd 模块/mod_wsgi.so

linux-vdso.so.1 =>  (0x00007fff6afff000)
    libpython2.6.so.1.0 => /usr/lib64/libpython2.6.so.1.0 (0x00007fd69fc02000)

    /lib64/ld-linux-x86-64.so.2 (0x000000330aa00000)

我认为一个问题可能是 mod_wsgi 似乎是用 lib64 编译的，所以我将 flweb.conf 上的 python 路径更改为 lib64 但它没有用

编辑： 我意识到服务器在 /user/local/lib 中有 python 2.7，这是安装 django 的 python 版本。我更改了conf文件中的路径，但现在我想我需要重建mod_wsgi

EDIT2： 试图重建 mod_wsgi，有这个问题

/usr/bin/ld: /usr/local/lib/libpython2.7.a(abstract.o): relocation R_X86_64_32 against `.rodata.str1.8' can not be used when making a shared object; recompile with -fPIC

根据https://code.google.com/p/modwsgi/wiki/InstallationIssues是编译成 32 位的 python 和 mod_wsgi 到 64 之间的冲突
