linux系统安装mysqlclient的时候往往会报错，导致django项目无法启动，本文主要解决这个问题

解决方式1：直接找到mysqlclient的whl安装包

python3.8-x86-64位

通过如下仓库，下载mysqlclient的安装包：https://github.com/HMTeen/Linux-Python-mysqlclient

通过远程连接软件复制到服务器

安装：

pip install mysqlclient-2.2.1-cp38-cp38-linux_x86_64.whl

其他适配版本的whl安装包

参考这位大神的仓库：https://github.com/xizhicode/mysqlclient_builds

解决方法2：先安装相关依赖，再单独安装mysqlclient

rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022
yum install mysql-devel
yum install python-devel
pip install mysqlclient

解决方式3：根据错误信息找到根源，一步一步解决
