CentOS 7安装mycli（踩坑无数的经验贴）

CentOS 7升级Python3，然后安装Mycli

1.配置阿里pip仓库

mkdir ~/.pip/
vim ~/.pip/pip.conf                    # 添加以下内容
    [global]
    index-url = https://mirrors.aliyun.com/pypi/simple/

    [install]
    trusted-host=mirrors.aliyun.com

2.安装pip，然后用pip安装mycli

yum install -y python-pip python-devel libffi-devel openssl-devel
pip install --upgrade pip
pip install --ignore-installed mycli==1.10.0		#  python2.7可运行的最高版本，否则运行不了
pip install pymysql==0.9.2											

3.启用mycli

mycli -v
mycli -uroot -p123456
