在centos 7上安装python netsnmp

Question

我收到这个错误fatal error: net-snmp/net-snmp-config.h: No such file or directory。我已经安装了gcc, python-devel, net-snmp, net-snmp-utils, net-snmp-python和其他开发依赖项。

CentOS Linux release 7.1.1503 (Core)
[admin@localhost python]$ wget http://sourceforge.net/projects/net-snmp/files/net-snmp/5.5.2/net-snmp-5.5.2.tar.gz

UPDATE1:在netsnmp source dir上运行./configure && make && make install之后，我可以运行python setup.py install。但是，现在我从python得到这个错误：

>>> import netsnmp
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "netsnmp/__init__.py", line 1, in <module>
    from client import *
  File "netsnmp/client.py", line 1, in <module>
    import client_intf
ImportError: No module named client_intf
>>> 

更新2:我的错！！我在netsnmp source dircd /tmp/net-snmp-master/python/目录下运行python解释器，这导致我给出了预期的错误，因为python不是从egg中使用导入，而是从源代码中。无论如何，在做了一个cd ~之后，我得到了一个新的错误

>>> import netsnmp
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "build/bdist.linux-x86_64/egg/netsnmp/__init__.py", line 1, in <module>

ImportError: libnetsnmp.so.30: cannot open shared object file: No such file or directory
>>> exit()

更新3

[root@localhost ~]# sudo ldconfig
[root@localhost ~]# sudo ldconfig -p | grep netsnmp

[root@localhost ~]# 

UPDATE4：通过运行sudo ldconfig并修改/etc/ld.so.conf.d/libc.conf，最终解决了问题

[root@localhost ~]# cat /etc/ld.so.conf
include ld.so.conf.d/*.conf
[root@localhost ~]# cat > /etc/ld.so.conf.d/libc.conf <<EOF
> /usr/local/lib
> EOF
[root@localhost ~]# ldconfig
[root@localhost ~]# python
>>> import netsnmp
>>> exit()
[root@localhost ~]#

确保已安装net-snmp-devel。 检查现有的/usr/include/net snmp/net snmp config.h
