如何为python脚本导入LD_LIBRARY_PATH？ 无root权限。 无权重启apache服务器

Question

I have a shared hosting in GoDaddy hosting service.It has the following limitations.

• No root access
• No permission to restart apache server

My hosting service system and applications specifications.

• Postgres 10.7
• python3
• OS -- Linux version 2.6.32-896.16.1.lve1.4.54.el6.x86_64 (mockbuild@buildfarm03.cloudlinux.com) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-18)

I use a cgi script to redirect the apache server to my Python script. When Python tries to import the psycopg2 module, the following error is thrown

 /home/user/python_base/lib/python3.4/site-packages/psycopg2/_psycopg.cpython-34m.so: undefined symbol: PQescapeIdentifier

I exported the postgresql/lib path to LD_LIBRARY_PATH and restarted the Python script locally and it works fine.

But since I cannot restart the apache server, I guess the process in which the apache is running does not have the LD_LIBRARY_PATH updated. So the error persists. I have a python environment running. I copied all the library files from postgresql/lib to mypythonenv/lib , still in vain.

您可以在导入psycopg2 之前在os.environ设置环境变量。
