查看目录：/usr/bin 发现有python3.6，则可以不用安装python3.6
查看python和python3.6
python -V python3.6 —V
python和python2.7建立了软连接，现在把python的软连接删除，改成和python3.6建立软连接
python的软连接在/usr/bin目录下，找到、删除
建立新的python软连接
[root@iZbp1i8olg1ggbwnm1ja5jZ ~]# ln -s /usr/bin/python3.6 /usr/bin/python [root@iZbp1i8olg1ggbwnm1ja5jZ ~]# python -V Python 3.6.8 [root@iZbp1i8olg1ggbwnm1ja5jZ ~]# python Python 3.6.8 (default, Apr 2 2020, 13:34:55) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)] on linux Type "help", "copyright", "credits" or "license" for more information. >>> exit()
建立pip软连接（和python软连接类似）
[root@iZbp1i8olg1ggbwnm1ja5jZ ~]# ln -s /usr/bin/pip3.6 /usr/bin/pip
[root@iZbp1i8olg1ggbwnm1ja5jZ ~]# pip -V

修改yum依赖
vim /usr/bin/yum 将/usr/bin/python改为/usr/bin/python2.7
vim /usr/libexec/urlgrabber-ext-down 将/usr/bin/python改为/usr/bin/python2.7
vim 操作：按键i---编辑，按键esc---退出编辑，输入“：”，在输入“wq”保存退出，“q”直接退出
检验yum

注意代码，有错，
MariaDB [(none)]> show variables like “%character%”;show variables like “%collation%” ;
引号因该是英文的！！！！！！
Maria DB使用操作传送门
三、Centos 7下安装配置Nginx传送门 四、centos7安装和配置uWSGI传送门若出现安装错误，解决办法注意：检验的时候访问服务器IP一定要加端口！！！！！
五、往服务器传输项目文件1.Xshell 与 Xftp 的安装与使用 传送门
2.修改项目
修改.vue文件，把对django的强求地址改成服务器IP地址
114.55.239.206是我的服务器IP
后端django文件修改
3.unzip安装传送门
解压项目包
六、把项目的nginx、uwsgi和setting文件配好参考链接
nginx相关命令传送门
七、centos7安装vue环境传送门打包vue项目，会生成dist文件夹，版本的更新修改dist文件即可
若dist文件里面没有static文件夹，解决方法
八、Mariadb数据库迁移，导出，导入1、导出导入
2、数据库迁移
a.在服务器上用migrate命令
b.把本地sql文件传输到服务器，然后复制到Mariadb
参考链接j
九、杀死端口和进程操作参考链接1
参考链接2
十、uwsgi开机自启动 传送门
