python mac下环境配置笔记

我当前的系统：OS X Yosemite 10.10.5

PyCharm激活:http://idea.qinxi1992.cn

配置MySQL遇到的坑:

MySQL-python安装完成后找不到mysql指定解决办法：

$ sudo ln -s /usr/local/mysql/bin/* /usr/bin

然后无法登陆mysql解决步骤：

一：在系统偏好设置停止MySQL服务

二：以管理员身份启动MySQL安全模式

sudo/usr/local/mysql/bin/mysqld_safe--skip-grant-tables

执行结果如下：

2016-06-12T08:29:17.6NZ mysqld_safe Logging to'/usr/local/mysql/data/lyqdeMacBook-Pro.local.err'.2016-06-12T08:29:17.6NZ mysqld_safe Starting mysqld daemon with databasesfrom/usr/local/mysql/data

三：不要关闭该终端，command+n新建一个输入如下命令:

/usr/local/mysql/bin/mysql

看到下面的信息表示登陆成功:

打开"mysql"这个数据库，SQL如下：

mysql>use mysql;

看到结果：

Database changed

然后，更新root的密码，SQL如下：

mysql> update usersetauthentication_string=password('root')whereHost='localhost'and User='root';

最后一步：将mysqld_safe进程杀死，重启mysqld
