This article mainly introduces Centos7 how to install Hue, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

Hue installation

The example is based on Centos7 to install Hue. A large number of software and packages need to be installed before installation, because python and c must depend on packages.

Install the Hue dependency package in Centos7

Yum install ant gcc dependency + libkrb5-dev libmysqlclient-devyum install build-essential gcc-c++yum install python-dev libssl-dev build-essential zlibc zlib-bin libidn11-dev libidn11 zlib-devel# sasl.h required dependency package yum install cyrus-sasl-lib.x86_64 cyrus-sasl-devel.x86_64 libgsasl-devel.x86_64 saslwrapper-devel.x86_64# python xml dependency package yum install libxslt-develpip install lxml# c/_cffi_backend.c:15:17: fatal error: ffi.h:yum Problem solving that cannot be found by install libffi-devel# openssl/opensslv.h yum install openssl-devel# fatal error: lber.h: no file or directory yum install libldap2-dev openldap-devel# egg_info failed with error code 1 inyum install mysql-devel# sqlite3.h: no file or directory yum install gmp-devel sqlite-devel

There is no order in the installation of dependent packages, and basically they will be used.
