mysql - Django 无法在 RHEL 7 中配置 MySQL

Question

我是 Red Hat 7 的新手，正在尝试在我的 django 项目中配置 MySQL 而不是默认的 sqlite3。我成功安装了 MySQL，如下所示。

[user@user111 django-project]$ mysql --version
mysql  Ver 14.14 Distrib 5.7.22, for Linux (x86_64) using  EditLine wrapper
[user@user111 django-project]$ which mysql
/usr/bin/mysql
[user@user111 django-project]$ mysql -u root -p

现在我想用 MySQL 配置 Django，所以我尝试安装 mysqlclient

[user@user111 django-project]$ pip3 install mysqlclient
Collecting mysqlclient
  Using cached https://files.pythonhosted.org/packages/6f/86/bad31f1c1bb0cc99e88ca2adb7cb5c71f7a6540c1bb001480513de76a931/mysqlclient-1.3.12.tar.gz
    Complete output from command python setup.py egg_info:
    /bin/sh: mysql_config: command not found
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/tmp/pip-build-zn7_jg6q/mysqlclient/setup.py", line 17, in <module>
        metadata, options = get_config()
      File "/tmp/pip-build-zn7_jg6q/mysqlclient/setup_posix.py", line 44, in get_config
        libs = mysql_config("libs_r")
      File "/tmp/pip-build-zn7_jg6q/mysqlclient/setup_posix.py", line 26, in mysql_confi[user@user111 django-project]$ g
        raise EnvironmentError("%s not found" % (mysql_config.path,))
    OSError: mysql_config not found

    ----------------------------------------

现在，出现找不到mysql-config的错误。要安装 mysql-config 我尝试了以下操作

[user@user111 django-project]$ yum install libmysqlclient-dev
Loaded plugins: enabled_repos_upload, langpacks, package_upload, product-id, search-disabled-repos, subscription-manager
....
Repo rhel-7-workstation-satellite-tools-6.2-rpms forced skip_if_unavailable=True due to: /etc/pki/entitlement/4173239949270255333-key.pem
Cannot upload enabled repos report, is this client registered?

This answer on stackoverflow正在帮助我下载 libmysqlclient-dev 但在下载时出现此错误 无法上传已启用的 repo 报告，此客户端已注册吗？ 我不知道该怎么做处理？

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Answer 1

您遵循的说明似乎是针对 Ubuntu，而不是 CentOS。对于 CentOS，假设你通过 yum 安装了 MySQL，试试这个命令来安装你需要的开发包:

yum install mysql-community-devel

然后再次尝试您的pip3 install。祝你好运!
